Clinical effectiveness and acceptability of structured group psychoeducation versus optimised unstructured peer support for patients with remitted bipolar disorder (PARADES): a pragmatic, multicentre, observer-blind, randomised controlled superiority trial

Who benefits from digital interventions for bipolar disorder? Stage of illness characteristics as predictors of changes in quality of life

OBJECTIVES

This study explored the potential role of stage-related variables in intervention outcomes in bipolar disorder (BD). Specifically, we aimed to identify which subgroups of individuals were most likely to experience improved quality of life following digitally delivered psychosocial interventions for BD.

METHODS

The study involved a secondary analysis of combined data from two randomised control trials (RCTs). Each trial assessed the effectiveness of digitally delivered interventions for improving quality of life, in late-stage (ORBIT RCT) or early-stage (BETTER RCT) BD. Three iterations of cluster analyses were performed, identifying subgroups of individuals based on (i) current phenomenology, (ii) course of illness and (iii) medication response. The resultant subgroups were compared with regard to changes in quality of life pre-post intervention, via repeated measures ANOVAs.

RESULTS

In each cluster analysis, two clusters were found. The current phenomenology clusters reflected two impairment levels, 'moderate impairment' and 'low impairment'. The course of illness clusters reflected 'more chronicity' and 'less chronicity' and the medication response clusters reflected 'good medication response' and 'poor medication response'. Differences in changes in quality of life over time were observed between the two current phenomenology clusters and between the medication response clusters, while the course of illness subgroups did not respond differently.

CONCLUSIONS

There are at least two distinct groups of treatment-seeking individuals with established BD, based on illness features with previously established links to different illness stages. Clusters within the current phenomenology and medication response domains demonstrated significantly different trajectories of QoL change over time in the context of our interventions, highlighting potential implications for treatment selection aligned with precision psychiatry.

Effectiveness of structured group psychoeducation for people with bipolar disorder in Rwanda: A randomized open-label superiority trial

BACKGROUND

Psychoeducation is a cornerstone as an add-on to pharmacotherapy in standard care for individuals with bipolar disorder. However, evidence of the effectiveness of psychoeducation in low-resource settings is scarce.

AIMS

We aimed to assess the effectiveness of structured group psychoeducation versus waiting list on relapse prevention for individuals with bipolar disorder in Rwanda, a low-income country.

METHODS

This was a randomized open-label superiority trial. Participants aged 18 years or older with bipolar disorder were recruited at the two referral hospitals for mental health in Rwanda and randomly assigned 12 sessions of group psychoeducation or a waiting list. The program was tailored to the setting and co-designed with patients and clinicians. The follow-up period was 12 months, and the primary outcome mean number of psychiatric hospitalizations.

RESULTS

In February and March 2021, 154 participants were randomly assigned to receive group psychoeducation (n = 78) or to a waiting list (n = 76). The retention rate was high, with only three discontinuing the psychoeducation once they had received a session. Despite limited use of first-line pharmacotherapy, the psychoeducation reduced the risk of hospitalization by half during the 12-month follow-up (RR: 0.50(95 % CI 0.26-0.95)). Yet, no change in medical adherence was observed.

LIMITATION

Weekly assessment of clinical status was not feasible.

CONCLUSION

Structured group psychoeducation for bipolar disorder in a low-resource setting has a protective effect against readmission despite limited access to first-line pharmacotherapy. Further studies are needed to assess the effectiveness of the program in more decentralized settings with less highly trained staff.

Current practices of psychoeducation interventions with persons with bipolar disorders: a literature review

This review sought to summarize the literature on current practices and forms of psychoeducation in the management of patients with bipolar disorder (BD), including only randomized controlled trials to ensure the best level of evidence. An extensive review of the available literature was conducted using PubMed/MEDLINE, Embase, and PsychInfo databases from inception to April 28th, 2022. The search yielded 381 studies. Seventy articles were included after removing duplicates and applying the inclusion/exclusion criteria. A best-evidence synthesis was used to identify the key results of each study and summarize the outcomes. Eleven descriptive categories were made. They encompass different forms of psychoeducation compared or combined with other psychosocial interventions, varying in setting (individual or group), with or without family members, structured or unstructured, mediated or not by digital tools (smartphone, internet). Globally, these studies show that psychoeducation is important in the treatment of BD, as it leads to a decrease in relapses, mood episodes, hospitalizations, and improved functioning or quality of life. Some studies also showed the benefits of psychoeducation on the patient's level of knowledge of pharmacological treatment and the disorder or compliance with medication, as well as reduced self-stigma. The limitations of this review are linked to the selection of only RCTs and the reliance on their post-hoc analyses. This review confirms the benefit of psychoeducation and psychosocial interventions on the evolution of BD (in different outcomes, including quality of life, relapse, and rehospitalization rates, for example). More recent interventions, such as mindfulness or online psychoeducation, represent an interesting option but more evidence is needed.

Anxiety and mood disorders in forcibly displaced people across the world

PURPOSE OF REVIEW

Displaced persons around the world have intensified in the previous decade and are predicted to rise further with greater global instability. The mental health issues involved with fleeing one's home, and attempting to make a new life in a host country need to be understood and addressed.

RECENT FINDINGS

Prevalence of anxiety and mood disorders, including posttraumatic stress disorder appear to be higher for displaced peoples than for the population in the host country. This is consistent across different methods. Traumatic life events in the country of origin as well as during flight contribute to symptom severity. Factors in the host country increasing severity including isolation, discrimination, low social support. There are successfully implemented intercultural interventions at the individual level of the practitioner, as well as at the institutional level.

SUMMARY

There are many possibilities for successful interventions in displaced people, realizing this at a scale appropriate to the size of the problem remains a challenge.

Potential advantages of combining randomized controlled trials with qualitative research in mood and anxiety disorders - A systematic review

INTRODUCTION

Most randomized controlled trials (RCTs) of mood and anxiety disorders employ solely quantitative methods. Supplementing quantitative data with qualitative methods, a so-called mixed-method approach, would seem useful, however this area has not been rigorously reviewed. We undertook a systematic review of RCTs of mood and anxiety disorders that employed concurrent quantitative data collection and qualitative methods exploring the participants' perspective, with the aim of 1. determining the number of such studies, 2. describing study characteristics, and 3. identifying potential advantages of a mixed-method approach.

METHODS

Following PRISMA guidelines, a systematic literature search for RCTs of mood and anxiety disorders, concurrently applying quantitative and qualitative methods, was conducted using EMBASE, PsycINFO and Pubmed, from their inception to February 2021. Categories of potential advantages of this mixed method approach were developed.

