Until 1990, smoking cessation interventions in the Netherlands were limited. The utility and effectiveness of community-based smoking cessation programs have not been examined.
                In a treatment city (Den Bosch) a multicomponent community-based smoking cessation intervention was implemented in which local mass media and general practitioners draw smokers' attention to a local quit line. Telephone counselors advised applicants on their choice between self-help and group treatment and optional telephone counseling. Another Dutch city (Apeldoorn) served as a control. Population samples of smokers (n = 547 and n = 546) were interviewed three times at approximately 7-month intervals. Self-help manual requesters (n = 84) and group participants (n = 83) were interviewed before and 6 months after treatment.
                Treatment modalities were successful; 13% of self-help manual requesters and 22% of group participants were abstinent after 6 months. On a population level the intervention resulted in significantly higher recall of self-help manual and group program in the treatment city. A modest intervention effect on prevalence of abstinence was found at the community level.
                Treatment modalities were effective within their participants, but the intervention effectiveness on a community level was limited. No significant difference was found between quit rates after 14 months (7% in treatment city and 9% in control city). Several system failures could be identified. However, probably the intervention effect was seriously confounded by two national governmental publicity campaigns introducing and reinforcing a mandatory smoking ban and a series of national campaigns initiated by the united Dutch tobacco producers opposing the ban. Smoking reduction has been introduced as an alternative to smokers unable or unwilling to quit but has never been implemented in a population-based intervention.
                Two thousand four hundred eight daily smokers in all motivational stages were included in a randomised population-based intervention study, in Copenhagen, Denmark. Smokers, unwilling or unable to quit, were encouraged to reduce their tobacco consumption. Furthermore, smokers in the high-intensity intervention were offered participation in smoking reduction groups.
                Twenty-three percent of those who attended both baseline and 1 year visit reported reduction by at least 5 g and 8% reported a halving or more. Halving of tobacco consumption was achieved significantly more often than in the background population, OR = 2.6 (1.6-4.4), even when assuming that non-participants had not reduced, OR = 1.7 (1.0-2.8). Reduction of at least 5 g doubled the probability of increased motivation to quit and a halving increased it more than four times. The reductions were not validated. Less than 2% attended the smoking reduction groups.
                The smoking reduction intervention was significant in self-reported reduction of tobacco consumption and subsequently increased motivation to quit. This may open new perspectives, with reduction as a first step towards cessation, a possible supplement to smoking cessation strategies. The purpose of this study was to examine the effectiveness of different practice-based approaches to assist patients of primary care physicians to quit smoking and sustain cessation. Forty-four nonsmoking general practitioners volunteered for the study. After a period of training, they randomized 923 smoking clients, unselected for motivation toward quitting, to four different intervention groups: (i) minimal intervention, consisting of one single counselling session and a brief handout on quitting techniques; (ii) repeated counselling including reinforcing sessions at Months 1, 3, 6, and 9; (iii) repeated counselling and use of nicotine gum; and (iv) repeated counselling and spirometry. Biochemically validated smoking status was assessed at six and 12 months after recruitment. The proportion of verified quitters at 12 months was 4.8 percent among subjects randomized to the minimal intervention group, compared to 5.5 percent, 7.5 percent, and 6.5 percent among those randomized to the three repeated-counselling groups. In no treatment group was the outcome significantly different from that for one-time counselling at the (P less than 0.05) level. Lack of power, contamination, and low attendance at reinforcing sessions should be taken into account in interpreting the results. To test the effectiveness of a low-intensity intervention program for smoking cessation targeting the worksite environment in employees who had a low readiness to quit, we conducted an intervention trial at six intervention and six control worksites in Japan. A total of 2,307 smokers at baseline who remained at their worksite throughout the three-year study period were analyzed (1,017 in intervention and 1,290 in control groups). The multi-component program at the worksites consisted of (1) presenting information on the harms of tobacco smoking and the benefits of cessation by posters, websites, and newsletters; (2) smoking cessation campaigns for smokers; (3) advice on designation of smoking areas; and (4) periodic site-visits of the designated smoking areas by an expert researcher. At baseline, the intervention and control groups each had high prevalence of immotive or precontemplation, that reflected low readiness to quit (71.5% and 73.2%, respectively). The smoking cessation rate, as not having smoked for the preceding six months or longer, assessed at 36 months after the baseline survey by a self-administered questionnaire was significantly higher in the intervention group than the control group (12.1%, vs. 9.4%, p=0.021). The intervention program still had a significant effect on the smoking cessation rate after multiple logistic regression analysis adjusted for sex, age, type of occupation, age of starting smoking, quit attempts in the past, number of cigarettes per day, and readiness to quit (odds ratio: 1.38, 95% confidence interval: 1.05-1.81, p=0.02). The cost per additional quitter due to the intervention was calculated to be Yen 70,080. These findings indicate that this program is effective and can be implemented in similar workplaces where the prevalence of smoking is high and smokers' readiness to cease smoking is low. Nonsmokers have a potentially supportive role in tobacco cessation efforts. The present study examined the feasibility, acceptability, and potential efficacy of a telephone-based intervention for nonsmoking support persons.
                A total of 59 support persons (mean age = 36 years, 92% female, 95% White) were randomly assigned to a control condition (N = 30; written materials only) or to a social cognitive theory-based intervention (N = 29; written materials and 5 weekly, 20- to 30-min telephone counseling sessions). Both support persons and smokers completed assessments separately by mail at baseline and at weeks 6 (end of treatment) and 26.
                Two thirds of the smokers reported low-moderate levels of motivation to quit at baseline as assessed by the contemplation ladder. Study retention rates were excellent, with 95% of both support persons and smokers completing the week 26 assessment. Moreover, 86% of support persons in the intervention group completed all five telephone sessions. Treatment acceptability was high for both support persons and smokers. Compared with the control condition, the intervention was associated with a significant increase in support person self-efficacy to help their smoker (p = .034) and outcome expectancies (p = .025) from baseline to week 6. However, the intervention was not associated with higher smoking abstinence rates or quit attempts.
                The program was successful in reaching smokers with lower levels of readiness to quit. The intervention was feasible and acceptable to both support persons and smokers. Although support persons and smokers can be engaged in this type of outreach program, refinements in the intervention approach are needed to improve the smoking outcomes. Does the provision of a nurse-based intervention lead to smoking cessation in hospital patients?
                At tertiary teaching hospital in Newcastle, Australia, 4,779 eligible (aged 18-80, admitted for at least 24 hours, and able to provide informed consent) and consenting (73.4%) in-patients were recruited into a larger cross-sectional survey. 1,422 (29.7%) smokers (in the last 12 months) were randomly assigned to control (n = 711) or intervention group (n = 711). The brief nurse-delivered intervention incorporated: tailored information, assessment of withdrawal, offer of nicotine replacement therapy, booklets, and a discharge letter. Self-reported cessation at 12 months was validated with CO and salivary cotinine.
