Treatments for chronic anxiety have received considerable interest recently. Firstly, there is a body of research which has shown problems of dependence and habituation in the long-term use of anti-anxiety drugs. A second development is that of psychological treatments for anxiety. Because of the problems involved in the use of benzodiazepines, it is important to determine whether or not psychological treatments are a reasonable alternative when treating chronic anxiety. This study was designed to test the relative effectiveness of cognitive-behavioural therapy, anxiety management training and treatment by benzodiazepines against a waiting list control. Measures were taken on both the process and outcome of treatment. The most immediate and greatest improvements in anxiety were seen in the group receiving drugs. However, these improvements reduced as the trial progressed and were minimal at the end of therapy. Both psychological treatment groups improved as the trial progressed with the most significant and consistent changes seen in the cognitive-behaviour therapy group. However, at follow-up there was no difference between the two groups receiving psychological treatments. Because of their lack of sustained improvement, over half of the group receiving drugs refused to wait without treatment until the follow-up assessment. Effectiveness studies have tested interventions to improve quality of care for depression in primary care, but none, to our knowledge, have been completed for panic disorder (PD) in this setting. This study sought to test the clinical effectiveness of PD pharmacotherapy embedded in a disease management framework of "collaborative care" (CC).
                One hundred fifteen patients with PD from 3 primary care clinics were randomized to CC or "usual care" (UC). Patients in CC (n = 57) received educational videotapes and pamphlets; pharmacotherapy with the selective serotonin reuptake inhibitor paroxetine; 2 psychiatrist visits and 2 telephone calls in the first 8 weeks; and up to 5 telephone calls between 3 and 12 months' follow-up. Usual care patients (n = 58) were treated by their primary care physician. Telephone assessments of panic, anxiety sensitivity, depression, and disability variables were performed at 3, 6, 9, and 12 months' follow-up. Adequacy of pharmacotherapy was assessed with an algorithm based on a review of efficacy studies.
                Patients in CC were more likely to receive adequate (type, dose, duration) medication and more likely to adhere to this medication at 3 and 6 months. Random regression analyses showed that CC patients improved significantly more over time compared with UC patients on anxiety, depression, and disability measures, with the greatest effects at 3 and 6 months.
                Compared with UC, CC interventions significantly improved both quality of care and clinical and functional outcomes in primary care PD patients. Clinical differences were greatest in the first 6 months, corresponding to the greater quality of care and the greater intensity of intervention. Panic disorder is a prevalent, often disabling condition among patients in the primary care setting. Although numerous studies have assessed the effectiveness of treatments for depression in primary care, few such studies have been conducted for panic disorder.
                To implement and test the effectiveness of a combined pharmacotherapy and cognitive-behavioral intervention for panic disorder tailored to the primary care setting.
                Randomized, controlled study comparing intervention to treatment as usual.
                Six primary care clinics associated with 3 university medical schools, serving an ethnically and socioeconomically diverse patient population.
                Two hundred thirty-two primary care patients meeting DSM-IV criteria for panic disorder. Comorbid mental and physical disorders were permitted, provided these did not contraindicate the treatment to be provided and were not acutely life threatening.
                Patients were randomized to receive either treatment as usual or an intervention consisting of a combination of up to 6 sessions (across 12 weeks) of cognitive-behavioral therapy (CBT) modified for the primary care setting, with up to 6 follow-up telephone contacts during the next 9 months, and algorithm-based pharmacotherapy provided by the primary care physician with guidance from a psychiatrist. Behavioral health specialists, the majority inexperienced in CBT for panic disorder, were trained to deliver the CBT and coordinated overall care, including pharmacotherapy.
                Proportion of subjects remitted (no panic attacks in the past month, minimal anticipatory anxiety, and agoraphobia subscale score <10 on Fear Questionnaire) and responding (Anxiety Sensitivity Index score <20) and change over time in World Health Organization Disability Scale and short form 12 scores.
