This trial compared a brief group cognitive-behavioral (CBT) depression prevention program to a waitlist control condition and four placebo or alternative interventions. High-risk adolescents with elevated depressive symptoms (N=225, M age=18, 70% female) were randomized to CBT, supportive-expressive group intervention, bibliotherapy, expressive writing, journaling, or waitlist conditions and completed assessments at baseline, termination, and 1- and 6-month follow-up. All five active interventions showed significantly greater reductions in depressive symptoms at termination than waitlist controls; effects for CBT and bibliotherapy persisted into follow-up. CBT, supportive-expressive, and bibliotherapy participants also showed significantly greater decreases in depressive symptoms than expressive writing and journaling participants at certain follow-up points. Findings suggest there may be multiple ways to reduce depressive symptoms in high-risk adolescents, although expectancies, demand characteristics, and attention may have contributed to the observed effects. A cluster, stratified randomized design was used to evaluate the impact of universal, indicated, and combined universal plus indicated cognitive- behavioral approaches to the prevention of depression among 13- to 15-year-olds initially reporting elevated symptoms of depression. None of the intervention approaches differed significantly from a no-intervention condition or from each other on changes in depressive symptoms, anxiety, externalizing problems, coping skills, and social adjustment. All high-symptom students, irrespective of condition, showed a significant decline in depressive symptoms and improvement in emotional well-being over time although they still demonstrated elevated levels of psychopathology compared with the general population of peers at 12-month follow-up. There were also no significant intervention effects for the universal intervention in comparison with no intervention for the total sample of students in those conditions.

                A randomized, controlled trial was conducted to prevent depressive episodes in at-risk offspring (aged 13-18 years) of adults treated for depression in a health maintenance organization (HMO). Potential adult cases were found by reviewing the HMO pharmacy records for dispensation of antidepressant medication and the mental health appointment system. Medical charts were reviewed for a depression diagnosis. Recruitment letters signed by treating physicians were mailed to adults. Eligible offspring had subdiagnostic depressive symptoms insufficient to meet full DSM-III-R criteria for affective disorder and/or a past mood disorder. These youth were randomized to usual HMO care (n = 49) or usual care plus a 15-session group cognitive therapy prevention program (n = 45).
                We detected significant treatment-by-time (program) effects for the Center for Epidemiological Studies Depression Scale (P=.005) and the Global Assessment of Functioning scores (P =.04). Survival analysis of incident major depressive episodes during a median 15-month follow-up found a significant advantage (P =.003) for the experimental condition (9.3% cumulative major depression incidence) compared with the usual-care control condition (28.8%).
                A brief, group cognitive therapy prevention program can reduce the risk for depression in the adolescent offspring of parents with a history of depression. This investigation attempted to prevent unipolar depressive episodes in a sample of high school adolescents with an elevated risk of depressive disorder.
                Adolescents at risk for future depressive disorder by virtue of having elevated depressive symptomatology were selected with a two-stage case-finding procedure. The Center for Epidemiologic Studies-Depression Scale (CES-D) was administered to 1,652 students; adolescents with elevated CES-D scores were interviewed with the Schedule for Affective Disorders and Schizophrenia for School-Age Children. Subjects with current affective diagnoses were referred to nonexperimental services. The remaining 150 consenting subjects were considered at risk for future depression and randomized to either a 15-session cognitive group prevention intervention or an "usual care" control condition. Subjects were reassessed for DSM-III-R diagnostic status after the intervention and at 6- and 12-month follow-up points.
                Survival analyses indicated a significant 12-month advantage for the prevention program, with affective disorder total incidence rates of 14.5% for the active intervention, versus 25.7% for the control condition. No differences were detected for nonaffective disorders across the study period.
                Depressive disorder can be successfully prevented among adolescents with an elevated future risk. To conduct a placebo-controlled study of the effectiveness of a universal school-based depression prevention program.
                Three hundred ninety-two students age 13 to 15 from two schools were randomized to intervention (RAP-Kiwi) and placebo programs run by teachers. RAP-Kiwi was an 11-session manual-based program derived from cognitive-behavioral therapy. The placebo was similar but with cognitive components removed. Outcomes were self-rated depression scales, the Reynolds Adolescent Depression Scale (RADS), and the Beck Depression Inventory II (BDI-II). Follow-up was to 18 months. Analysis was done on an intent-to-treat basis.
                Immediately after the intervention, depression scores were reduced significantly more by RAP-Kiwi than by placebo, with a mean difference in change from baseline between groups of 1.5 on BDI-II (CI > 0.38, p =.01) and 2.24 on RADS (CI > 0.22, p =.04). Categorical analysis confirmed significant clinical benefit with an absolute risk reduction of 3% (95% CI, 1-11%, McNemar chi, p =.03), with the "number needed to treat" for short-term benefit of 33. Group differences in depression scores averaged across time to 18 months were significant on RADS but not on BDI-II. Retention rates were 91% at 6 months and 72% at 18 months.
                The RAP-Kiwi program is a potentially effective public health measure. Confirmation of effectiveness measuring episodes of depressive illness and broader measures of adjustment is warranted. Depressive disorders are experienced by 3-5% of the adolescent population at any point of time. They adversely affect adolescent development in a range of areas and greatly increase risk for suicide. The present study investigated the effectiveness of a universal intervention designed to reduce depressive symptoms among students commencing high school.
                Twenty-five pairs of secondary schools matched on socio-economic status were randomly assigned to either an intervention or a comparison group (n = 5,634 Year 8 students). The intervention extended over a 3-year period and utilised a comprehensive classroom curriculum programme, enhancements to the school climate, improvements in care pathways, and community forums. A range of measures completed by students, average age at baseline = 13.1 years (SD = .5), and teachers was used to assess changes in depressive symptoms, risk and protective factors relevant to depression, and the quality of the school environment.
                Changes in the level of depressive symptoms and in the levels of risk and protective factors experienced by students in the two groups did not differ significantly over the 3 years of the study. Furthermore, statistically significant differences in the ratings of school climate across this time period were found only for staff-rated assessments.