                There were no significant differences between groups in self-reported abstinence at three or 12 months post intervention, based on an intention to treat analysis. At three months, self-reported abstinence was 27.3% (I) and 27.5% (C); at 12 months was 18.5% (I) and 20.6% (C). There were no differences in validation of self-report between intervention and control groups at 12 months.
                This brief nurse-provided in-patient intervention did not significantly increase the smoking cessation rates compared with the control group at either three or 12-month follow-up.
                A systematic total quality improvement model of accountable outcome-focused treatment, incorporating assertive physician-led pharmacotherapy, routine assessment and recording of nicotine dependence (ICD 10 coding), in- and outpatient services and engagement from multidisciplinary teams of health professionals may be required to improve treatment modalities for this chronic addictive disorder. Several large and well-conducted community interventions have failed to detect an effect on prevalence of smoking.
                Two thousand four hundred eight daily smokers in all motivational stages were actively recruited and included in a randomised population-based intervention study in Copenhagen, Denmark. All smokers completed a questionnaire and underwent a health examination and a lifestyle consultation. Daily smokers in the high intensity intervention group were offered assistance to quit in smoking cessation groups.
                The validated abstinence rate at 1-year follow-up was 16.3% in the high intensity group and 12.7% in the low intensity group compared with a self-reported abstinence rate of 7.3% in the background population. The adjusted odds ratio of abstinence in the high intervention group was significantly higher, OR = 2.2 (1.6-3.0) than in the background population, also in the 'intention-to-treat' analyses, OR = 1.5 (1.1-2.0). Higher socioeconomic status, higher age at onset of daily smoking, and a higher wish to quit were predictors of success.
                In a population-based setting, using active recruitment and offering assistance to quit, it was possible to include many smokers and to achieve a significantly higher validated abstinence in the high intensity intervention than in the background population, even when using 'intention-to-treat' analyses. The AHRQ Clinical Practice Guideline for Treating Tobacco Use and Dependence recommends screening and treatment of all tobacco users. Effective methods to implement recommendations are needed because simple guideline dissemination does not necessarily result in changes in practice.
                The Guideline Implementation for Tobacco (GIFT) study tested an organizational intervention to improve Guideline implementation.
                GIFT randomized 20 Veterans Affairs medical centers to intervention or control conditions. We trained prime movers at each site to improve identification of smoking status, promote primary care interventions and increase availability of smoking cessation medications. Sites and patients were evaluated before and after intervention.
                GIFT included 20 Veterans Affairs medical centers and 5678 subjects.
                Data regarding smoking status, delivery of treatment, medication use, and smoking cessation were collected from participant surveys, medical record review, survey of site leaders, and Pharmacy Benefits Management.
                The intervention did not increase participant report of being asked about smoking status or receipt of counseling. It did increase the rate of identification of smoking status in the medical record (P = 0.0001) but did not increase the rate of counseling to stop smoking. Site level data showed no increase in the number of patients receiving smoking cessation medications or dollars spent on medications. Individual smoker data showed a significant increase in the use of medications for smoking cessation in intervention sites (odds ratio = 6.89, P < 0.0001); however, only a small minority of smokers received medication even after the intervention. There was no difference in smoking cessation rates between participants at the intervention and treatment sites.
                We conclude that improvements in smoking cessation rates are likely to require more intensive intervention in this population. Despite extremely high rates of smoking among individuals with psychotic disorders and the associated financial and health costs, few studies have investigated the efficacy of smoking cessation interventions among this group. The purpose of this study was to compare an integrated psychological and nicotine replacement therapy intervention for people with a psychotic disorder with routine care alone.
                The authors recruited 298 regular smokers with a psychotic disorder residing in the community and randomly assigned them to a routine care comparison condition (N=151) or an eight-session, individually administered smoking cessation intervention (N=147), which consisted of nicotine replacement therapy, motivational interviewing, and cognitive behavior therapy. Outcome variables included continuous and point-prevalence abstinence rates, smoking reduction status, and changes in symptoms and functioning.
                While there were no overall differences between the treatment group and comparison group in abstinence rates, a significantly higher proportion of smokers who completed all treatment sessions stopped smoking at each of the follow-up occasions (point-prevalence rates: 3 months, 30.0% versus 6.0%; 6 months, 18.6% versus 4.0%; and 12 months, 18.6% versus 6.6%). Smokers who completed all treatment sessions were also more likely to have achieved continuous abstinence at 3 months (21.4% versus 4.0%). There was a strong dose-response relationship between treatment session attendance and smoking reduction status, with one-half of those who completed the intervention program achieving a 50% or greater reduction in daily cigarette consumption across the follow-ups, relative to less than one-fifth of the comparison subjects. There was no evidence of any associated deterioration in symptoms or functioning.
                These findings demonstrate the utility of a nicotine replacement therapy plus motivational interviewing/cognitive behavior therapy smoking cessation intervention among individuals with a psychotic disorder. Further development of more efficacious interventions is required for those who do not respond to existing interventions. One of the key goals of health promotion strategies in the UK and other developed countries is to reduce the prevalence of cigarette consumption. While overall smoking rates in the UK have fallen over the last few decades, they have barely fallen for the least advantaged adults (Department of Health, 1998a). There is a need for interventions that are suitable for lower socio-economic status (SES) smokers that have undergone rigorous evaluation. This study describes a randomized controlled trial of cognitive behaviour therapy (CBT) with smokers from a deprived area of London. At 6 months follow-up, 21 (17.2%) of 122 participants receiving therapy were abstinent and 14 (11.5%) had reduced cigarette consumption by at least 25% of pre-treatment level. Six (5.6%) of 107 participants in the control group were abstinent and none had reduced consumption. These results suggest that this self-help CBT intervention has the potential to reduce the prevalence of smoking among lower SES smokers. To test the efficacy of (i) computer-generated tailored letters and (ii) practitioner-delivered brief advice for smoking cessation against an assessment-only condition; and to compare both interventions directly.
                Quasi-randomized controlled trial.
                A total of 34 randomly selected general practices from a German region (participation rate 87%).
                A total of 1499 consecutive patients aged 18-70 years with daily cigarette smoking (participation rate 80%).
                The tailored letters intervention group received up to three individualized personal letters. Brief advice was delivered during routine consultation by the practitioner after an onsite training session. Both interventions were based on the Transtheoretical Model of behaviour change.
                Self-reported point prevalence and prolonged abstinence at 6-, 12-, 18- and 24-month follow-ups.
                Among participants completing the last follow-up, 6-month prolonged abstinence was 18.3% in the tailored letters intervention group, 14.8% in the brief advice intervention group and 10.5% in the assessment-only control group. Assuming those lost to follow-up to be smokers, the rates were 10.2%, 9.7% and 6.7%, respectively. Analyses including all follow-ups confirmed statistically significant effects of both interventions compared to assessment only. Using complete case analysis, the tailored letters intervention was significantly more effective than brief advice for 24-hour [odds ratio (OR) = 1.4; P = 0.047] but not for 7-day point prevalence abstinence (OR = 1.4; P = 0.068) for prolonged abstinence, or for alternative assumptions about participants lost to follow-up.