                The combined cognitive-behavioral and pharmacotherapeutic intervention resulted in sustained and gradually increasing improvement relative to treatment as usual, with significantly higher rates at all points of both the proportion of subjects remitted (3 months, 20% vs 12%; 12 months, 29% vs 16%) and responding (3 months, 46% vs 27%; 12 months, 63% vs 38%) and significantly greater improvements in World Health Organization Disability Scale (all points) and short form 12 mental health functioning (3 and 6 months) scores. These effects were obtained in spite of similar rates of delivery of guideline-concordant pharmacotherapy to the 2 groups.
                Delivery of evidence-based CBT and medication using the collaborative care model and a CBT-naive, midlevel behavioral health specialist is feasible and significantly more effective than usual care for primary care panic disorder. To evaluate the effect of combining cognitive-behaviour therapy (CBT) and medication in the treatment of obsessive-compulsive disorder (OCD).
                Twenty-nine subjects diagnosed with OCD according to Diagnostic and Statistical Manual of Mental Disorders (DSM-III-R) criteria were recruited through the Anxiety Clinic of Louis-H Lafontaine Hospital. They were evaluated at baseline and after treatment on the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) by a psychiatrist who was blind to treatment modality. Subjects rated their degree of resistance to their rituals and the strength of their obsessional beliefs. Subjects then received 1 of 4 treatments: medication and CBT simultaneously (n = 9), CBT only (n = 6), medication while on a wait-list for CBT (n = 6), or no treatment while on a wait-list for CBT (n = 5).
                Multivariate analysis revealed that Y-BOCS scores and clinical ratings significantly improved posttreatment in all groups except the nontreatment wait-list control group. Subjects in the 2 active treatment groups receiving CBT showed reduced strength in their obsessional beliefs. The subsequent administration of CBT to those groups on the wait-list also decreased the strength of their primary obsessional beliefs and beliefs about the consequences of not performing the rituals.
                Our results suggest that either CBT or medication alone is more effective than no treatment. The combination of CBT and medication seems to potentiate treatment efficacy, and we found it more clinically beneficial to introduce CBT after a period of medication rather than to start both therapies simultaneously. This study aimed to determine the efficacy and tolerability of adding quetiapine to a serotonin reuptake inhibitor in treatment-resistant obsessive-compulsive disorder (OCD). Twenty-one adult treatment-resistant OCD patients were randomized to 16 weeks of augmentation with either quetiapine (n = 11) or placebo (n = 10). Patients with significant comorbidities, including tic-spectrum disorders, were not included. The treatment was well tolerated, with only one premature dropout in each treatment-group. The primary analysis showed that individuals in the quetiapine-treated group showed a 14% mean improvement in baseline Yale-Brown Obsessive-Compulsive Scale scores at study endpoint compared with a 6% improvement in those treated with placebo, but this difference did not reach statistical significance (F<1). Three patients treated with quetiapine met criteria for clinical response, compared to one patient who was treated with placebo. Larger studies are needed to explore the efficacy of second generation antipsychotics, such as quetiapine, when used as adjunct treatment in resistant OCD. Selective serotonin re-uptake inhibitors (SSRIs) and cognitive behavioral therapies (CBTs) are both considered as first-line treatments for panic disorder, but the advantages of a combined therapy have yet to be definitively demonstrated. We evaluated in this pilot study the effects of combining SSRIs (vs. a placebo) with a very brief form of cognitive-behavioral therapy provided to all participants. Thirty-three subjects with DSM-IV panic disorder, with or without agoraphobia, were randomized to receive either paroxetine or a placebo with flexible dosing (10-50 mg/day). Medication visits were brief (15 min), infrequent (6 in total) and non-directive. An expert cognitive-behavior therapist administered one initial 45-min session and one subsequent 30-min session of very brief CBT (vbCBT) at weeks 5 and 7, respectively. Sessions were supplemented with educational and directive reading materials. Patients in both groups (i.e. vbCBT+paroxetine; vbCBT+placebo) improved similarly and substantially on most measures during the 10 weeks of acute treatment. At week 10, the proportion of panic-free patients was significantly higher in the paroxetine-treated group than in the placebo group (80 vs. 25%; P<0.007), as was the proportion of subjects who rated themselves as 'very much improved' at week 10 (60 vs. 13%; P<0.017). These findings point to the need for additional studies to confirm the effectiveness of very brief forms of CBT, and to document the circumstances in which combined treatment with an SSRI would be warranted. The empirical literature on treatment of obsessive-compulsive disorder (OCD) in children and adolescents supports the efficacy of short-term OCD-specific cognitive-behavior therapy (CBT) or medical management with selective serotonin reuptake inhibitors. However, little is known about their relative and combined efficacy.