                Despite using an extensive, structured programme, based on best evidence to increase protective factors and reduce risk factors at the individual and school levels, the intervention did not reduce levels of depressive symptoms among participating adolescents. The results draw attention to the difficulties faced when implementing large-scale, school-based, universal preventive interventions. These include the need to develop methods to effectively train teachers across large geographical regions to deliver new interventions with fidelity, the difficulty of engaging young adolescents with prevention programmes, and the long period of time required to implement policy and practice changes at 'whole-school' levels. This study evaluated the efficacy of 2 programs for preventing depressive symptoms in adolescents. Participants were 380 high school students randomly assigned to a cognitive-behavioral program (CB), an interpersonal psychotherapy-adolescent skills training program (IPT-AST), or a no-intervention control. The interventions involved eight 90-min weekly sessions run in small groups during wellness classes. At postintervention, students in both the CB and IPT-AST groups reported significantly lower levels of depressive symptoms than did those in the no-intervention group, controlling for baseline depression scores; the 2 intervention groups did not differ significantly from each other. The effect sizes, using Cohen's d, for the CB intervention and the IPT-AST intervention were 0.37 and 0.26, respectively. Differences between control and intervention groups were largest for adolescents with high levels of depressive symptoms at baseline. For a high-risk subgroup, defined as having scored in the top 25th percentile on the baseline depression measure, the effect sizes for the CB and the IPT-AST interventions were 0.89 and 0.84, respectively. For the whole sample, sociotropy and achievement orientation moderated the effect of the interventions. Intervention effects were short term and were not maintained at 6-month follow-up.
                (PsycINFO Database Record (c) 2007 APA, all rights reserved). The aim in the current study was to investigate the effectiveness of an online, self-directed cognitive-behavioral therapy program (MoodGYM) in preventing and reducing the symptoms of anxiety and depression in an adolescent school-based population. A cluster randomized controlled trial was conducted with 30 schools (N = 1,477) from across Australia, with each school randomly allocated to the intervention or wait-list control condition. At postintervention and 6-month follow-up, participants in the intervention condition had significantly lower levels of anxiety than did participants in the wait-list control condition (Cohen's d = 0.15-0.25). The effects of the MoodGYM program on depressive symptoms were less strong, with only male participants in the intervention condition exhibiting significant reductions in depressive symptoms at postintervention and 6-month follow-up (Cohen's d = 0.27-0.43). Although small to moderate, the effects obtained in the current study provide support for the utility of universal prevention programs in schools. The effectiveness of booster sessions should be explored in future research. A randomized controlled trial was conducted to evaluate the efficacy of a cognitive-behavioral (CBT) intervention to prevent perinatal depression in high-risk Latinas.
                A sample of 217 participants, predominantly low-income Central American immigrants who met demographic and depression risk criteria, were randomized into usual care (UC; n = 105) or an 8-week CBT group intervention during pregnancy and 3 individual booster sessions during postpartum (n = 112). Participants completed measures assessing depressive symptoms (Center for Epidemiological Studies Depression Scale at baseline; Beck Depression Inventory, Second Edition [BDI-II]) and major depressive episodes (Mood Screener) at 5 time points throughout the perinatal period.
                Intent-to-treat analyses indicated that intervention participants had significantly lower depressive symptoms and fewer cases of moderate depression (BDI-II ≥ 20) at Time 2 than UC participants. These effects were stronger for women who fully participated in the intervention (≥ 4 classes). The cumulative incidence of major depressive episodes was not significantly different between the intervention (7.8%) and UC (9.6%) groups.
                A CBT intervention for low-income, high-risk Latinas reduced depressive symptoms during pregnancy but not during the postpartum period. Low levels of depressive symptoms and lower than expected rates of clinical depression in both groups may partially be due to methodological issues. As perinatal depression is a significant public health problem, more work is needed to prevent perinatal depression in low-income, ethnically diverse women.
                (c) 2011 APA, all rights reserved. A controlled trial was conducted to evaluate a prevention program aimed at reducing depressive and anxious symptoms in rural school children. Seventh-grade children with elevated depression were selected. Nine primary schools (n = 90) were randomly assigned to receive the program, and 9 control schools (n = 99) received their usual health education classes. Children completed questionnaires on depression, anxiety, explanatory style, and social skills. Parents completed the Child Behavior Checklist (T. M. Achenbach, 1991). No intervention effects were found for depression. Intervention group children reported less anxiety than the control group after the program and at 6-month follow-up and more optimistic explanations at postintervention. Intervention group parents reported fewer child internalizing and externalizing symptoms at postintervention only. Depression is the most common mental health disorder in people aged over 65 years. Late-life depression is associated with chronic illness and disability.
                To investigate the feasibility of a collaborative care model for depression in older people in a primary care setting.
                Randomised controlled trial with 16-weeks follow up.
                A primary care trust in Manchester.
                Participants were 105 people aged 60 years or older who scored 5 or more on the Geriatric Depression Scale; 53 were randomly allocated to an intervention group and 52 to a usual care group. The intervention group received care managed by a community psychiatric nurse who delivered an intervention comprising a facilitated self-help programme with close liaison with primary care professionals and old-age psychiatry according to a defined protocol. The usual care group received usual GP care. A nested qualitative study explored the views of the health professionals and patients regarding the acceptability and effectiveness of the intervention.
                The main outcome measure was recovery from depression. Patients in the intervention group were less likely to suffer from major depressive disorder at follow up compared with usual care (0.32, 95% confidence = interval = 0.11 to 0.93, P = 0.036). The qualitative component of the study demonstrated the acceptability of the intervention to patients.
