Sequential mixed method evaluation of the acceptability, feasibility, and appropriateness of cognitive behavioral therapy for psychosis stepped care

Background

Cognitive Behavioral Therapy for psychosis (CBTp) is recommended by national treatment guidelines yet remains widely inaccessible in the U.S. A stepped care model, favored and feasible for other scarce interventions, may improve access to CBTp.

Methods

We employed an exploratory sequential mixed method design inclusive of two distinct phases to quantitatively evaluate the acceptability, feasibility, and appropriateness of CBTp Stepped Care (CBTp-SC) among practitioners who were trained in low-intensity CBTp (Step 1), Group-Administered CBTp (Step 2), and Formulation-based CBTp (Step 3). In Phase 1, we queried respondents using the Acceptability of Intervention Measure, Intervention Appropriateness Measure, and the Feasibility of Intervention Measure to ascertain perceptions of these leading indicators of implementation success. In Phase 2, we conducted focus groups with CBTp-SC-trained practitioners (n = 10) and administrators (n = 2) from 2 of the 4 Phase 1 study sites to evaluate the theoretical assumptions of stepped care and to better understand key barriers and facilitators.

Results

Forty-six practitioners trained in all three levels of CBTp-SC completed the online survey in Phase 1. All participants were employed by a community mental health agency currently sustaining CBTp-SC. Respondents endorsed high levels of acceptability, feasibility, and appropriateness for the CBTp-SC model. We found evidence to suggest that licensed practitioners and Step 3 practitioners perceived formulation-based CBTp as more appropriate for their clients. In Phase 2, six themes emerged which affirmed the utility of the model for stakeholders, supported stepped care theoretical assumptions, and revealed key areas for improvement.

Conclusions

Early adopters of CBTp-SC in the U.S. perceive it to be acceptable, feasible, and appropriate in community mental health care settings. Practitioners and administrators identified training and implementation barriers, including the importance of organizational readiness, a CBTp coordinator role, and a desire to adapt the intervention. These early findings will facilitate iterative refinement of the stepped care model for U.S. public behavioral health agencies. Additional research is needed to explore perceptions and clinical outcomes among CBTp service users.

Cognitive -behavioral therapy for managing depressive and anxiety symptoms after stroke: a systematic review and meta-analysis

BACKGROUND

Post-stroke anxiety and depression can be disabling and result in impaired recovery. Cognitive-behavioral therapy (CBT) has been demonstrated to be effective for anxiety and depression; however, determining its efficacy among those with stroke is warranted. Our objectives to evaluate CBT for anxiety and depression post-stroke .

METHODS

This review was registered with PROSPERO (REG# CRD42020186324). Medline, PsycInfo, and EMBR Cochrane were used to locate studies published before May 2020, using keywords such as stroke and CBT. A study was included if: (1) interventions were CBT-based, targeting anxiety and/or depression; (2) participants experienced a stroke at least 3 months previous; (3) participants were at least 18 years old. Standardized mean differences ± standard errors and 95% confidence intervals were calculated, and heterogeneity was determined. The Cochrane Risk of Bias tool was used.

RESULTS

The search yielded 563 articles, of which 10 (N = 672) were included;6 were randomized controlled trials. Primary reasons for exclusion included: (1) wrong population (2) insufficient data provided for a meta-analysis; (3) wrongoutcomes. CBT showed large effects on reducing overall anxiety (SMD ± SE: 1.01 ± 0.32, p < .001) and depression (SMD ± SE: 0.95 ± 0.22, p < .000) symptoms at the end of the studies. CBT moderately maintained anxiety (SDM ± SE: 0.779 ± 0.348, p ˂.025) and depression (SDM ± SE: 0.622 ± 0.285, p ˂ .029) scores after 3-months. Limitations included small sample size, limited comparators, and lack of follow-up data.

CONCLUSION

The results of this meta-analysis provide substantial evidence for the use of CBTto manage post-stroke anxiety and depression.

Feasibility, acceptability, and preliminary effectiveness of mindfulness-based interventions for people with recent-onset psychosis: A systematic review

BACKGROUND

Early intervention for psychosis is recommended because the first 5 years beyond the first episode is considered the critical period within which individuals have the most potential to maximize their response to treatment and recovery. Mindfulness-based interventions (MBIs) have been studied extensively in diverse disease groups, but research in people with recent-onset psychosis is still immature.

AIM

This review aims to explore the feasibility, acceptability and summarize any effectiveness data on of the MBIs for people with recent-onset psychosis reported by the study authors.

METHODS

A systematic search of original intervention research studies relevant to the topic published between January 2000 and August 2019 was conducted with 10 databases. Articles published in English with accessible full text were included.

