Family intervention for schizophrenia

Psychoeducation for siblings of people with severe mental illness

BACKGROUND

Many people with severe mental illness (SMI) have siblings. Siblings are often both natural agents to promote service users' recovery and vulnerable to mental ill health due to the negative impact of psychosis within the family. Despite a wealth of research evidence supporting the effectiveness of psychoeducation for service users with SMI and their family members, in reducing relapse and promoting compliance with treatment, siblings remain relatively invisible in clinical service settings as well as in research studies. If psychoeducational interventions target siblings and improve siblings' knowledge, coping with caring and overall wellbeing, they could potentially provide a cost-effective option for supporting siblings with resulting benefits for service users' outcomes.

OBJECTIVES

To assess the effectiveness of psychoeducation compared with usual care or any other intervention in promoting wellbeing and reducing distress of siblings of people affected by SMI.The secondary objective was, if possible, to determine which type of psychoeducation is most effective.

SEARCH METHODS

We searched the Cochrane Schizophrenia Group Trials Register and screened the reference lists of relevant reports and reviews (12th November 2013). We contacted trial authors for unpublished and specific data on siblings' outcomes.

SELECTION CRITERIA

All relevant randomised controlled trials focusing on psychoeducational interventions targeting siblings of all ages (on their own or amongst other family members including service users) of individuals with SMI, using any means and formats of delivery, i.e. individual (family), groups, computer-based.

DATA COLLECTION AND ANALYSIS

Two review authors independently screened the abstracts and extracted data and two other authors independently checked the screening and extraction process. We contacted authors of trials to ascertain siblings' participation in the trials and seek sibling-specific data in those studies where siblings' data were grouped together with other participants' (most commonly other family members'/carers') outcomes. We calculated the risk difference (RD), its 95% confidence interval (CI) on an intention-to-treat basis. We presented continuous data using the mean difference statistic (MD) and 95% CIs. We assessed risk of bias for the included study and rated quality of evidence using Grading of Recommendations Assessment, Development and Evaluation (GRADE).

MAIN RESULTS

We found 14 studies that included siblings amongst other family members in receipt of psychoeducational interventions. However, we were only able to include one small trial with relevant and available data (n = 9 siblings out of n = 84 family member/carer-participants) comparing psychoeducational intervention with standard care in a community care setting, over a duration of 21 months. There was insufficient evidence to determine the effects of psychoeducational interventions compared with standard care on 'siblings' quality of life' (n = 9, MD score 3.80 95% CI -0.26 to 7.86, low quality of evidence), coping with (family) burden (n = 9, MD -8.80 95% CI -15.22 to -2.34, low quality of evidence). No sibling left the study early by one year (n = 9, RD 0.00 CI -0.34 to 0.34, low quality of evidence). Low quality and insufficient evidence meant we were unable to determine the effects of psychoeducational interventions compared with standard care on service users' global mental state (n = 9, MD -0.60 CI -3.54 to 2.38, low quality of evidence), their frequency of re-hospitalisation (n = 9, MD -0.70 CI -2.46 to 1.06, low quality of evidence) or duration of inpatient stay (n = 9, MD -2.60 CI -6.34 to 1.14, low quality of evidence), whether their siblings received psychoeducation or not. No study data were available to address the other primary outcomes: 'siblings' psychosocial wellbeing', 'siblings' distress' and adverse effects.

AUTHORS' CONCLUSIONS

Most studies evaluating psychoeducational interventions recruited siblings along with other family members. However, the proportion of siblings in these studies was low and outcomes for siblings were not reported independently from those of other types of family members. Indeed, only data from one study with nine siblings were available for the review. The limited study data we obtained provides no clear good quality evidence to indicate psychoeducation is beneficial for siblings' wellbeing or for clinical outcomes of people affected by SMI. More randomised studies are justified and needed to understand the role of psychoeducation in addressing siblings' needs for information and support.

Family influence in recovery from severe mental illness

The aim of this study was to investigate the perceived influence of family on recovery from severe mental illness. 54 semi-structured interviews were conducted with a diverse sample of people with severe mental illness living in Montreal. Results indicated that family both facilitated and impeded recovery processes. Specifically, family facilitated recovery through providing (a) moral support, (b) practical support and (c) motivation to recover. However family impeded recovery through (a) acting as a stressor, (b) displaying stigma and lack of understanding, and (c) forcing hospitalization. The study indicates the importance of family psychoeducation in promoting recovery.

Systematic review of feasibility and acceptability of psychosocial interventions for schizophrenia in low and middle income countries

BACKGROUND

In low and middle income countries there is evidence to suggest effectiveness of community-based psychosocial interventions for schizophrenia. Many psychosocial interventions have however been conceptualized in high income countries and assessing their feasibility and acceptability in low and middle income countries is pertinent and the objective of this review.