                A model of collaborative care for older people with depression, used in a primary care setting with a facilitated self-help intervention is more effective than usual GP care. This study demonstrates that the implementation of a collaborative care model is feasible in UK primary care and that the intervention is effective and acceptable to patients. In this depression prevention trial, 341 high-risk adolescents (mean age = 15.6 years, SD = 1.2) with elevated depressive symptoms were randomized to a brief group cognitive-behavioral (CB) intervention, group supportive-expressive intervention, bibliotherapy, or assessment-only control condition. CB participants showed significantly greater reductions in depressive symptoms than did supportive-expressive, bibliotherapy, and assessment-only participants at posttest, though only the difference compared with assessment controls was significant at 6-month follow-up. CB participants showed significantly greater improvements in social adjustment and reductions in substance use at posttest and 6-month follow-up than did participants in all 3 other conditions. Supportive-expressive and bibliotherapy participants showed greater reductions in depressive symptoms than did assessment-only controls at certain follow-up assessments but produced no effects for social adjustment and substance use. CB, supportive-expressive, and bibliotherapy participants showed a significantly lower risk for major depression onset over the 6-month follow-up than did assessment-only controls. The evidence that this brief CB intervention reduced risk for future depression onset and outperformed alternative interventions for certain ecologically important outcomes suggests that this intervention may have clinical utility.
                Copyright 2008 APA, all rights reserved. Adolescent offspring of depressed parents are at markedly increased risk of developing depressive disorders. Although some smaller targeted prevention trials have found that depression risk can be reduced, these results have yet to be replicated and extended to large-scale, at-risk populations in different settings.
                To determine the effects of a group cognitive behavioral (CB) prevention program compared with usual care in preventing the onset of depression.
                A multicenter randomized controlled trial conducted in 4 US cities in which 316 adolescent (aged 13-17 years) offspring of parents with current or prior depressive disorders were recruited from August 2003 through February 2006. Adolescents had a past history of depression, current elevated but subdiagnostic depressive symptoms, or both. Assessments were conducted at baseline, after the 8-week intervention, and after the 6-month continuation phase.
                Adolescents were randomly assigned to the CB prevention program consisting of 8 weekly, 90-minute group sessions followed by 6 monthly continuation sessions or assigned to receive usual care alone.
                Rate and hazard ratio (HR) of a probable or definite depressive episode (ie, depressive symptom rating score of > or = 4) for at least 2 weeks as diagnosed by clinical interviewers.
                Through the postcontinuation session follow-up, the rate and HR of incident depressive episodes were lower for those in the CB prevention program than for those in usual care (21.4% vs 32.7%; HR, 0.63; 95% confidence interval [CI], 0.40-0.98). Adolescents in the CB prevention program also showed significantly greater improvement in self-reported depressive symptoms than those in usual care (coefficient, -1.1; z = -2.2; P = .03). Current parental depression at baseline moderated intervention effects (HR, 5.98; 95% CI, 2.29-15.58; P = .001). Among adolescents whose parents were not depressed at baseline, the CB prevention program was more effective in preventing onset of depression than usual care (11.7% vs 40.5%; HR, 0.24; 95% CI, 0.11-0.50), whereas for adolescents with a currently depressed parent, the CB prevention program was not more effective than usual care in preventing incident depression (31.2% vs 24.3%; HR, 1.43; 95% CI, 0.76-2.67).
                The CB prevention program had a significant prevention effect through the 9-month follow-up period based on both clinical diagnoses and self-reported depressive symptoms, but this effect was not evident for adolescents with a currently depressed parent.
                clinicaltrials.gov Identifier: NCT00073671. General practitioners (GPs) can be provided with effective training in the skills to manage depression. However, it remains uncertain whether such training achieves health gain for their patients.
                The study aimed to measure the health gain from training GPs in skills for the assessment and management of depression. The study design was a cluster randomized controlled trial. GP participants were assessed for recognition of psychological disorders, attitudes to depression, prescribing patterns and experience of psychiatry and communication skills training. They were then randomized to receive training at baseline or the end of the study. Patients selected by GPs were assessed at baseline, 3 and 12 months. The primary outcome was depression status, measured by HAM-D. Secondary outcomes were psychiatric symptoms (GHQ-12) quality of life (SF-36), satisfaction with consultations, and health service use and costs.
                Thirty-eight GPs were recruited and 36 (95%) completed the study. They selected 318 patients, of whom 189 (59%) were successfully recruited. At 3 months there were no significant differences between intervention and control patients on HAM-D, GHQ-12 or SF-36. At 12 months there was a positive training effect in two domains of the SF-36, but no differences in HAM-D, GHQ-12 or health care costs. Patients reported trained GPs as somewhat better at listening and understanding but not in the other aspects of satisfaction.
                Although training programmes may improve GPs' skills in managing depression, this does not appear to translate into health gain for depressed patients or the health service. Many patients with major depression are non-adherent to antidepressant medication and do not receive care according to current guidelines. There is increasing evidence that treatment of depression in primary care can be improved. Comparison between effective interventions may help to establish the active ingredients of such interventions.
                In a randomized trial two interventions to improve treatment of major depression in primary care were compared (1) a depression care programme, targeting general practitioners (GPs), patients, and systematic follow-up, and (2) a systematic follow-up programme. Thirty GPs were randomized and 211 primary-care patients with current major depression were included. All patients were prescribed a selective serotonin reuptake inhibitor. Outcome measures included adherence to antidepressant medication, and depression outcome.
                No significant differences in adherence rates and treatment outcome measures were demonstrated between interventions at week 10 or week 26. Adherence rates were high and treatment outcome was favourable.
                The depression care programme was not superior to the systematic follow-up programme. Systematic follow-up in depression treatment in primary care seems to be an intervention per se, having the potential to improve adherence and treatment outcome. Major depression is a frequent and serious disorder in older medical inpatients. Because the condition goes undetected and untreated in most of these patients, we conducted a randomized clinical trial to evaluate the effectiveness of a strategy of systematic detection and multidisciplinary treatment of depression in this population.
                Consecutive patients aged 65 years or more admitted to general medical services in a primary care hospital between October 1999 and November 2002 were screened for depression with the Diagnostic Interview Schedule (DIS) within 48 hours after admission. Patients found to have major depression were randomly allocated to receive the intervention or usual care. The intervention involved consultation and treatment by a psychiatrist and follow-up by a research nurse and the patient's family physician. Research assistants, blind to group allocation, collected data from the patients at enrollment and at 3 and 6 months later using the Hamilton Depression Rating Scale (HAMD), the Medical Outcomes 36-item Short Form (SF-36), the DIS, the Mini-Mental State Examination (MMSE), the Older Americans Resources and Services (OARS) questionnaire to assess basic and instrumental activities of daily living (OARS-ADL and OARS-IADL) and the Rating Scale for Side Effects. Data on the severity of illness, length of hospital stay, health services and medication use, mortality and process of care were also collected. The primary outcome measures were the HAMD and SF-36.