                To evaluate the efficacy of CBT alone and medical management with the selective serotonin reuptake inhibitor sertraline alone, or CBT and sertraline combined, as initial treatment for children and adolescents with OCD.
                The Pediatric OCD Treatment Study, a balanced, masked randomized controlled trial conducted in 3 academic centers in the United States and enrolling a volunteer outpatient sample of 112 patients aged 7 through 17 years with a primary Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition diagnosis of OCD and a Children's Yale-Brown Obsessive-Compulsive Scale (CY-BOCS) score of 16 or higher. Patients were recruited between September 1997 and December 2002.
                Participants were randomly assigned to receive CBT alone, sertraline alone, combined CBT and sertraline, or pill placebo for 12 weeks.
                Change in CY-BOCS score over 12 weeks as rated by an independent evaluator masked to treatment status; rate of clinical remission defined as a CY-BOCS score less than or equal to 10.
                Ninety-seven of 112 patients (87%) completed the full 12 weeks of treatment. Intent-to-treat random regression analyses indicated a statistically significant advantage for CBT alone (P = .003), sertraline alone (P = .007), and combined treatment (P = .001) compared with placebo. Combined treatment also proved superior to CBT alone (P = .008) and to sertraline alone (P = .006), which did not differ from each other. Site differences emerged for CBT and sertraline but not for combined treatment, suggesting that combined treatment is less susceptible to setting-specific variations. The rate of clinical remission for combined treatment was 53.6% (95% confidence interval [CI], 36%-70%); for CBT alone, 39.3% (95% CI, 24%-58%); for sertraline alone, 21.4% (95% CI, 10%-40%); and for placebo, 3.6% (95% CI, 0%-19%). The remission rate for combined treatment did not differ from that for CBT alone (P = .42) but did differ from sertraline alone (P = .03) and from placebo (P<.001). CBT alone did not differ from sertraline alone (P = .24) but did differ from placebo (P = .002), whereas sertraline alone did not (P = .10). The 3 active treatments proved acceptable and well tolerated, with no evidence of treatment-emergent harm to self or to others.
                Children and adolescents with OCD should begin treatment with the combination of CBT plus a selective serotonin reuptake inhibitor or CBT alone. 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. The purpose of this treatment package design study was to investigate the differential efficacy of cognitive therapy or exposure in vivo with response prevention for obsessive compulsive disorder (OCD) versus the sequential combination with fluvoxamine. Patients with OCD (N = 117) were randomized to one of the following five conditions: a) cognitive therapy for weeks 1 to 16, b) exposure in vivo with response prevention for weeks 1 to 16, c) fluvoxamine for weeks 1 to 16 plus cognitive therapy in weeks 9 to 16, d) fluvoxamine for weeks 1 to 16 plus exposure in vivo with response prevention in weeks 9 to 16, or e) waiting list control condition for weeks 1 to 8 only. Assessments took place before treatment (pretest) and after 8 (midtest), and 16 weeks (posttest). In the first 8 weeks, six treatment sessions were delivered. During weeks 9 to 16, another 10 sessions were given. Thirty-one patients dropped out. Outcome was assessed by patient-, therapist- and assessor-ratings of the Anxiety Discomfort Scale, the Yale-Brown Obsessive Compulsive Scale, and the Padua Inventory-Revised. In contrast with the four treatments, after 8 weeks the waiting list control condition did not result in a significant decrease of symptoms. After 16 weeks of treatment, all four treatment packages were effective on these OCD ratings, but they did not differ among each other in effectiveness. In OCD, the sequential combination of fluvoxamine with cognitive therapy or exposure in vivo with response prevention is not superior to either cognitive therapy or exposure in vivo alone. Both cognitive-behavioral therapy and treatment with selective serotonin reuptake inhibitors (SSRIs) have proved to be effective in the treatment of panic disorder. The present study examined the effects of paroxetine added to continued cognitive-behavioral therapy in patients who were unsuccessfully treated with initial cognitive-behavioral therapy alone.