                The study demonstrated long-term efficacy of low-cost interventions for smoking cessation in general practice. The interventions are suitable to reach entire populations of general practices and smoking patients. Computer-generated letters are a promising option to overcome barriers to provide smoking cessation counselling routinely. The Quit and Win Challenge, an incentive-based intervention, was implemented in two counties in Eastern Ontario to encourage adult smokers to quit smoking. Participants (n = 231) were compared with adult smokers selected at random (n = 385) from a larger, four-county area. Baseline characteristics were assessed by telephone interview, including socio-demographic and smoking-related factors. Follow-up interviews were also conducted by telephone. Initial and follow-up response rates were high (over 84%) in both groups. Compared with the random survey group, Quit and Win participants tended to be younger, more educated, employed and heavier smokers, with fewer friends or co-workers who smoked. After one year, 19.5% of them reported that they were smoke-free, whereas less than 1% of the random group had achieved cessation. This translates into an impact rate of 0.17%, affecting 1 in 588 adult smokers. With the exception of the smokers' baseline "stage of change," none of the socio-demographic or smoking factors was predictive of cessation. We conclude that this intervention achieved only limited success and attracted certain sectors of the community disproportionately, i.e. smokers who were highly motivated to quit. We argue that increased access to proven cessation therapies would improve the impact of such interventions. This paper presents results from a preliminary short-term work-site intervention study aimed at smoking cessation. The 3-month intervention included consultation for employers on the adoption of a nonsmoking policy, training for nonsmokers to provide assistance to smokers attempting to quit, and cessation classes for smokers. Eight work sites from Bloomington, Minnesota were recruited to the study and randomly assigned to an intervention or comparison condition after a baseline survey of all employees. To assess the effect of the intervention, smokers were surveyed 1 and 6 months after the intervention was completed. At the 1-month follow-up, the overall quit rate in the intervention group was 12% compared to 5% in the control group (P < .05). At the 6-month follow-up, 12% of smokers in the intervention group reported quitting, compared to 9% in the control group (P < .05). Co-worker support for quitting was higher in the intervention group compared to the comparison group. Cessation was highest overall among smokers whose co-workers frequently asked them not to smoke and among those who worked with a high proportion of nonsmokers. These results indicate that a short-term, multifaceted smoking cessation program implemented in work sites can affect smoking cessation rates as well as the work-site norms about smoking. This article reports on one of the few experimental studies in Europe to examine work site smoking cessation. The study examined whether a comprehensive intervention (self-help manuals, group courses, a mass media campaign, smoking policies, and a second-year program) is more effective than a minimal intervention (self-help manuals only). Eight work sites participated in the study. The effect of treatment on smoking cessation depended on nicotine dependency levels: Heavy smokers had more success with the comprehensive smoking cessation intervention than with the minimal intervention (with respect to both 14-month quit rate and 6-month prolonged abstinence). For heavy smokers, exposure to mass media exhibitions or to group courses had a beneficial effect on prolonged abstinence. Comprehensive programs may be most appropriate in Dutch work sites with large proportions of heavily addicted smokers. Smokers requesting self-help materials for smoking cessation (N = 2,021) were randomized to receive (a) an experimental self-quitting guide emphasizing nicotine fading and other nonaversive behavioral strategies, (b) the same self-quitting guide with a support guide for the quitter's family and friends, (c) self-quitting and support guides along with four brief counselor calls, or (d) a control guide providing motivational and quit tips and referral to locally available guides and programs. Subjects were predominantly moderate to heavy smokers with a history of multiple previous quit attempts and treatments. Control subjects achieved quit rates similar to those of smokers using the experimental quitting guide, with fewer behavioral prequitting strategies and more outside treatments. Social support guides had no effect on perceived support for quitting or on 8- and 16-month quit rates. Telephone counseling increased adherence to the quitting protocol and quit rates. Few studies have rigorously evaluated whether providing biologically based health-risk feedback is more effective than standard interventions in increasing smokers' motivation to quit and their long-term abstinence.
                An RCT was conducted from 2005 to 2008. Data were analyzed in 2008.
                Smokers (N=536) were recruited from the community, regardless of their interest in quitting smoking.
                Smokers either received brief ( approximately 20 minutes), personally tailored counseling sessions based on their lung functioning, carbon monoxide (CO) exposure, and smoking-related health conditions, or they received generic smoking-risk information and personalized counseling about their diet, BMI, and physical activity. All were advised to quit smoking and were offered access to a free phone-counseling program.
                Treatment utilization and abstinence at 6 and 12 months post-intervention.
                Participants who received the experimental treatment demonstrated no greater motivation to quit, use of treatment services, or abstinence compared to controls at either follow-up assessment. In fact, controls reported greater motivation to quit at 12 months (M 3.42 vs 3.20, p=0.03), greater use of pharmacotherapy at 6 months (37.8% vs 28.0%, p=0.02), and greater 30-day point prevalent abstinence at 6 months, after controlling for relevant covariates (10.8% vs 6.4%, adjusted p=0.04).
                The present study found no support for adding a personalized health-risk assessment emphasizing lung health and CO exposure to generic cessation advice and counseling for community-based smokers not otherwise seeking treatment.
                NCT00169260. To evaluate the impact of a classroom-based, Web-assisted tobacco intervention addressing smoking prevention and cessation with adolescents.
                A two-group randomized control trial with 1,402 male and female students in grades 9 through 11 from 14 secondary schools in Toronto, Canada. Participants were randomly assigned to a tailored Web-assisted tobacco intervention or an interactive control condition task conducted during a single classroom session with e-mail follow-up. The cornerstone of the intervention was a five-stage interactive Web site called the Smoking Zine (http://www.smokingzine.org) integrated into a program that included a paper-based journal, a small group form of motivational interviewing, and tailored e-mails.
                Resistance to smoking, behavioral intentions to smoke, and cigarette use were assessed at baseline, postintervention, and three- and six-month follow-up. Multilevel logistic growth modeling was used to assess the effect of the intervention on change over time.
                The integrated Smoking Zine program helped smokers significantly reduce the likelihood of having high intentions to smoke and increased their likelihood of high resistance to continued cigarette use at 6 months. The intervention also significantly reduced the likelihood of heavy cigarette use adoption by nonsmokers during the study period.
                The Smoking Zine intervention provided cessation motivation for smokers most resistant to quitting at baseline and prevented nonsmoking adolescents from becoming heavy smokers at 6 months. By providing an accessible and attractive method of engaging young people in smoking prevention and cessation, this interactive and integrated program provides a novel vehicle for school- and population-level health promotion. To evaluate a training workshop for community pharmacy personnel to improve their counselling in smoking cessation based on the stage-of-change model.
                A randomised controlled trial of community pharmacies and pharmacy customers.
