Burr C, Schnackenberg JK, Weidner F. Talk-based approaches to support people who are distressed by their experience of hearing voices: A scoping review. Front Psychiatry 2022; 13:983999. [PMID: 36299547 PMCID: PMC9589913 DOI: 10.3389/fpsyt.2022.983999] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/01/2022] [Accepted: 09/14/2022] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND The positive effects of both antipsychotic medication and cognitive behavioral therapy in psychosis (CBTp) for people who are distressed by their experience of hearing voices remain limited. As a result, there has been a recent surge in talk-based individual approaches. Many of these continue not to be very well known nor implemented in practice. Some of the approaches may focus more on understanding and dealing constructively with voices, an element that has been identified as potentially helpful by voice hearers. Existing barriers to a wider implementation include both the widespread pathologization of hearing voices and a lack of mental health professionals who have been trained and trusted to carry out these new interventions. METHODS This scoping review aimed to identify and describe a current synthesis of talk-based individual approaches for people who hear voices, including studies independently of method of study or approach, diagnosis of voice hearers nor of the professional background of interventionists. RESULTS Nine different talk-based approaches were identified. These included: (1) Cognitive Behavioral Therapy for Psychosis (CBTp); (2) AVATAR therapy; (3) Making Sense of Voices (MsV) aka Experience Focused Counselling (EFC); (4) Relating Therapy; (5) Acceptance and Commitment Therapy; (6) Smartphone-based Coping-focused Intervention; (7) Prolonged and Virtual Reality Exposure Therapy; (8) Eye Movement Desensitization and Reprocessing, and (9) Individual Mindfulness-based Program for Voice Hearing. The different approaches differed greatly in relation to the number of sessions, length of time offered and the scientific evidence on efficacy. Psychologists represented the main professional group of interventionists. CBTp and the MsV/EFC approach also included health professionals, like nurses, as implementers. Most of the approaches showed positive outcomes in relation to voice related distress levels. None identified overall or voice specific deteriorations. CONCLUSION There appears to be a strong case for the implementation of a broader heterogeneity of approaches in practice. This would also be in line with recommendations for recovery focused services and requirements of voice hearers. A greater emphasis on whole systems implementation and thus the involvement of frontline staff, like nurses, in the delivery of these approaches would likely reduce the research-practice implementation gap.

Svensson B, Hansson L. Perceived curative factors and their relationship to outcome: a study of schizophrenic patients in a comprehensive treatment program based on cognitive therapy. Eur Psychiatry 2020; 13:365-71. [DOI: 10.1016/s0924-9338(99)80704-4] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/11/1998] [Revised: 08/31/1998] [Accepted: 09/16/1998] [Indexed: 10/18/2022] Open
Abstract
SummaryTwenty-eight schizophrenic and other long-term mentally ill patients who were given cognitive therapy sessions twice a week in the context of a comprehensive inpatient treatment program were assessed every 5 weeks regarding perceived curative factors. The assessments were made by a self-rating questionnaire (Curative Factors Questionnaire [CFQ]) and a qualitative assessment from the patients of what they perceived as helpful in treatment. The results showed that milieu therapeutic elements and therapy sessions were perceived as the most helpful throughout the treatment period. No correlations were found between patient characteristics and perceived curative factors. The factors “instillation of hope”, “problem solution” and “learning I’m not alone” as rated in the initial phase of treatment showed a positive relationship with a favourable outcome of treatment at discharge.

Abstract
BackgroundTo date, cognitive–behavioural therapy (CBT) trials have primarily focused on clinical recovery; however, personal recovery is actually the fundamental aspect of the recovery process. The aim of this study was to summarise and synthesise the existing evidence regarding the effectiveness of CBT for personal recovery in patients with schizophrenia.AimThis study aimed to determine the effectiveness of CBT for personal recovery in patients with schizophrenia.MethodsA systematic search of the literature in PsycINFO, PubMed, Cochrane (CENTRAL), Embase and Web of Science (SCI) was conducted to identify randomised controlled trials reporting the impact of CBT interventions on personal recovery in patients with schizophrenia. The estimated effect sizes of the main study outcomes were calculated to estimate the magnitude of the treatment effects of CBT on personal recovery. We also evaluated the CBT’s effect size at the end-of-treatment and long-term (follow-up) changes in some aspects of personal recovery.ResultsTwenty-five studies were included in the analysis. The effect of CBT on personal recovery was 2.27 (95% CI 0.10 to 4.45; I2=0%; p=0.04) at post-treatment and the long-term effect size was 2.62 (95% CI 0.51 to 4.47; I2=0%; p=0.02). During the post-treatment period, the pooled effect size of CBT was 0.01 (95% CI −0.12 to 0.15; I2=33.0%; p>0.05) for quality of life (QoL), 0.643 (95% CI 0.056 to 1.130; I2=30.8%; p<0.01) for psychological health-related QoL, −1.77 (95% CI −3.29 to −0.25; I2=40%; p=0.02) for hopelessness and 1.85 (95% CI 0.69 to 3.01; I2=41%; p<0.01) for self-esteem. We also summarised the effects of CBT on QoL (subscale scores not included in the evaluation of the pooled effect size), self-confidence and connectedness, and all results corresponded to positive effects. However, there was insufficient evidence regarding the long-term effects of CBT on personal recovery.ConclusionsCBT is an effective therapy with meaningful clinical effect sizes on personal recovery and some aspects of personal recovery of schizophrenia after treatment. However, the effect is relatively immediate and rapidly decreases as time progresses. Therefore, in the future, more studies should focus on the mechanism of CBT for personal recovery and the factors that influence the long-term effects of CBT.Trial registration numberCRD42018085643.

Lincoln TM, Peters E. A systematic review and discussion of symptom specific cognitive behavioural approaches to delusions and hallucinations. Schizophr Res 2019; 203:66-79. [PMID: 29352708 DOI: 10.1016/j.schres.2017.12.014] [Citation(s) in RCA: 55] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/06/2017] [Revised: 12/21/2017] [Accepted: 12/26/2017] [Indexed: 12/29/2022]
Abstract
Studies on cognitive behavioural therapy for psychosis (CBTp) have developed from evaluating generic approaches to focusing on specific symptoms. The evidence for targeted studies on delusions and hallucinations was reviewed. We included randomized controlled trials (RCTs) examining the effect of individualized CBT-based interventions focusing either on delusions or on hallucinations. Twelve suitable RCTs were identified. Four RCTs focused on delusions, of which three took a focused approach targeting mechanisms assumed causal to persecutory delusions. Eight RCTs focused on hallucinations, a common component of these studies being a focus on the perceived power imbalance between the voice(s) and the voice-hearer, to reduce distress and dysfunction. Only three RCTS were powered adequately; the remainder were pilot trials. All trials reported effect sizes against treatment-as-usual above d=0.4 on at least one primary outcome at post-therapy, with several effects in the large range. Effects on the primary outcome were maintained for five of the seven studies that had significant outcomes and reported a follow-up comparison, but most of the follow-up periods were brief. Although targeted studies are still in their infancy, the results are promising with a tendency towards higher effects compared to the small-to-moderate range found for generic CBTp. In clinical practice, CBTp will need to continue including a range of approaches that can be adapted to patients in a flexible manner according to the primary goals and prevalent combination of symptoms. However, symptom-focused and causal-interventionist approaches are informative research strategies to evaluate the efficacy of separate components or mechanisms of generic CBTp.

Abstract
Background: Roughly 30% of schizophrenia patients fail to respond to at least two antipsychotic trials. Psychosis has been traditionally considered to be poorly sensitive to psychotherapy. Nevertheless, there is increasing evidence that psychological interventions could be considered in treatment-resistant psychosis (TRP). Despite the relevance of the issue and the emerging neurobiological underpinnings, no systematic reviews have been published. Here, we show a systematic review of psychotherapy interventions in TRP patients of the last 25 years. Methods: The MEDLINE/PubMed, ISI WEB of Knowledge, and Scopus databases were inquired from January 1, 1993, to August 1, 2018, for reports documenting augmentation or substitution with psychotherapy for treatment-resistant schizophrenia (TRS) and TRP patients. Quantitative data fetched by Randomized Controlled Trials (RCTs) were pooled for explorative meta-analysis. Results: Forty-two articles have been found. Cognitive behavioral therapy (CBT) was the most frequently recommended psychotherapy intervention for TRS (studies, n = 32, 76.2%), showing efficacy for general psychopathology and positive symptoms as documented by most of the studies, but with uncertain efficacy on negative symptoms. Other interventions showed similar results. The usefulness of group therapy was supported by the obtained evidence. Few studies focused on negative symptoms. Promising results were also reported for resistant early psychosis. Limitations: Measurement and publication bias due to the intrinsic limitations of the appraised original studies. Conclusions: CBT, psychosocial intervention, supportive counseling, psychodynamic psychotherapy, and other psychological interventions can be recommended for clinical practice. More studies are needed, especially for non-CBT interventions and for all psychotherapies on negative symptoms.