                Of 1500 eligible patients who were screened, 157 were found to have major depression and consented to participate (78 in the intervention group and 79 in the usual care group). At randomization, there were no clinically or statistically significant differences between the 2 groups. Sixty-four patients completed follow-up to 6 months, 57 withdrew, and 36 died. At 6 months, there were no clinically or statistically significant differences the 2 groups in HAMD or SF-36 scores or any of the secondary outcome measures.
                We were unable to demonstrate that systematic detection and multidisciplinary care of depression was more beneficial than usual care for elderly medical inpatients. Depression and anxiety disorders are common mental disorders worldwide. The MANAS trial aimed to test the effectiveness of an intervention led by lay health counsellors in primary care settings to improve outcomes of people with these disorders.
                In this cluster randomised trial, primary care facilities in Goa, India, were assigned (1:1) by computer-generated randomised sequence to intervention or control (enhanced usual care) groups. All adults who screened positive for common mental disorders were eligible. The collaborative stepped-care intervention offered case management and psychosocial interventions, provided by a trained lay health counsellor, supplemented by antidepressant drugs by the primary care physician and supervision by a mental health specialist. The research assessor was masked. The primary outcome was recovery from common mental disorders as defined by the International Statistical Classification of Diseases and Related Health Problems-10th revision (ICD-10) at 6 months. This study is registered with ClinicalTrials.gov, number NCT00446407.
                24 study clusters, with an equal proportion of public and private facilities, were randomised equally between groups. 1160 of 1360 (85%) patients in the intervention group and 1269 of 1436 (88%) in the control group completed the outcome assessment. Patients with ICD-10-confirmed common mental disorders in the intervention group were more likely to have recovered at 6 months than were those in the control group (n=620 [65·0%] vs 553 [52·9%]; risk ratio 1·22, 95% CI 1·00-1·47; risk difference=12·1%, 95% CI 1·6%-22·5%). The intervention had strong evidence of an effect in public facility attenders (369 [65·9%] vs 267 [42·5%], risk ratio 1·55, 95% CI 1·02-2·35) but no evidence for an effect in private facility attenders (251 [64·1%] vs 286 [65·9%], risk ratio 0·95, 0·74-1·22). There were three deaths and four suicide attempts in the collaborative stepped-care group and six deaths and six suicide attempts in the enhanced usual care group. None of the deaths were from suicide.
                A trained lay counsellor-led collaborative care intervention can lead to an improvement in recovery from CMD among patients attending public primary care facilities.

A family cognitive-behavioral preventive intervention for parents with a history of depression and their 9-15-year-old children was compared with a self-study written information condition in a randomized clinical trial (n = 111 families). Outcomes were assessed at postintervention (2 months), after completion of 4 monthly booster sessions (6 months), and at 12-month follow-up. Children were assessed by child reports on depressive symptoms, internalizing problems, and externalizing problems; by parent reports on internalizing and externalizing problems; and by child and parent reports on a standardized diagnostic interview. Parent depressive symptoms and parent episodes of major depression also were assessed. Evidence emerged for significant differences favoring the family group intervention on both child and parent outcomes; strongest effects for child outcomes were found at the 12-month assessment with medium effect sizes on most measures. Implications for the prevention of adverse outcomes in children of depressed parents are highlighted. This research study evaluates the effectiveness of a multifaceted intervention program to improve the management of depression in primary care.
                One hundred fifty-three primary care patients with current depression were entered into a randomized controlled trial. Intervention patients received a structured depression treatment program in the primary care setting that included both behavioral treatment to increase use of adaptive coping strategies and counseling to improve medication adherence. Control patients received "usual" care by their primary care physicians. Outcome measures included adherence to antidepressant medication, satisfaction with care of depression and with antidepressant treatment, and reduction of depressive symptoms over time.
                At 4-month follow-up, significantly more intervention patients with major and minor depression than usual care patients adhered to antidepressant medication and rated the quality of care they received for depression as good to excellent. Intervention patients with major depression demonstrated a significantly greater decrease in depression severity over time compared with usual care patients on all 4 outcome analyses. Intervention patients with minor depression were found to have a significant decrease over time in depression severity on only 1 of 4 study outcome analyses compared with usual care patients.
                A multifaceted primary care intervention improved adherence to antidepressant regimens and satisfaction with care in patients with major and minor depression. The intervention consistently resulted in more favorable depression outcomes among patients with major depression, while outcome effects were ambiguous among patients with minor depression. Major depression and dysthymia are frequent, debilitating, and chronic disorders, whose highest rate of initial onset is during the late adolescent years. The effectiveness of a program designed to prevent an initial episode of major depression or dysthymia among adolescents was investigated. Participants were 171 fourteen-year-old "at risk" Icelandic adolescents who were randomly assigned to a prevention program or a treatment-as-usual assessment only control group. They were identified as "at risk" by reporting the presence of depressive symptoms or a negative attributional style. The program was based on a developmental psychosocial model of enhancement of resilience to factors associated with the occurrence of mood disorders. The results indicated that the prevention program resulted in a significantly lower rate of major depression and dysthymia than did the control group. The study demonstrated that school personnel in the school setting can implement such prevention programs. Depression, a common disorder often treated by family physicians, may be both underdiagnosed and undertreated. The objective of this study was to determine whether the diagnosis and treatment of depression by family physicians could be improved through an educational strategy.
                In this study, conducted between July and December 1997, 42 family physicians in Newfoundland were randomly assigned to an intervention group (3-hour case-based educational session on clinical practice guidelines [CPGs] for depression and access to a psychiatrist for consultation) or to a control group (receipt of CPGs without educational session or access to the psychiatrist). Physicians were asked to keep a log of patients with newly diagnosed depression and to record information on severity of depression, medications and referrals to mental health professionals. Patients were asked to complete the Centre for Epidemiologic Studies Depression (CES-D) scale before treatment and after 6 months of follow-up. The primary outcome measure was the "gain" score (difference between first and last CES-D scores).