                All 76 non-city community pharmacies registered in Grampian, Scotland, were invited to participate. Sixty-two pharmacies (82%) were recruited.
                All the intervention pharmacy personnel were invited to attend the training; 40 pharmacists and 54 assistants attended. A total of 492 customers who smoked (224 intervention, 268 controls) were recruited during the 12-month recruitment period (overall recruitment rate 63%).
                The perceptions of customers and pharmacy personnel of the pharmacy support and self-reported smoking cessation rates for the two groups of customers at one, four, and nine months.
                The intervention customer respondents were significantly more likely to have discussed stopping smoking with pharmacy personnel, 85% (113) compared with 62% (99) of the controls (p < 0.001). The former also rated their discussion more highly; 34% (45) of the intervention customers compared with 16% (25) of the controls rated it as "very useful" (p = 0.048). Assuming non-responders had lapsed, one-month point prevalence of abstinence was claimed by 30% of intervention customers and 24% of controls (p = 0.12); four months' continuous abstinence was claimed by 16% of intervention customers and 11% of controls (p = 0.094); and nine months' continuous abstinence was claimed by 12% of intervention customers and 7% of controls (p = 0.089). These trends in outcome were not affected by potential confounders (sex, age, socioeconomic status, nicotine dependence, and type of nicotine replacement product used) or adjustment for clustering.
                The intervention was associated with increased and more highly rated counselling, and a trend toward higher smoking cessation rates, indicating that community pharmacy personnel have the potential to make a significant contribution to national smoking cessation targets. Evaluate the feasibility, acceptability, and potential efficacy of a skills-training intervention for adults interested in helping someone to stop smoking (i.e., support persons).
                Sixty adult support persons (77% female) were directly recruited from the community and randomly assigned to this intervention (manual plus five weekly group-based sessions) or a control condition (one-page leaflet). All intervention and outcome assessments occurred through the support persons. Assessments occurred at weeks 0 (baseline), 6 (end of treatment), 12, and 24. The study was conducted from 1998 to 2001; data collection occurred from 1999 to 2000. Outcomes were ratings of treatment acceptability, recruitment and retention rates, supportive behaviors provided to the smoker, and smoking behavior change in the smoker as reported by the support person.
                Support persons were recruited in a timely manner and study retention rates were high. Support persons in skills training showed significant increases in their supportive behavior scores compared with control subjects at weeks 6 and 12. Although not statistically significant, the skills-training intervention was associated with more quit attempts, greater improvement in stage of change, and higher 7-day point prevalence abstinence rates in the smokers than the control condition.
                A skills training intervention for support persons is feasible and acceptable. Further studies are needed to test the efficacy of this approach for smoking cessation. The purpose of this study was to evaluate the impact of a tobacco cessation intervention using motivational interviewing on smoking cessation rates during diabetes self-management training (DSMT).
                A randomized controlled trial was conducted with subjects recruited from an ongoing type 2 diabetes adult education program at a large diabetes center. A total of 114 subjects were randomized to intervention (n = 57; face-to-face motivational interviewing plus telephone counseling and offering of medication) or standard care (n = 57). Outcome measures included tobacco cessation rates, mean number of cigarettes smoked, A1C, weight, blood pressure, and lipids.
                Intensive intervention using motivational interviewing integrated into a standard DSMT program resulted in a trend toward greater abstinence at 3 months of follow-up in those receiving the intervention. However, this same trend was not observed at 6 months. The addition of this structured smoking cessation intervention did not negatively affect either diabetes education or other measures of diabetes management, including A1C values.
                Structured tobacco cessation efforts can be readily integrated into established diabetes education programs without a negative impact on diabetes care or delivery of diabetes education. However, an intervention of moderate intensity for smoking cessation was no more effective than usual care in assisting patients with tobacco cessation after 6-month follow-up. Whether a more intensive intervention, targeting patients expressing a readiness to discontinue tobacco use, and/or a longer duration or a more cumulative effect of treatment will be more effective must be evaluated. To assess the effectiveness of a smoking cessation intervention at the workplace. The intervention was adapted to smokers' tobacco dependence, and included minimal structured counselling at the first visit (5-8 minutes), nicotine patches for three months, and three sessions of counselling for reinforcement of abstinence (2-3 minutes) over a three month period.
                Open randomised trial with two groups: the intervention group, and the control group which was subjected to standard clinical practice, consisting of short (30 seconds to one minute) sporadic sessions of unstructured medical antismoking advice. The trial was carried out among 217 smokers of both sexes, aged 20-63 years, motivated to quit smoking and without contraindications for nicotine patches, who were employees at a public transport company and at two worksites of an electric company. The main outcome measure was self reported tobacco abstinence confirmed by carbon monoxide in expired air </=10 ppm. Analysis was performed according to intention-to-treat.
                The rate of continuous abstinence at 12 months was 20.2% for the intervention versus 8.7% for the control group (OR: 2.58; 95% CI: 1.13 to 5.90; p = 0.025). In subgroup analyses, effectiveness of the intervention did not vary substantially with age, tobacco dependence, number of cigarettes smoked per day, number of years of tobacco consumption, degree of desire to quit smoking, time spent with smokers, subjective health, and presence of tobacco related symptoms. Weight gain at 12 months was similar for both groups (1.69 kg in the intervention v 2.01 kg in the control group; p = 0.21).
                A simple and easily generalisable intervention at the workplace is effective to achieve long term smoking cessation. In a setting similar to ours, nine subjects would have to be treated for three months for one to achieve continuous abstinence for 12 months. Physician-delivered advice to stop smoking is effective, but time demands often reduce the number of smokers who receive assistance. We evaluated three nurse-assisted interventions designed to minimize physician burden and increase counseling in primary care settings.
                Randomized controlled trial with a 12-month follow-up.
                Internal medicine and family practice offices in a health maintenance organization.
                Smokers (n = 3161) who were patients of participating physicians or other medical care providers (n = 60).
                Medical care providers delivered a 30-second stop-smoking prompt to 2707 smokers and referred them to an on-site nurse smoking counselor. The nurse randomly provided a two-page pamphlet (advice control) or one of three nurse-assisted interventions: 1) self-quit training; 2) referral to a group cessation program; or 3) a combination of self-quit training and referral. Each nurse-delivered intervention included a 10-minute video, written materials, and a follow-up phone call.
                Physicians delivered brief advice to 86% of identified smokers during the 1-year program. The proportion of participants reporting abstinence after both 3 and 12 months of follow-up nearly doubled (P = 0.01) for the nurse-assisted self-quit (7.1%), group-referral (7.6%), and combination (6.9%) interventions, compared to brief physician advice alone (3.9%) (P < 0.05). Saliva cotinine tests confirmed these effects (P < 0.004), although quit rates were lower (3.4%, 4.7%, 4.3%, and 2.3%, respectively) because roughly one half of quitters chose not to provide a saliva sample and were counted as smokers.