                161 patients with panic disorder with or without agoraphobia (DSM-IV criteria) underwent a manual-guided cognitive-behavioral therapy of 15 sessions. Forty-three unsuccessfully treated patients from this group were included in a double-blind, placebo-controlled, next-step treatment study consisting of continued cognitive-behavioral therapy plus adjunctive paroxetine at a dose of 40 mg/day or continued cognitive-behavioral therapy plus placebo.
                Overall, patients in the cognitive-behavioral therapy plus paroxetine condition improved significantly on agoraphobic behavior (p < .05) and anxiety discomfort (p < .01), whereas patients in the cognitive-behavioral therapy plus placebo condition did not. Effect sizes in the cognitive-behavioral therapy plus paroxetine condition ranged from 1.0 to 1.8 and in the cognitive-behavioral therapy plus placebo condition, from 0.4 to 1.0.
                Patients with panic disorder who are unsuccessfully treated with initial cognitive-behavioral therapy may benefit from the addition of an SSRI as a second treatment modality. The importance of timely evaluation of treatment results is emphasized. To test a collaborative-care, cognitive-behavioral therapy (CBT) program adjunctive to selective serotonin reuptake inhibitor (SSRI) treatment in HMO pediatric primary care.
                A randomized effectiveness trial comparing a treatment-as-usual (TAU) control condition consisting primarily of SSRI medication delivered outside the experimental protocol (n = 75) versus TAU SSRI plus brief CBT (n = 77). Participants were identified by a recent dispense of SSRI medication followed by telephone screening. Adolescents with a diagnosis of major depressive disorder (n = 152) were enrolled. The CBT program employed cognitive restructuring and/or behavioral activation training. Therapists consulted with prescribing pediatricians to improve medication adherence.
                Through 1-year follow-up, the authors found CBT advantages on the Short Form-12 Mental Component Scale (p = .04), reductions in TAU outpatient visits (p = .02), and days' supply of all medications (p = .01). No effects were detected for major depressive disorder episodes; a nonsignificant trend favoring CBT was detected on the Center for Epidemiology Depression Scale (p = .07).
                The authors detected a weak CBT effect, possibly rendered less significant by the small sample and likely attenuated by the unexpected reduction in SSRI pharmacotherapy in the CBT condition. Small, incremental improvements over monotherapy, such as observed in this study, most likely represent the new norm in adolescent depression treatment research. A series of small, mainly uncontrolled, studies have suggested that techniques adapted from cognitive-behavioural therapy (CBT) for depression can improve outcome in psychosis, but no large randomised controlled trial of intensive treatment for medication-resistant symptoms of psychosis has previously been published.
                Sixty participants who each had at least one positive and distressing symptom of psychosis that was medication-resistant were randomly allocated between a CBT and standard care condition (n = 28) and a standard care only control condition (n = 32). Therapy was individualised, and lasted for nine months. Multiple assessments of outcome were used.
                Over nine months, improvement was significant only in the treatment group, who showed a 25% reduction on the BPRS. No other clinical, symptomatic or functioning measure changed significantly. Participants had a low drop-out rate from therapy (11%), and expressed high levels of satisfaction with treatment (80%). Fifty per cent of the CBT group were treatment responders (one person became worse), compared with 31% of the control group (three people became worse and another committed suicide).