METHODS

Six databases were searched using search terms (i) "Schizophrenia"; (ii) "Low and middle income or developing countries" and (iii) "Psychosocial interventions". Abstracts identified were extracted to an EndNote Database. Two authors independently reviewed abstracts according to defined inclusion and exclusion criteria. Full papers were accessed of studies meeting these criteria, or for which more information was needed to include or exclude them. Data were extracted from included studies using a predesigned data extraction form. Qualitative synthesis of qualitative and quantitative data was conducted.

RESULTS

14 037 abstracts were identified through searches. 196 full articles were reviewed with 17 articles meeting the inclusion criteria. Little data emerged on feasibility. Barriers to feasibility were noted including low education levels of participants, unavailability of caregivers, and logistical issues such as difficulty in follow up of participants. Evidence of acceptability was noted in high participation rates and levels of satisfaction with interventions.

CONCLUSIONS

While there is preliminary evidence to suggest acceptability of community-based psychosocial interventions for schizophrenia in low and middle income countries, evidence for overall feasibility is currently lacking. Well-designed intervention studies incorporating specific measures of acceptability and feasibility are needed.

Schizophrenia interventions in Vietnam: primary results from a cost-effectiveness study

Schizophrenia is a highly disabling mental health disorder that imposes a considerable economic burden on a health care system. This paper aimed to examine the cost and effectiveness of alternative pharmaceutical interventions and the effects of family intervention (FI) for schizophrenia from the government perspective in order to introduce the most cost-effective intervention applicable to Vietnam. A Markov model was developed to estimate costs and health outcome over patients' lifetimes when using typical and atypical antipsychotic drugs, alone or in combination with family intervention. Health outcome was measured in terms of disability-adjusted life years averted. Monte Carlo simulation was used for uncertainty analysis. According to our findings, interventions using typical or atypical drugs combined with FI were found to be the most effective and least costly compared to a 'do-nothing' scenario. Interventions using atypical drugs alone were estimated to be much less favourable due to a considerably higher cost. This is a very first attempt on cost-effectiveness analysis of interventions for schizophrenia in Vietnam, and recommendations are made for future research to determine the most cost-effective intervention.

A randomized clinical trial to test the efficacy of a family-focused, culturally informed therapy for schizophrenia

Research strongly suggests that family interventions can benefit patients with schizophrenia, yet current interventions often fail to consider the cultural context and spiritual practices that may make them more effective and relevant to ethnic minority populations. We have developed a family focused, culturally informed treatment for schizophrenia (CIT-S) patients and their caregivers to address this gap. Sixty-nine families were randomized to either 15 sessions of CIT-S or to a 3-session psychoeducation (PSY-ED) control condition. Forty-six families (66.7%) completed the study. The primary aim was to test whether CIT-S would outperform PSY-ED in reducing posttreatment symptom severity (controlling for baseline symptoms) on the Brief Psychiatric Rating Scale. Secondary analyses were conducted to test whether treatment efficacy would be moderated by ethnicity and whether patient-therapist ethnic match would relate to efficacy and patient satisfaction with treatment. Patients included 40 Hispanic/Latinos, 14 Whites, 11 Blacks, and 4 patients who identified as "other." In line with expectations, results from an ANCOVA indicated that patients assigned to the CIT-S condition had significantly less severe psychiatric symptoms at treatment termination than did patients assigned to the PSY-ED condition. Patient ethnicity and patient-therapist ethnic match (vs. mismatch) did not relate to treatment efficacy or satisfaction with the intervention. Results suggest that schizophrenia may respond to culturally informed psychosocial interventions. The treatment appears to work equally well for Whites and minorities alike. Follow-up research with a matched length control condition is needed. Further investigation is also needed to pinpoint specific mechanisms of change.

How much do we know about schizophrenia and how well do we know it? Evidence from the Schizophrenia Library

BACKGROUND

True findings about schizophrenia remain elusive; many findings are not replicated and conflicting results are common. Well-conducted systematic reviews have the ability to make robust, generalizable conclusions, with good meta-analyses potentially providing the closest estimate of the true effect size. In this paper, we undertake a systematic approach to synthesising the available evidence from well-conducted systematic reviews on schizophrenia.

METHOD

Reviews were identified by searching Medline, EMBASE, CINAHL, Current Contents and PsycINFO. The decision to include or exclude reviews, data extraction and quality assessments were conducted in duplicate. Evidence was graded as high quality if reviews contained large samples and robust results; and as moderate quality if reviews contained imprecision, inconsistency, smaller samples or study designs that may be prone to bias.