Abstract
BACKGROUND Cognitive behavioural therapy (CBT) is a psychosocial treatment that aims to re-mediate distressing emotional experiences or dysfunctional behaviour by changing the way in which a person interprets and evaluates the experience or cognates on its consequence and meaning. This approach helps to link the person's feelings and patterns of thinking which underpin distress. CBT is now recommended by the National Institute for Health and Care Excellence (NICE) as an add-on treatment for people with a diagnosis of schizophrenia. This review is also part of a family of Cochrane CBT reviews for people with schizophrenia. OBJECTIVES To assess the effects of cognitive behavioural therapy added to standard care compared with standard care alone for people with schizophrenia. SEARCH METHODS We searched the Cochrane Schizophrenia Group's Trials Register (up to March 6, 2017). This register is compiled by systematic searches of major resources (including AMED, BIOSIS CINAHL, Embase, MEDLINE, PsycINFO, PubMed, and registries of clinical trials) and their monthly updates, handsearches, grey literature, and conference proceedings, with no language, date, document type, or publication status limitations for inclusion of records into the register. SELECTION CRITERIA We selected all randomised controlled clinical trials (RCTs) involving people diagnosed with schizophrenia or related disorders, which compared adding CBT to standard care with standard care given alone. Outcomes of interest included relapse, rehospitalisation, mental state, adverse events, social functioning, quality of life, and satisfaction with treatment.We included studies fulfilling the predefined inclusion criteria and reporting useable data. DATA COLLECTION AND ANALYSIS We complied with the Cochrane recommended standard of conduct for data screening and collection. Where possible, we calculated relative risk (RR) and its 95% confidence interval (CI) for binary data and mean difference (MD) and its 95% confidence interval for continuous data. We assessed risk of bias for included studies and created a 'Summary of findings' table using GRADE. MAIN RESULTS This review now includes 60 trials with 5,992 participants, all comparing CBT added to standard care with standard care alone. Results for the main outcomes of interest (all long term) showed no clear difference between CBT and standard care for relapse (RR 0.78, 95% CI 0.61 to 1.00; participants = 1538; studies = 13, low-quality evidence). Two trials reported global state improvement. More participants in the CBT groups showed clinically important improvement in global state (RR 0.57, 95% CI 0.39 to 0.84; participants = 82; studies = 2 , very low-quality evidence). Five trials reported mental state improvement. No differences in mental state improvement were observed (RR 0.81, 95% CI 0.65 to 1.02; participants = 501; studies = 5, very low-quality evidence). In terms of safety, adding CBT to standard care may reduce the risk of having an adverse event (RR 0.44, 95% CI 0.27 to 0.72; participants = 146; studies = 2, very low-quality evidence) but appears to have no effect on long-term social functioning (MD 0.56, 95% CI -2.64 to 3.76; participants = 295; studies = 2, very low-quality evidence, nor on long-term quality of life (MD -3.60, 95% CI -11.32 to 4.12; participants = 71; study = 1, very low-quality evidence). It also has no effect on long-term satisfaction with treatment (measured as 'leaving the study early') (RR 0.93, 95% CI 0.77 to 1.12; participants = 1945; studies = 19, moderate-quality evidence). AUTHORS' CONCLUSIONS Relative to standard care alone, adding CBT to standard care appears to have no effect on long-term risk of relapse. A very small proportion of the available evidence indicated CBT plus standard care may improve long term global state and may reduce the risk of adverse events. Whether adding CBT to standard care leads to clinically important improvement in patients' long-term mental state, quality of life, and social function remains unclear. Satisfaction with care (measured as number of people leaving the study early) was no higher for participants receiving CBT compared to participants receiving standard care. It should be noted that although much research has been carried out in this area, the quality of evidence available is poor - mostly low or very low quality and we still cannot make firm conclusions until more high quality data are available.

Abstract
BACKGROUND Cognitive behavioural therapy (CBT) is a psychosocial treatment that aims to help individuals re-evaluate their appraisals of their experiences that can affect their level of distress and problematic behaviour. CBT is now recommended by the National Institute for Health and Care Excellence (NICE) as an add-on treatment for people with a diagnosis of schizophrenia. Other psychosocial therapies that are often less expensive are also available as an add-on treatment for people with schizophrenia. This review is also part of a family of Cochrane Reviews on CBT for people with schizophrenia. OBJECTIVES To assess the effects of CBT compared with other psychosocial therapies as add-on treatments for people with schizophrenia. SEARCH METHODS We searched the Cochrane Schizophrenia Group's Study Based Register of Trials (latest 6 March, 2017). This register is compiled by systematic searches of major resources (including AMED, BIOSIS CINAHL, Embase, MEDLINE, PsycINFO, PubMed, and registries of clinical trials) and their monthly updates, handsearches, grey literature, and conference proceedings, with no language, date, document type, or publication status limitations for inclusion of records into the register. SELECTION CRITERIA We selected randomised controlled trials (RCTs) involving people with schizophrenia who were randomly allocated to receive, in addition to their standard care, either CBT or any other psychosocial therapy. Outcomes of interest included relapse, global state, mental state, adverse events, social functioning, quality of life and satisfaction with treatment. We included trials meeting our inclusion criteria and reporting useable data. DATA COLLECTION AND ANALYSIS We reliably screened references and selected trials. Review authors, working independently, assessed trials for methodological quality and extracted data from included studies. We analysed dichotomous data on an intention-to-treat basis and continuous data with 60% completion rate. Where possible, for binary data we calculated risk ratio (RR), for continuous data we calculated mean difference (MD), all with 95% confidence intervals (CIs). We used a fixed-effect model for analyses unless there was unexplained high heterogeneity. We assessed risk of bias for the included studies and used the GRADE approach to produce a 'Summary of findings' table for our main outcomes of interest. MAIN RESULTS The review now includes 36 trials with 3542 participants, comparing CBT with a range of other psychosocial therapies that we classified as either active (A) (n = 14) or non active (NA) (n = 14). Trials were often small and at high or unclear risk of bias. When CBT was compared with other psychosocial therapies, no difference in long-term relapse was observed (RR 1.05, 95% CI 0.85 to 1.29; participants = 375; studies = 5, low-quality evidence). Clinically important change in global state data were not available but data for rehospitalisation were reported. Results showed no clear difference in long term rehospitalisation (RR 0.96, 95% CI 0.82 to 1.14; participants = 943; studies = 8, low-quality evidence) nor in long term mental state (RR 0.82, 95% CI 0.67 to 1.01; participants = 249; studies = 4, low-quality evidence). No long-term differences were observed for death (RR 1.57, 95% CI 0.62 to 3.98; participants = 627; studies = 6, low-quality evidence). Only average endpoint scale scores were available for social functioning and quality of life. Social functioning scores were similar between groups (long term Social Functioning Scale (SFS): MD 8.80, 95% CI -4.07 to 21.67; participants = 65; studies = 1, very low-quality evidence), and quality of life scores were also similar (medium term Modular System for Quality of Life (MSQOL): MD -4.50, 95% CI -15.66 to 6.66; participants = 64; studies = 1, very low-quality evidence). There was a modest but clear difference favouring CBT for satisfaction with treatment - measured as leaving the study early (RR 0.86, 95% CI 0.75 to 0.99; participants = 2392; studies = 26, low quality evidence). AUTHORS' CONCLUSIONS Evidence based on data from randomised controlled trials indicates there is no clear and convincing advantage for cognitive behavioural therapy over other - and sometimes much less sophisticated and expensive - psychosocial therapies for people with schizophrenia. It should be noted that although much research has been carried out in this area, the quality of evidence available is mostly low or of very low quality. Good quality research is needed before firm conclusions can be made.

