Studies on individual psychotherapy indicate that some interventions may reduce the number of recurrences in bipolar patients. However, there has been a lack of structured, well-designed, blinded, controlled studies demonstrating the efficacy of group psychoeducation to prevent recurrences in patients with bipolar I and II disorder.
                One hundred twenty bipolar I and II outpatients in remission (Young Mania Rating Scale score <6, Hamilton Depression Rating Scale-17 score <8) for at least 6 months prior to inclusion in the study, who were receiving standard pharmacologic treatment, were included in a controlled trial. Subjects were matched for age and sex and randomized to receive, in addition to standard psychiatric care, 21 sessions of group psychoeducation or 21 sessions of nonstructured group meetings. Subjects were assessed monthly during the 21-week treatment period and throughout the 2-year follow-up.
                Group psychoeducation significantly reduced the number of relapsed patients and the number of recurrences per patient, and increased the time to depressive, manic, hypomanic, and mixed recurrences. The number and length of hospitalizations per patient were also lower in patients who received psychoeducation.
                Group psychoeducation is an efficacious intervention to prevent recurrence in pharmacologically treated patients with bipolar I and II disorder. The efficacy and effectiveness of cognitive therapy (CT) is well established for unipolar disorders, but little is known about its utility in bipolar disorders. This study aimed to explore the feasibility and efficacy of using CT as an adjunct to usual psychiatric treatment in this patient population.
                Subjects referred by general adult psychiatrists were assessed by and independent rater and then randomly allocated to immediate CT (N = 21) or 6-month waiting-list control, which was then followed by CT (N = 21). Observer and self-ratings of symptoms and functioning were undertaken immediately prior to CT, after a 6-month course of CT and a further 6-months later. Data on relapse and hospitalization rates in the 18 months before and after commencing CT were also collected.
                At 6-month follow-up, subjects allocated to CT showed statistically significantly greater improvements in symptoms and functioning as measured on the Beck Depression Inventory, the Internal State Scale, and the Global Assessment of Functioning than those in the waiting-list control group. In the 29 patients who eventually received CT, relapse rates in the 1 8 months after commencing CT showed a 60 % reduction in comparison with the 18 months prior to commencing CT. Seventy per cent of subjects who commenced therapy viewed CT as highly acceptable.
                Although the results of this study are encouraging, the use of CT in subjects with bipolar disorders is more complex than in unipolar disorders and requires a high level of therapist expertise. The therapy may prove to be particularly useful in the treatment of bipolar depression. Efficacy trials suggest that structured psychological therapies may significantly reduce recurrence rates of major mood episodes in individuals with bipolar disorders.
                To compare the effectiveness of treatment as usual with an additional 22 sessions of cognitive-behavioural therapy (CBT).
                We undertook a multicentre, pragmatic, randomised controlled treatment trial (n=253). Patients were assessed every 8 weeks for 18 months.
                More than half of the patients had a recurrence by 18 months, with no significant differences between groups (hazard ratio=1.05; 95% CI 0.74-1.50). Post hoc analysis demonstrated a significant interaction (P=0.04) such that adjunctive CBT was significantly more effective than treatment as usual in those with fewer than 12 previous episodes, but less effective in those with more episodes.
                People with bipolar disorder and comparatively fewer previous mood episodes may benefit from CBT. However, such cases form the minority of those receiving mental healthcare. The efficacy of adjunctive psychosocial interventions such as cognitive behaviour therapy (CBT) for bipolar disorder (BD) has been demonstrated in several uncontrolled and controlled studies. However, these studies compared CBT to either a waiting list control group, brief psycho-education or treatment as usual (TAU). Our primary aim was to determine whether CBT is superior to supportive therapy (ST) of equal intensity and frequency in preventing relapse and improving outcome at post-treatment. A secondary aim was to look at predictors of survival time.
                We conducted a randomized controlled trial (RCT) at the Department of Psychology, University of Tübingen, Germany (n=76 patients with BD). Both CBT and ST consisted of 20 sessions over 9 months. Patients were followed up for a further 24 months.
                Although changes over time were observed in some variables, they were not differentially associated with CBT or ST. CBT showed a non-significant trend for preventing any affective, specifically depressive episode during the time of therapy. Kaplan-Meier survival analyses revealed that 64.5% of patients experienced a relapse during the 33 months. The number of prior episodes, the number of therapy sessions and the type of BD predicted survival time.
                No differences in relapse rates between treatment conditions were observed, suggesting that certain shared characteristics (e.g. information, systematic mood monitoring) might explain the effects of psychosocial treatment for BD. Our results also suggest that a higher number of prior episodes, a lower number of therapy sessions and a diagnosis of bipolar II disorder are associated with a shorter time before relapse. In a previous randomized controlled study, the authors reported significant beneficial effects of cognitive therapy for relapse prevention in bipolar disorder patients up to 1 year. This study reports additional 18-month follow-up data and presents an overview of the effect of therapy over 30 months.
                Patients with DSM-IV bipolar I disorder (N=103) suffering from frequent relapses were randomly assigned into a cognitive therapy plus medication group or a control condition of medication only. Independent raters, who were blind to patient group status, assessed patients at 6-month intervals.
                Over 30 months, the cognitive therapy group had significantly better outcome in terms of time to relapse. However, the effect of relapse prevention was mainly in the first year. The cognitive therapy group also spent 110 fewer days (95% CI=32 to 189) in bipolar episodes out of a total of 900 for the whole 30 months and 54 fewer days (95% CI=3 to 105) in bipolar episodes out of a total of 450 for the last 18 months. Multivariate analyses of variance showed that over the last 18 months, the cognitive therapy group exhibited significantly better mood ratings, social functioning, coping with bipolar prodromes, and dysfunctional goal attainment cognition.