                During the study period physicians in the intervention group diagnosed 91 new cases of depression (mean 4.1 per physician) and those in the control group diagnosed 56 (mean 2.8 per physician); the difference was not significant. Most patients (91.2% in the intervention group and 89.3% in the control group received a prescription for an antidepressant on their first visit. Similar proportions (46.2% in the intervention group and 37.5% in the control group) took their medication for the full 6 months; however, significantly more patients in the intervention group were taking an antidepressant at the 6-month follow-up (56% v. 39.3%, p = 0.02). The mean number of visits per patient was similar in the 2 groups (7.7 in the intervention group and 7.6 in the control group). Physicians in the intervention group consulted the psychiatrist 9 times. The overall rate of referrals to psychiatrists and other mental health professionals was 10.9%; however, referrals were significantly higher in the intervention group (15.4% v. 3.5%, p = 0.05). After 6 months of follow-up, a significant difference in gain scores was detected between the intervention and control groups for both the patient's self-rated CES-D scores (mean gain score 19.3 v. 15.5 respectively, p = 0.04) and the physicians' ratings of depression severity before treatment and at 6 months (mean gain 1.1 v. 0.7 respectively, p = 0.02).
                The educational strategy had a modest beneficial effect on the outcomes of patients with depression, but there are still concerns regarding the low rates of drug treatment and referral to mental health professionals by family physicians. Various methods are available for implementing change in the clinical behaviour of general practitioners (GPs). Although passive dissemination of information is generally ineffective, other methods can be variably effective. Few studies have investigated the impact of tailored methods.
                To determine whether methods tailored to overcome obstacles to change using psychological theories are more effective than dissemination alone in the implementation of guidelines for depression among GPs.
                Randomised controlled trial.
                Sixty general practices in England; 30 GPs in the control group, 34 in the intervention group.
                Practitioners identified patients presenting with depression before and after the implementation of guidelines (control group n = 192 in the first data collection, n = 181 in the second; intervention group n = 210 in the first data collection and n = 197 in the second). The main outcome measures were: record of adherence to guideline recommendations in clinical records; proportion of patients with Beck Depression Inventory (BDI) score less than 11 at 16 weeks after diagnosis.
                In comparison with the control group, in the group of GPs receiving tailored implementation, there were increases in the proportions of patients assessed for suicide risk. In the intervention group, the proportion of patients with BDI scores of less than 11 at 16 weeks increased.
                Obstacles to implementation can be identified and strategies tailored to address them. The findings indicate a new approach for research to understand and develop methods of implementation. Social support theory and observational risk factor studies suggest that increased antenatal psychosocial support could prevent post-natal depression. We used empirical knowledge of risk and protective factors for post-natal depression not employed previously in order to develop and evaluate an antenatal preventive intervention.
                We conducted a pragmatic randomized controlled trial in antenatal clinics. We screened 1300 primiparous women and 400 screened positive, 69 screen-positive women were untraceable or not eligible. Of 292 women who completed baseline assessment, 209 consented to randomization, of these 190 provided outcome data 3 months post-natally. 'Preparing for Parenthood', a structured antenatal risk factor reducing intervention designed to increase social support and problem-solving skills, was compared with routine antenatal care only. We compared the percentage depressed at 3 months after childbirth using the self-completion General Health Questionnaire Depression scale and Edinburgh Post-natal Depression Scale (EPDS), and the Schedules for Clinical Assessment in Neuropsychiatry a systematic clinical interview.
                Assignment to the intervention group did not significantly impact on post-natal depression (odds ratio for GHQ-Depression 1.22 (95% CI 0.63-2.39), P = 0.55) or on risk factors for depression. Forty-five per cent of the intervention group women attended sufficient sessions to be likely to benefit from intervention if effective. Attenders benefited no more than non-attenders.
                Prevention services targeting post-natal depression should not implement antenatal support programmes on these lines until further research has demonstrated the feasibility and effectiveness of such methods. The development of novel, low cost interventions effective in reducing risk factors should be completed before further trial evaluation. Despite high rates of relapse and recurrence, few primary care patients with recurrent or chronic depression are receiving continuation and maintenance-phase treatment. We hypothesized that a relapse prevention intervention would improve adherence to antidepressant medication and improve depression outcomes in high-risk patients compared with usual primary care.
                Three hundred eighty-six patients with recurrent major depression or dysthymia who had largely recovered after 8 weeks of antidepressant treatment by their primary care physicians were randomized to a relapse prevention program (n = 194) or usual primary care (n = 192). Patients in the intervention group received 2 primary care visits with a depression specialist and 3 telephone visits over a 1-year period aimed at enhancing adherence to antidepressant medication, recognition of prodromal symptoms, monitoring of symptoms, and development of a written relapse prevention plan. Follow-up assessments were completed at 3, 6, 9, and 12 months by a telephone survey team blinded to randomization status.
                Those in the intervention group had significantly greater adherence to adequate dosage of antidepressant medication for 90 days or more within the first and second 6-month periods and were significantly more likely to refill medication prescriptions during the 12-month follow-up compared with usual care controls. Intervention patients had significantly fewer depressive symptoms, but not fewer episodes of relapse/recurrence over the 12-month follow-up period.
                A relapse prevention program targeted to primary care patients with a high risk of relapse/recurrence who had largely recovered after antidepressant treatment significantly improved antidepressant adherence and depressive symptom outcomes. The majority of randomised controlled trials examining the effectiveness of antenatal group interventions at preventing postnatal depression in "at risk" women have used a "psychoeducational" intervention. The aim of the present study is to evaluate the effectiveness of an antenatal cognitive behavioural group intervention in a primary care setting for pregnant women identified with mild to moderate symptoms in pregnancy and/or at risk of developing depression or anxiety in the perinatal period.
                Subjects were randomised to a CBT group intervention or control condition (information booklet) and administered the EPDS and STAI at pre (Time 1) and post intervention (Time 2), and at 2 months (Time 3) and 4 months postpartum (Time 4). MINIs were administered at Times 1, 3 and 4.