Abstract
BackgroundAfrican-Caribbean people in the UK experience the highest incidence of schizophrenia and the greatest inequity in mental health care. There is an urgent need to improve their access to evidence-based care and outcomes. Family intervention (FI) is a National Institute for Health and Care Excellence-approved psychosocial intervention. Although clinically effective and cost-effective for schizophrenia, it is rarely offered. Evidence for any research into FI is lacking for ethnic minority people generally and for African-Caribbean people specifically.Aims(1) To assess the feasibility of delivering a novel, culturally appropriate psychosocial intervention within a ‘high-risk’ population to improve engagement and access to evidence-based care. (2) To test the feasibility and acceptability of delivering FI via ‘proxy families’.DesignA mixed-methods, feasibility cohort study, incorporating focus groups and an expert consensus conference.SettingTwo mental health trusts in north-west England.ParticipantsWe recruited a convenience sample of 31 African-Caribbean service users. Twenty-six family units [service users, relatives/family support members (FSMs) or both] commenced therapy. Half of the service users (n = 13, 50%), who did not have access to their biological families, participated by working with FSMs.InterventionsAn extant FI model was culturally adapted with key stakeholders using a literature-derived framework [Culturally adapted Family Intervention (CaFI)]. Ten CaFI sessions were offered to each service user and associated family.Main outcome measuresRecruitment (number approached vs. number consented), attendance (number of sessions attended), attrition (number of dropouts at each time point), retention (proportion of participants who completed therapy sessions), and completeness of outcome measurement.ResultsOf 74 eligible service users, 31 (42%) consented to take part in the feasibility trial. The majority (n = 21, 67.7%) were recruited from community settings, seven (22.6%) were recruited from rehabilitation settings and three (9.7%) were recruited from acute wards. Twenty-four family units (92%) completed all 10 therapy sessions. The proportion who completed treatment was 77.42% (24/31). The mean number of sessions attended was 7.90 (standard deviation 3.96 sessions) out of 10. It proved feasible to collect a range of outcome data at baseline, post intervention and at the 3-month follow-up. The rating of sessions and the qualitative findings indicated that CaFI was acceptable to service users, families, FSMs and health-care professionals.LimitationsThe lack of a control group and the limited sample size mean that there is insufficient power to assess efficacy. The findings are not generalisable beyond this population.ConclusionsIt proved feasible to culturally adapt and test FI with a sample of African-Caribbean service users and their families. Our study yielded high rates of recruitment, attendance, retention and data completion. We delivered CaFI via FSMs in the absence of biological families. This novel aspect of the study has implications for other groups who do not have access to their biological families. We also demonstrated the feasibility of collecting a range of outcomes to inform future trials and confirmed CaFI’s acceptability to key stakeholders. These are important findings. If CaFI can be delivered to the group of service users with the most serious and persistent disparities in schizophrenia care, it has the potential to be modified for and delivered to other underserved groups.Future workA fully powered, multicentre trial, comparing CaFI with usual care, is planned.Trial registrationCurrent Controlled Trials ISRCTN94393315.FundingThis project was funded by the National Institute for Health Research (NIHR) Health Services and Delivery Research programme and will be published in full inHealth Services and Delivery Research; Vol. 6, No. 32.

Abstract
Background The effect of cognitive behavioural therapy for psychosis (CBTp) on the core symptoms of schizophrenia has proven contentious, with current meta-analyses finding at most only small effects. However, it has been suggested that the effects of CBTp in areas other than psychotic symptoms are at least as important and potentially benefit from the intervention. Method We meta-analysed RCTs investigating the effectiveness of CBTp for functioning, distress and quality of life in individuals diagnosed with schizophrenia and related disorders. Data from 36 randomised controlled trials (RCTs) met our inclusion criteria- 27 assessing functioning (1579 participants); 8 for distress (465 participants); and 10 for quality of life (592 participants). Results The pooled effect size for functioning was small but significant for the end-of-trial (0.25: 95% CI: 0.14 to 0.33); however, this became non-significant at follow-up (0.10 [95%CI -0.07 to 0.26]). Although a small benefit of CBT was evident for reducing distress (0.37: 95%CI 0.05 to 0.69), this became nonsignificant when adjusted for possible publication bias (0.18: 95%CI -0.12 to 0.48). Finally, CBTp showed no benefit for improving quality of life (0.04: 95% CI: -0.12 to 0.19). Conclusions CBTp has a small therapeutic effect on functioning at end-of-trial, although this benefit is not evident at follow-up. Although CBTp produced a small benefit on distress, this was subject to possible publication bias and became nonsignificant when adjusted. We found no evidence that CBTp increases quality of life post-intervention.

Abstract
This paper presents the coping strategies developed by one patient with 18 years experience of managing her own schizophrenic illness. The interventions which evolved gave her significant control over her illness. We report her experiences and emphasise that for some patients with treatment resistant schizophrenia, the patients themselves may have expertise in managing their symptoms.

Abstract
Relapse in schizophrenia remains common and cannot be entirely eliminated even by the best combination of biological and psychosocial interventions (Linszen et al, 1998). Relapse prevention is crucial as each relapse may result in the growth of residual symptoms (Shepherd et al, 1989) and accelerating social disablement (Hogarty et al, 1991). Many patients feel ‘entrapped’ by their illnesses, a factor highly correlated with depression (Birchwood et al, 1993), and have expressed a strong interest in learning to recognise and prevent impending psychotic relapse.

Abstract
The first line of treatment for patients with psychotic disorders such as schizophrenia is neuroleptic medication. Neuroleptics have provided substantial benefits to patients with this type of severe mental illness since their discovery as a treatment for psychosis in the 1950s. Despite this, there are still a large number of patients who do not respond fully to neuroleptic medication or who are not able to tolerate it. For example, although as many as 70% of patients are substantially improved following drug treatment, a considerable proportion continue to experience persistent, distressing and recurrent symptoms. In a survey of patients in a London psychiatric hospital, Curson et al (1988) found that just under half of the patients continued to experience hallucinations and delusions despite the prescription of medication. In addition, many patients experience intolerable side-effects or do not wish to comply with neuroleptic medication, yet look for some effective alternative. Depression, anxiety and a high rate of suicide are additional problems faced by patients with schizophrenia.

Abstract
Psychotic symptoms in elderly people can be seen in a variety of conditions. This article reviews treatment strategies (both pharmacological and non-pharmacological) for such symptoms in schizophrenia and neurodegenerative disorders in this population. Traditionally, antipsychotics have been the most commonly used treatment for psychotic symptoms. Their usefulness in treating schizophrenia, both chronic and late onset, is well established and the atypical antipsychotics, which have a better side-effect profile, are more suitable for elderly people. More recently, there have been increasing concerns about their safety in psychoses due to dementia. The debate about whether an absolute ban on their use is required is still ongoing, but it has highlighted the need for adopting and developing non-pharmacological interventions.

Abstract
The term ‘challenging behaviour’ was introduced in North America in the 1980s, and was originally used to describe problematic behaviours in people with ‘mental retardation’ (learning disabilities). Challenging behaviour can, however, occur across the intellectual spectrum, being particularly prevalent in populations with psychiatric disorder.

Abstract
SummarySystemic lupus erythematosus (SLE) is a disorder which can affect the central nervous system and result in a broad range of psychiatric syndromes such as psychosis, mood disorders, acute confusion and cognitive dysfunction. Despite the robust nomenclature of neuropsychiatric SLE (NPSLE), psychiatric syndromes in patients are often non-specific and may be secondary to concurrent non-SLE-related conditions and complications of medical therapies. Although the exact immunopathological mechanism for psychiatric presentation remains elusive, prompt exclusion of other factors contributing to the psychiatric symptoms coupled with effective assessment strategies and management with immunosuppression and psychiatric therapy are imperative. Psychiatrists and rheumatologists must work in close liaison to identify, treat and prognosticate patients with psychiatric syndromes in order to improve their quality of life, vocational aptitude and, ultimately, survival.

Abstract
Psychiatrists who work with patients with severe mental illness often are more focused on diagnosis, medical management, and psychopharmacology than on psychosocial treatments. Furthermore, many psychosocial interventions that show great promise may not be available locally, making it harder for psychiatrists to recognize emerging trends. Finally, there has not been an update in the American Psychiatric Association's Practice Guideline for the Treatment of Schizophrenia for many years, and the most recent Patient Outcomes Research Team (PORT) review of evidence-based psychosocial treatments for schizophrenia was published eight years ago. This article reviews a selection of psychosocial interventions that have shown success in treating some of the more vexing and persistent core schizophrenia symptoms that often continue despite optimal pharmacologic treatment; formerly these had been considered too risky or out of reach for psychosocial intervention. The interventions reviewed include cognitive-behavioral therapy for psychosis (CBTp), which aims to reduce distress and disability from psychotic symptoms; CBT and other behavioral interventions focused for comorbid posttraumatic stress syndrome; cognitive training (remediation) interventions that use computerized training programs to reduce the severity and consequence of cognitive impairment associated with schizophrenia; clubhouse and peer support models that address the social alienation and social defeat endemic to persons with severe mental illness; and supported employment interventions that are effective in helping patients get back to work in a competitive job environment. The interventions are reviewed with the needs of the prescribing mental health clinician in mind. Each intervention's strengths and weaknesses are described, as well as their role in recovery-oriented treatment services.