RESULTS

A total of eight studies were included, which reported recruitment rates of between 62.5% and 100%, withdrawal rates between 0% and 37.5% and attendance rates of between 56% and 100%. Participants' qualitative feedback indicated high levels of satisfaction with the MBIs. The intervention approaches adopted in the reviewed studies include mindfulness-based interventions, acceptance and commitment therapy and compassion-based interventions. MBIs have produced promising positive effects on participants' psychiatric and psychosocial outcomes.

CONCLUSION

This review confirms that MBIs are generally feasible and acceptable for people with recent-onset psychosis. The preliminary results suggested the potential effects of MBIs in this area. Fully powered randomized controlled trials are suggested to confirm the effectiveness and exploratory studies to gain greater insight into the active components and mechanism of actions of MBIs for recent-onset psychosis.

A Feasibility Study of the Translation of Cognitive Behaviour Therapy for Psychosis into an Australian Adult Mental Health Clinical Setting

There is evidence that Cognitive Behaviour Therapy for Psychosis (CBTp) is an effective intervention for reducing psychotic symptoms. The recently updated Royal Australian and New Zealand College of Psychiatrists clinical practice guidelines (RANZCP CPG) recommend CBTp for the therapeutic management of schizophrenia and related disorders. Translational research is required to examine how well CBTp can be applied into public mental health services. This feasibility study aimed to provide preliminary evidence on how acceptable, implementable, and adaptable individual or group CBTp may be within a public mental health service in Australia. Twenty-seven participants initially agreed to participate in the study with 16 participants being randomised to either group or individual therapy, 11 starting therapy and 7 completing therapy. The intervention involved approximately 20 h of manualised CBTp. Attendance was higher in the individual therapy. Subjective reports indicated that the therapy was acceptable to all completers. Participants who engaged in individual or group CBTp experienced a similar level of reduction in the severity of hallucinations and delusions. Individual CBTp may be a feasible, acceptable, and effective intervention to include in Australian public mental health services. A pilot trial is now required to provide further evidence for and guidance of how best to translate CBTp protocols to Australian mental health services.

Evidence-Based Psychosocial Treatment for Individuals with Early Psychosis

Coordinated specialty care (CSC) first-episode models are an evidence-based practice in the treatment of first-episode psychosis. Group, individual, and family therapies in CSC aim to help the client and family understand and cope with the experience of psychosis, promote symptomatic and functional recovery and improve quality of life, and support the pursuit of personally meaningful goals of the client. Common elements to these interventions include building a therapeutic alliance, recovery orientation, education, and skills training, which can be directed to a range of targets, including problem-solving, communication, social skills, and social cognition.

Group cognitive behavioural therapy for psychosis in the Asian context: a review of the recent studies

The cardinal symptoms of psychosis include hallucination and delusion, which can be both distressing and disabling. International guidelines recommend cognitive behavioural therapy for psychosis (CBTp) as an adjunctive intervention to medication management. Considering the difficulty in the widespread dissemination of the individual CBTp, group CBTp is an alternative in improving patients' access to psychological intervention. Although it has been found feasible and effective in various studies, systematic review on group CBTp, particularly in Asia, was not identified. Hence, this systematic review tried to examine the recent evidence of group CBTp in Asia in order to shed light on its implementation in routine psychiatric care. A relevant literature search was conducted in three databases (Pubmed, Web of Knowledge, and PsycINFO) during the period from January 2000 to December 2018. A total of 114 journal articles were identified. After a full-text review, four studies met our inclusion and exclusion criteria. Despite methodological shortcomings, positive results were found in terms of improvements on psychotic symptoms, functioning, and quality-of-life. These encouraging results indicate the need for future research studies with more rigorous methodology, leading to a better understanding on the applicability and effectiveness of group CBTp in the Asian context.

Group cognitive behavioural therapy for Chinese patients with psychotic disorder: A feasibility controlled study

AIM

Evidence for the effectiveness of individual cognitive behavioural therapy for psychosis (CBTp) is promising but evidence for presenting CBTp in a group setting and in the Asian context is limited. The present study is to evaluate the feasibility and effectiveness of Group CBTp in clinical practice.

METHOD

Forty-eight out-patients and day-patients with the schizophrenia spectrum disorders were recruited and randomly assigned to the group CBTp plus treatment as usual (TAU), or psychoeducation group (PsyEdI) plus TAU. Both interventions consisted of 7 consecutive weekly sessions with a booster session 4 weeks after the last session. Patients were assessed on outcome measures such as the Psychotic Symptom Rating Scales (PSYRATS), the Beck Depression Inventory (BDI), a Chinese version of the Beliefs About Voice Questionnaire-Revised version (BAVQ-R), at baseline and after treatment.