                Of the 774 women approached, 277 accepted and were suitable; thus 191 were randomised to the CBT intervention and 86 to the control condition. The subsequent 52% drop-out left 89 women "completing" the CBT groups and 43 in the control group; these two groups were well matched on demographic variables. Intention to treat analyses revealed relatively low mean baseline EPDS scores (means 6.88 -8.16) with no reduction in EPDS scores in either group from Time 1 to Time 4. MINI depression criteria were fulfilled by 19% of all participants at Time 1 but there was no reduction in depression in either group; in contrast those with MINI anxiety diagnoses reduced from 28% in late pregnancy to 16% at four months postpartum in the CBT group with similar reductions in the control group. Analyses on the 132 "completers" showed significant symptomatic improvement over time for both the CBT group and control condition. Depression scores in the most symptomatic women (EPDS>12; N=19) decreased steadily by over 50% over the total time course but there were no differences in improvement between the CBT and control groups.
                A number of methodological factors may have obscured our results including a tendency to natural remission in mildly symptomatic subjects and the possibility that our control condition was therapeutic in itself.
                While a modest reduction in depression scores was noted in study "completers", both the CBT group intervention control condition were equally beneficial. The reasons for this finding include the low symptom level at baseline; the potential effectiveness of the control condition; and the brevity of the intervention. To compare the effectiveness of a multifaceted intervention in patients with depression in primary care with the effectiveness of "usual care" by the primary care physician.
                A randomized controlled trial among primary care patients with major depression or minor depression.
                Over a 12-month period a total of 217 primary care patients who were recognized as depressed by their primary care physicians and were willing to take antidepressant medication were randomized, with 91 patients meeting criteria for major depression and 126 for minor depression.
                Intervention patients received increased intensity and frequency of visits over the first 4 to 6 weeks of treatment (visits 1 and 3 with a primary care physician, visits 2 and 4 with a psychiatrist) and continued surveillance of adherence to medication regimens during the continuation and maintenance phases of treatment. Patient education in these visits was supplemented by videotaped and written materials.
                Primary outcome measures included short-term (30-day) and long-term (90-day) use of antidepressant medication at guideline dosage levels, satisfaction with overall care for depression and antidepressant medication, and reduction in depressive symptoms.
                In patients with major depression, the intervention group had greater adherence than the usual care controls to adequate dosage of antidepressant medication for 90 days or more (75.5% vs 50.0%; P < .01), were more likely to rate the quality of the care they received for depression as good to excellent (93.0% vs 75.0%; P < .03), and were more likely to rate antidepressant medications as helping somewhat to helping a great deal (88.1% vs 63.3%; P < .01). Seventy-four percent of intervention patients with major depression showed 50% or more improvement on the Symptom Checklist-90 Depressive Symptom Scale compared with 43.8% of controls (P < .01), and the intervention patients also demonstrated a significantly greater decrease in depression severity over time compared with controls (P < .004). In patients with minor depression, the intervention group had significantly greater adherence than controls to adequate dosage of antidepressant medication for 90 days or more (79.7% vs 40.3%; P < .001) and more often rated antidepressant medication as helping somewhat to helping a great deal (81.8% vs 61.4%; P < .02). However, no significant differences were found between the intervention and control groups in the percentage of patients who were satisfied with the care they received for depression (94.4% vs 89.3%), in the percentage who experienced a 50% or more decrease in depressive symptoms, or in the decrease of depressive symptoms over time.
                A multifaceted intervention consisting of collaborative management by the primary care physician and a consulting psychiatrist, intensive patient education, and surveillance of continued refills of antidepressant medication improved adherence to antidepressant regimens in patients with major and with minor depression. It improved satisfaction with care and resulted in more favorable depressive outcomes in patients with major, but not minor, depression. The authors investigated the effectiveness and specificity of the Penn Resiliency Program (PRP; J. E. Gillham, L. H. Jaycox, K. J. Reivich, M. E. P. Seligman, & T. Silver, 1990), a cognitive-behavioral depression prevention program. Children (N = 697) from 3 middle schools were randomly assigned to PRP, Control (CON), or the Penn Enhancement Program (PEP; K. J. Reivich, 1996; A. J. Shatté, 1997), an alternate intervention that controls for nonspecific intervention ingredients. Children's depressive symptoms were assessed through 3 years of follow-up. There was no intervention effect on average levels of depressive symptoms in the full sample. Findings varied by school. In 2 schools, PRP significantly reduced depressive symptoms across the follow-up relative to both CON and PEP. In the 3rd school, PRP did not prevent depressive symptoms. The authors discuss the findings in relation to previous research on PRP and the dissemination of prevention programs.

Those who were labelled as depressives in a rural survey were randomly divided into a Medicine group (who received antidepressive drug treatment), a Placebo group (who received placebo) and a Natural Process group (who received no treatment). The depth of their depression was assessed by Hamilton's Depressive Rating Scale before the beginning of the trial, on the 14th day and on the 28th day of trial. They were compared with a matched group of healthy controls and again with a matched group of depressives who attended an urban clinic for treatment. The results indicate that the rural depressives who never sought treatment voluntarily were not different from those who sought treatment in clinics, so far as their response to treatment is concerned. The aim of this study was to determine both the clinical and cost-effectiveness of usual general practitioner (GP) care compared with two types of brief psychological therapy (non-directive counselling and cognitive-behaviour therapy) in the management of depression as well as mixed anxiety and depression in the primary care setting.
                The design was principally a pragmatic randomised controlled trial, but was accompanied by two additional allocation methods allowing patient preference: the option of a specific choice of treatment (preference allocation) and the option to be randomised between the psychological therapies only. Of the 464 patients allocated to the three treatments, 197 were randomised between the three treatments, 137 chose a specific treatment, and 130 were randomised between the psychological therapies only. The patients underwent follow-up assessments at 4 and 12 months.
                The study was conducted in 24 general practices in Greater Manchester and London.
                A total of 464 eligible patients, aged 18 years and over, were referred by 73 GPs and allocated to one of the psychological therapies or usual GP care for depressive symptoms.