Investigating the efficacy of an individualized metacognitive therapy program (MCT+) for psychosis: study protocol of a multi-center randomized controlled trial. BMC Psychiatry 2016; 16:51. [PMID: 26921116 PMCID: PMC4769526 DOI: 10.1186/s12888-016-0756-2] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/10/2016] [Accepted: 02/18/2016] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Psychological interventions are increasingly recommended as adjunctive treatments for psychosis, but their implementation in clinical practice is still insufficient. The individualized metacognitive therapy program (MCT+; www.uke.de/mct_plus ) represents a low-threshold psychotherapeutic approach that synthesizes group metacognitive training (MCT) and cognitive behavioral therapy for psychosis, and addresses specific cognitive biases that are involved in the onset and maintenance of psychosis. It aims to "plant the seed of doubt" regarding rigid delusional convictions and to encourage patients to critically reflect, extend and change their approach to problem solving. Its second edition also puts more emphasis on affective symptoms. A recent meta-analysis of metacognitive interventions (MCT, MCT+) indicate small to moderate effects on positive symptoms and delusions, as well as high rates of acceptance. Nonetheless, no long-term studies of MCT+ involving large samples have been conducted. METHODS The goal of the present multi-center, observer-blind, parallel-group, randomized controlled trial is to compare the efficacy of MCT+ against an active control (cognitive remediation; MyBrainTraining(©)) in 328 patients with psychosis at three time points (baseline, immediately after intervention [6 weeks] and 6 months later). The primary outcome is change in psychosis symptoms over the 6-month follow-up period as assessed by the delusion subscale of the Psychotic Symptom Rating Scale. Secondary outcomes include jumping to conclusions, other positive symptoms of schizophrenia, depressive symptoms, self-esteem, quality of life, and cognitive insight. The study also seeks to elucidate mediating factors that promote versus impede symptom improvement across time. DISCUSSION This is the first multi-center randomized controlled trial to test the efficacy of individualized MCT+ in a large sample of patients with psychosis. The rationale for the trial, the design, and the strengths and limitations of the study are discussed. TRIAL REGISTRATION The trial is registered through the German Clinical Trials Register ( www.drks.de ) as DRKS00008001 . Registered 6 May 2015.

Abstract
BACKGROUND Supportive therapy is often used in everyday clinical care and in evaluative studies of other treatments. OBJECTIVES To review the effects of supportive therapy compared with standard care, or other treatments in addition to standard care for people with schizophrenia. SEARCH METHODS For this update, we searched the Cochrane Schizophrenia Group's register of trials (November 2012). SELECTION CRITERIA All randomised trials involving people with schizophrenia and comparing supportive therapy with any other treatment or standard care. DATA COLLECTION AND ANALYSIS We reliably selected studies, quality rated these and extracted data. For dichotomous data, we estimated the risk ratio (RR) using a fixed-effect model with 95% confidence intervals (CIs). Where possible, we undertook intention-to-treat analyses. For continuous data, we estimated the mean difference (MD) fixed-effect with 95% CIs. We estimated heterogeneity (I(2) technique) and publication bias. We used GRADE to rate quality of evidence. MAIN RESULTS Four new trials were added after the 2012 search. The review now includes 24 relevant studies, with 2126 participants. Overall, the evidence was very low quality.We found no significant differences in the primary outcomes of relapse, hospitalisation and general functioning between supportive therapy and standard care.There were, however, significant differences favouring other psychological or psychosocial treatments over supportive therapy. These included hospitalisation rates (4 RCTs, n = 306, RR 1.82 CI 1.11 to 2.99, very low quality of evidence), clinical improvement in mental state (3 RCTs, n = 194, RR 1.27 CI 1.04 to 1.54, very low quality of evidence) and satisfaction of treatment for the recipient of care (1 RCT, n = 45, RR 3.19 CI 1.01 to 10.7, very low quality of evidence). For this comparison, we found no evidence of significant differences for rate of relapse, leaving the study early and quality of life.When we compared supportive therapy to cognitive behavioural therapy CBT), we again found no significant differences in primary outcomes. There were very limited data to compare supportive therapy with family therapy and psychoeducation, and no studies provided data regarding clinically important change in general functioning, one of our primary outcomes of interest. AUTHORS' CONCLUSIONS There are insufficient data to identify a difference in outcome between supportive therapy and standard care. There are several outcomes, including hospitalisation and general mental state, indicating advantages for other psychological therapies over supportive therapy but these findings are based on a few small studies where we graded the evidence as very low quality. Future research would benefit from larger trials that use supportive therapy as the main treatment arm rather than the comparator.

Abstract
OBJECTIVE "Michael's game" (MG) is a card game targeting the ability to generate alternative hypotheses to explain a given experience. The main objective was to evaluate the effect of MG on delusional conviction as measured by the primary study outcome: the change in scores on the conviction subscale of the Peters delusions inventory (PDI-21). Other variables of interest were the change in scores on the distress and preoccupation subscales of the PDI-21, the brief psychiatric rating scale, the Beck cognitive insight scale, and belief flexibility assessed with the Maudsley assessment of delusions schedule (MADS). METHODS We performed a parallel, assessor-blinded, randomized controlled superiority trial comparing treatment as usual plus participation in MG with treatment as usual plus being on a waiting list (TAU) in a sample of adult outpatients with psychotic disorders and persistent positive psychotic symptoms at inclusion. RESULTS The 172 participants were randomized, with 86 included in each study arm. Assessments were performed at inclusion (T1: baseline), at 3 months (T2: post-treatment), and at 6 months after the second assessment (T3: follow-up). At T2, a positive treatment effect was observed on the primary outcome, the PDI-21 conviction subscale (p = 0.005). At T3, a sustained effect was observed for the conviction subscale (p = 0.002). Further effects were also observed at T3 on the PDI-21 distress (p = 0.002) and preoccupation subscales (p = 0.001), as well as on one of the MADS measures of belief flexibility ("anything against the belief") (p = 0.001). CONCLUSION The study demonstrated some significant beneficial effect of MG.

Abstract
OBJECTIVE Metacognitive training is an eight-module, group-based treatment programme for people with schizophrenia that targets the cognitive biases (i.e. problematic thinking styles) thought to contribute to the genesis and maintenance of delusions. The present article is an investigation into the efficacy of a shorter, more targeted, single-module metacognitive training programme, administered individually, which focuses specifically on improving cognitive biases that are thought to be driven by a 'hypersalience of evidence-hypothesis matches' mechanism (e.g. jumping to conclusions, belief inflexibility, reasoning heuristics, illusions of control). It was hypothesised that a more targeted metacognitive training module could still improve performance on these bias tasks and reduce delusional ideation, while improving insight and quality of life. METHOD A sample of 28 patients diagnosed with schizophrenia and mild delusions either participated in the hour-long, single-session, targeted metacognitive training programme (n = 14), or continued treatment as usual (n = 14). All patients were assessed using clinical measures gauging overall positive symptomology, delusional ideation, quality of life and insight, and completed two cognitive bias tasks designed to elucidate the representativeness and illusion of control biases. RESULTS After a 2-week, post-treatment interval, targeted metacognitive training patients exhibited significant decreases in delusional severity and conviction, significantly improved clinical insight, and significant improvements on the cognitive bias tasks, relative to the treatment-as-usual controls. Performance improvements on the cognitive bias tasks significantly correlated with the observed reductions in overall positive symptomology. Patients also evaluated the training positively. CONCLUSIONS Although interpretations of these results are limited due to the lack of an optimally designed, randomised controlled trial and a small sample size, the results are promising and warrant further investigation into targeted versions of the metacognitive training programme.

Abstract
Early case studies and noncontrolled trial studies focusing on the treatment of delusions and hallucinations have laid the foundation for more recent developments in comprehensive cognitive behavioral therapy (CBT) interventions for schizophrenia. Seven randomized, controlled trial studies testing the efficacy of CBT for schizophrenia were identified by electronic search (MEDLINE and PsychInfo) and by personal correspondence. After a review of these studies, effect size (ES) estimates were computed to determine the statistical magnitude of clinical change in CBT and control treatment conditions. CBT has been shown to produce large clinical effects on measures of positive and negative symptoms of schizophrenia. Patients receiving routine care and adjunctive CBT have experienced additional benefits above and beyond the gains achieved with routine care and adjunctive supportive therapy. These results reveal promise for the role of CBT in the treatment of schizophrenia although additional research is required to test its efficacy, long-term durability, and impact on relapse rates and quality of life. Clinical refinements are needed also to help those who show only minimal benefit with the intervention.