RESULTS

Patients received group CBTp (n = 25) showed significantly greater improvement in their delusion compared with those receiving PsyEdI (n = 23). Nearly 61% of patients in the group CBTp showed at least 50% reduction on their score of delusion in the PSYRATS. Group CBTp was also found to be effective in reducing patients' dysfunctional beliefs towards voices, especially in the subscale of benevolence and omnipotence, their conviction on delusion, as well as their distress from positive psychotic symptoms.

CONCLUSION

Group CBTp can be an effective adjunctive psychological intervention in improving positive psychotic experiences among people with persistent psychotic symptoms, and can be applied in routine clinical practice.

Psychological interventions on a specialist Early Intervention Inpatient Unit: An opportunity to engage?

BACKGROUND

This study explored engagement with psychology on a specialist early intervention psychosis inpatient unit, with a focus on whether demographics or admission factors impacted on engagement.

METHOD

This was a retrospective cohort study using data extracted from patient notes for all service users who were admitted to an Early Intervention ward during a specified 6-month period. One hundred and one records were identified.

RESULTS

Sixty-eight (67.3%) of the service users engaged in psychological therapy, 45.6% (n = 47) attended psychology groups and 58.4% (n = 59) engaged in individual psychology sessions. Service users admitted to the ward voluntarily were more likely to engage in individual psychology sessions in comparison to those admitted under section of the mental health act (β = -0.270, P < .005). Length of admission predicted engagement with groups (β = 0.38, P < .001) and individual psychology sessions (β = 0.408, P < .001). Ethnicity, gender and number of admissions did not predict engagement in psychology.

CONCLUSIONS

Psychological interventions are acceptable on a specialist early intervention psychosis inpatient ward and offer an opportunity to engage service users. Engagement was not predicted by demographic factors typically seen in community settings. Implications arising from these differences are discussed.

Canadian Treatment Guidelines on Psychosocial Treatment of Schizophrenia in Children and Youth

OBJECTIVE

A panel of experts, including researchers, clinicians and people with lived experience, was brought together to develop the new Canadian schizophrenia guidelines for the psychosocial treatment of children and youth with schizophrenia or psychotic disorders.

METHOD

The ADAPTE process, which relies on adapting existing high-quality guidelines, was used. Existing guidelines for children and youth (mostly from the National Institute for Health and Care Excellence [NICE]), as well as CPA adult guidelines, were reviewed and discussed in terms of their adaptability to the Canadian context and their level of recommendation for children and youth. New treatments were also considered when recent meta-analyses suggested their usefulness.

RESULTS

The children and youth psychosocial guidelines include many cross-sectional recommendations in terms of clinical and interpersonal skills needed to work with this clientele, setting and collaboration issues and needed adaptations for specific subpopulations. In terms of specific treatments, the treatments most strongly recommended are family intervention and cognitive behavior therapy. Also recommended, although with different degrees of support, are supported employment/supported education programs, patient education, cognitive remediation, and social skills training. Novel and upcoming psychosocial treatments are also briefly discussed.

CONCLUSION

These novel Canadian guidelines for the psychosocial treatment of children and youth with schizophrenia or psychotic disorders report evidence-based treatments as well as important considerations for providers who work with this clientele. More studies with children and youth with schizophrenia and psychotic disorders are warranted. If followed, these guidelines should facilitate the recovery of children and youth with schizophrenia or psychotic disorders as well as the recovery of their families.

Canadian Treatment Guidelines on Psychosocial Treatment of Schizophrenia in Adults

OBJECTIVE

It is generally recognised that psychosocial interventions are essential components of the effective treatment of schizophrenia in adults. A considerable body of research is being published regarding the effectiveness of such interventions. In the current article, we derive recommendations reflecting the current state of evidence for their effectiveness.

METHODS

Recommendations were formulated on the basis of a review of relevant guidelines, particularly those formulated by the Scottish Intercollegiate Guideline Network (SIGN) and National Institute for Health and Care Excellence (NICE).

RESULTS

There is evidence strongly supporting the use of family interventions, supported employment programs, and cognitive-behavioural therapy. There are also reasons to recommend the use of cognitive remediation, social skills training, and life skills training under specified circumstances. It is important that all patients and families be provided with education about the nature of schizophrenia and its treatment. Several recent innovative psychosocial approaches to treatment are awaiting more thorough evaluation.

CONCLUSIONS

There continues to be strong evidence for the effectiveness of several psychosocial interventions in improving outcomes for adults with schizophrenia. In the past decade, innovative interventions have been described, several of which are the subject of ongoing evaluative research.

Cognitive behavioral therapy in 22q11.2 microdeletion with psychotic symptoms: What do we learn from schizophrenia?