                Involving nurses in counseling smokers reduces physician burden, makes counseling more likely, and significantly increases cessation rates compared with brief physician advice alone. This prospective randomized study examined the impact of three tailored intervention approaches to increase quitting rates among African-American smokers who were clients of a community health center that serves primarily low-income and indigent persons. Smokers were randomized to one of three groups: (1) health care provider prompting intervention alone, (2) health care provider prompting intervention with tailored print communications, and (3) health care provider prompting intervention with tailored print communications and tailored telephone counseling. Among the 160 smokers who completed the study, 35 (21.8%) had quit smoking at follow-up. Smokers who received the provider prompting intervention with tailored print materials were more likely to report having quit than smokers who received the provider intervention alone (32.7% vs. 13.2%, p < 0.05). Smokers who received all three intervention components were not more likely to report having quit at follow-up than those who only received the provider intervention (19.2% vs. 13.2%). Smokers who at baseline were less educated, smoked less than half a pack of cigarettes per day, had a stronger desire to quit, felt more efficacious, and had thought about quitting were more likely to report having quit at follow-up. These results provide support for continued refinement of tailored communications to aid smoking cessation among African-American smokers. To test whether high school students' participation in advocacy activities related to the advertising, availability, and use of tobacco in their communities would prevent or reduce their own tobacco use.
                Ten continuation high schools in northern California, randomly assigned to a semester-long program in which students either carried out advocacy activities to counter environmental-level smoking influences in their communities (treatment) or learned about drug and alcohol abuse prevention (control).
                Eleventh and 12th grade high school students; 5 (advocacy) treatment and 5 control schools over 4 semesters from 2000 through 2002.
                Self-reported smoking defined as nonsmokers (those who had never smoked tobacco or those who were former smokers), light smokers (those who smoked <1 pack per week), or regular smokers (those who smoked >or=1 pack per week), and confirmed by carbon monoxide level readings. The following 3 constructs related to social cognitive theory- perceived incentive value, perceived self-efficacy, and outcome expectancies-were assessed.
                There was a significant net change from baseline to the end of the semester (after the intervention) between treatment and control schools for students who were regular smokers, but not for students who were nonsmokers or light smokers. Regular smoking decreased 3.8% in treatment schools and increased 1.5% in control schools (P<.001). Regular smoking continued to decrease at 6 months after the intervention in treatment schools, with a total change in prevalence from 25.1% to 20.3%. Involvement in community-advocacy activities and the 3 social constructs-perceived incentive value, perceived self-efficacy, and outcome expectancies-also showed significant net changes between treatment and control schools (all P values <.01).
                Student engagement in community-advocacy activities that addressed environmental influences of cigarette smoking resulted in significant decreases in regular smoking. New training programs need to be developed to help Chinese smokers achieve quitting. The objective of this study was to assess the effectiveness of a group smoking cessation intervention based on social cognitive theory among Chinese smokers.
                A total of 225 smokers were eligible for the study and were randomly assigned to an intervention group (n=118) and a control group (n=107). The intervention group received the course soon after a baseline survey, whereas the control group received routine training in the first 6 months, and then took the same course. Effectiveness was evaluated at 6-month and 1-year follow-up from baseline.
                After 6 months, 40.5% (47/116) in the intervention group and 5.0% (5/101) in the control group quit smoking (absolute risk reduction: 35.5% [95% confidence interval (CI): 24.2-46.8%]). The 6-month continuous abstinence rate was 28.4% (33/116) in the intervention group and 3.0% (3/101) in the control group (absolute risk reduction 25.4% [95% CI: 15.6-35.2%]). At 1-year follow-up, the proportion of quitting and the 6-month abstinence rate in the intervention group were 35.8% and 22.0%, respectively. The factors associated with smoking cessation during the 6 month period were intervention (adjusted odds ratio [OR]=6.42 [95% CI: 2.46-13.28]), as well as anticipation of quitting (adjusted OR=1.46 [95% CI: 1.12-1.91]) and skill self-efficacy score in the baseline (adjusted OR=1.04 [95% CI: 1.01-1.07]). The same intervention was conducted in the control group after the 6-month study, in which a similar intervention effect was observed.
                A smoking cessation intervention based on social cognitive theory among Chinese smokers is highly effective. This study evaluated an attempt at 38 workplaces to help employees stop or reduce their levels of smoking. In past research, worksite support groups, in combination with a media smoking cessation program and self-help manuals, were found to be effective in helping employees quit smoking. Unfortunately, recidivism was found at the follow-up evaluations. The present study replicated the results of the previous worksite smoking cessation program with support groups, a television intervention, and self-help manuals. At this postpoint, 42% of employees provided groups plus incentives were abstinent compared to only 15% who were only provided self-help materials. An important difference in this study was that there were also monthly follow-up support groups and incentives. Work settings can be a source of stress and conflict, which can precipitate relapse. At a 12-month follow-up, 26% of those participants who were provided support and incentives were abstinent compared to 16% who were only provided the self-help materials. New educational programs must be developed to improve physicians' skills and effectiveness in counseling patients about smoking cessation.
                To assess the efficacy of an educational program based on behavioral theory, active learning methods, and practice with standardized patients in helping patients abstain from smoking and changing physicians' counseling practices.
                Cluster randomized, controlled trial.
                Two general internal medicine clinics in Switzerland.
                35 residents and 251 consecutive smoking patients.
                A training program administered over two half-days, during which physicians learned to provide counseling that matched smokers' motivation to quit and practiced these skills with standardized patients acting as smokers at different stages of change. The control intervention was a didactic session on management of dyslipidemia.
                Self-reported abstinence from smoking at 1 year of follow-up, which was validated by exhaled carbon monoxide testing at one clinic; score of overall quality of counseling based on use of 14 counseling strategies; patient willingness to quit; and daily cigarette consumption.
                At 1 year of follow-up, abstinence from smoking was significantly higher in the intervention group than in the control group (13% vs. 5%; P = 0.005); this corresponded to a cluster-adjusted odds ratio of 2.8 (95% CI, 1.4 to 5.5). Residents who received the study training provided better counseling than did those who received the control training (mean score, 4.0 vs. 2.7; P = 0.002). Smokers' willingness to quit was also higher in the intervention group (94% vs. 80%; P = 0.007). A nonsignificant trend toward lower daily cigarette consumption in the intervention group was observed.
                A training program in smoking cessation administered to physicians that was based on behavioral theory and practice with standardized patients significantly increased the quality of physicians' counseling, smokers' motivation to quit, and rates of abstinence from smoking at 1 year. Few smoking cessation self-help materials are available for smokers who are not planning to quit. However, computer-tailored interventions can be designed specifically for these smokers.
                In a large randomized field trial (N = 843), two different tailored smoking cessation self-help interventions (multiple tailoring and single tailoring) and one standardized smoking cessation self-help guide were compared with a no-information control group and with each other. The contents of the tailored interventions were adapted to individuals' self-reported stage of change, outcome expectations, self-efficacy levels, and smoking behavior.