                CBT for psychosis can improve overall symptomatology. The findings provide evidence that even a refractory group of clients with a long history of psychosis can engage in talking about psychotic symptoms and their meaning, and this can improve outcome. The issue of panic disorder resistant to treatment (whether pharmacological or psychological) has attracted little research attention, despite its clinical frequency and importance. The aim of this study was to compare three treatment modalities, namely exposure alone (E), exposure associated with imipramine (EI) and cognitive therapy supplementing exposure (EC), in a sample of 21 patients with DSM-IV panic disorder and agoraphobia, who failed to respond to a first standard course of individual behavioural treatment based on exposure in vivo. Treatments were administered according to a cross-over, controlled design (E-EI-EC, EI-EC-E, EC-E-EI). Twelve of the 21 patients achieved remission (panic-free status) during the trial. In 8 cases this occurred after exposure alone (E) and in two cases each after the other treatments (EI and EC). The results revealed a significant effect of the factor time on a number of variables, and the superiority of exposure alone compared to other treatment modalities with regard to some variables. These findings suggest that long-term behavioural treatment based on exposure may be necessary in some patients, and may induce clinical remission. However, patients who do not respond to exposure show poor tolerance of and compliance with pharmacological treatment, and are unlikely to achieve remission with imipramine or cognitive therapy, even though this may occur in individual cases. To examine the influence of psychiatric comorbidity on response and relapse rates in children and adolescents treated with paroxetine for obsessive-compulsive disorder (OCD).
                Patients responding following 16 weeks of treatment (phase I) were randomized to continued paroxetine or to placebo for 16 additional weeks (phase II). OCD response (phase I) and relapse (phase II) criteria were based on the Clinical Global Impression-Improvement Scale and the Children's Yale-Brown Obsessive Compulsive Scale. The presence of OCD and other psychiatric disorders was ascertained using the Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version interview.
                At entry, 193 of 335 (57.6%) patients had at least one psychiatric disorder in addition to OCD, and 102 of 335 (30.4%) had multiple other disorders. Although the response rate to paroxetine in the overall population was high (71%), the response rates in patients with comorbid attention deficit hyperactivity disorder, tic disorder, or oppositional defiant disorder (56%, 53%, and 39%, respectively) were significantly less than in patients with OCD only (75%) (intent-to-treat population, last observation carried forward analysis, p < 0.05). Psychiatric comorbidity was associated with a greater rate of relapse in the total patient population (46% for one or more comorbid disorders [p = 0.04] and 56% for two or more comorbid disorders [p < 0.05] vs. 32% for no comorbidity).
                The results of these post hoc analyses show that comorbid illness adversely impacted response to pharmacotherapy with paroxetine in pediatric OCD and significantly increased risk of relapse following withdrawal from treatment. Continued paroxetine treatment reduced the relapse rates in all groups compared with placebo, including those with comorbid illness. Because pediatric OCD is frequently comorbid with other psychiatric disorders, results of randomized, controlled pediatric OCD trials that use multiple exclusion criteria may not generalize to more naturalistic OCD samples. To examine the efficacy of a developmentally appropriate parent-child cognitive behavioral therapy (CBT) protocol for anxiety disorders in children ages 4-7 years.
                Design: Randomized wait-list controlled trial. Conduct: Sixty-four children (53% female, mean age 5.4 years, 80% European American) with anxiety disorders were randomized to a parent-child CBT intervention (n = 34) or a 6-month wait-list condition (n = 30). Children were assessed by interviewers blind to treatment assignment, using structured diagnostic interviews with parents, laboratory assessments of behavioral inhibition, and parent questionnaires. Analysis: Chi-square analyses of outcome rates and linear and ordinal regression of repeated measures, examining time by intervention interactions.
                The response rate (much or very much improved on the Clinical Global Impression Scale for Anxiety) among 57 completers was 69% versus 32% (CBT vs. controls), p < .01; intent-to-treat: 59% vs. 30%, p = .016. Treated children showed a significantly greater decrease in anxiety disorders (effect size [ES] = .55) and increase in parent-rated coping (ES = .69) than controls, as well as significantly better CGI improvement on social phobia/avoidant disorder (ES = .95), separation anxiety disorder (ES = .82), and specific phobia (ES = .78), but not on generalized anxiety disorder. Results on the Child Behavior Checklist Internalizing scale were not significant and were limited by low return rates. Treatment response was unrelated to age or parental anxiety but was negatively predicted by behavioral inhibition. Gains were maintained at 1-year follow-up.
                Results suggest that developmentally modified parent-child CBT may show promise in 4- to 7-year-old children.