RESULTS

A total of 45 RCTs were included. The qualitative components typically included 10-40 participants, mostly consisting of interviews after the intervention. The majority of papers did not state a specific rationale for using a mixed method approach. Four categories of advantages emerged: 1. determine acceptability/feasibility, 2. investigate efficacy, 3. inform implementation in clinical practice and 4. generate new hypotheses based on the combination of quantitative and qualitative data.

LIMITATIONS

Lack of cross-referencing and consistent terminology challenged identification of relevant publications.

CONCLUSION

There are a number of potential advantages of applying mixed method approaches in RCTs within psychiatric research. Intentional consideration of such advantages early in trial design may increase the likelihood of gaining added value.

A Brief Psychoeducation Intervention to Prevent Rehospitalization in Severe Mental Disorder Inpatients

ABSTRACT

The efficacy of medium- to long-term psychoeducation in preventing relapse and hospitalization in people with severe mental disorders (SMDs) is robust. However, the evidence is inconclusive in brief interventions and individual modalities. The aim of this randomized clinical trial in SMD inpatients is to analyze the efficacy of a brief psychoeducation intervention added to treatment-as-usual, in improving the rehospitalization rate at 3 and 6 months after discharge. Fifty-one SMD inpatients were randomized to the intervention ( n = 24) or control group ( n = 27). Low insight and poor medication adherence were the most prevalent risk factors at admission. No significant differences were observed in the rehospitalization rate at 3 and 6 months after discharge. On the overall sample, the number of previous hospitalizations was a rehospitalization predictor at 3 (odds ratio [OR], 1.25; 95% confidence interval [CI], 1.01-1.56; p = 0.04) and 6 months (OR, 1.85; 95% CI, 1.17-2.91; p = 0.009). SMD people require multimodal and persistent approaches focused on insight and medication adherence to prevent rehospitalizations.

Social and environmental variables as predictors of mania: a review of longitudinal research findings

Considerable evidence suggests that psychosocial variables can shape the course of bipolar disorder. Here, though, we focus on the more specific idea that the social environment can predict the course of mania. We systematically review evidence from longitudinal studies concerning how social support, family interactions, traumatic life events, and recent life events relate to the age of onset, the frequency of episode recurrence, and the severity of manic symptoms. Although we find some evidence that the course of mania can be worsened by social environmental factors, the links are specific. Among social variables, some studies indicate that conflict and hostility are predictive, but more general social relationship qualities have not been found to predict mania. Some research indicates that childhood trauma, and recent life events involving goal attainment or sleep disruption can predict mania. Taken together, the profile of variables involving recent exposure that are most predictive include those that are activating, reward-related, or sleep-disrupting, which fits with general psychological hypotheses of behavioral activation and sleep disruption as important for mania. We discuss gaps in the literature, and we note future directions for research, including the need for more integrative, longitudinal research on a fuller range of social and biological risk variables.

A Meta-Analysis of Group Cognitive Behavioral Therapy and Group Psychoeducation for Treating Symptoms and Preventing Relapse in People Living with Bipolar Disorder

Objectives: This meta-analysis aims to evaluate the treatment outcomes of patients treated with Group cognitive behavioural therapy (GCBT) or group psychoeducation (GPE) as an adjunct to pharmacotherapy. Methods: Systematic search of PubMed, EMBASE, PsycINFO, and CENTRAL from inception till 1 March 2022 was conducted. Randomized-controlled-trials (RCTs) comparing GCBT/GPE with controls (treatment-as-usual/individualized therapy) in adults with bipolar disorder were eligible. The outcomes were relapse rates of any depressive or manic episodes and control of depressive and manic symptoms post-intervention. Overall odds-ratio was used to evaluate the relapse rates. Standard Mean Differences were pooled using a random-effects model for the control of depressive and manic symptoms. Results: 25 articles were assessed full-text independently by two members, and 11 studies were included in this meta-analysis. 601 and 590 participants were randomized into group-therapy (GCBT/GPE) and control, respectively. GPE significantly reduces relapse rates at post-intervention with Odds ratio of 0.43 (95% CI = 0.28-to-0.62, p < 0.0001) (I² = 41%) compared to control, however, no significant results were found for GPE on control of depressive or manic symptoms. No significant results were found for GCBT in all outcomes. Conclusion: This meta-analysis provides some evidence that GPE could be an efficacious treatment as an adjunct to treatment-as-usual in reducing the relapse rates of patients with bipolar disorder.

Interventions for helping people recognise early signs of recurrence in bipolar disorder

This is a protocol for a Cochrane Review (intervention). The objectives are as follows:

To evaluate the effectiveness of EWS plus TAU or EWS plus psychological therapy versus TAU alone or psychological treatment (without EWS) independently on time to recurrence of any bipolar episode and hospitalisation, and other clinically relevant outcome measures. 

To evaluate the effectiveness of intermittent medication used on recognition of EWS without continued mood‐stabilising medication versus TAU involving continued mood‐stabilising medication on time to recurrence of any bipolar episodes.

Use of unstructured intervention in a community-based mental health setting for the recovery of people with depression in Hong Kong: A qualitative assessment

This qualitative evaluation study examined the impact of unstructured intervention on people with depression in a community mental health centre in Hong Kong. In the intervention, service users initiated groups and designed group activities by themselves, with social workers as facilitators. Semi-structured interviews were conducted with service users enrolled in unstructured intervention, their family members, and service providers in 2019. Overall, 32 participants were recruited through purposive sampling. The results revealed that peer interactions helped participants to feel accepted and understood. Participants also acquired experience with emotional coping strategies and practised their interpersonal skills, and by learning new skills from peers, they were able to rebuild their self-esteem and improve their relationships with friends and family. To cater to clients' different needs and concerns, unstructured activities should be diversified. Family and social functioning should also be emphasised in the development of unstructured intervention because the generic skills and knowledge acquired from unstructured activities with peers could help to enhance family relationships, self-confidence, and the ability to manage issues related to working and socialising.

What is the volume, diversity and nature of recent, robust evidence for the use of peer support in health and social care? An evidence and gap map

Background

Peer support interventions involve people drawing on shared personal experience to help one another improve their physical or mental health, or reduce social isolation. If effective, they may also lessen the demand on health and social care services, reducing costs. However, the design and delivery of peer support varies greatly, from the targeted problem or need, the setting and mode of delivery, to the number and content of sessions. Robust evidence is essential for policymakers commissioning peer support and practitioners delivering services in health care and community settings. This map draws together evidence on different types of peer support to support the design and delivery of interventions.