The 22q11.2 deletion syndrome (22q11.2DS) is one of the most common microdeletion syndromes, with a widely underestimated prevalence between 1 per 2000 and 1 per 6000. Since childhood, patients with 22q11.2DS are described as having difficulties to initiate and maintain peer relationships. This lack of social skills has been linked to attention deficits/hyperactivity disorder, anxiety and depression. A high incidence of psychosis and positive symptoms is observed in patients with 22q11.2DS and remains correlated with poor social functioning, anxiety and depressive symptoms. Because 22q11.2DS and schizophrenia share several major clinical features, 22q11.2DS is sometimes considered as a genetic model for schizophrenia. Surprisingly, almost no study suggests the use of cognitive and behavioral therapy (CBT) in this indication. We reviewed what should be learned from schizophrenia to develop specific intervention for 22q11.2DS. In our opinion, the first step of CBT approach in 22q11.2DS with psychotic symptoms is to identify precisely which tools can be used among the already available ones. Cognitive behavioral therapy (CBT) targets integrated disorders, i.e. reasoning biases and behavior disorders. In 22q11.2DS, CBT-targeted behavior disorders may take the form of social avoidance and withdrawal or, in the contrary, a more unusual disinhibition and aggressiveness. In our experience, other negative symptoms observed in 22q11.2DS, such as motivation deficit or anhedonia, may also be reduced by CBT. Controlled trials have been studying the benefits of CBT in schizophrenia and several meta-analyses proved its effectiveness. Therefore, it is legitimate to propose this tool in 22q11.2DS, considering symptoms similarities. Overall, CBT is the most effective psychosocial intervention on psychotic symptoms and remains a relevant complement to pharmacological treatments such as antipsychotics.

Group cognitive behaviour therapy combining early intervention with an exclusive focus on single medication-resistant delusional beliefs: a service evaluation

Cognitive behaviour therapy (CBT) is now the psychological treatment of choice for psychosis but meta-analyses indicate a low effect size on delusions, so further innovations are clearly needed, and group CBT for psychosis (GCBTp) is an under-researched area. This study aimed to service-evaluate the feasibility, satisfaction, safety, and effectiveness of a CBT group specifically targeting medication-resistant single delusions in early psychosis patients (EI-GCBTp). Three separate EI-GCBTp groups were run resulting in a total of 11 medication-resistant early psychosis patients. A within-subjects design tested for group change across two time points: pre-baseline (4 weeks before treatment) to baseline (session 1 of treatment) and sessions 1–8 (the treatment period). Thirteen delusion dimensions were measured from three psychosis-specific questionnaires: The Psychotic Symptom Rating Scale (PSYRATS), Characteristics of Delusion Rating Scale, and the Belief Rating Scale. At least three patients attended each group, satisfaction scores were high, and no harm to patients was identified. With reference to effectiveness, the pre-baseline period showed virtually no change. In contrast, across the EI-GCBTp treatment period, the PSYRATS total demonstrated a statistically significant decrease in delusional severity (p < 0.01), a 31% symptom reduction, and a large effect size (Cohen's d = 1.2, 95% confidence interval = −2.53 to 0.05), statistically significant across four delusion dimensions. EI-GCBTp appears feasible, acceptable, safe, and preliminary uncontrolled effectiveness results suggest merit for larger-scale more rigorous testing of this treatment format for possible dimensional improvements of persistent delusions.

The Early Psychosis Intervention Center (EPICENTER): development and six-month outcomes of an American first-episode psychosis clinical service

BACKGROUND

There is growing evidence that specialized clinical services targeted toward individuals early in the course of a psychotic illness may be effective in reducing both the clinical and economic burden associated with these illnesses. Unfortunately, the United States has lagged behind other countries in the delivery of specialized, multi-component care to individuals early in the course of a psychotic illness. A key factor contributing to this lag is the limited available data demonstrating the clinical benefits and cost-effectiveness of early intervention for psychosis among individuals served by the American mental health system. Thus, the goal of this study is to present clinical and cost outcome data with regard to a first-episode psychosis treatment center within the American mental health system: the Early Psychosis Intervention Center (EPICENTER).

METHODS

Sixty-eight consecutively enrolled individuals with first-episode psychosis completed assessments of symptomatology, social functioning, educational/vocational functioning, cognitive functioning, substance use, and service utilization upon enrollment in EPICENTER and after 6 months of EPICENTER care. All participants were provided with access to a multi-component treatment package comprised of cognitive behavioral therapy, family psychoeducation, and metacognitive remediation.

RESULTS

Over the first 6 months of EPICENTER care, participants experienced improvements in symptomatology, social functioning, educational/vocational functioning, cognitive functioning, and substance abuse. The average cost of care during the first 6 months of EPICENTER participation was lower than the average cost during the 6-months prior to joining EPICENTER. These savings occurred despite the additional costs associated with the receipt of EPICENTER care and were driven primarily by reductions in the utilization of inpatient psychiatric services and contacts with the legal system.

CONCLUSIONS

The results of our study suggest that multi-component interventions for first-episode psychosis provided in the US mental health system may be both clinically-beneficial and cost-effective. Although additional research is needed, these findings provide preliminary support for the growing delivery of specialized multi-component interventions for first-episode psychosis within the United States.