Abstract
BACKGROUND Cognitive behavioural therapy (CBT) is now a recommended treatment for people with schizophrenia. This approach helps to link the person's distress and problem behaviours to underlying patterns of thinking. OBJECTIVES To review the effects of CBT for people with schizophrenia when compared with other psychological therapies. SEARCH METHODS We searched the Cochrane Schizophrenia Group Trials Register (March 2010) which is based on regular searches of CINAHL, EMBASE, MEDLINE and PsycINFO. We inspected all references of the selected articles for further relevant trials, and, where appropriate, contacted authors. SELECTION CRITERIA All relevant randomised controlled trials (RCTs) of CBT for people with schizophrenia-like illnesses. DATA COLLECTION AND ANALYSIS Studies were reliably selected and assessed for methodological quality. Two review authors, working independently, extracted data. We analysed dichotomous data on an intention-to-treat basis and continuous data with 65% completion rate are presented. Where possible, for dichotomous outcomes, we estimated a risk ratio (RR) with the 95% confidence interval (CI) along with the number needed to treat/harm. MAIN RESULTS Thirty papers described 20 trials. Trials were often small and of limited quality. When CBT was compared with other psychosocial therapies, no difference was found for outcomes relevant to adverse effect/events (2 RCTs, n = 202, RR death 0.57 CI 0.12 to 2.60). Relapse was not reduced over any time period (5 RCTs, n = 183, RR long-term 0.91 CI 0.63 to 1.32) nor was rehospitalisation (5 RCTs, n = 294, RR in longer term 0.86 CI 0.62 to 1.21). Various global mental state measures failed to show difference (4 RCTs, n = 244, RR no important change in mental state 0.84 CI 0.64 to 1.09). More specific measures of mental state failed to show differential effects on positive or negative symptoms of schizophrenia but there may be some longer term effect for affective symptoms (2 RCTs, n = 105, mean difference (MD) Beck Depression Inventory (BDI) -6.21 CI -10.81 to -1.61). Few trials report on social functioning or quality of life. Findings do not convincingly favour either of the interventions (2 RCTs, n = 103, MD Social Functioning Scale (SFS) 1.32 CI -4.90 to 7.54; n = 37, MD EuroQOL -1.86 CI -19.20 to 15.48). For the outcome of leaving the study early, we found no significant advantage when CBT was compared with either non-active control therapies (4 RCTs, n = 433, RR 0.88 CI 0.63 to 1.23) or active therapies (6 RCTs, n = 339, RR 0.75 CI 0.40 to 1.43) AUTHORS' CONCLUSIONS Trial-based evidence suggests no clear and convincing advantage for cognitive behavioural therapy over other - and sometime much less sophisticated - therapies for people with schizophrenia.

Abstract
BACKGROUND Most people with schizophrenia have a cyclical pattern of illness characterised by remission and relapses. The illness can reduce the ability of self-care and functioning and can lead to the illness becoming disabling. Life skills programmes, emphasising the needs associated with independent functioning, are often a part of the rehabilitation process. These programmes have been developed to enhance independent living and quality of life for people with schizophrenia. OBJECTIVES To review the effects of life skills programmes compared with standard care or other comparable therapies for people with chronic mental health problems. SEARCH METHODS We searched the Cochrane Schizophrenia Group Trials Register (June 2010). We supplemented this process with handsearching and scrutiny of references. We inspected references of all included studies for further trials. SELECTION CRITERIA We included all relevant randomised or quasi-randomised controlled trials for life skills programmes versus other comparable therapies or standard care involving people with serious mental illnesses. DATA COLLECTION AND ANALYSIS We extracted data independently. For dichotomous data we calculated relative risks (RR) and their 95% confidence intervals (CI) on an intention-to-treat basis, based on a random-effects model. For continuous data, we calculated mean differences (MD), again based on a random-effects model. MAIN RESULTS We included seven randomised controlled trials with a total of 483 participants. These evaluated life skills programmes versus standard care, or support group. We found no significant difference in life skills performance between people given life skills training and standard care (1 RCT, n = 32, MD -1.10; 95% CI -7.82 to 5.62). Life skills training did not improve or worsen study retention (5 RCTs, n = 345, RR 1.16; 95% CI 0.40 to 3.36). We found no significant difference in PANSS positive, negative or total scores between life skills intervention and standard care. We found quality of life scores to be equivocal between participants given life skills training (1 RCT, n = 32, MD -0.02; 95% CI -0.07 to 0.03) and standard care. Life skills compared with support groups also did not reveal any significant differences in PANSS scores, quality of life, or social performance skills (1 RCT, n = 158, MD -0.90; 95% CI -3.39 to 1.59). AUTHORS' CONCLUSIONS Currently there is no good evidence to suggest life skills programmes are effective for people with chronic mental illnesses. More robust data are needed from studies that are adequately powered to determine whether life skills training is beneficial for people with chronic mental health problems.

Abstract
OBJECTIVE Electroconvulsive therapy (ECT) is one of the most effective treatments for severe major depressive disorder. However, after acute-phase treatment and initial remission, relapse rates are significant. Strategies to prolong remission include continuation phase ECT, pharmacotherapy, psychotherapy, or their combinations. This systematic review synthesizes extant data regarding the combined use of psychotherapy with ECT for the treatment of patients with severe major depressive disorder and offers the hypothesis that augmenting ECT with depression-specific psychotherapy represents a promising strategy for future investigation. METHODS The authors performed 2 independent searches in PsychInfo (1806-2009) and MEDLINE (1948-2009) using combinations of the following search terms: Electroconvulsive Therapy (including ECT, ECT therapy, electroshock therapy, EST, and shock therapy) and Psychotherapy (including cognitive behavioral, interpersonal, group, psychodynamic, psychoanalytic, individual, eclectic, and supportive). We included in this review a total of 6 articles (English language) that mentioned ECT and psychotherapy in the abstract and provided a case report, series, or clinical trial. We examined the articles for data related to ECT and psychotherapy treatment characteristics, cohort characteristics, and therapeutic outcome. RESULTS Although research over the past 7 decades documenting the combined use of ECT and psychotherapy is limited, the available evidence suggests that testing this combination has promise and may confer additional, positive functional outcomes. CONCLUSIONS Significant methodological variability in ECT and psychotherapy procedures, heterogeneous patient cohorts, and inconsistent outcome measures prevent strong conclusions; however, existing research supports the need for future investigations of combined ECT and psychotherapy in well-designed, controlled clinical studies. Depression-specific psychotherapy approaches may need special adaptations in view of the cognitive effects of ECT.

Abstract
OBJECTIVE "Michael's Game" is a card game which aims at familiarizing healthcare professionals and patients with cognitive therapy of psychotic symptoms. The present study tests the feasibility and the impact of the intervention in naturalistic settings. METHODS 135 patients were recruited in 11 centres. They were assessed pre- and post-tests with the Beck Cognitive Insight Scale (BCIS) and the Peters Delusion Inventory-21 items (PDI-21). RESULTS Data about 107 patients were included in the entire analyses. Significant improvements were observed on BCIS subscales as well as a reduction of severity of conviction and preoccupation scores on the PDI-21. The intervention has a moderate effect on the PDI-21 preoccupation and conviction as well as the BCIS subscales. Patients who benefit the most from the program are patients who have a low degree of self-reflectiveness and patients who are concomitantly preoccupied by their symptoms. CONCLUSION The present study supports the feasibility and effectiveness of "Michael's Game" in naturalistic settings. PRACTICAL IMPLICATIONS The game seems to be a useful tool for patients with psychotic disorders.