                Patients in the cognitive therapy group had significantly fewer days in bipolar episodes after the effect of medication compliance was controlled. However, the results showed that cognitive therapy had no significant effect in relapse reduction over the last 18 months of the study period. Further studies should explore the effect of booster sessions or maintenance therapy. The purpose of this study was to evaluate the effectiveness of an activating intervention designed to reduce sick leave duration in patients with emotional distress or minor mental disorders.
                In a 1.5-year randomized controlled trial, 194 patients with minor mental disorders received either an experimental intervention by social workers or general practitioners' usual care. The intervention focused on understanding causes, developing and implementing problem-solving strategies and promoting early work resumption. Outcome measures were sick leave duration, mental health and physical health (questionnaires included the Hospital Anxiety and Depression Scale, the Four-Dimensional Symptom Questionnaire and SF-36), all measured at baseline at and 3, 6 and 18 months later. Multilevel analyses were used to evaluate differences between groups.
                The groups did not differ significantly on any of the outcome measures, except that the experimental group reported higher satisfaction with treatment.
                Although the intervention has benefits, it was not successful at its primary goal (i.e., to reduce sick leave duration in patients with emotional distress or minor mental disorders). Programs aimed at the reduction of sick leave duration may yield better results if targeted at patients with more severe emotional problems than at those with exclusively emotional distress or minor mental disorders, or if delivered by caregivers who are closer to the work environment than are social workers, such as occupational physicians. The ACE project involved 62 participants with a first episode of psychosis randomly assigned to either a cognitive behaviour therapy (CBT) intervention known as Active Cognitive Therapy for Early Psychosis (ACE) or a control condition known as Befriending. The study hypotheses were that: (1) treating participants with ACE in the acute phase would lead to faster reductions in positive and negative symptoms and more rapid improvement in functioning than Befriending; (2) these improvements in symptoms and functioning would be sustained at a 1-year follow-up; and (3) ACE would lead to fewer hospitalizations than Befriending as assessed at the 1-year follow-up.
                Two therapists treated the participants across both conditions. Participants could not receive any more than 20 sessions within 14 weeks. Participants were assessed by independent raters on four primary outcome measures of symptoms and functioning: at pretreatment, the middle of treatment, the end of treatment and at 1-year follow-up. An independent pair of raters assessed treatment integrity.
                Both groups improved significantly over time. ACE significantly outperformed Befriending by improving functioning at mid-treatment, but it did not improve positive or negative symptoms. Past the mid-treatment assessment, Befriending caught up with the ACE group and there were no significant differences in any outcome measure and in hospital admissions at follow-up.
                There is some preliminary evidence that ACE promotes better early recovery in functioning and this finding needs to be replicated in other independent research centres with larger samples. Outcome for bipolar disorder remains suboptimal despite the availability of efficacious treatments. To improve treatment effectiveness in clinical practice, a Veterans Affairs study team created a care model conceptually similar to the lithium clinics of the 1970s but augmented by principles of more recent collaborative care models for chronic medical illnesses. This intervention consists of improving patients' self-management skills through psychoeducation; supporting providers' decision making through simplified practice guidelines; and enhancing access to care, continuity of care, and information flow through the use of a nurse care coordinator. In this article, which is part I of a two-part report, the authors summarize the conceptual background and development of the intervention, describe the design of a three-year, 11-site randomized effectiveness trial, and report data describing its successful implementation. Trial design emphasized aspects of effectiveness to support generalizability of the findings and eventual dissemination of the intervention. Part II (see companion article, this issue) reports clinical, functional, and overall cost outcomes of the trial. Several previous studies have established that low treatment adherence is common among bipolar patients and may explain high rates of recurrence. On the other hand, some patients keep relapsing even when they strictly follow their prescribed somatic treatments. Psychological interventions such as psychoeducation may foster early recognition of prodromal symptoms and minimize the risk of relapse. To date, studies assessing the usefulness of psychoeducation in fully compliant patients are lacking.
                This was a single-blind, randomized, prospective clinical trial on the efficacy of group psychoeducation in remitted fully compliant DSM-IV bipolar I patients (N = 25) who were compared with a group with similar characteristics (N = 25) who did not receive psychoeducation. All patients received naturalistic pharmacologic treatment. Recruitment began in 1997 and follow-up was completed in January 2002. The follow-up phase comprised 2 years during which all patients continued receiving naturalistic treatment without psychological intervention and were assessed monthly on several outcome measures.
                At the end of the 2-year follow-up, 23 subjects (92%) in the control group fulfilled criteria for recurrence versus 15 patients (60%) in the psychoeducation group (p < .01). The number of total recurrences and the number of depressive episodes were significantly lower in psychoeducated patients.
                Although the present study has the limitation of small sample size, psychoeducation showed its efficacy in preventing relapses in bipolar I patients who were adherent to drug treatment. The action of psychoeducation seems to go beyond compliance enhancement and may support a tripod model composed by lifestyle regularity and healthy habits, early detection of prodromal signs followed by prompt drug intervention, and finally treatment compliance.
This review shows a beneficial effect of EWS in time to recurrence, percentage of people hospitalised and functioning in people with bipolar disorder. However, the absence of data on the primary outcome measure in so many included studies is a source of concern and a potential source of bias. Mental health services should consider routinely providing EWS interventions to adults with bipolar disorder, as they appear to reduce hospitalisation and therefore may be cost-effective.