Objectives

The aim of this map was to provide an overview of the volume, diversity and nature of recent, high quality evidence on the effectiveness and cost-effectiveness of the use of peer support in health and social care.

Search Methods

We searched MEDLINE, seven further bibliographic databases, and Epistemonikos for systematic reviews (in October 2020), randomised controlled trials (in March 2021) and economic evaluations (in May 2021) on the effectiveness of peer support interventions in health and social care. We also conducted searches of Google Scholar, two trial registers, PROSPERO, and completed citation chasing on included studies.

Selection Criteria

Systematic reviews, randomised controlled trials and economic evaluations were included in the map. Included studies focused on adult populations with a defined health or social care need, were conducted in high-income countries, and published since 2015. Any measure of effectiveness was included, as was any form of peer support providing the peer had shared experience with the participant and a formalised role.

Data Collection and Analysis

Data were extracted on the type of peer support intervention and outcomes assessed in included studies. Standardised tools were used to assess study quality for all studies: assessing the methodological quality of systematic reviews 2 for systematic reviews; Cochrane risk of bias tool for randomised controlled trials; and consensus health economic criteria list for economic evaluations.

Main Results

We included 91 studies: 32 systematic reviews; 52 randomised controlled trials; and 7 economic evaluations. Whilst most included systematic reviews and economic evaluations were assessed to be of low or medium quality, the majority of randomised controlled trials were of higher quality. There were concentrations of evidence relating to different types of peer support, including education, psychological support, self-care/self-management and social support. Populations with long-term health conditions were most commonly studied. The majority of studies measured health-related indicators as outcomes; few studies assessed cost-effectiveness. Studies were unevenly distributed geographically, with most being conducted in the USA. Several gaps were evident regarding the delivery of peer support, particularly the integration of peers and professionals in delivering support and interventions of longer duration.

Authors' Conclusions

Although there is evidence available to inform the commissioning and delivery of peer support in health and social care, there are also clear gaps that need to be addressed to further support provision, particularly regarding cost-effectiveness. The effectiveness of peer support in different countries, with varying health and social care systems, is a priority for future research, as is the integration of peers with professionals in delivering peer support.

Bipolar disorder treatment according to illness trajectory: a systematic review of clinical trials

The current bipolar disorder treatment guidelines focus mainly on the prevention of recurrence and stabilization of acute mood episodes while neglecting outcomes related to the longitudinal course of illness. We systematically reviewed studies that assess the impact of disease progression in the treatment of patients with bipolar disorder. We searched PubMed, Embase, and Web of Science for clinical trials that moderated treatment effects by number of previous episodes, disease length, or a clinical staging model. We retrieved 6,156 potential abstracts. After deduplication, 5,376 were screened and eight studies met inclusion criteria. Seven trials moderated results by number of prior episodes, and one of those also used a measure of disease length. One trial used a clinical staging model and yielded informing results. Only three studies evaluated pharmacological interventions, the other five assessing psychotherapeutic modalities. Most of the studies were post-hoc analysis of clinical trials not primarily aimed at studying variables associated with illness trajectory. Overall, a loss of efficacy was found according to clinical progression, which supports early intervention. Tailored recommendations according to disease stages cannot be made. Furthermore, we identified methodological weaknesses and strengths in this subfield of research, suggesting the use of clinical staging models for future studies.

Is cognitive behaviour therapy applicable to individuals diagnosed with bipolar depression or suboptimal mood stabilizer treatment: a secondary analysis of a large pragmatic effectiveness trial

Background

Efficacy trials of medications and/or psychological interventions for bipolar disorders (BD) aim to recruit homogenous samples of patients who are euthymic and such populations show high levels of adherence to the treatments offered. This study describes a secondary analysis of a large-scale multi-centre pragmatic effectiveness randomized controlled trial (RCT) of cognitive behaviour therapy plus treatment as usual (CBT) or treatment as usual alone (TAU) and explores outcomes in individuals who were: (i) recruited in depressive episodes, or (ii) receiving suboptimal doses of or no mood stabilizers (MS).

Methods

Data were extract on two separate subsamples (out of 253 RCT participants). Sample 1 comprised 67 individuals in a depressive episode (CBT: 34; TAU: 33); Sample 2 comprised 39 individuals receiving suboptimal MS treatment (CBT: 19; TAU: 20). Survival analyses (adjusted for confounding variables) were used to explore recovery in Sample 1 and relapse in Sample 2.

Results

In Sample 1 (individuals with depression), Cox proportional hazards regression model revealed that the median time to recovery was significantly shorter in the CBT group (10 weeks; 95% confidence intervals (CI) 8, 17) compared to the TAU group (17 weeks; 95% CI 9, 30) [Adjusted Hazard Ratio (HR) 1.89; 95% CI 1.04, 3.4; p < 0.035]. In Sample 2 (suboptimal MS), the median time to any relapse was significantly longer in the CBT group compared to the TAU group (~ 35 versus ~ 20 weeks; Adjusted HR 2.01; 95% CI 1.01, 3.96; p < 0.05) with the difference in survival time to first depressive relapse also reaching statistical significance (X² = 14.23, df 6, p 0.027).

Conclusions

Adjunctive use of CBT appears to have benefits for individuals diagnosed with BD who are highly representative of the patients seen in routine clinical practice, but often excluded from efficacy RCTs. However, as this is a secondary analysis of 42% of the original RCT sample, it is important to replicate these findings in independent larger scale studies specifically designed for purpose.

Do psychological interventions reduce symptoms of depression for patients with bipolar I or II disorder? A meta-analysis

BACKGROUND

Psychological therapies may play an important role in the treatment of bipolar disorders. Several meta-analyses that examine the effectiveness of psychotherapies for patients with bipolar disorder include conclusions about the impact upon bipolar depression. However, these tend not to consider differences in depression outcome depending upon whether the therapy primarily targets acute depression, nor severity of baseline depression. This may affect the conclusions drawn about the effectiveness of these therapies for acute bipolar depression treatment.

OBJECTIVES

This meta-analysis explored the effectiveness of psychological therapies in reducing bipolar depression, in particular examining whether: (1) the effect of therapy is greater when baseline depressive symptoms are more severe, and (2) the effect of therapy is greater when the primary focus of the therapy is the treatment of acute bipolar depression?