                The primary outcome measure was forward stage transition. The standardized self-help guide had no effect. Among smokers who were not planning to quit within the next 5 years the multiple-tailored intervention was more effective than the single-tailored intervention. This pattern was supported by the cognitive changes caused by the interventions. Among smokers who were planning to quit within the next 5 years but not within the next 6 months, none of the self-help materials had any effect.
                The present results show that the self-help material currently available in the Netherlands, the standardized self-help guide, was not effective among smokers with low readiness to change. However, computer-generated tailored interventions seem a promising means of communicating information on smoking and smoking cessation to these smokers. Happy Ending (HE) is an intense 1-year smoking cessation program delivered via the Internet and cell phone. HE consists of more than 400 contacts by email, Web pages, interactive voice response, and short message service technology. HE includes a craving helpline and a relapse prevention system, providing just-in-time therapy. All the components of the program are fully automated.
                The objectives were to describe the rationale for the design of HE, to assess the 12-month efficacy of HE in a sample of smokers willing to attempt to quit without the use of nicotine replacement therapy, and to explore the potential effect of HE on coping planning and self-efficacy (prior to quitting) and whether coping planning and self-efficacy mediate treatment effect.
                A two-arm randomized controlled trial was used. Subjects were recruited via Internet advertisements and randomly assigned to condition. Inclusion criteria were willingness to quit on a prescribed day without using nicotine replacement and being aged 18 years or older. The intervention group received HE, and the control group received a 44-page self-help booklet. Abstinence was defined as "not even a puff of smoke, for the last seven days" and was assessed by means of Internet surveys or telephone interviews 1, 3, 6, and 12 months postcessation. The main outcome was repeated point abstinence (ie, abstinence at all four time points). Coping planning and self-efficacy were measured at baseline and at the end of the preparation phase (ie, after 2 weeks of treatment, but prior to cessation day).
                A total of 290 participants received either the HE intervention (n=144) or the control booklet (n=146). Using intent-to-treat analysis, participants in the intervention group reported clinically and statistically significantly higher repeated point abstinence rates than control participants (20% versus 7%, odds ratio [OR] = 3.43, 95% CI = 1.60-7.34, P = .002). Although no differences were observed at baseline, by the end of the preparation phase, significantly higher levels of coping planning (t(261) = 3.07, P = .002) and precessation self-efficacy (t(261) = 2.63, P = .01) were observed in the intervention group compared with the control group. However, neither coping planning nor self-efficacy mediated long-term treatment effect. For point abstinence 1 month after quitting, however, coping planning and self-efficacy showed a partial mediation of the treatment effect.
                This 12-month trial documents a long-term treatment effect of a fully automated smoking cessation intervention without the use of nicotine replacement therapy. The study adds to the promise of using digital media in supporting behavior change. To examine the population impact and effectiveness of the Pro-Change smoking cessation course based on the Transtheoretical Model (TTM) compared to standard self-help smoking cessation literature.
                Randomized controlled trial.
                Sixty-five West Midlands general practices.
                Randomly sampled patients recorded as smokers by their general practitioners received an invitation letter and 2471 current smokers agreed.
                Responders were randomized to one of four interventions. The control group received standard self-help literature. In the Manual intervention group, participants received the Pro-Change system, a self-help workbook and three questionnaires at 3-monthly intervals, which generated individually tailored feedback. In the Phone intervention group, participants received the Manual intervention plus three telephone calls. In the Nurse intervention group, participants received the Manual intervention plus three visits to the practice nurse.
                Biochemically confirmed point prevalence of being quit and 6-month sustained abstinence, 12 months after study commencement.
                A total of 9.1% of registered current smokers participated, of whom 83.0% were not ready to quit. Less than half of participants returned questionnaires to generate second and third individualized feedback. Telephone calls reached 75% of those scheduled, but few participants visited the nurse. There were small differences between the three Pro-Change arms. The odds ratio (95% confidence intervals) for all Pro-Change arms combined versus the control arm were 1.50 (0.85-2.67) and 1.53 (0.76-3.10), for point prevalence and 6-month abstinence, respectively. This constitutes 2.1% of the TTM group versus 1.4% of the control group achieving confirmed 6-month sustained abstinence.
                There was no statistically significant benefit of the intervention apparent in this trial and the high relapse of quitters means that any population impact is small. Initial trials of web-based smoking-cessation programs have generally been promising. The active components of these programs, however, are not well understood. This study aimed to (1) identify active psychosocial and communication components of a web-based smoking-cessation intervention and (2) examine the impact of increasing the tailoring depth on smoking cessation.
                Randomized fractional factorial design.
                Two HMOs: Group Health in Washington State and Henry Ford Health System in Michigan.
                1866 smokers.
                A web-based smoking-cessation program plus nicotine patch. Five components of the intervention were randomized using a fractional factorial design: high- versus low-depth tailored success story, outcome expectation, and efficacy expectation messages; high- versus low-personalized source; and multiple versus single exposure to the intervention components.
                Primary outcome was 7 day point-prevalence abstinence at the 6-month follow-up.
                Abstinence was most influenced by high-depth tailored success stories and a high-personalized message source. The cumulative assignment of the three tailoring depth factors also resulted in increasing the rates of 6-month cessation, demonstrating an effect of tailoring depth.
                The study identified relevant components of smoking-cessation interventions that should be generalizable to other cessation interventions. The study also demonstrated the importance of higher-depth tailoring in smoking-cessation programs. Finally, the use of a novel fractional factorial design allowed efficient examination of the study aims. The rapidly changing interfaces, software, and capabilities of eHealth are likely to require such dynamic experimental approaches to intervention discovery. In Japan, the prevalence of smoking among males and females was 56.1% and 14.2%, respectively, in 1997. Male smoking prevalence was exceedingly high as compared to those in other industrialized countries. We conducted a randomized controlled intervention study on smoking cessation for all smokers in a worksite regardless of their willingness to quit smoking. All of the male smokers in a radiator manufacturing factory (n=263) were randomly allocated to an intervention group (n=132) or a control group (n=131). Subjects in the intervention group received individual counseling by a doctor, and those who signed a Smoking Cessation Declaration underwent a five-month intervention. Subjects in the control group received equivalent delayed intervention for four months. The cessation rate after the original intervention was 12.9% (17/132) and 3.1% (4/131) in the intervention and control groups, respectively (p=0.003). Among those who once succeeded in quitting, 48.6% (18/37) maintained cessation at the long-term survey. Overall, the cessation rate was 8.4% (22/263) and the prevalence of smoking among males significantly decreased from 62.9 to 56.7% (p=0.038). As a conclusion, intervention in all smokers at a worksite regardless of their willingness to quit is effective and impacts the overall smoking rate. Brief advice for smoking patients has not been sufficiently integrated in routine care. Computer-based interventions emerged as a time saving option that might help to exhaust the potential population impact of the general practice setting.