                (PsycINFO Database Record (c) 2010 APA, all rights reserved). Children with high-functioning autism spectrum disorders (ASD) are at high risk for developing significant anxiety. Anxiety can adversely impact functioning across school, home and community environments. Cognitive behavioral therapies (CBT) are frequently used with success for children with anxiety symptoms. Modified CBT interventions for anxiety in children with ASD have also yielded promising results.
                Fifty children with high-functioning ASD and anxiety were randomizedto group CBT or treatment-as-usual (TAU) for 12 weeks. Independent clinical evaluators, blind to condition, completed structured interviews (Anxiety Disorders Interview Schedule – Parent Version;ADIS-P) pre- and post-intervention condition.
                Forty-seven children completed either the CBT or TAU condition. Results indicated markedly better outcomes for the CBT group. Significant differences by group were noted in Clinician Severity Ratings, diagnostic status, and clinician ratings of global improvement. In the intent-to-treat sample, 10 of 20 children (50%) in the CBT group had a clinically meaningful positive treatment response, compared to 2 of 23 children (8.7%) in the TAU group.
                Initial results from this randomized, designed treatment study suggest that agroup CBT intervention specifically developed for children with ASD may be effective in decreasing anxiety. Limitations of this study include small sample size, lack of an attention control group, and use of outcome measures normed with typically developing children Although cognitive-behavior therapy (CBT) is an efficacious treatment for generalized anxiety disorder (GAD) in younger adults, little is known about its efficacy in older patients. Investigations to date have tested group-format or otherwise nonstandard versions of CBT. The studies described here are, to our knowledge, the first to test the efficacy of individual-format CBT administered in a mental health clinic for treatment of late-life GAD.
                Study 1 tested a standard version, and Study 2 tested an enhanced version (ECBT) that included learning and memory aids designed to make the therapy more effective with elderly patients (e.g., homework reminder and troubleshooting calls, weekly review of all concepts and techniques).
                Study 1 CBT participants showed significant improvement on GAD severity ratings. Study 2 ECBT participants showed significant improvement on two self-report measures, rates of posttreatment GAD, and GAD severity ratings. ECBT resulted in improvement on more measures and yielded larger effect sizes than standard CBT, when each was compared against a wait-list control group.
                Results of these pilot studies suggest that standard individual-format CBT may not be optimally effective for treating late-life GAD; thus, ECBT should be tested further in randomized trials. Improving the quality of mental health care requires moving clinical interventions from controlled research settings into real-world practice settings. Although such advances have been made for depression, little work has been performed for anxiety disorders.
                To determine whether a flexible treatment-delivery model for multiple primary care anxiety disorders (panic, generalized anxiety, social anxiety, and posttraumatic stress disorders) would be better than usual care (UC).
                A randomized controlled effectiveness trial of Coordinated Anxiety Learning and Management (CALM) compared with UC in 17 primary care clinics in 4 US cities. Between June 2006 and April 2008, 1004 patients with anxiety disorders (with or without major depression), aged 18 to 75 years, English- or Spanish-speaking, were enrolled and subsequently received treatment for 3 to 12 months. Blinded follow-up assessments at 6, 12, and 18 months after baseline were completed in October 2009.
                CALM allowed choice of cognitive behavioral therapy (CBT), medication, or both; included real-time Web-based outcomes monitoring to optimize treatment decisions; and a computer-assisted program to optimize delivery of CBT by nonexpert care managers who also assisted primary care clinicians in promoting adherence and optimizing medications.
                Twelve-item Brief Symptom Inventory (BSI-12) anxiety and somatic symptoms score. Secondary outcomes included proportion of responders (> or = 50% reduction from pretreatment BSI-12 score) and remitters (total BSI-12 score < 6).
                A significantly greater improvement for CALM vs UC in global anxiety symptoms was found (BSI-12 group mean differences of -2.49 [95% confidence interval {CI}, -3.59 to -1.40], -2.63 [95% CI, -3.73 to -1.54], and -1.63 [95% CI, -2.73 to -0.53] at 6, 12, and 18 months, respectively). At 12 months, response and remission rates (CALM vs UC) were 63.66% (95% CI, 58.95%-68.37%) vs 44.68% (95% CI, 39.76%-49.59%), and 51.49% (95% CI, 46.60%-56.38%) vs 33.28% (95% CI, 28.62%-37.93%), with a number needed to treat of 5.27 (95% CI, 4.18-7.13) for response and 5.50 (95% CI, 4.32-7.55) for remission.