                The interventions consisted of brief psychological therapy (12 sessions maximum) or usual GP care. Non-directive counselling was provided by counsellors who were qualified for accreditation by the British Association for Counselling. Cognitive-behaviour therapy was provided by clinical psychologists who were qualified for accreditation by the British Association for Behavioural and Cognitive Psychotherapies. Usual GP care included discussions with patients and the prescription of medication, but GPs were asked to refrain from referring patients for psychological intervention for at least 4 months. Most therapy sessions took place on a weekly basis in the general practices. By the 12-month follow-up, GP care in some cases did include referral to mental healthcare specialists.
                The clinical outcomes included depressive symptoms, general psychiatric symptoms, social function and patient satisfaction. The economic outcomes included direct and indirect costs and quality of life. Assessments were carried out at baseline during face-to-face interviews as well as at 4 and 12 months in person or by post.
                At 4 months, both psychological therapies had reduced depressive symptoms to a significantly greater extent than usual GP care. Patients in the psychological therapy groups exhibited mean scores on the Beck Depression Inventory that were 4-5 points lower than the mean score of patients in the usual GP care group, a difference that was also clinically significant. These differences did not generalize to other measures of outcome. There was no significant difference in outcome between the two psychological therapies when they were compared directly using all 260 patients randomised to a psychological therapy by either randomised allocation method. At 12 months, the patients in all three groups had improved to the same extent. The lack of a significant difference between the treatment groups at this point resulted from greater improvement of the patients in the GP care group between the 4- and 12-month follow-ups. At 4 months, patients in both psychological therapy groups were more satisfied with their treatment than those in the usual GP care group. However, by 12 months, patients who had received non-directive counselling were more satisfied than those in either of the other two groups. There were few differences in the baseline characteristics of patients who were randomised or expressed a treatment preference, and no differences in outcome between these patients. Similar outcomes were found for patients who chose either psychological therapy. Again, there were no significant differences between the two groups at 4 or 12 months. Patients who chose counselling were more satisfied with treatment than those who chose c Major depressive disorder severely impairs the quality of life of patients with medical disorders such as cancer, but evidence to guide its management is scarce. We aimed to assess the efficacy and cost of a nurse-delivered complex intervention that was designed to treat major depressive disorder in patients who have cancer.
                We did a randomised trial in a regional cancer centre in Scotland, UK. 200 outpatients who had cancer with a prognosis of greater than 6 months and major depressive disorder (identified by screening) were eligible and agreed to take part. Their mean age was 56.6 (SD 11.9) years, and 141 (71%) were women. We randomly assigned 99 of these participants to usual care, and 101 to usual care plus the intervention, with minimisation for sex, age, diagnosis, and extent of disease. The intervention was delivered by a cancer nurse at the centre over an average of seven sessions. The primary outcome was the difference in mean score on the self-reported Symptom Checklist-20 depression scale (range 0 to 4) at 3 months after randomisation. Analysis was by intention to treat. This trial is registered as ISRCTN84767225.
                Primary outcome data were missing for four patients. For 196 patients for whom we had data at 3 months, the adjusted difference in mean Symptom Checklist-20 depression score, between those who received the intervention and those who did not, was 0.34 (95% CI 0.13-0.55). This treatment effect was sustained at 6 and 12 months. The intervention also improved anxiety and fatigue but not pain or physical functioning. It cost an additional pound sterling 5278 (US$10 556) per quality-adjusted life-year gained.
                The intervention-Depression Care for People with Cancer-offers a model for the management of major depressive disorder in patients with cancer and other medical disorders who are attending specialist medical services that is feasible, acceptable, and potentially cost effective. Promising results were obtained in an earlier pilot study of a preventive intervention based on the principles of interpersonal psychotherapy to reduce the risk of postpartum major depressive disorder. In this study, the authors examined whether the intervention would reduce the risk of postpartum major depressive disorder in a larger sample of pregnant women.
                Ninety-nine pregnant women on public assistance who were assessed to be at risk for postpartum depression were randomly assigned to receive standard antenatal care plus the intervention or standard antenatal care only. Diagnostic interviews were administered 3 months after delivery to assess for major depressive disorder.
                Within 3 months after delivery, eight (20%) of the women in the standard antenatal care condition had developed postpartum major depressive disorder, compared with two (4%) in the intervention condition.
                This study provides further evidence for the efficacy of a brief intervention to reduce the occurrence of major depressive disorder among financially disadvantaged women during a postpartum period of 3 months. Few depressed older adults receive effective treatment in primary care settings.
                To determine the effectiveness of the Improving Mood-Promoting Access to Collaborative Treatment (IMPACT) collaborative care management program for late-life depression.
                Randomized controlled trial with recruitment from July 1999 to August 2001.
                Eighteen primary care clinics from 8 health care organizations in 5 states.
                A total of 1801 patients aged 60 years or older with major depression (17%), dysthymic disorder (30%), or both (53%).
                Patients were randomly assigned to the IMPACT intervention (n = 906) or to usual care (n = 895). Intervention patients had access for up to 12 months to a depression care manager who was supervised by a psychiatrist and a primary care expert and who offered education, care management, and support of antidepressant management by the patient's primary care physician or a brief psychotherapy for depression, Problem Solving Treatment in Primary Care.
                Assessments at baseline and at 3, 6, and 12 months for depression, depression treatments, satisfaction with care, functional impairment, and quality of life.
                At 12 months, 45% of intervention patients had a 50% or greater reduction in depressive symptoms from baseline compared with 19% of usual care participants (odds ratio [OR], 3.45; 95% confidence interval [CI], 2.71-4.38; P<.001). Intervention patients also experienced greater rates of depression treatment (OR, 2.98; 95% CI, 2.34-3.79; P<.001), more satisfaction with depression care (OR, 3.38; 95% CI, 2.66-4.30; P<.001), lower depression severity (range, 0-4; between-group difference, -0.4; 95% CI, -0.46 to -0.33; P<.001), less functional impairment (range, 0-10; between-group difference, -0.91; 95% CI, -1.19 to -0.64; P<.001), and greater quality of life (range, 0-10; between-group difference, 0.56; 95% CI, 0.32-0.79; P<.001) than participants assigned to the usual care group.