DATA SOURCES

A systematic search was conducted using the following electronic databases; Cochrane Controlled Register of Trials (1996), MEDLINE (1966 onwards), EMBASE (1980 onwards), PsycINFO (1974 onwards), Scopus, Web of Science and Clinical Trials Registries (listed at:https://www.hhs.gov/ohrp/international/clinical-trial-registries/index.html).

ELIGIBILITY CRITERIA

Eligible studies were randomized controlled trials evaluating a psychological intervention for adults diagnosed with Bipolar I or II disorder. The comparators were usual care, wait-list, placebo, active treatment control. Post-treatment depression status was required to be measured continuously using a validated self- or observer- report measure, or categorically by a validated diagnostic instrument or clinical diagnosis by a suitably qualified person.

DATA EXTRACTION AND SYNTHESIS

Titles and abstracts were screened, followed by full texts. Two reviewers conducted each stage until agreement was reached, and both independently extracted study information. Means, standard deviations (SDs) and number of participants were retrieved from articles and used to perform a meta-analysis. The primary outcome was depressive symptom score.

RESULTS

The database search identified 6388 studies. After removing the duplicates, 3298 studies remained, of which, 28 studies were included in the qualitative review and 22 in the meta-analysis. Effect sizes range from -1.99 [-2.50, -1.49] to 0.89 [-0.12, 1.90]. There was low quality evidence of a significant effect on symptoms of depression for cognitive behavioral therapy and dialectical behavior therapy. Trials of psychoeducation, mindfulness-based therapy, family therapy and interpersonal and social rhythm therapy showed no evidence of any effect on depression. We found no significant relationship between baseline depression score and depression outcome post-treatment when we controlled for therapy type and comparator. The result also showed that the effect sizes for studies targeting acute depression to be tightly clustered around a small overall effect size.

CONCLUSIONS

Some psychological therapies may reduce acute bipolar depression although this conclusion should be viewed with caution given the low quality of evidence. More research using similar therapy types and comparators is needed to better understand the relationship between depression status at baseline and outcome.

Psychoeducation in bipolar disorder: A systematic review

BACKGROUND

Bipolar disorder (BD) is a severe psychiatric disorder characterized by mood swings. Psychosocial interventions, such as psychoeducation, play an essential role in promoting social rehabilitation and improving pharmacological treatment.

AIM

To investigate the role of psychoeducation in BD.

METHODS

A systematic review of original studies regarding psychoeducation interventions in patients with BD and their relatives was developed. A systematic literature search was performed using the Medline, Scopus, and Lilacs databases. No review articles or qualitative studies were included in the analysis. There were no date restriction criteria, and studies published up to April 2021 were included.

RESULTS

A total of forty-seven studies were selected for this review. Thirty-eight studies included patients, and nine included family members. Psychoeducation of patients and family members was associated with a lower number of new mood episodes and a reduction in number and length of stay of hospitalizations. Psychoeducational interventions with patients are associated with improved adherence to drug treatment. The strategies studied in patients and family members do not interfere with the severity of symptoms of mania or depression or with the patient's quality of life or functionality. Psychoeducational interventions with family members do not alter patients' adherence to pharmacotherapy.

CONCLUSION

Psychoeducation as an adjunct strategy to pharmacotherapy in the treatment of BD leads to a reduction in the frequency of new mood episodes, length of hospital stay and adherence to drug therapy.

Development and Structures of Trialogue for Bipolar Disorders in Germany and Guidelines of the German Society for Bipolar Disorders

The German concept of a trialogue in medicine is at its best a cooperation between patients, relatives, and professionals as partners on equal footing. Prerequisites, and also the aim of the trialogue, are mutual respect, an open attitude from professionals, and self-confidence from patients and relatives. The expertise of each of these groups is to be strengthened through the trialogue and should benefit all. Trialogue cooperation brings about a change of perspective and promotes mutual understanding. By establishing a therapeutic relationship on equal footing with the patient with involvement of their relatives, individual and family resources can be better utilized, professional assistance can be designed to better meet the patient’s needs, and acceptance of and commitment to treatment can be increased. In addition, early symptoms and new phases of the disease can be recognized earlier and adequate treatment can be initiated more quickly. A favorable course of the disease is thus more likely, and relapses are less likely to present. The use of peers has proven to be quite helpful. The consistently trialogue structure within the German Society for Bipolar Disorder (Deutsche Gesellschaft für Bipolare Störungen e.V./DGBS: Heinrich-Hoffmann-Straße 10, 60528 Frankfurt am Main) as a medical society enables further development of the trialogue on many levels, for example, the drafting and updating of the German guidelines for bipolar disorder with the trialogue in mind.

Changing practice: assessing attitudes toward a NICE-informed collaborative treatment pathway for bipolar disorder

BACKGROUND

Bipolar disorder is a chronic mental health condition, which can result in functional impairment despite medication. A large evidence base supports use of psychological therapies and structured care in the treatment of mood disorders, but these are rarely implemented. e-Pathways are digital structures that inform and record patient progress through a healthcare system, although these have not yet been used for bipolar disorder.

AIMS

To assess the perceived benefits and costs associated with implementing a collaborative NICE-informed e-pathway for bipolar disorder.

METHOD

Healthcare professionals and people with bipolar disorder attended a workshop to share feedback on e-pathways. Data were collected through questionnaires (n = 26) and transcription of a focus group, analysed qualitatively by a framework analysis.

RESULTS

Patients and healthcare professionals welcomed the development of an e-pathway for bipolar disorder. There were five elements to the framework: quality and delivery of care, patient-clinician collaboration, flexibility and adaptability, impact on staff and impact on healthcare services.

CONCLUSIONS

Identification of benefits and costs ensures that future development of e-pathways addresses concerns of healthcare professionals and people with bipolar disorder, which would be essential for successful implementation. Recommendations for this development include making e-pathways less complicated for patients, ensuring sufficient training and ensuring clinicians do not feel their skills become invalidated. Limitations of the study, and directions for future research, are discussed.

Efficacy of Phase 1 of Life Goals Programme on symptom reduction and mood stability for bipolar disorder

BACKGROUND

Life Goals Programme (LGP) was developed as a psychological intervention for bipolar disorder, with its structured 6-session psychoeducation phase (Phase 1) targeting understanding of the disorder, medication adherence, early warning signs, and coping with symptoms and triggers. The present study tested the efficacy of Phase 1 of the LGP on symptom recovery and moment-by-moment mood stability, as well as medication adherence and quality of life.