                151 practices were randomly assigned to one of three intervention programs consisting in the delivery of: (1) brief advice by the practitioner; (2) individually tailored computer-generated letters; or (3) a combination of both interventions. We assessed three dimensions of population impact: (1) adoption, i.e., the rate of practices participating in the program; (2) reach, measured as the number of interventions provided within 7 months; (3) effectiveness, measured as smoking abstinence at 12-months follow-up.
                Among the practices, 70% adopted the program with no significant differences across study groups. Treatment was provided to 3086 adult smokers. Negative binomial regression analysis revealed that the number of interventions provided was higher in practices allocated to the tailored letter and combination intervention groups by 215% (p<.01) and 127% (p=.02), respectively, compared to the brief advice intervention group. Among the patients who received the combination of both intervention, the odds of point abstinence from smoking was increased by 65% (p=.02) and 32% (p=.01) compared to the brief advice and tailored letters intervention respectively. Comparing the number of abstinent patients at follow-up revealed that the tailored letter and combination interventions were superior to the brief advice intervention.
                Computer-based interventions alone or in addition to conventional practitioner-delivered advice can foster the participation of general medical practices in tobacco control.

Schools in many countries undertake programmes for smoking prevention, but systematic reviews have shown mixed evidence of their effectiveness. Most peer-led approaches have been classroom-based, and rigorous assessments are scarce. We assessed the effectiveness of a peer-led intervention that aimed to prevent smoking uptake in secondary schools.
                We undertook a cluster randomised controlled trial of 10 730 students aged 12-13 years in 59 schools in England and Wales. 29 schools (5372 students) were randomly assigned by stratified block randomisation to the control group to continue their usual smoking education and 30 (5358 students) to the intervention group. The intervention (ASSIST [A Stop Smoking In Schools Trial] programme) consisted of training influential students to act as peer supporters during informal interactions outside the classroom to encourage their peers not to smoke. Follow-up was immediately after the intervention and at 1 and 2 years. Primary outcomes were smoking in the past week in both the school year group and in a group at high risk of regular smoking uptake, which was identified at baseline as occasional, experimental, or ex-smokers. Analysis was by intention to treat. This study is registered, number ISRCTN55572965.
                The odds ratio of being a smoker in intervention compared with control schools was 0.75 (95% CI 0.55-1.01) immediately after the intervention (n=9349 students), 0.77 (0.59-0.99) at 1-year follow-up (n=9147), and 0.85 (0.72-1.01) at 2-year follow-up (n=8756). The corresponding odds ratios for the high-risk group were 0.79 (0.55-1.13 [n=3561]), 0.75 (0.56-0.99 [n=3483]), and 0.85 (0.70-1.02 [n=3294]), respectively. In a three-tier multilevel model with data from all three follow-ups, the odds of being a smoker in intervention compared with control schools was 0.78 (0.64-0.96).
                The results suggest that, if implemented on a population basis, the ASSIST intervention could lead to a reduction in adolescent smoking prevalence of public-health importance. Brief advice to stop smoking from general practitioners (GPs) has been repeatedly shown to increase smoking cessation by a small, but measurable amount. Some studies have suggested that adding more intensive interventions to brief advice may increase its effectiveness, but it is unclear whether this is true in general practice.
                To determine whether brief advice from a doctor together with counselling and follow-up from a trained practice nurse is more effective than brief advice alone in helping people to stop smoking.
                The design was a randomized controlled trial. Four hundred and ninety-seven general practice patients aged older than 18 years and smoking at least one cigarette per day in six general practices in Oxfordshire, Berkshire, and Buckinghamshire were randomized to one of two interventions: brief verbal or written advice from a GP plus extended counselling and follow-up from a trained practice nurse; brief advice from a GP alone. The primary outcome was sustained abstinence from smoking at three and 12 months. A secondary outcome was forward movement in the stages of change cycle.
                The proportion showing sustained abstinence was 3.6% in the extended counselling group, and 4.4% in the brief advice group (difference = -0.8%; 95% confidence interval = -4.3% to 2.6%). Seventy-four (30%) of those randomized to extended counselling actually took up this offer. No significant progression in stages of change was detected between the two groups.
                In unselected general practice patients who smoke, brief advice from a GP combined with intensive intervention and follow-up by a practice nurse is no more effective than brief advice alone. The Internet is a promising venue for delivering smoking cessation treatment, either as a stand-alone program or as an adjunct to pharmacotherapy. However, there is little data to indicate what percent of smokers are interested in receiving online smoking cessation services or how best to recruit smokers to Internet-based programs.
                Using a defined recruitment sample, this study aimed to identify the percentage of smokers who expressed interest in or enrolled in Project Quit, a tailored, online, cognitive-behavioral support program offered with adjunctive nicotine replacement therapy patches. In addition, we examined the effectiveness of several individual-level versus population-level recruitment strategies.
                Members from two large health care organizations in the United States were invited to participate in Project Quit. Recruitment efforts included proactive invitation letters mailed to 34533 likely smokers and reactive population-level study advertisements targeted to all health plan members (> 560000 adults, including an estimated 98000 smokers across both health care organizations).
                An estimated 1.6% and 2.5% of adult smokers from each health care organization enrolled in Project Quit. Among likely smokers who received proactive study invitations, 7% visited the Project Quit website (n = 2260) and 4% (n = 1273) were eligible and enrolled. Response rates were similar across sites, despite using different sources to assemble the invitation mailing list. Proactive individual-level recruitment was more effective than other forms of recruitment, accounting for 69% of website visitors and 68% of enrollees.
                Smokers were interested in receiving online smoking cessation support, even though they had access to other forms of treatment through their health insurance. Uptake rates for this program were comparable to those seen when smokers are advised to quit and are referred to other forms of smoking cessation treatment. In this sample, proactive mailings were the best method for recruiting smokers to Project Quit. The Hutchinson Study of High School Smoking randomized trial was designed to rigorously evaluate a proactive, personalized telephone counseling intervention for adolescent smoking cessation.
                Fifty randomly selected Washington State high schools were randomized to the experimental or control condition. High school junior smokers were proactively identified (N = 2151). Trained counselors delivered the motivational interviewing plus cognitive behavioral skills training telephone intervention to smokers in experimental schools during their senior year of high school. Participants were followed up, with 88.8% participation, to outcome ascertainment more than 1 year after random assignment. The main outcome was 6-months prolonged abstinence from smoking. All statistical tests were two-sided.
                The intervention increased the percentage who achieved 6-month prolonged smoking abstinence among all smokers (21.8% in the experimental condition vs 17.7% in the control condition, difference = 4.0%, 95% confidence interval [CI] = -0.2 to 8.1, P = .06) and in particular among daily smokers (10.1% vs 5.9%, difference = 4.1%, 95% CI = 0.8 to 7.1, P = .02). There was also generally strong evidence of intervention impact for 3-month, 1-month, and 7-day abstinence and duration since last cigarette (P = .09, .015, .01, and .03, respectively). The intervention effect was strongest among male daily smokers and among female less-than-daily smokers.