RESULTS

High- and moderate-quality evidence shows that numerous psychosocial and biomedical treatments are effective. Patients have relatively poor cognitive functioning, and subtle, but diverse, structural brain alterations, altered electrophysiological functioning and sleep patterns, minor physical anomalies, neurological soft signs, and sensory alterations. There are markers of infection, inflammation or altered immunological parameters; and there is increased mortality from a range of causes. Risk for schizophrenia is increased with cannabis use, pregnancy and birth complications, prenatal exposure to Toxoplasma gondii, childhood central nervous system viral infections, childhood adversities, urbanicity and immigration (first and second generation), particularly in certain ethnic groups. Developmental motor delays and lower intelligence quotient in childhood and adolescence are apparent.

CONCLUSIONS

We conclude that while our knowledge of schizophrenia is very substantial, our understanding of it remains limited.

Merging evidence-based psychosocial interventions in schizophrenia

Psychosocial interventions are an essential part of the treatment for people with severe mental illness such as schizophrenia. The criteria regarding what makes an intervention “evidence-based” along with a current list of evidence-based interventions are presented. Although many evidence-based interventions exist, implementation studies reveal that few, if any, are ever implemented in a given setting. Various theories and approaches have been developed to better understand and overcome implementation obstacles. Among these, merging two evidence-based interventions, or offering an evidence-based intervention within an evidence-based service, are increasingly being reported and studied in the literature. Five such merges are presented, along with their empirical support: cognitive behavior therapy (CBT) with skills training; CBT and family psychoeducation; supported employment (SE) and skills training; SE and cognitive remediation; and SE and CBT.

Treatment resistant schizophrenia: a comprehensive survey of randomised controlled trials

BACKGROUND

Schizophrenia is a common serious mental health condition which has significant morbidity and financial consequences. The mainstay of treatment has been antipsychotic medication but one third of people will have a 'treatment resistant' and most disabling and costly illness. The aim of this survey was to produce a broad overview of available randomised evidence for interventions for people whose schizophrenic illness has been designated 'treatment resistant'.

METHOD

We searched the Cochrane Schizophrenia Group's comprehensive Trials Register, selected all relevant randomised trials and, taking care not to double count, extracted the number of people randomised within each study. Finally we sought relevant reviews on the Cochrane Library and investigated how data on this subgroup of people had been presented.

RESULTS

We identified 542 relevant papers based on 268 trials (Average size 64.8 SD 61.6, range 7-526, median 56 IQR 47.3, mode 60). The most studied intervention is clozapine with 82 studies (total n = 6299) comparing it against other anti-psychotic medications. Cognitive behavioural therapy (CBT), electroconvulsive therapy (ECT), or transcranial magnetic stimulation (TMS) supplementing a standard care and risperidone supplementation of clozapine has also been extensively evaluated within trials. Many approaches, however, were clearly under researched. There were only four studies investigating combinations of non-clozapine antipsychotics. Only two psychological approaches (CBT and Family Rehabilitation Training) had more than two studies. Cochrane reviews rarely presented data specific to this important clinical sub-group.

CONCLUSIONS

This survey provides a broad taxonomy of how much evaluative research has been carried out investigating interventions for people with treatment resistant schizophrenia. Over 280 trials have been undertaken but, with a few exceptions, most treatment approaches--and some in common use--have only one or two relevant but small trials. Too infrequently the leading reviews fail to highlight the paucity of evidence in this area--as these reviews are maintained this shortcoming should be addressed.

A review on schizophrenia and relapse--a quest for user-friendly psychopharmacotherapy

OBJECTIVE

Schizophrenia in general is notoriously associated with relapses rendering the illness progressive to worse outcomes, a concept of which is compatible with neurotoxicity. Therefore, relapse prevention is of utmost clinical relevance.

METHODS

In this review, we aim to put relapse into clinical context in the realm of natural history of, or heterogeneity in, schizophrenia and summarize risk factors of relapse. We discuss how to effectively 'define' relapse in schizophrenia and recent meta-analytic studies on this topic to highlight the importance of continuous antipsychotic treatment.

RESULTS

The following issues emerged: 'How low maintenance antipsychotic dosage could be?’, 'How extended dosing could be?’, 'Who could be successfully withdrawn from antipsychotics?’ and 'How relapse could be defined in the first place?’ The question in particular is how better to deliver antipsychotics at the lowest possible, whereby dose and dosing interval are relevant. While ongoing antipsychotic treatment is the rule, recent works are pointing to a possibility of lower dosage in the maintenance phase of the illness.