METHODS

Adults with bipolar disorder were randomly allocated to the LGP condition (six weekly group sessions) or the waitlist condition (six weeks of standard care, followed by the same LGP intervention). Participants were assessed before and after treatment, and at 6-month follow up. Waitlist participants were additionally assessed at baseline. Assessment included a clinical interview (SCID, MADRS, YMRS, and HAM-A), self-reported questionnaires, and 6-day experience sampling assessment on a mobile device.

RESULTS

64 out-patients with bipolar disorder (44 Bipolar I and 20 Bipolar II subtypes) participated in this study. LGP was well received and attended. Following LGP, there were significant improvements in knowledge about illness and level of anxiety, which were of large effect sizes and sustained at 6-month follow-up. Experience sampling assessment revealed small but significant improvements in moment-by-moment mood stability. Improvement in medication adherence was significant at 6 months and was of a moderate-to-large effect size. Changes in anxiety and mood stability were significantly greater following LGP than standard care.

LIMITATIONS

Our results warrant further testing against active control.

CONCLUSIONS

There was a robust improvement in emotional regulation following the 6-week LGP.

Psychological factors in personal and clinical recovery in bipolar disorder

BACKGROUND

Research into bipolar disorder (BD) has primarily focused upon clinical recovery (CR), i.e. symptom reduction, and overlooked personally meaningful recovery outcomes emphasized by service users. Personal recovery (PR) has been a major focus in the formulation of mental health policies and guidelines, and yet, research into factors influencing PR in BD is in its infancy.

METHODS

This study compared psychological associates of concurrent PR and CR, and determined psychological factors in PR prospectively at 6 months.

RESULTS

107 participants completed baseline assessments, of whom 84% completed follow-up at 6 months. Controlling for potential confounders, multiple linear and ordinal regression models showed that some psychological factors underpinned both CR and PR at baseline: worse PR and CR outcomes were associated with higher negative self-dispositional appraisals and dysfunctional attitudes. Better PR, but worse CR ([hypo]mania related) were associated with higher adaptive coping. Additionally, better PR (but not CR) was associated with higher concurrent risk taking at baseline and predicted at follow-up by higher levels of baseline rumination. Better CR ([hypo]mania related), but not PR, was associated with lower impulsivity, but higher BAS processes.

LIMITATIONS

Psychological and clinical factors were not measured at follow up and may have changed over time. Participants were a convenience sample.

CONCLUSIONS

Understanding psychological factors driving recovery in BD is essential for refining the conceptual framework of PR, and informing psychological models and related interventions for BD. The identified differences in psychological factors highlight the importance of more individualised, PR focused therapeutic approaches.

The influence of stage of illness on functional outcomes after psychological treatment in bipolar disorder: A systematic review

OBJECTIVES

The aim of this study was to advance understanding of stage of illness in bipolar disorder (BD), by interrogating the literature for evidence of an influence of stage of illness on functional (ie non-symptom) outcomes following psychosocial intervention.

METHODS

A systematic literature search following PRISMA guidelines was conducted to identify empirical studies of psychosocial interventions for established BD. To investigate stage as a predictor of three functional outcomes (general/social functioning, cognitive functioning and quality of life [QoL]), study samples were dichotomised into earlier and later stage using proxy measures identified in existing staging models. Findings were integrated using data-based convergent synthesis.

RESULTS

A total of 88 analyses from 62 studies were identified. Synthesis across studies suggested that psychosocial intervention was more likely to be effective for general functioning outcomes earlier in the course of established BD. No stage-related differences were found for cognitive or QoL outcomes. Exploratory investigations found some evidence of an interaction between specific intervention type and stage of illness in predicting outcomes.

CONCLUSIONS

A novel systematic review provided preliminary evidence that benefits general/social functioning may be more pronounced in earlier versus later stages of established BD. The review also generated hypotheses about a potential three-way interaction, whereby specific psychosocial interventions may be best placed to target functional outcomes in earlier versus later stage BD. The strength of conclusions is limited by the overall low-quality and significant heterogeneity of studies. Further research is urgently required to understand the impact of illness stage on the effectiveness of psychosocial interventions.

A prospective longitudinal study searching for predictors of response to group psychoeducation in bipolar disorder

BACKGROUND

The efficacy of adjunctive group psychoeducation in bipolar disorder has been proven although treatment response differ among individuals. The aim of this study was to characterize responders and non-responders to group psychoeducation in order to identify baseline variables that could predict treatment response.

METHODS

The sample was composed of 103 medicated euthymic patients with bipolar disorder referred to 21 sessions of group psychoeducation (6 months). Sociodemographic and clinical variables, temperament, circadian rhythms, BDNF, cognitive and psychosocial functioning were collected. At the 18-month endpoint, the patients were split in two groups on the basis of having suffered any recurrence. Significant group differences were included in a logistic regression analysis.

RESULTS

Ninety patients out of 103 engaged in group psychoeducation, 47 of whom (52.2%) responded to psychoeducation and 43 (47.8%) did not. Recurrences occurred more often in the follow-up, the most common being depression. Responders and non-responders differed in gender, age at diagnosis, latency of diagnosis, temperament, attention composite score and BDNF. Lower age at diagnosis of bipolar disorder, lower cyclothimic temperament scores and being male -which was associated with bipolar type I and a trend to more previous manic episodes- were significantly related to a better response to psychoeducation in the regression analysis.

LIMITATIONS

No control group.

CONCLUSIONS

This study identifies age at diagnosis as a significant modifiable risk factor of treatment response, highlighting the need for early identification of bipolar disorder. Existing programs should be adjusted to the characteristics of specific subpopulations in the framework of a personalized approach.

A multi-center naturalistic study of a newly designed 12-sessions group psychoeducation program for patients with bipolar disorder and their caregivers

Background

Psychoeducation (PE) for bipolar disorder (BD) has a first-line recommendation for the maintenance treatment phase of BD. Formats vary greatly in the number of sessions, whether offered individually or in a group, and with or without caregivers attending. Due to a large variation in formats in the Netherlands, a new program was developed and implemented in 17 outpatient clinics throughout the country. The current study investigated the feasibility of a newly developed 12-sessions PE group program for patients with BD and their caregivers in routine outpatient practice and additionally explored its effectiveness.

Methods

Participants in the study were 108 patients diagnosed with BD, 88 caregivers and 35 course leaders. Feasibility and acceptance of the program were investigated by measures of attendance, and evaluative questionnaires after session 12. Preliminary treatment effects were investigated by pre- and post-measures on mood symptoms, attitudes towards BD and its treatment, levels of self-management, and levels of expressed emotion.