Abstract
BACKGROUND Cognitive behavioural therapy (CBT) is now a recommended treatment for people with schizophrenia. This approach helps to link the person's feelings and patterns of thinking which underpin distress. OBJECTIVES To review the effects of CBT for people with schizophrenia when compared to other psychological therapies. SEARCH STRATEGY We searched the Cochrane Schizophrenia Group Trials Register (March 2010) which is based on regular searches of CINAHL, EMBASE, MEDLINE and PsycINFO. We inspected all references of the selected articles for further relevant trials, and, where appropriate, contacted authors. SELECTION CRITERIA All relevant clinical randomised trials of cognitive behaviour therapy for people with schizophrenia-like illnesses. DATA COLLECTION AND ANALYSIS Studies were reliably selected and assessed for methodological quality. Two reviewers, working independently, extracted data. We analysed dichotomous data on an intention-to-treat basis and continuous data with 65% completion rate are presented. Where possible, for dichotomous outcomes, we estimated a relative risk (RR) with the 95% confidence interval along with the number needed to treat/harm. MAIN RESULTS Twenty-nine papers described 20 trials. Trials were often small and of limited quality. When CBT was compared with other psychosocial therapies no difference was found for outcomes relevant to adverse effect/events (2 RCTs, n=202, RR death 0.57 CI 0.12 to 2.60). Relapse was not reduced over any time period (5 RCTs, n=183, RR in long term 0.91 CI 0.63 to 1.32) nor was rehospitalisation (5 RCTs, n=294, RR in longer term 0.86 CI 0.62 to 1.21). Various global mental state measures failed to show difference (4 RCTs, n=244, RR no important change in mental state 0.84 CI 0.64 to 1.09). More specific measures of mental state failed to show differential effects on positive or negative symptoms of schizophrenia but there may be some longer term effect for affective symptoms (2 RCTs, n=105, MD BDI -6.21 CI -10.81 to -1.61). Few trials report on social functioning or quality of life. Findings do not convincingly favour either interventions (2 RCT, n=103, MD SFS 1.32 CI -4.90 to 7.54; n=37, MD EuroQOL -1.86 CI -19.20 to 15.48). For the outcome of leaving the study early we found no significant advantage when CBT was compared with either non-active control therapies (4 RCTs, n=433, RR 0.88 CI 0.63 to 1.23) or active therapies (6 RCTs, n=339, RR 0.75 CI 0.40 to 1.43) AUTHORS' CONCLUSIONS Trail-based evidence suggests no clear and convincing advantage for cognitive behavioural therapy over other and sometime much less sophisticated therapies for people with schizophrenia.

Abstract
BACKGROUND Insight is increasingly seen as an important variable for study in psychotic illness, particularly in relation to treatment adherence. This study aims to quantify the association of insight with outcome, sociodemographic variables and diagnosis in a large stable patient sample. METHOD Data are from a one-year, open-label, international, multicenter trial (n=670) of long-acting risperidone in adult symptomatically stable patients with schizophrenia or schizoaffective disorder. Psychopathology and insight were quantified using the Positive and Negative Syndrome Scale (PANSS). Patients were assessed at four time points over the year of the study. RESULTS 31.2% of the sample showed clinically significant deficits in insight at baseline. There were no differences based on sex, but significant differences in age and diagnosis, with oldest patients and schizophrenia patients (cf., schizoaffective disorder) showing more deficits. Baseline insight impairment was correlated with change in PANSS score at one year (r=-0.243, p<0.001). Recursive partitioning showed that, of those whose symptoms improved, those whose insight also improved were more likely to complete the trial. CONCLUSIONS Insight is important above and beyond the effects of symptoms for predicting continuation in drug trials. This may have implications for the design and analysis of such trials, as well as suggesting the importance of targeting insight in treatment to increase likelihood of adherence to treatment. There also appear to be small but significant differences in insight based on age and diagnosis within the schizophrenia spectrum.

Abstract
The Schizophrenia Patient Outcomes Research Team (PORT) psychosocial treatment recommendations provide a comprehensive summary of current evidence-based psychosocial treatment interventions for persons with schizophrenia. There have been 2 previous sets of psychosocial treatment recommendations (Lehman AF, Steinwachs DM. Translating research into practice: the Schizophrenia Patient Outcomes Research Team (PORT) treatment recommendations. Schizophr Bull. 1998;24:1-10 and Lehman AF, Kreyenbuhl J, Buchanan RW, et al. The Schizophrenia Patient Outcomes Research Team (PORT): updated treatment recommendations 2003. Schizophr Bull. 2004;30:193-217). This article reports the third set of PORT recommendations that includes updated reviews in 7 areas as well as adding 5 new areas of review. Members of the psychosocial Evidence Review Group conducted reviews of the literature in each intervention area and drafted the recommendation or summary statement with supporting discussion. A Psychosocial Advisory Committee was consulted in all aspects of the review, and an expert panel commented on draft recommendations and summary statements. Our review process produced 8 treatment recommendations in the following areas: assertive community treatment, supported employment, cognitive behavioral therapy, family-based services, token economy, skills training, psychosocial interventions for alcohol and substance use disorders, and psychosocial interventions for weight management. Reviews of treatments focused on medication adherence, cognitive remediation, psychosocial treatments for recent onset schizophrenia, and peer support and peer-delivered services indicated that none of these treatment areas yet have enough evidence to merit a treatment recommendation, though each is an emerging area of interest. This update of PORT psychosocial treatment recommendations underscores both the expansion of knowledge regarding psychosocial treatments for persons with schizophrenia at the same time as the limitations in their implementation in clinical practice settings.

From drugs to deprivation: a Bayesian framework for understanding models of psychosis. Psychopharmacology (Berl) 2009; 206:515-30.

Abstract
INTRODUCTION Various experimental manipulations, usually involving drug administration, have been used to produce symptoms of psychosis in healthy volunteers. Different drugs produce both common and distinct symptoms. A challenge is to understand how apparently different manipulations can produce overlapping symptoms. We suggest that current Bayesian formulations of information processing in the brain provide a framework that maps onto neural circuitry and gives us a context within which we can relate the symptoms of psychosis to their underlying causes. This helps us to understand the similarities and differences across the common models of psychosis. MATERIALS AND METHODS The Bayesian approach emphasises processing of information in terms of both prior expectancies and current inputs. A mismatch between these leads us to update inferences about the world and to generate new predictions for the future. According to this model, what we experience shapes what we learn, and what we learn modifies how we experience things. DISCUSSION This simple idea gives us a powerful and flexible way of understanding the symptoms of psychosis where perception, learning and inference are deranged. We examine the predictions of the cognitive model in light of what we understand about the neuropharmacology of psychotomimetic drugs and thereby attempt to account for the common and the distinctive effects of NMDA receptor antagonists, serotonergic hallucinogens, cannabinoids and dopamine agonists. CONCLUSION By acknowledging the importance of perception and perceptual aberration in mediating the positive symptoms of psychosis, the model also provides a useful setting in which to consider an under-researched model of psychosis-sensory deprivation.

Abstract
The majority of clinical trials of cognitive-behavioral therapy (CBT) for schizophrenia have used individual therapy to target positive symptoms. Promising results have been found, however, for group CBT interventions and other treatment targets like psychosocial functioning. CBT for functioning in schizophrenia is based on a cognitive model of functional outcome in schizophrenia that incorporates dysfunctional attitudes (eg, social disinterest, defeatist performance beliefs) as mediators between neurocognitive impairment and functional outcome. In this report, 18 clinical trials of CBT for schizophrenia that included measures of psychosocial functioning were reviewed, and two-thirds showed improvements in functioning in CBT. The cognitive model of functional outcome was also tested by examining the relationship between social disinterest attitudes and functional outcome in 79 people with schizophrenia randomized to either group cognitive-behavioral social skills training or a goal-focused supportive contact intervention. Consistent with the cognitive model, lower social disinterest attitudes at baseline and greater reduction in social disinterest during group therapy predicted better functional outcome at end of treatment for both groups. However, the groups did not differ significantly with regard to overall change in social disinterest attitudes during treatment, suggesting that nonspecific social interactions during group therapy can lead to changes in social disinterest, regardless of whether these attitudes are directly targeted by cognitive therapy interventions.

Abstract
Paranoid delusions are associated with an abnormal attributional style that serves the function of preventing the activation of latent discrepancies between self-perceptions and self-ideals at the expense of contributing to the paranoid patient's negative perceptions of the intentions of others. In this case study we describe a therapeutic strategy designed to allow a patient suffering from persecutory delusions to re-attribute negative life experiences to situational causes rather than to a conspiracy directed towards himself. It was hypothesized that no resistance was encountered from the patiet because no attempt was made to re-attribute negative events to internal causes. A reduction in paranoid ideation, which was maintained at follow-up, was accompanied by changes on formal measures of attributions. The implications of these findings for cognitive models of paranoid ideation, and for the development of interventions for deluded patients are discussed.

Abstract
A randomized controlled trial of a new intervention based on motivational interviewing and cognitive approaches to psychosis (Compliance Therapy) has shown improvements in insight, attitudes to medication and compliance in an unselected sample of consecutively admitted patients with acute psychotic disorders. In the introduction, previous research focusing on cognitive interventions in psychosis and systematically tested psychoeducational approaches to compliance are reviewed. The content of our intervention is described with examples of the principal techniques used, together with a description of the progress of therapy in two individual cases. We conclude that the intervention is eminently applicable in the typical clinical setting.