                Proactive identification and recruitment of adolescents via public high schools can produce a high level of intervention reach; a personalized motivational interviewing plus cognitive behavioral skills training counseling intervention delivered by counselor-initiated telephone calls is effective in increasing teen smoking cessation; and both daily and less-than-daily teen smokers participate in and benefit from telephone-based smoking cessation intervention. Smoking cessation counseling is an important element of tobacco control in the workplace, but it is not easy to persuade workers to stop smoking. We performed a controlled intervention trial to evaluate the effectiveness of a new cessation program developed by Nakamura et al., which consisted of one brief individual counseling session and 4 follow-up telephone calls. Two hundred and twenty-eight smokers who visited our center for an annual health checkup were randomly divided into two group: 117 were assigned to the intervention group, and 111 were controls. Smoking status questionnaires were administered to assess the smoking habit of each subject and to evaluate their stages of change toward smoking cessation before the counseling session. Stage-matched cessation counseling was then provided to the intervention group by nurses who had completed training courses for this program. During the counseling session, carbon monoxide in expired air and nicotine metabolites in urine were measured to enhance self-perception of smoking. Only those clients who set a quit date during their counseling sessions received follow-up telephone calls. It was easy to implement this program (15 to 20 minutes long) during a health checkup. No significant differences were observed in the baseline characteristics of the two groups. The cross-sectional smoking cessation rates at 6 months and 1 year of follow-up were 6.2 times higher in the intervention group than in the control group. The continuous smoking cessation rate at 1 year of follow-up was 7.6 times higher in the intervention group than in the control group. In the intervention group, the lower level of nicotine metabolites in urine and higher smoking stage were related to cessation success, but other baseline characteristics were similar in those who quit smoking and those who did not. The effectiveness and easy applicability of this cessation program was proved in the present study. Further examinations in various settings are expected to clarify the effectiveness of this program. Smoking cessation of patients with cancer can improve treatment efficacy and survival.
                To determine whether a motivational interviewing intervention increased successful smoking cessation attempts of patients with cancer attending a South Australian public hospital, as compared with usual care.
                A randomized controlled trial was used to study 137 patients with mixed cancer sites, including 74 intervention patients and 63 control patients. The motivational interviewing intervention was delivered over a 3-month period. The intervention included a visit with a smoking cessation counselor, provision of smoking cessation booklets, nicotine replacement therapy, family advice to quit, and an in-person or telephone follow-up conversation.
                At the 6-month follow-up visit, an intention-to-treat analysis found no difference in biochemically confirmed 3-month prevalence quit rates between the intervention (5%) and control (6%) groups. A sensitivity analysis using more lenient criteria indicated quit rates of 29% for the intervention group and 18% for the control group (p = .32). The predictors of smoking cessation at 6 months for all the patients included a smoking-related cancer site, more cessation attempts in the year before enrollment in the study, and no radiation therapy.
                Future efforts to improve smoking cessation in this patient group might focus on the delivery of more direct methods for encouraging spouse cessation and support to the patient in quitting, and the use of bupropion (Zyban) as an adjunct to cessation for this heavy smoking patient group. Personalized feedback and a financial incentive, developed from an intrinsic/extrinsic motivation framework, were evaluated as adjuncts to self-help materials for smoking cessation. Ss (N = 1,217) were randomized to 4 treatment groups and were followed up at 3 and 12 months. Consistent with hypotheses derived from the motivation framework, the financial incentive increased the use of self-help materials, did not increase cessation rates among program users, and was associated with higher relapse rates among those who did manage to quit. The personalized feedback increased both smoking cessation and use of the materials 3 months after distribution of the materials. Continuous abstinence (abstinence at 3 and 12 months) in the group that received the personalized feedback alone was twice the rate of the other groups. To compare the effects of a worksite intervention by the occupational physician offering simple advice of smoking cessation with a more active strategy of advice including a "quit date" and extra support.
                Employees of an electrical and gas company seen at the annual visit by their occupational physicians. CRITERIA END POINTS: Smoking point prevalence defined as the percentage of smokers who were non-smokers at one year. Secondary criteria were the percentage of smokers who stopped smoking for more than six months and the difference in prevalence of smoking in both groups.
                Randomised controlled trial. The unit of randomisation was the work site physician and a random sample of the employees of whom he or she was in charge. The length of the follow up was one year. Each of 30 work site physicians included in the study 100 to 150 employees.
                Among 504 subjects classified as smokers at baseline receiving simple advice (group A) and 591 the more active programme (group B), 68 (13.5%) in group A and 109 (18. 4%) were non-smokers one year later (p=0.03; p=0.01 taking the occupational physician as the statistical unit and using a non-parametric test). Twenty three subjects (4.6%) in group A and 36 (6.1%) in group B (p=0.26) declared abstinence of six months or more. Among non-smokers at baseline, 3.4% in both groups were smokers after one year follow up. The prevalence of smokers did not differ significantly at baseline (32.9% and 32.4%, p=0.75). After the intervention the prevalence of smoking was 30.8% in group A and 28. 7% in group B (p=0.19). An increase of the mean symptoms score for depression in those who quit was observed during this period.
                A simple cessation intervention strategy during a mandatory annual examination, targeting a population of smokers independently of their motivation to stop smoking or their health status, showed a 36% relative increase of the proportion of smokers who quit smoking as compared with what can be achieved through simple advice. To determine the effectiveness of a systematic intensive tobacco counselling programme conducted by nursing professionals.
                Randomised clinical trial with control.
                Primary care nursing and medical consultations.
                Smokers requesting help in our centre's medical clinics during the recruitment period, up to the sample size required (125). Inclusion criteria were: aged between 18 and 70, people who smoked during the preceding month any number of cigarettes a day, and a score over 7 on the Richmond test.
                The patients recruited were randomised, according to the clinic from which they came, to the group that received brief counselling from the doctor (control group) or to the group that received brief counselling plus nursing follow-up (intervention group). Follow-up visits were programmed in this latter group for up to 3 months after giving up smoking.
                Abstinence at 12 and 24 months.
                The effectiveness of the intervention considered as the rate of abstinence at 12 months was 13.8% (95% CI, 6.5-24.7) in the control group and 6.7% (95% CI, 1.8-16.2) in the intervention group, with no significant differences between the two.
                In smokers seen in primary care, the effectiveness of a programme of intensive tobacco counselling by nursing staff is no more effective than the doctor's brief, one-off counselling. Brief counselling has a better cost-effectiveness relationship than intensive counselling.
1. We found strong evidence that interventions directed towards individual smokers increase the likelihood of quitting smoking. These include individual and group counselling and pharmacological treatment to overcome nicotine addiction. All these interventions show similar effects whether offered in the workplace or elsewhere. Self-help interventions and social support are less effective. Although people taking up these interventions are more likely to stop, the absolute numbers who quit are low.
2. There was limited evidence that participation in programmes can be increased by competitions and incentives organized by the employer.
3. We failed to detect an effect of comprehensive programmes in reducing the prevalence of smoking.