First-Episode Services for Psychotic Disorders in the U.S. Public Sector: A Pragmatic Randomized Controlled Trial

OBJECTIVE

This study sought to determine the effectiveness of a comprehensive first-episode service, the clinic for Specialized Treatment Early in Psychosis (STEP), in an urban U.S. community mental health center by comparing it with usual treatment.

METHODS

This pragmatic randomized controlled trial enrolled 120 patients with first-episode psychosis within five years of illness onset and 12 weeks of antipsychotic exposure. Referrals were mostly from inpatient psychiatric units, and enrollees were randomly allocated to STEP or usual treatment. Main outcomes included hospital utilization (primary); the ability to work or attend age-appropriate schooling-or to actively seek these opportunities (vocational engagement); and general functioning. Analysis was by modified intent to treat (excluding only three who withdrew consent) for hospitalization; for other outcomes, only data for completers were analyzed.

RESULTS

After one year, STEP participants had less inpatient utilization compared with those in usual treatment: no psychiatric hospitalizations, 77% versus 56% (risk ratio [RR]=1.38, 95% confidence interval [CI]=1.08-1.58); mean hospitalizations, .33±.70 versus .68±.92 (p=.02); and mean bed-days, 5.34±13.53 versus 11.51±15.04 (p=.05). For every five patients allocated to STEP versus usual treatment, one additional patient avoided hospitalization over the first year (number needed to treat=5; CI=2.7-26.5). STEP participants also demonstrated better vocational engagement (91.7% versus 66.7%; RR=1.40, CI=1.18-1.48) and showed salutary trends in global functioning measures.

CONCLUSIONS

This trial demonstrated the feasibility and effectiveness of a U.S. public-sector model of early intervention for psychotic illnesses. Such services can also support translational research and are a relevant model for other serious mental illnesses.

Group CBT for psychosis in acute care: a review of outcome studies

There is evidence that group cognitive behavioural therapy for psychosis (CBTp) is an effective treatment, but much of this research has been conducted with outpatient populations. The aim of this review was to determine the utility of group CBTp for inpatients. We systematically searched Scopus, Web of Science and EBSCO electronic databases to identify relevant research. We reviewed the resulting articles and included those which had been conducted with inpatients, with symptoms of psychosis, using cognitive behaviour therapy, delivered in a group format. Fourteen articles relating to ten studies were identified. Two were randomized controlled trials; two were cohort studies and the rest were pre-/post-intervention studies. There was considerable heterogeneity between the studies and all had methodological limitations. The findings suggest positive trends towards the reduction of distress associated with psychotic symptoms, increased knowledge of symptoms, decreased affective symptoms and reduced readmissions over several years. However, there is currently not enough evidence to draw any strong conclusions regarding the utility of group CBTp for inpatients due to the small number of studies and limitations in quality and generalizability. Therefore, this review indicates the need for further research, particularly large, methodologically rigorous, randomized controlled trials.

Third-wave strategies for emotion regulation in early psychosis: a pilot study

AIM

Emerging evidence supports the priority of integrating emotion regulation strategies in cognitive behaviour therapy for early psychosis, which is a period of intense distress. Therefore, we developed a new treatment for emotional regulation combining third-wave strategies, namely compassion, acceptance, and mindfulness (CAM) for individuals with early psychosis. The purpose of this study was to examine the acceptability, feasibility and potential clinical utility of CAM.

METHOD

A non-randomized, non-controlled prospective follow-up study was conducted. Outpatients from the First Psychotic Episode Clinic in Montreal were offered CAM, which consisted of 8-week 60-75 min weekly group sessions. Measures of adherence to medication, symptoms, emotional regulation, distress, insight, social functioning and mindfulness were administered at baseline, post-treatment and at 3-month follow up. A short feedback interview was also conducted after the treatment.

RESULTS

Of the 17 individuals who started CAM, 12 (70.6%) completed the therapy. Average class attendance was 77%. Post-treatment feedback indicated that participants found the intervention acceptable and helpful. Quantitative results suggest the intervention was feasible and associated with a large increase in emotional self-regulation, a decrease in psychological symptoms, especially anxiety, depression, and somatic concerns, and improvements in self-care.

CONCLUSION

Overall results support the acceptability, feasibility and potential clinical utility of the new developed treatment. A significant increase in emotional self-regulation and a decrease in affective symptoms were found. No significant changes were observed on measures of mindfulness, insight, distress and social functioning. Controlled research is warranted to validate the effectiveness of the new treatment.