Abstract
Auditory hallucinations comprise the most common symptoms of schizophrenia. Although antipsychotic medications are helpful, in that they reduce symptoms and the likelihood of relapse, many patients do not benefit from their use. In recent years, psychological interventions have been developed in the West to help such patients. However, cross-cultural studies have shown that the nature and form of auditory hallucinations are affected by cultural differences, suggesting that a patient's cultural background needs to be considered when applying psychological methods. In this study, three schizophrenic patients from Saudi Arabia whose auditory hallucinations persisted despite the administration of antipsychotic medications were given a modified psychological intervention designed to alter the characteristics and content of their hallucinations. The modifications included an emphasis on Islamic doctrine and religion. Two patients benefited from the interventions. The third patient was reluctant to engage with the therapist, probably because the content of his voices was benign. The importance of such modifications when employing psychological intervention for patients from non-Western backgrounds is discussed.

Abstract
A number of psychosocial treatments are available for persons with schizophrenia that include social skills training, cognitive behavioral therapy, cognitive remediation, and social cognition training. These treatments are reviewed and discussed in terms of how they address key components of functional recovery such as symptom stability, independent living, work functioning, and social functioning. We also review findings on the interaction between pharmacological and psychosocial treatments and discuss future directions in pharmacological treatment of schizophrenia. Overall, these treatments provide a range of promising approaches to helping patients achieve better outcomes far beyond symptom stabilization.

Abstract
BACKGROUND Guidance in the United States and United Kingdom has included cognitive behavior therapy for psychosis (CBTp) as a preferred therapy. But recent advances have widened the CBTp targets to other symptoms and have different methods of provision, eg, in groups. AIM To explore the effect sizes of current CBTp trials including targeted and nontargeted symptoms, modes of action, and effect of methodological rigor. METHOD Thirty-four CBTp trials with data in the public domain were used as source data for a meta-analysis and investigation of the effects of trial methodology using the Clinical Trial Assessment Measure (CTAM). RESULTS There were overall beneficial effects for the target symptom (33 studies; effect size = 0.400 [95% confidence interval [CI] = 0.252, 0.548]) as well as significant effects for positive symptoms (32 studies), negative symptoms (23 studies), functioning (15 studies), mood (13 studies), and social anxiety (2 studies) with effects ranging from 0.35 to 0.44. However, there was no effect on hopelessness. Improvements in one domain were correlated with improvements in others. Trials in which raters were aware of group allocation had an inflated effect size of approximately 50%-100%. But rigorous CBTp studies showed benefit (estimated effect size = 0.223; 95% CI = 0.017, 0.428) although the lower end of the CI should be noted. Secondary outcomes (eg, negative symptoms) were also affected such that in the group of methodologically adequate studies the effect sizes were not significant. CONCLUSIONS As in other meta-analyses, CBTp had beneficial effect on positive symptoms. However, psychological treatment trials that make no attempt to mask the group allocation are likely to have inflated effect sizes. Evidence considered for psychological treatment guidance should take into account specific methodological detail.

Abstract
BACKGROUND Most people with schizophrenia have a cyclical pattern of illness characterised by remission and relapses. The illness can reduce the ability of self-care and functioning and can lead to the illness becoming chronic and disabling. Rehabilitation is one of the important parts of treatments. Life skills programmes, emphasising the needs associated with independent functioning, are often a part of the rehabilitation process. These programmes, therefore, have been developed to enhance independent living and the quality of life for people with schizophrenia living in the community. OBJECTIVES To review the effectiveness of life skills programmes with standard care or other comparable therapies for people with chronic mental health problems. SEARCH STRATEGY We searched the Cochrane Schizophrenia Group Trials Register (May 2007) which is based on regular searches of BIOSIS, CENTRAL, CINAHL, EMBASE, MEDLINE and PsycINFO. Hand searches and scrutiny of references supplemented this process. We inspected references of all identified studies for further trials. SELECTION CRITERIA We included all relevant randomised or quasi-randomised controlled trials for life skills programmes versus other comparable therapies or standard care involving people with serious mental illnesses. DATA COLLECTION AND ANALYSIS We extracted data independently. For dichotomous data we calculated relative risks (RR) and their 95% confidence intervals (CI) on an intention-to-treat basis, based on a random effects model. We calculated numbers needed to treat/harm (NNT/NNH) where appropriate. For continuous data, we calculated weighted mean differences (WMD) again based on a random effects model. MAIN RESULTS We included four randomised controlled trials with a total of 318 participants. These evaluated life skills programmes versus standard care, or support group. We found no significant difference in life skills performance between people given life skills training and standard care (Patterson 2003, n=32, WMD -1.10 CI -7.8 to 5.6). Life skills training did not improve or worsen study retention (n=60, 2 RCTs, RR 1.16 CI 0.4 to 3.4). We found no significant difference in PANSS positive, negative or total scores between life skills intervention and standard care. Depression scores (HAM-D) did not reveal any significant difference between groups (Patterson 2003, n=32, WMD -0.70 CI -4.1 to 2.7). We found quality of life scores to be equivocal between participants given life skills training (Patterson 2003, n=32, WMD -0.02 CI -0.1 to 0.03) and standard care. Life skills compared with support groups also did not reveal any significant differences in PANSS scores, quality of life, or social performance skills (Patterson 2006, n=158, WMD -0.90 CI -3.4 to 1.6). AUTHORS' CONCLUSIONS Currently there is no good evidence to suggest life skills programmes are effective for people with chronic mental illnesses. More robust data are needed from studies that are adequately powered to determine whether life skills training is beneficial for people with chronic mental health problems.

Abstract
Research meta-analyses have found that cognitive-behavioral therapy (CBT) is beneficial for persistent symptoms of schizophrenia. This review describes and updates the evidence base for this statement. A review of the existing literature (Medline, PsychInfo, and Embase) was carried out according to the guidelines for systematic reviews. Based on the findings of this review, the updated conclusion is that CBT has emerged as an effective adjuvant to antipsychotic medication in the treatment of persistent symptoms of schizophrenia. Studies of the use of CBT in the prodromal phase of psychosis and in combination with family therapy are currently underway.

Abstract
BACKGROUND Supportive therapy is often used in everyday clinical care and in evaluative studies of other treatments. OBJECTIVES To estimate the effects of supportive therapy for people with schizophrenia. SEARCH STRATEGY We searched the Cochrane Schizophrenia Group's register of trials (January 2004), supplemented by manual reference searching and contact with authors of relevant reviews or studies. SELECTION CRITERIA All randomised trials involving people with schizophrenia and comparing supportive therapy with any other treatment or standard care. DATA COLLECTION AND ANALYSIS We reliably selected studies, quality rated these and extracted data. For dichotomous data, we estimated the relative risk (RR) fixed effect with 95% confidence intervals (CI). Where possible, we undertook intention-to-treat analyses. For statistically significant results, we calculated the number needed to treat/harm (NNT/H). We estimated heterogeneity (I-square technique) and publication bias. MAIN RESULTS We included 21 relevant studies. We found no significant differences in the primary outcomes between supportive therapy and standard care. There were, however, significant differences favouring other psychological or psychosocial treatments over supportive therapy. These included hospitalisation rates (3 RCTs, n=241, RR 2.12 CI 1.2 to 3.6, NNT 8) but not relapse rates (5 RCTs, n=270, RR 1.18 CI 0.9 to 1.5). We found that the results for general functioning significantly favoured cognitive behavioural therapy compared with supportive therapy in the short (1 RCT, n=70, WMD -9.50 CI -16.1 to -2.9), medium (1 RCT, n=67, WMD -12.6 CI -19.4 to -5.8) and long term (2 RCTs, n=78, SMD -0.50 CI -1.0 to -0.04), but the clinical significance of these findings based on few data is unclear. Participants were less likely to be satisfied with care if receiving supportive therapy compared with cognitive behavioural treatment (1 RCT, n=45, RR 3.19 CI 1.0 to 10.1, NNT 4 CI 2 to 736). The results for mental state and symptoms were unclear in the comparisons with other therapies. No data were available to assess the impact of supportive therapy on engagement with structured activities. AUTHORS' CONCLUSIONS There are insufficient data to identify a difference in outcome between supportive therapy and standard care. There are several outcomes, including hospitalisation and general mental state, indicating advantages for other psychological therapies over supportive therapy but these findings are based on a few small studies. Future research would benefit from larger trials that use supportive therapy as the main treatment arm rather than the comparator.

Abstract
Patients with schizophrenia are at high risk of suicide. Cognitive behavior therapy (CBT) has been shown to reduce symptoms in schizophrenia. This study examines whether CBT also changes the level of suicidal ideation in patients with schizophrenia compared to a control group. Ninety ambulatory patients with symptoms of schizophrenia resistant to conventional antipsychotic medication were randomized to CBT or befriending. They were assessed using the Comprehensive Psychopathological Rating Scale, including a rating of suicidal ideation at baseline, post intervention, and after 9 months. Post-hoc analysis revealed that CBT provided significant reductions in suicidal ideation at the end of therapy, and sustained at the follow-up. Further research is required to substantiate these findings and determine the process and mechanisms through which this reduction is achieved.