                For patients with anxiety disorders treated in primary care clinics, CALM compared with UC resulted in greater improvement in anxiety symptoms, depression symptoms, functional disability, and quality of care during 18 months of follow-up.
                clinicaltrials.gov Identifier: NCT00347269. Although serotonin reuptake inhibitors (SRIs) are the most effective pharmacologic treatment currently available for patients with obsessive-compulsive disorder (OCD), 40% to 60% of patients do not respond to this treatment. This study was conducted to evaluate the efficacy and tolerability of quetiapine in addition to an SRI for treatment-refractory patients with OCD.
                Forty patients (10 men/30 women, mean +/- SD age = 35.2 +/- 12.1 years; range, 18-60 years) with primary OCD according to DSM-IV criteria who were recruited between February 2001 and December 2002 were randomly assigned in an 8-week, double-blind, placebo-controlled trial to receive dosages titrated upward to 300 mg/day of quetiapine (N = 20) or placebo (N = 20) in addition to their SRI treatment. At entry, all patients were unresponsive to courses of treatment with at least 2 different SRIs at a maximum tolerated dose for 8 weeks. During the study, primary efficacy was assessed according to change from baseline on the Yale-Brown Obsessive Compulsive Scale (Y-BOCS). A responder was defined as having a final Clinical Global Impressions-Improvement scale rating of "very much improved" or "much improved" and a decrease of > or = 35% in Y-BOCS score.
                An intent-to-treat, last-observation-carried-forward analysis demonstrated a mean +/- SD decrease in Y-BOCS score of 9.0 +/- 7.0 (31%) in the quetiapine group and 1.8 +/- 3.4 (7%) in the placebo group (F=16.99, df=1,38; p <.001). Eight (40%) of 20 patients in the quetiapine group and 2 (10%) of 20 patients in the placebo group were responders (chi2=4.8, df=1, p=.028). The most common side effects in the quetiapine group were somnolence, dry mouth, weight gain, and dizziness.
                The results of this study show that quetiapine in addition to an SRI is beneficial for patients with OCD who do not respond to SRI treatment alone. To determine whether individualized advice on non-pharmacological strategies for hospitalized older patients with confusion and behavioral problems can improve levels of agitation and reduce the use of psychotropic medication.
                Pragmatic randomized controlled trial in two metropolitan teaching hospitals in South Australia. Seventy-one older patients with confusion and a behavioral disturbance were randomly allocated to receive either an assessment and ongoing individualized advice from an extended practice nurse on non-pharmacological strategies or usual care. Usual care included an assessment by a geriatrician.
                Primary outcomes were levels of agitation (Pittsburgh Agitation Scale), appropriateness of psychotropic medication prescribing (Medication Appropriateness Index) and levels of psychotropics administered (chlorpromazine and diazepam dose equivalents). Secondary outcomes were length of stay, discharge destination, number of falls, restraint use and satisfaction from nursing staff and next of kin.
                Levels of agitation were modest at baseline with mean PAS intervention group 3.4 (SD = 0.5) and control group 4.0 (SD = 0.4) and both groups improved over time to 1.7 (SD = 0.4) for the intervention group and 1.8 (SD = 0.3) for the control group on the final day of data collection. Median length of follow-up was nine days. There was no effect of the intervention on levels of agitation, amount and appropriateness of psychotropic medication prescribed and administered, falls, length of stay, discharge destination, restraint use and nursing and next of kin satisfaction.
                A nursing consultation service providing individualized non-pharmacological advice does not improve patient agitation or use of psychotropic medication for older patients with confusion and behavioral problems in an acute hospital. Panic disorder (PD) may be treated with drugs, psychosocial intervention, or both, but the relative and combined efficacies have not been evaluated in an unbiased fashion.