Results

There was a high degree of satisfaction with the current program as reported by patients, caregivers, and course leaders. The average attendance was high and 83% of the patients and 75% of the caregivers completed the program. Analyses of treatment effects suggest positive effects on depressive symptoms and self-management in patients, and lower EE as experienced by caregivers.

Conclusions

This compact 12-sessions psychoeducation group program showed good feasibility and was well accepted by patients, caregivers, and course leaders. Preliminary effects on measures of self-management, expressed emotions, and depressive symptoms were promising. After its introduction it has been widely implemented in mental health institutions throughout the Netherlands.

Psychosocial therapies in severe mental illness: update on evidence and recommendations

PURPOSE OF REVIEW

To provide an overview of the update of the evidence-based and consensus-based German S3 guideline on psychosocial therapies for severe mental illnesses (SMI), with particular attention to current developments and future research tasks.

RECENT FINDINGS

There has been a significant increase in studies on the effectiveness of psychosocial interventions in treatment of people with SMI. In the guideline a distinction is made between system-level interventions (e.g. multidisciplinary team-based psychiatric community care) and single-handed (nonteam-based) interventions (e.g. psychoeducation). Furthermore, principles of treatment (e.g. recovery-orientation) and self-help interventions (e.g. peer support) are addressed. The update of the guideline includes 33 recommendations and 12 statements. Compared with the first edition, there were upgrades in the recommendation of Supported Employment (A) and Supported Housing (A). Interventions such as peer support (B) and lifestyle interventions (A) were included for the first time. Developments are discussed in the context of most recent literature. Areas for further research are highlighted and fields for next updates such as antistigma interventions and supported parenting were identified.

SUMMARY

The present guideline offers an important opportunity to further improve health services for people with SMI. However, guideline implementation is challenging.

Psychoeducation for bipolar disorder and risk of recurrence and hospitalization - a within-individual analysis using registry data

BACKGROUND

The efficacy of psychoeducation for bipolar disorder has been demonstrated in clinical trials, but it is not known if the results translate into effectiveness in routine clinical practice. The aim was to determine the effectiveness of psychoeducation for bipolar disorder in a routine clinical setting.

METHOD

We identified 2819 patients with at least three registrations in the Swedish Quality Assurance Register for Bipolar Disorder. Among those, 402 had not been exposed to psychoeducation at the first visit, but received psychoeducation during any of the following registrations. Using within-individual analyses, the risk of recurrence after having received psychoeducation was compared with the risk prior to psychoeducation.

RESULTS

In adjusted within-individuals comparisons, periods after psychoeducation was associated with decreased risks of any recurrence [odds ratio (OR) 0.57, 95% CI 0.42-0.78], (hypo-)manic or mixed episodes (OR 0.54, 95% CI 0.39-0.76), depressive episodes (OR 0.63, 95% CI 0.47-0.86), and inpatient care (OR 0.54, 95% CI 0.33-0.86) relative to periods prior to psychoeducation. There was no association with rates of involuntary sectioning or suicide attempts.

CONCLUSIONS

The results suggest that psychoeducation for bipolar disorder reduces the risk of mood episodes and inpatient care also when implemented in routine clinical practice.

Individual experiences of psychological-based interventions for bipolar disorder: A systematic review and thematic synthesis

PURPOSE

To conduct a thematic synthesis to evaluate qualitative studies exploring individuals' experiences of psychological-based interventions for bipolar disorder (BD).

METHOD

A systematic search of relevant databases (Web of Science, PsycINFO, MEDLINE, CINAHL) was conducted using predefined search terms related to 'Bipolar' 'Qualitative method', 'Psychological-based interventions' and 'Adults'. Studies meeting the inclusion criteria were selected and were then evaluated using established quality appraisal criteria. A thematic synthesis was used to synthesize the findings.

RESULTS

From the thematic synthesis, nine analytical themes were derived from the 10 identified research studies. These were helpful and unhelpful aspects of the intervention, increased knowledge of BD, mood recognition, control of moods, change of perspective, mood stability, empowerment, improved relationships and lifestyle changes.

CONCLUSIONS

Findings from the review suggest there were characteristics of psychological-based interventions that individuals with BD valued and which helped facilitate areas of positive change, such as feeling empowered and in control of their moods and other aspects of their lives. However, there were also elements that individuals did not find as helpful and therefore reflects the challenge of a one-size-fits-all model or plan of interventions, compared to a wider recognition of the individuals as being the agent of their recovery. Future qualitative research is needed to explore individual experiences across a range of psychological interventions, in order to further understand the therapeutic processes, which may facilitate recovery.

PRACTITIONER POINTS

Psychological-based interventions for BD need to consider facilitating and measuring empowerment in individuals, rather than focusing just on mood stability. Clinicians with expertise and knowledge in BD should provide timely information to individuals and their families to help increase their understanding of the diagnosis.

Short group psychoeducation followed by daily electronic self-monitoring in the long-term treatment of bipolar disorders: a multicenter, rater-blind, randomized controlled trial

Background

Despite various pharmacological and psychological treatment interventions, bipolar disorders rank among the leading causes of global disease burden. Group psychoeducation has been demonstrated an effective add-on to pharmacotherapy, but it may be difficult to implement in practice depending on the clinical setting and available human resources.

Methods

Multicenter, rater-blind, randomized controlled trial to investigate the efficacy of a new intervention program consisting of an initial 6-week psychoeducation protocol plus a subsequent structured daily computer-based self-charting program (ChronoRecord) over 54 weeks in remitted patients with bipolar disorders. The control condition included non-structured group sessions followed by daily computer-based self-reports (unstructured like a diary). Both groups received treatment-as-usual.

Results

Over 2 years, 41 mood episodes occurred in the experimental group (n = 39) compared to 27 in the control group (n = 34), without reaching statistical significance. Time to recurrence did not significantly differ between the experimental and control group (25% relapsed after 112 and 273 days, respectively). There were no significant group-by-time interactions in mood symptoms, quality of life, self-efficacy expectations or perceived involvement in care.

Conclusions

Six weekly psychoeducational group sessions followed by daily self-monitoring via ChronoRecord for 54 weeks may not be superior to non-structured group meetings followed by unstructured self-reporting. Other psychotherapeutic interventions may be needed to optimize the treatment of patients with bipolar disorders, especially for those at later disease stages.