                The IMPACT collaborative care model appears to be feasible and significantly more effective than usual care for depression in a wide range of primary care practices. To standardise the delivery of a brief group cognitive behaviour therapy intervention (CBT-G). To apply the intervention in a research setting and to estimate its effect on recurrence rates in recently depressed older adults, in preparation for a definitive study.
                A CBT-G therapy manual was produced and the Cognitive Therapy Rating Scale (CTS-R) modified to assess therapy delivery. Forty-five adults aged 60 and over who had met ICD-10 criteria for major depression in the previous year and were still taking antidepressant medication were randomly allocated to CBT-G/antidepressant combination or antidepressant alone. Depression severity was measured at baseline, randomisation and 6 and 12 months after start of CBT-G using the Montgomery Asberg Rating Scale for Depression (MADRS).
                One-year recurrence rates on the MADRS were encouragingly lower in participants receiving CBT-G [5/18 (27.8%)] compared with controls [8/18 (44.4%)] although this did not achieve statistical significance (adjusted RR 0.70 [95% CI 0.26-1.94]). In contrast, overall scores on the secondary outcome measure, the Beck Depression Inventory, increased in participants receiving CBT-G. The CBT-G manual was successfully implemented and therapy delivery achieved an overall satisfactory level of competence. We believe that evaluation of this promising intervention in a full-scale trial is warranted.
                (c) 2008 John Wiley & Sons, Ltd. Depression is a disabling, prevalent condition. Physical activity programs may assist depression management in older people, ameliorate co-morbid conditions and reduce the need for antidepressants. The UPLIFT pilot study assessed the feasibility of older depressed people attending a community-based progressive resistance training (PRT) program. The study also aimed to determine whether PRT improves depressive status in older depressed patients.
                A randomised controlled trial was conducted. People aged > or = 65 years with depressive symptoms were recruited via general practices. Following baseline assessment, subjects were randomly allocated to attend a local PRT program three times per week for 10 weeks or a brief advice control group. Follow-up assessment of depressive status, physical and psychological health, functional and quality of life status occurred post intervention and at six months.
                Three hundred and forty six people responded to the study invitation, of whom 22% had depressive symptoms (Geriatric Depression Scale, GDS-30 score > or = 11). Thirty two people entered the trial. There were no significant group differences on the GDS at follow-up. At six months there was a trend for the PRT intervention group to have lower GDS scores than the comparison group, but this finding did not reach significance (p = 0.08). More of the PRT group (57%) had a reduction in depressive symptoms post program, compared to 44% of the control group. It was not possible to discern which specific components of the program influenced its impact, but in post hoc analyses, improvement in depressive status appeared to be associated with the number of exercise sessions completed (r = -0.8, p < 0.01).
                The UPLIFT pilot study confirmed that older people with depression can be successfully recruited to a community based PRT program. The program can be offered by existing community-based facilities, enabling its ongoing implementation for the potential benefit of other older people. There is a high prevalence of depression in patients with diabetes mellitus. Depression has been shown to be associated with poor self-management (adherence to diet, exercise, checking blood glucose levels) and high hemoglobin A1c (HbA1c) levels in patients with diabetes.
                To determine whether enhancing quality of care for depression improves both depression and diabetes outcomes in patients with depression and diabetes.
                Randomized controlled trial with recruitment from March 1, 2001, to May 31, 2002.
                Nine primary care clinics from a large health maintenance organization.
                A total of 329 patients with diabetes mellitus and comorbid major depression and/or dysthymia. Intervention Patients were randomly assigned to the Pathways case management intervention (n = 164) or usual care (n = 165). The intervention provided enhanced education and support of antidepressant medication treatment prescribed by the primary care physician or problem-solving therapy delivered in primary care.
                Independent blinded assessments at baseline and 3, 6, and 12 months of depression (Hopkins Symptom Checklist 90), global improvement, and satisfaction with care. Automated clinical data were used to evaluate adherence to antidepressant regimens, percentage receiving specialty mental health visits, and HbA1c levels.
                When compared with usual care patients, intervention patients showed greater improvement in adequacy of dosage of antidepressant medication treatment in the first 6-month period (odds ratio [OR], 4.15; 95% confidence interval [CI], 2.28-7.55) and the second 6-month period (OR, 2.90; 95% CI, 1.69-4.98), less depression severity over time (z = 2.84, P = .004), a higher rating of patient-rated global improvement at 6 months (intervention 69.4% vs usual care 39.3%; OR, 3.50; 95% CI, 2.16-5.68) and 12 months (intervention 71.9% vs usual care 42.3%; OR, 3.50; 95% CI, 2.14-5.72), and higher satisfaction with care at 6 months (OR, 2.01; 95% CI, 1.18-3.43) and 12 months (OR, 2.88; 95% CI, 1.67-4.97). Although depressive outcomes were improved, no differences in HbA1c outcomes were observed.
                The Pathways collaborative care model improved depression care and outcomes in patients with comorbid major depression and/or dysthymia and diabetes mellitus, but improved depression care alone did not result in improved glycemic control. To evaluate a program designed to help high school students with depressive symptomology to effectively cope.
                Two-phase experimental study.
                Rural high school students (N = 222), ages 14 through 19 years, were surveyed to identify teens with depressive symptomatology, identify stressful life events and coping styles of at-risk subjects, and evaluate a cognitive-behavioral group intervention to enhance students' coping and affect levels of depression. Students with depressive symptomatology were randomized into control (n = 18) or intervention (n = 23) groups. Intervention subjects were treated with a nurse-led, 8-week cognitive skills group, conducted at school.
                On posttesting, the intervention groups demonstrated reduced depressive symptoms in females and a wider range of coping compared with controls.
                School-based nurses are in an ideal position to provide assessment, referral, and intervention programs in the natural setting of the school. Results of this study indicate that such programs can be implemented successfully in schools and have the potential to promote mental health in teenagers.
There is some evidence from this review that targeted and universal depression prevention programmes may prevent the onset of depressive disorders compared with no intervention. However, allocation concealment is unclear in most studies, and there is heterogeneity in the findings. The persistence of findings suggests that this is real and not a placebo effect.