Adapted cognitive-behavioural therapy required for targeting negative symptoms in schizophrenia: meta-analysis and meta-regression

BACKGROUND

There is an increasing interest in cognitive-behavioural therapy (CBT) interventions targeting negative symptoms in schizophrenia. To date, CBT trials primarily focused on positive symptoms and investigated change in negative symptoms only as a secondary outcome. To enhance insight into factors contributing to improvement of negative symptoms, and to identify subgroups of patients that may benefit most from CBT directed at ameliorating negative symptoms, we reviewed all available evidence on these outcomes.

METHOD

A systematic search of the literature was conducted in PsychInfo, PubMed and the Cochrane register to identify randomized controlled trials reporting on the impact of CBT interventions on negative symptoms in schizophrenia. Random-effects meta-analyses were performed on end-of-treatment, short-term and long-term changes in negative symptoms.

RESULTS

A total of 35 publications covering 30 trials in 2312 patients, published between 1993 and 2013, were included. Our results showed studies' pooled effect on symptom alleviation to be small [Hedges' g = 0.093, 95% confidence interval (CI) -0.028 to 0.214, p = 0.130] and heterogeneous (Q = 73.067, degrees of freedom = 29, p < 0.001, τ 2 = 0.081, I 2 = 60.31) in studies with negative symptoms as a secondary outcome. Similar results were found for studies focused on negative symptom reduction (Hedges' g = 0.157, 95% CI -0.10 to 0.409, p = 0.225). Meta-regression revealed that stronger treatment effects were associated with earlier year of publication, lower study quality and with CBT provided individually (as compared with group-based).

CONCLUSIONS

The co-occurring beneficial effect of conventional CBT on negative symptoms found in older studies was not supported by more recent studies. It is now necessary to further disentangle effective treatment ingredients of older studies in order to guide the development of future CBT interventions aimed at negative symptom reduction.

[Cognitive behavior therapy after first-episodes psychosis]

Cognitive behavior therapy (CBT) is recommended for the treatment of first-episode psychosis (FEP) patients. It can be offered in acute state or during the remission of the episode. Up to date, effects of CBT have been examined in several controlled and randomized trials in FEP. Combined with antipsychotic medications, results have demonstrated that CBT decreases positive psychotic symptoms, enhances quality of live, self-esteem and insight, and diminishes the intensity of comorbide symptoms, such as trauma or suicide behavior. CBT might be particularly efficient in individuals wishing to reintegrate premorbide functioning and those with low duration of untreated psychosis. Despite these encouraging results, psychosis orientated CBT are underused in France. The validation of group CBT specifically designed for FEP should enhance the range of patients receiving this treatment. Moreover, early CBT interventions for people at ultra high-risk for psychosis and assertive community treatments should be developed.

Race/ethnicity, education, and treatment parameters as moderators and predictors of outcome in binge eating disorder

OBJECTIVE

Binge eating disorder (BED) is prevalent among individuals from minority racial/ethnic groups and among individuals with lower levels of education, yet the efficacy of psychosocial treatments for these groups has not been examined in adequately powered analyses. This study investigated the relative variance in treatment retention and posttreatment symptom levels accounted for by demographic, clinical, and treatment variables as moderators and predictors of outcome.

METHOD

Data were aggregated from 11 randomized, controlled trials of psychosocial treatments for BED conducted at treatment sites across the United States. Participants were N = 1,073 individuals meeting criteria for BED including n = 946 Caucasian, n = 79 African American, and n = 48 Hispanic/Latino participants. Approximately 86% had some higher education; 85% were female. Multilevel regression analyses examined moderators and predictors of treatment retention, Eating Disorder Examination (EDE) global score, frequency of objective bulimic episodes (OBEs), and OBE remission.

RESULTS

Moderator analyses of race/ethnicity and education were nonsignificant. Predictor analyses revealed African Americans were more likely to drop out of treatment than Caucasians, and lower level of education predicted greater posttreatment OBEs. African Americans showed a small but significantly greater reduction in EDE global score relative to Caucasians. Self-help treatment administered in a group showed negative outcomes relative to other treatment types, and longer treatment was associated with better outcome.

CONCLUSIONS

Observed lower treatment retention among African Americans and lesser treatment effects for individuals with lower levels of educational attainment are serious issues requiring attention. Reduced benefit was observed for shorter treatment length and self-help administered in groups.

Pilot programme of modular symptom-specific group cognitive behaviour therapy in a 'Real World' early intervention in psychosis service

AIM

A modular symptom-specific (MSS) programme of early intervention group cognitive behaviour therapy for psychosis might confer additional therapeutic benefits and clinical and financial efficiency, but the approach is empirically untested. Therefore, we devised a novel MSS programme to test - in a culturally diverse 'Real World' early intervention service - its relevancy, feasibility, acceptability and safety.

METHOD

The MSS programme comprised six different groups across 33 sessions: Psycho-Education (3), Mood-Management (5), Delusions (8), Auditory Hallucinations (8), Past Auditory Hallucinations (3) and Negative Symptoms (6). All patients were eligible for psycho-education, but other groups required a specific symptom.