Evidence-Based Psychotherapies for Bipolar Disorder

Bipolar disorder is a recurrent psychiatric disorder marked by waxing and waning affective symptoms and impairment in functioning. Some of the morbidity and mortality associated with the illness may be reduced with evidence-based psychotherapies (EBPs) along with pharmacotherapy. To enhance clinicians' understanding of which therapy modalities have evidence supporting their use, the authors conducted a systematic literature review to identify randomized controlled trials (RCTs) of psychotherapy for adults with bipolar disorder. A strong evidence base exists for psychoeducation, cognitive-behavioral therapy, family-focused therapy, interpersonal and social rhythm therapy, and peer-support programs. Promising modalities include functional remediation, mindfulness-based cognitive therapy, illness management and recovery, and technology-assisted strategies. RCTs demonstrate a consistent advantage of these psychotherapies plus pharmacotherapy, compared with the use of pharmacotherapy alone. Adjunctive EBPs hasten time to remission, delay time to recurrence, and improve functional outcomes. EBPs play an important role in helping individuals develop skills needed to manage the persistent and lifelong psychosocial, neurocognitive, vocational, and interpersonal consequences of bipolar disorder. Continued efforts to improve the effectiveness of EBPs for adults with bipolar disorder are warranted.

Psychosocial Interventions for Bipolar II Disorder

Bipolar II disorder causes significant suffering among patients and their families, some of which may be alleviated by psychotherapy alone or as an adjunct to pharmacotherapy. Psychotherapies may be more effective if modified to meet the specific needs of patients with bipolar II disorder.

Psychoeducation for psychiatric inpatients following remission of a manic episode in bipolar I disorder: A randomized controlled trial

OBJECTIVE

The aim of the present study was to evaluate the effectiveness of psychoeducation for bipolar I inpatients following remission of a manic episode in a Chinese population.

METHOD

The study recruited currently medicated bipolar I patients, aged 18-60 years, who were in remission from a manic episode, as determined using the Diagnostic and Statistical Manual of Mental Disorders Fifth Edition (DSM-5). Patients were randomized (1:1) to either eight sessions of group-based psychoeducation (active treatment group) or regular free discussions (control group). The primary outcomes were the rates of any type of recurrence and rehospitalization following treatment. The secondary outcomes were changes in mood symptoms, medication adherence, global functioning, as well as treatment response (as measured using the Clinical Global Impression scale). Subjects were assessed at baseline and then at 2 weeks, and 1, 2, 3, 5, 7, 9, and 12 months following treatment.

RESULTS

At 1 year, patients receiving the psychoeducation treatment demonstrated significantly less recurrence. Those in the treatment group also showed a significant reduction in mania recurrence but not depressive recurrence, and psychoeducation increased time to remission. Notably, lower rates of rehospitalization were found in the active treatment group. Those receiving the psychoeducation treatment also revealed higher change from baseline on measures of depression (17-item Hamilton Rating Scale for Depression), mania (Young Mania Rating Scale), global functioning (Clinical Global Impression-severity scale and World Health Organization Disability Assessment Schedule) (P<.05). However, there were no significant group differences for the medication adherence scores.

CONCLUSION

This preliminary evidence suggests that short, group-based psychoeducation benefits currently medicated inpatients following the remission of mania in bipolar I disorder. This intervention warrants further investigation, especially in other Chinese populations. If future studies confirm its benefits, group-based psychoeducation could be incorporated into routine psychiatric inpatient care for bipolar patients in China.

The Long-Term Effectiveness of Psychoeducation for Bipolar Disorders in Mental Health Services. A 4-Year Follow-Up Study

Aims: The aims of the present study were to assess: the effectiveness of psychoeducation in mental health service (MHSs) in terms of time to first hospitalization during 4-year follow-up; the number and the days of hospitalizations, and the number of people hospitalized at 4-year follow-up; and variables associated with better outcome in BD patients. Methods: This is a controlled study involving an experimental group (N = 57) and a control group (N = 52). The treatment phase consists of 21 weeks, in which all participants received TAU, while the experimental group received additional psychoeducation. Results: The survival analysis showed significant differences in terms of time to first hospitalization of up to 4-year follow-up: the patients in the psychoeducation group showed a longer time free from hospitalizations than the control group. Concerning the predictors of time to first hospitalization, the only factor that showed a trend to statistical significance was psychoeducation. Conclusions: This is one of few studies assessing the long-term effectiveness of psychoeducation in a naturalistic setting. The data confirm that psychoeducation can impact illness course, in terms of longer time free from hospitalizations. Trial registration: ISRCTN17827459.

Areas of uncertainties and unmet needs in bipolar disorders: clinical and research perspectives

This Review discusses crucial areas related to the identification, clinical presentation, course, and therapeutic management of bipolar disorder, a major psychiatric illness. Bipolar disorder is often misdiagnosed, leading to inappropriate, inadequate, or delayed treatment. Even when bipolar disorder is successfully diagnosed, its clinical management presents several major challenges, including how best to optimise treatment for an individual patient, and how to balance the benefits and risks of polypharmacy. We discuss the major unmet needs in the diagnosis and management of bipolar disorder in this Review, including improvement of adequate recognition and intervention in at-risk and early-disease stages, identification of reliable warning signs and prevention of relapses in unstable and rapid cycling patients, treatment of refractory depression, and prevention of suicide. Taken together, there are several promising opportunities for improving treatment of bipolar disorder to deliver medical care that is more personalised.

Canadian Network for Mood and Anxiety Treatments (CANMAT) and International Society for Bipolar Disorders (ISBD) 2018 guidelines for the management of patients with bipolar disorder

The Canadian Network for Mood and Anxiety Treatments (CANMAT) previously published treatment guidelines for bipolar disorder in 2005, along with international commentaries and subsequent updates in 2007, 2009, and 2013. The last two updates were published in collaboration with the International Society for Bipolar Disorders (ISBD). These 2018 CANMAT and ISBD Bipolar Treatment Guidelines represent the significant advances in the field since the last full edition was published in 2005, including updates to diagnosis and management as well as new research into pharmacological and psychological treatments. These advances have been translated into clear and easy to use recommendations for first, second, and third- line treatments, with consideration given to levels of evidence for efficacy, clinical support based on experience, and consensus ratings of safety, tolerability, and treatment-emergent switch risk. New to these guidelines, hierarchical rankings were created for first and second- line treatments recommended for acute mania, acute depression, and maintenance treatment in bipolar I disorder. Created by considering the impact of each treatment across all phases of illness, this hierarchy will further assist clinicians in making evidence-based treatment decisions. Lithium, quetiapine, divalproex, asenapine, aripiprazole, paliperidone, risperidone, and cariprazine alone or in combination are recommended as first-line treatments for acute mania. First-line options for bipolar I depression include quetiapine, lurasidone plus lithium or divalproex, lithium, lamotrigine, lurasidone, or adjunctive lamotrigine. While medications that have been shown to be effective for the acute phase should generally be continued for the maintenance phase in bipolar I disorder, there are some exceptions (such as with antidepressants); and available data suggest that lithium, quetiapine, divalproex, lamotrigine, asenapine, and aripiprazole monotherapy or combination treatments should be considered first-line for those initiating or switching treatment during the maintenance phase. In addition to addressing issues in bipolar I disorder, these guidelines also provide an overview of, and recommendations for, clinical management of bipolar II disorder, as well as advice on specific populations, such as women at various stages of the reproductive cycle, children and adolescents, and older adults. There are also discussions on the impact of specific psychiatric and medical comorbidities such as substance use, anxiety, and metabolic disorders. Finally, an overview of issues related to safety and monitoring is provided. The CANMAT and ISBD groups hope that these guidelines become a valuable tool for practitioners across the globe.