                To evaluate whether drug and psychosocial therapies for PD are each more effective than placebo, whether one treatment is more effective than the other, and whether combined therapy is more effective than either therapy alone.
                Randomized, double-blind, placebo-controlled clinical trial conducted in 4 anxiety research clinics from May 1991 to April 1998.
                A total of 312 patients with PD were included in the analysis.
                Patients were randomly assigned to receive imipramine, up to 300 mg/d, only (n=83); cognitive-behavioral therapy (CBT) only (n=77); placebo only (n=24); CBT plus imipramine (n=65); or CBT plus placebo (n=63). Patients were treated weekly for 3 months (acute phase); responders were then seen monthly for 6 months (maintenance phase) and then followed up for 6 months after treatment discontinuation.
                Treatment response based on the Panic Disorder Severity Scale (PDSS) and the Clinical Global Impression Scale (CGI) by treatment group.
                Both imipramine and CBT were significantly superior to placebo for the acute treatment phase as assessed by the PDSS (response rates for the intent-to-treat [ITT] analysis, 45.8%, 48.7%, and 21.7%; P=.05 and P=.03, respectively), but were not significantly different for the CGI (48. 2%, 53.9%, and 37.5%, respectively). After 6 months of maintenance, imipramine and CBT were significantly more effective than placebo for both the PDSS (response rates, 37.8%, 39.5%, and 13.0%, respectively; P=.02 for both) and the CGI (37.8%, 42.1%, and 13.0%, respectively). Among responders, imipramine produced a response of higher quality. The acute response rate for the combined treatment was 60.3% for the PDSS and 64.1% for the CGI; neither was significantly different from the other groups. The 6-month maintenance response rate for combined therapy was 57.1% for the PDSS (P=.04 vs CBT alone and P=.03 vs imipramine alone) and 56.3% for the CGI (P=.03 vs imipramine alone), but not significantly better than CBT plus placebo in either analysis. Six months after treatment discontinuation, in the ITT analysis CGI response rates were 41.0% for CBT plus placebo, 31.9% for CBT alone, 19.7% for imipramine alone, 13% for placebo, and 26.3% for CBT combined with imipramine.
                Combining imipramine and CBT appeared to confer limited advantage acutely but more substantial advantage by the end of maintenance. Each treatment worked well immediately following treatment and during maintenance; CBT appeared durable in follow-up. JAMA. 2000;283:2529-2536 The present study investigated the efficacy of a coping-technique, applied relaxation (AR) and cognitive therapy (CT), in the treatment of generalized anxiety disorder. Thirty-six outpatients fulfilling the DSM-III-R criteria for generalized anxiety were assessed with independent assessor ratings and self-report scales before and after treatment and at a 1 yr follow-up. The patients were randomized and treated individually for 12 weekly sessions. The results showed that both treatments yielded large improvements, which were maintained, or furthered at follow-up. There was no difference between AR and CT on any measure. The drop-out rate was 12% for AR and 5% for CT. The proportions of clinically significantly improved patients were 53 and 62% at post-treatment and 67 and 56% at follow-up for AR and CT, respectively. Besides affecting generalized anxiety the treatments also yielded marked and lasting changes on ratings of worry, cognitive and somatic anxiety and depression. The conclusion that can be drawn is that both AR and CT have potential as treatments for generalized anxiety disorder but they have to be developed further in order to increase the efficacy to the level usually seen in panic disorder, 80-85% clinically improved.
Medication treatments can be effective in paediatric anxiety disorders, acting to reduce core symptoms, and should be considered as part of the treatment of these disorders. The greatest number of trials showing efficacy to date have assessed the SSRIs in treating paediatric OCD.
There is no clear evidence to show that any particular class of medication is more effective or better tolerated than any other. As quantitative data was only available for the SSRIs and venlafaxine the routine use of benzodiazepines cannot be recommended, especially given concerns of dependency and treatment -related emergent adverse events associated with this class of drugs. 

Future RCTs could help identify potential clinical moderators of treatment efficacy. Studies of the long-term efficacy of medication treatment, optimal dosage, as well as direct comparisons of pharmacotherapy and psychotherapy are also warranted.