RESULTS

Patients (n = 166, 37% White) showed wide heterogeneity in the activity, type and number of symptoms, and group-relevant symptoms were common. Eighteen groups have run so far, each type of group at least once, 58/166 (35%) of patients attended across 281/412 (68%) group sessions, 46/58 (79%) of patients re-attended, and the 58 patients attended groups a mean of 4.8 times. Patients were significantly (P < 0.05) more likely to attend the programme if they had a schizophrenia diagnosis, a longer psychotic illness length or one active group-relevant (psychotic/mood) symptom. Diagnostically uncertain psychosis patients were almost significantly (P = 0.05) less likely to attend the programme. duration of untreated psychosis and ethnicity were unrelated to attendance/re-attendance. No group-related risk incidents occurred.

CONCLUSION

A MSS programme approach is highly relevant to early intervention symptom heterogeneity and is feasible, culturally acceptable and safe; it also appears particularly efficient. Future research should now test its clinical efficacy.

Do personality traits matter when choosing a group therapy for early psychosis?

OBJECTIVES

This study aimed at determining the predictive value of personality traits, based on the Five Factor Model (FFM) of personality, on therapeutic outcomes according to specific group treatments for first episode psychosis: cognitive-behavioural therapy (CBT) or skills training for symptom management (SM).

METHODS

Individuals experiencing early psychosis were recruited to participate in a randomized- controlled trial (RCT). Participants were randomized to one of two group treatments or to a wait-list control group. Measures included a personality inventory (NEO-FFI) and outcome measures of symptomatology (BPRS-E) and coping strategies (CCS). Pearson correlation analyses were conducted on 78 individuals and linear regression analyses on 66.

RESULTS

Links were found between personality traits, symptoms, and coping outcome measures, according to specific group treatments. Personality traits were particularly linked to therapeutic changes in active coping strategies, with Conscientiousness accounting for 14% of the variance in the CBT group, Extraversion accounting for 41% of the variance in the SM group, and Openness to experience accounting for 22% of the variance in the control group.

CONCLUSIONS

Individual differences in personality traits for people experiencing early psychosis should be considered when offering psychosocial treatments, since it appears that those with specific traits might benefit more than others in specific group interventions, particularly for interventions that do not solely aim at improving symptoms.

Group CBT for early psychosis--are there still benefits one year later?

Our team recently conducted a randomized controlled trial comparing group cognitive behavior therapy for psychosis (CBTp) to group social skills training for symptom management and a wait-list control group, for early psychosis. The results at post-therapy and six months provided considerable empirical support for the efficacy of the group CBTp. The results of the one-year follow-up are described here. Given the high attrition rates, mostly in the comparison and control conditions, imputations were not possible, so that only the results of those having completed more than 50% of the group CBTp are presented. Significant improvements at 12 months were found for social support and insight. Negative symptoms remained low, whereas positive symptoms went back to pre-therapy levels. Challenges regarding attrition with this clientele are discussed.

Open-ended and Open-door Treatment Groups for Young People with Mental Illness

The concept of open-ended groups is expanded to include an open-door model (OEOD) wherein members with severe mental illnesses, including schizophrenia disorders and bi-polar, can join, leave, and re-enter groups as their life circumstances dictate their availability and willingness for treatment. This model is grounded on the work of Schopler and Galinsky's (1984/2006) and Galinsky and Schopler's (1989) theses on the value and processes of open-ended groups and includes perspectives on mutual aid and group development. Groupwork with the OEOD format is illustrated with examples taken from a group of 79 participants diagnosed with first-episode schizophrenia/schizoaffective disorders, 40 of who had co-occurring substance abuse. Of the 79 participants in the OEOD group program, 70 (89%) remained in treatment for the maximum of 3 years. The over-all value of group treatment for this population is reviewed along with the small number of available publications on open-ended and open-door-type groups.

Patient predictors of symptom and functional outcome following cognitive behaviour therapy or befriending in first-episode psychosis

BACKGROUND

Cognitive behaviour therapy (CBT) is an effective treatment for many, but not all, individuals with psychosis. An important goal is identifying individuals more likely to benefit from CBT to ensure appropriate delivery. The current study aimed to examine patient-related predictors of symptom and functional outcome following CBT and Befriending in first-episode psychosis (FEP).

METHOD

Our original randomized controlled trial compared 14 weeks of CBT (n=31) and Befriending (n=31) in FEP (Jackson et al. 2008). A series of regressions were conducted separately for each group to examine demographic, cognitive, symptoms/illness and functioning variables in predicting positive symptoms (BPRS Psychotic), negative symptoms (SANS Total) and functioning (SOFAS) at 1-year follow-up.