A systematic review of immunosuppressant adherence interventions in transplant recipients: Decoding the streetlight effect

Non-adherence to immunosuppressant medications is an important risk factor for graft dysfunction. To evaluate the effectiveness of adherence-enhancing interventions, we reviewed adherence intervention studies in solid organ transplant recipients (all ages). Using the following databases: PsycINFO, PubMed, Scopus, and ScienceDirect, we identified 41 eligible studies. Only three non-randomized trials showed a possible positive effect on objective indicators of transplant outcomes (such as rejection, liver enzyme levels, kidney function). None of the 21 RCTs showed an improvement in transplant outcomes. Three studies showed a higher rate of adverse events in the intervention group as compared with controls, although this may be related to ascertainment bias. Improvement in adherence as measured indirectly (eg, with electronic monitoring devices) was not aligned with effects on transplant outcomes. We conclude that adherence interventions, to date, have largely been ineffective in improving transplant outcomes. To improve this track record, intervention efforts may wish to concentrate on non-adherent patients (rather than use convenience sampling, which excludes many of the patients who need the intervention), use direct measures of adherence to guide the interventions, and employ strategies that are intensive and yet engaging enough to ensure that non-adherent patients are able to participate.

A study of the real-world effectiveness of group psychoeducation for bipolar disorders: Is change in illness perception a key mediator of benefit?

BACKGROUND

Findings from efficacy trials of group psychoeducation (PE) for bipolar disorders (BD) led to its inclusion in evidence-based guidelines as a first-line mandatory treatment. However, pragmatic trials and observational studies are needed to determine its real-world effectiveness, impact on outcomes deemed important to patients and to clarify potential mediators of any benefits.

METHODS

Individuals with BD were offered the opportunity to participate in 20h of PE and asked to complete pre- and post-intervention ratings of symptoms, knowledge about BD, medication adherence, and illness perception. A priori, two key patient outcomes were identified (social functioning and self-esteem); sample attrition due to dropout or relapse was recorded.

RESULTS

Of 156 individuals who completed the pre-PE assessments, 103 completed the program and post-PE assessments. Only 4 of 53 dropouts were associated with BD relapse. Post-intervention, the PE completers demonstrated a statistically significant improvement in social functioning (p = 0.003, Effect Size (ES) = 0.26) and a trend towards improved self-esteem (ES = 0.14). Whilst there were significant changes in medication adherence (p = 0.002, ES = 0.28), knowledge of BD (p < 0.001, ES = 1.20), and illness perception (p < 0.001, ES = -0.37), mediational analysis demonstrated that only change in illness perception was associated to change in functioning (p=0.03) with no contribution from changes in knowledge of BD or medication adherence.

CONCLUSIONS

In real-world settings, over 60% individuals completed 10-session course of PE. After controlling for demography and baseline clinical state, change in illness perception, rather than change in knowledge or medication adherence, emerged as a potential mediator of some benefits of PE.

Public involvement in public health research

Purpose

The purpose of this paper is to examine the progress in public and patient involvement (PPI) in public health research, and identify the relevant problems and solutions.

Design/methodology/approach

To explore the advantages and drawbacks of PPI in health research, drawing on studies which have looked at the barriers to effective PPI, as well as the benefits to all parties.

Findings

Guidelines have emerged from recent research for the process of PPI throughout a project; however different schemes for PPI will apply, depending on the context.

Research limitations/implications

There are not many well-researched studies into PPI in this area. A frequent limitation in research projects is that there is not sufficient provision for PPI. The implication is that more time and funding should be made available for well-planned PPI.

Practical implications

Researchers need to find more ways for involvement, as well as optimising current methods.

Social implications

The growth of PPI has opened up channels of communication and developed new roles for people in research, who would not otherwise be involved.

Originality/value

The paper draws together a range of studies in an original way, as well as using some unpublished material. It is an area of current interest.

Cost-effectiveness of structured group psychoeducation versus unstructured group support for bipolar disorder: Results from a multi-centre pragmatic randomised controlled trial

BACKGROUND

Bipolar disorder (BD) costs the English economy an estimated £5.2billion/year, largely through incomplete recovery. This analysis estimated the cost-effectiveness of group psychoeducation (PEd), versus group peer support (PS), for treating BD.

METHODS

A 96-week pragmatic randomised controlled trial (RCT), conducted in NHS primary care. The primary analysis compared PEd with PS, using multiple imputed datasets for missing values. An economic model was used to compare PEd with treatment as usual (TAU). The perspective was Health and Personal Social Services.

RESULTS

Participants receiving PEd (n=153) used more (costly) health-related resources than PS (n=151) (net cost per person £1098 (95% CI, £252-£1943)), with a quality-adjusted life year (QALY) gain of 0.023 (95% CI, 0.001-0.056). The cost per QALY gained was £47,739. PEd may be cost-effective (versus PS) if decision makers are willing to pay at least £37,500 per QALY gained. PEd costs £10,765 more than PS to avoid one relapse. The economic model indicates that PEd may be cost-effective versus TAU if it reduces the probability of relapse (by 15%) or reduces the probability of and increases time to relapse (by 10%).

LIMITATIONS

Participants were generally inconsistent in attending treatment sessions and low numbers had complete cost/QALY data. Factors contributing to pervasive uncertainty of the results are discussed.

CONCLUSIONS

This is the first economic evaluation of PEd versus PS in a pragmatic trial. PEd is associated with a modest improvement in health status and higher costs than PS. There is a high level of uncertainty in the data and results.