CONCLUSIONS

Bearing in mind that suboptimal adherence and withdrawal from antipsychotics are an established and unequivocal risk factor for relapse, further investigations are certainly needed to explore user-friendly manner of psychopharmacotherapy to prevent relapse in schizophrenia.

Consumer experience of formal crisis-response services and preferred methods of crisis intervention

The manner in which people with mental illness are supported in a crisis is crucial to their recovery. The current study explored mental health consumers' experiences with formal crisis services (i.e. police and crisis assessment and treatment (CAT) teams), preferred crisis supports, and opinions of four collaborative interagency response models. Eleven consumers completed one-on-one, semistructured interviews. The results revealed that the perceived quality of previous formal crisis interventions varied greatly. Most participants preferred family members or friends to intervene. However, where a formal response was required, general practitioners and mental health case managers were preferred; no participant wanted a police response, and only one indicated a preference for CAT team assistance. Most participants welcomed collaborative crisis interventions. Of four collaborative interagency response models currently being trialled internationally, participants most strongly supported the Ride-Along Model, which enables a police officer and a mental health clinician to jointly respond to distressed consumers in the community. The findings highlight the potential for an interagency response model to deliver a crisis response aligned with consumers' preferences.

Qualitative investigation of targets for and barriers to interventions to prevent psychosis relapse

BACKGROUND

Early signs based relapse prevention interventions for psychosis show promise. In order to examine how they might be improved we sought to better understand the early relapse process, service users' abilities to identify early signs, and any potential facilitators and barriers to early signs interventions.

METHODS

Data from in-depth interviews with a convenience sample of service users with psychosis varying in gender, age, duration of mental health problems, and time since last relapse were analysed using a thematic approach. Interview transcripts were coded inductively and relationships between emerging themes were examined by the research team to provide a thorough synthesis of the data.

RESULTS

Three central themes emerged from the analysis: 1) recognising risk factors (how risk factors were identified and linked to relapse, and reactions to such risk factors); 2) identifying early signs (issues related to both recognising and recalling signs of relapse); 3) reacting to deterioration (participants' thoughts and feelings in response to early signs, including help seeking and its challenges).

CONCLUSIONS

There was considerable variation in the attention participants had paid to pre-relapse signs, the ease with which they were able to recall them, and their reactions to them. For many, there were substantial barriers to help seeking from services. A family or friend confidant was an important means of assistance, although the supportive presence of significant others was not always available. Based on these results, a number of recommendations about facilitating service users' recognition of early signs and targeting potential accelerants of relapse are made.

[Evidence-based interventions in psychiatric rehabilitation: which ones should we prioritized and why?]

OBJECTIVE

This critical literature review describes current evidence-based psychiatric rehabilitation interventions.

METHOD

A brief description of recent meta-analyses and (or) literature reviews is presented for each targeted intervention, along with their revelance for psychiatric rehabilitation and their limits.

RESULTS

The interventions presented include: family interventions, cognitive-behavioural therapy for psychosis, social skills training, cognitive remediation, integrated treatment for substance misuse and mental disorders, and supported employment programs.

CONCLUSIONS

The psychiatric rehabilitation interventions presented in this article not only are based on empirical evidence but also offer clinical tools support the recovery of people with a severe mental illness.

Family intervention (brief) for schizophrenia

BACKGROUND

Supportive, positive family environments have been shown to improve outcomes for patients with schizophrenia in contrast with family environments that express high levels of criticism, hostility, or over-involvement, which have poorer outcomes and have more frequent relapses. Forms of psychosocial intervention, designed to promote positive environments and reduce these levels of expressed emotions within families, are now widely used.

OBJECTIVES

To assess the effects of brief family interventions for people with schizophrenia or schizophrenia-like conditions.

SEARCH METHODS

We searched the Cochrane Schizophrenia Group Trials Register (July 2012), which is based on regular searches of CINAHL, EMBASE, MEDLINE and PsycINFO. We inspected references of all identified studies for further trials. We contacted authors of trials for additional information.

SELECTION CRITERIA

All relevant randomised studies that compared brief family-oriented psychosocial interventions with standard care, focusing on families of people with schizophrenia or schizoaffective disorder were selected.

DATA COLLECTION AND ANALYSIS

We reliably selected studies, quality assessed them and extracted data. For binary outcomes, we calculated standard estimates of risk ratio (RR) and their 95% confidence intervals (CI). For continuous outcomes, we estimated a mean difference (MD) between groups and their 95% CIs. We used GRADE to assess quality of evidence for main outcomes of interest and created a 'Summary of findings' table. We assessed risk of bias for included studies.