RESULTS

In the CBT group, higher baseline functioning (SOFAS) predicted lower levels of positive symptoms (R(2)=0.19; p=0.023), higher educational achievement and lower levels of avolition symptoms (SANS Avolition) predicted lower levels of total negative symptoms (R(2)=0.38; p=0.003), and working/studying at baseline predicted higher functional outcome (R(2)=0.35; p=0.004) at 1 year. In the Befriending group, premorbid adjustment (PAS Average) was the only variable that predicted 1-year positive symptom (R(2)=0.26; p=0.010), negative symptom (R(2)=0.35; p=0.016) and functional (R(2)=0.48; p=0.002) outcome.

CONCLUSIONS

FEP individuals with higher baseline functioning may benefit more from CBT than those with poorer functioning. Individuals with functional difficulties may benefit from alternative treatments initially, such as supported education or employment.

A review of hearing voices groups: evidence and mechanisms of change

As a heavily stigmatized group, voice hearers often value the chance to meet others with similar experiences. As a result, Hearing Voices Groups (HVGs) are becoming increasingly common in both inpatient and outpatient settings. Where resources are constrained, HVGs are frequently viewed as a desirable alternative to individual therapy and are often preferred by service users themselves. HVGs often vary in their content and structure, with four common approaches: CBT, skills-training, mindfulness and unstructured support groups. This review evaluates the evidence for HVGs and the mechanisms of change for successful interventions. CBT was the only approach with evidence from well-controlled studies. However, several evidence-based treatments share 'key ingredients' which evidence suggests help reduce distress. Successful groups supply a safe context for participants to share experiences, and enable dissemination of strategies for coping with voices as well as considering alternative beliefs about voices. Future research should focus on isolating mechanisms of change and predictors of outcome in order to refine HVG approaches, rather than polarizing them and setting them against one another in efficacy trials.

Integrative circuit models and their implications for the pathophysiologies and treatments of the schizophrenias

A preponderance of evidence indicates that the heterogeneous group of schizophrenias is accompanied by disturbances in neural elements distributed throughout multiple levels of interconnected cortico-striato-pallido-thalamic circuitry. These disturbances include a substantial loss of, or failure to develop, both cells and/or appropriate cellular connections in regions that include at least portions of the hippocampus, parahippocampal gyrus, entorhinal cortex, amygdala, prefrontal and anterior cingulate cortex, superior and transverse temporal gyri, and mediodorsal, anterior, and pulvinar nuclei of the thalamus; they appear to reflect failures of early brain maturation, that become codified into dysfunctional circuit properties, that in the opinion of this author cannot be "undone" or even predictably remediated in any physiological manner by existing pharmacotherapies. These circuit disturbances are variable across individuals with schizophrenia, perhaps reflecting the interaction of multiple different risk genes and multiple different epigenetic events. Evidence for these complex circuit disturbances has significant implications for many areas of schizophrenia research, and for future efforts toward developing more effective therapeutic approaches for this group of disorders. The conclusion of this chapter is that such future efforts should focus on further developing and refining medications that target nodal or convergent circuit points within the limbic-motor interface, with the goal of constraining the scope and severity of psychotic exacerbations, to be used in concert with systematic rehabilitative psychotherapies designed to engage healthy neural systems to compensate for and replace dysfunctional higher circuit elements. This strategy should be applied in both preventative and treatment settings, and disseminated for community delivery via an evidence-based manualized format. In contrast to alternative treatment strategies that range from complex polypharmacy to gene therapies to psychosurgical interventions, the use of combined medication plus targeted cognitive and behavioral psychotherapy has both common sense and time-tested documented efficacy with numerous other neuropsychiatric disorders.

A pilot investigation of the Graduated Recovery Intervention Program (GRIP) for first episode psychosis

The Graduated Recovery Intervention Program (GRIP) is a new individual cognitive-behavioral therapy program designed to facilitate functional recovery in people who have experienced an initial episode of psychosis. The purposes of this study were to evaluate the feasibility and tolerability of the GRIP intervention, and to compare the effectiveness of GRIP versus treatment as usual (TAU) for improving specific clinical and psychosocial outcomes. Forty-six individuals with first episode psychosis were randomized to GRIP+TAU or TAU alone. Primary outcomes focused on social and role functioning, and quality of life. Secondary outcomes included psychotic symptoms, depression, substance use, social support, attitudes toward medications, well-being, and hospitalizations. The results indicate that GRIP was well-tolerated, as evidenced by good attendance and low drop-out rates, and well-received (based on positive feedback from participants). Although the majority of mixed model analyses were not statistically significant, examination of within-group changes and effect sizes suggests an advantage for GRIP over TAU in improving functional outcomes. These advantages and the fact that the GRIP intervention demonstrated feasibility and tolerability suggest that this intervention is worthy of further investigation.