Abstract
This study examines the level of expressed emotion (EE) and burnout in staff caring for people with learning disabilities on a medium secure unit. The study aims to develop a baseline measure of EE and burnout in staff on the unit to be used for future service evaluation and to underpin interventions in the developing service based on psychosocial interventions. Ten staff participated in an audiotaped interview and completed a questionnaire. The Five Minute Speech Sample and Maslach Burnout Inventory were completed. High EE was evident in 31% of responses based on critical comments and negative relationships. Expressed emotion was higher in male staff and in Health Care Support Workers. No staff met all components for high burnout, but low personal accomplishment, high emotional exhaustion and high depersonalization were evident for some staff. There is evidence of high EE and some elements of high burnout within the staff team. A significant relationship was found between the level of high EE and the depersonalization element of burnout.

Abstract
OBJECTIVE Cognitive-behavioural therapy (CBT) has proved effective in treating delusions, both in schizophrenia and delusional disorder (DD). Clinical trials of DD have mostly compared CBT with either treatment as usual, no treatment, or a wait-list control. This current study aimed to assess patients with DD who received CBT, compared with an attention placebo control (APC) group. METHOD Twenty-four individuals with DD were randomly allocated into either CBT or APC groups for a 24-week treatment period. Patients were diagnosed on the basis of structured clinical interviews for mental disorders and the Maudsley Assessment of Delusion Schedule (MADS). RESULTS Completers in both groups (n = 11 for CBT; n = 6 for APC) showed clinical improvement on the MADS dimensions of Strength of Conviction, Insight, Preoccupation, Systematization, Affect Relating to Belief, Belief Maintenance Factors, and Idiosyncrasy of Belief. CONCLUSION When compared with APC, CBT produced more impact on the MADS dimensions for Affect Relating to Belief, Strength of Conviction, and Positive Actions on Beliefs.

Abstract
BACKGROUND Supportive therapy is often used in everyday clinical care and in evaluative studies of other treatments. OBJECTIVES To estimate the effects of supportive therapy for people with schizophrenia. SEARCH STRATEGY We searched the Cochrane Schizophrenia Group's register of trials (January 2004), supplemented by manual reference searching and contact with authors of relevant reviews or studies. SELECTION CRITERIA All randomised trials involving people with schizophrenia and comparing supportive therapy with any other treatment or standard care. DATA COLLECTION AND ANALYSIS We reliably selected studies, quality rated these and extracted data. For dichotomous data, we estimated the relative risk (RR) fixed effect with 95% confidence intervals (CI). Where possible, we undertook intention-to-treat analyses. For statistically significant results, we calculated the number needed to treat/harm (NNT/H). We estimated heterogeneity (I-square technique) and publication bias. MAIN RESULTS We included 21 relevant studies. We found no significant differences in the primary outcomes between supportive therapy and standard care. There were, however, significant differences favouring other psychological or psychosocial treatments over supportive therapy. These included hospitalisation rates (3 RCTs, n=241, RR 2.12 CI 1.2 to 3.6, NNT 8) but not relapse rates (5 RCTs, n=270, RR 1.18 CI 0.9 to 1.5). We found that the results for general functioning significantly favoured cognitive behavioural therapy compared with supportive therapy in the short (1 RCT, n=70, WMD -9.50 CI -16.1 to -2.9), medium (1 RCT, n=67, WMD -12.6 CI -19.4 to -5.8) and long term (2 RCTs, n=78, SMD -0.50 CI -1.0 to -0.04), but the clinical significance of these findings based on few data is unclear. Participants were less likely to be satisfied with care if receiving supportive therapy compared with cognitive behavioural treatment (1 RCT, n=45, RR 3.19 CI 1.0 to 10.1, NNT 4 CI 2 to 736). The results for mental state and symptoms were unclear in the comparisons with other therapies. No data were available to assess the impact of supportive therapy on engagement with structured activities.

There are several outcomes, including hospitalisation and general mental state, indicating advantages for other psychological therapies over supportive therapy but these findings are based on a few small studies.

Abstract
The Illness Management and Recovery (IMR) program was developed based on a comprehensive review of research on teaching illness self-management strategies to clients with schizophrenia and other severe mental illnesses and "packaged" in a resource kit to facilitate dissemination. Despite growing dissemination of this program, it has not yet been empirically validated. This article describes the development and theoretical underpinnings of the IMR program and presents pilot data from the United States and Australia (N = 24, 88% schizophrenia or schizoaffective) on the effects of individual-based and group-based treatment over the 9-month program and over a 3-month follow-up. High satisfaction was reported by participants. Strong improvements over treatment and at follow-up were found in clients' self-reported effectiveness in coping with symptoms and clinicians' reports of global functioning and moderate improvements in knowledge about mental illness, distress related to symptoms, hope, and goal orientation. These findings support the feasibility and promise of the IMR program and point to the need for controlled research to rigorously evaluate its effects.

Abstract
Delusional disorders are rare, but psychoses with prominent and persistent delusions are less so. A small but significant association between psychosis and violence is often mediated by delusions in such illnesses. Traditionally, delusions have been viewed as "incorrigible", but there is evidence that they change over time. During development of a scale for measuring delusions, it was found that people who acted violently on their "most important" delusion were more likely to have modified that belief after a mild form of challenge to it. When cognitive-behaviour therapy (CBT) is used for schizophrenia, attempts to modify psychotic symptoms are generally included. Could studies of CBT provide further information about possible risks of social interactions about delusions?In the UK, 2000 people with schizophrenia have been in randomized controlled trials of CBT with a goal of symptom modification. These studies were examined for evidence of violence during the treatment. There was none. Given the period prevalence of violence among people with psychosis, this is surprising. In these studies, however, both challenge to delusions and change in them was minimal and in the context of a safe clinical relationship. Challenge to delusions may, however, occur in a variety of social situations. There are no systematic data on lay challenge to them, but it seems likely that some in the sufferer's social circle will do so vigorously. Relatives, friends, and acquaintances are the people most vulnerable to the most serious violence by someone with psychosis. Study of how people interact in these circumstances and whether their interactions are relevant to modification of delusions would be worthwhile. Could those close to a sufferer learn skills for responding to such pathological beliefs that could be protective against violence, perhaps derived from the principles of CBT?

Abstract
Many patients with schizophrenia have psychological distress and receive some form of psychotherapy. Several different psychotherapeutic approaches for schizophrenia have been developed and studied. Of these approaches, cognitive behavior therapy has the strongest evidence base and has shown benefit for symptom reduction in outpatients with residual symptoms. In addition to cognitive behavior therapy, other approaches include compliance therapy, personal therapy, acceptance and commitment therapy, and supportive therapy. Although usually studied as distinct approaches, the therapies overlap with each other in their therapeutic elements. As psychotherapy for schizophrenia further evolves, it will likely be informed by other psychosocial interventions used with this clinical population. In particular, techniques of remediating cognitive deficits, teaching behavioral skills, and educating about schizophrenia may be incorporated with psychotherapy. Future research may also consider three different goals of psychotherapy with this population: to provide emotional support, to enhance skills for functional recovery, and to alter the underlying illness process.

Abstract
BACKGROUND Despite the effectiveness of anti-psychotic pharmacotherapy, residual hallucinations and delusions do not completely resolve in some medicated patients. Additional cognitive behavioral therapy (CBT) seems to improve the management of positive symptoms. Despite promising results, the efficacy of CBT is still unclear. The present study addresses this issue taking into account a number of newly published controlled studies. METHOD Fourteen studies including 1484 patients, published between 1990 and 2004 were identified and a meta-analysis of their results performed. RESULTS Compared to other adjunctive measures, CBT showed significant reduction in positive symptoms and there was a higher benefit of CBT for patients suffering an acute psychotic episode versus the chronic condition (effect size of 0.57 vs. 0.27). DISCUSSION CBT is a promising adjunctive treatment for positive symptoms in schizophrenia spectrum disorders. However, a number of potentially modifying variables have not yet been examined, such as therapeutic alliance and neuropsychological deficits.

Abstract
Older people with chronic schizophrenia are a numerically small but important group with complex clinical and service needs. Along with a reduction in positive schizophrenic symptoms with increasing age, a majority suffer from negative symptoms, cognitive deficits, depression, side effects due to long-term use of antipsychotics and co-morbid medical problems. They may have social disabilities making them vulnerable to poverty, isolation and poor quality of life. Evidence suggests that judicious use of antipsychotics combined with psychotherapy and psychosocial interventions are effective. There are shortcomings in the standard of both hospital and community care, and the cost implications of providing adequate services are high.