MAIN RESULTS

Four studies randomising 163 people could be included in the review. It is not clear if brief family intervention reduces the utilisation of health services by patients, as most results are equivocal at long term and only one study reported data for the primary outcomes of interest of hospital admission (n = 30, 1 RCT, RR 0.50, 95% CI 0.22 to 1.11, very low quality evidence). Data for relapse are also equivocal by medium term (n = 40, 1 RCT, RR 0.50, 95% CI 0.10 to 2.43, low quality evidence). However, data for the family outcome of understanding of family member significantly favoured brief family intervention (n = 70, 1 RCT, MD 14.90, 95% CI 7.20 to 22.60, very low quality evidence). No study reported data for other outcomes of interest including days in hospital; adverse events; medication compliance; quality of life or satisfaction with care; or any economic outcomes.

AUTHORS' CONCLUSIONS

The findings of this review are not outstanding due to the size and quality of studies providing data; the analysed outcomes were also minimal, with no meta-analysis possible. All outcomes in the 'Summary of findings' table were rated low or very low quality evidence. However, the importance of brief family intervention should not be dismissed outright, with the present state of demand and resources available. The designs of such brief interventions could be modified to be more effective with larger studies, which may then have enough power to inform clinical practice.

Familiarity and face emotion recognition in patients with schizophrenia

OBJECTIVE

To assess the emotion recognition in familiar and unknown faces in a sample of schizophrenic patients and healthy controls.

METHODS

Face emotion recognition of 18 outpatients diagnosed with schizophrenia (DSM-IVTR) and 18 healthy volunteers was assessed with two Emotion Recognition Tasks using familiar faces and unknown faces. Each subject was accompanied by 4 familiar people (parents, siblings or friends), which were photographed by expressing the 6 Ekman's basic emotions. Face emotion recognition in familiar faces was assessed with this ad hoc instrument. In each case, the patient scored (from 1 to 10) the subjective familiarity and affective valence corresponding to each person.

RESULTS

Patients with schizophrenia not only showed a deficit in the recognition of emotions on unknown faces (p=.01), but they also showed an even more pronounced deficit on familiar faces (p=.001). Controls had a similar success rate in the unknown faces task (mean: 18 +/- 2.2) and the familiar face task (mean: 17.4 +/- 3). However, patients had a significantly lower score in the familiar faces task (mean: 13.2 +/- 3.8) than in the unknown faces task (mean: 16 +/- 2.4; p<.05). In both tests, the highest number of errors was with emotions of anger and fear. Subjectively, the patient group showed a lower level of familiarity and emotional valence to their respective relatives (p<.01).

CONCLUSIONS

The sense of familiarity may be a factor involved in the face emotion recognition and it may be disturbed in schizophrenia.

The efficacy of systemic therapy for internalizing and other disorders of childhood and adolescence: a systematic review of 38 randomized trials

Systemic therapy (ST) is one of the most widely applied psychotherapeutic approaches in the treatment of children and adolescents, yet few systematic reviews exist on the efficacy of ST with this age group. Parallel to a similar study on adults, a systematic review was performed to analyze the efficacy of ST in the treatment of children and adolescents. All randomized or matched controlled trials (RCT) evaluating ST in any setting with child and adolescent index patients were identified by database searches and cross-references, as well as in existing meta-analyses and reviews. Inclusion criteria were: index patient diagnosed with a DSM-IV or ICD-10 listed psychological disorder, or suffering from other clinically relevant conditions, and trial published by December 2011. Studies were analyzed according to their sample, research methodology, interventions applied, and results at end-of-treatment and at follow-up. This article presents findings for internalizing and mixed disorders. Thirty-eight trials were identified, with 33 showing ST to be efficacious for the treatment of internalizing disorders (including mood disorders, eating disorders, and psychological factors in somatic illness). There is some evidence for ST being also efficacious in mixed disorders, anxiety disorders, Asperger disorder, and in cases of child neglect. Results were stable across follow-up periods of up to 5 years. Trials on the efficacy of ST for externalizing disorders are presented in a second article. There is a sound evidence base for the efficacy of ST as a treatment for internalizing disorders of child and adolescent patients.

A randomized controlled trial of bibliotherapy for carers of young people with first-episode psychosis

Caring for young people with first-episode psychosis (FEP) is challenging and can adversely affect carer well-being, with limited evidence-based support materials available. We aimed to examine whether completion of a self-directed problem-solving bibliotherapy among carers of young people with FEP led to a better experience of caring, less distress and expressed emotion, and better general health than carers who only received treatment as usual (TAU). A randomized controlled trial was conducted across two early-intervention psychosis services in Melbourne, Australia. A total of 124 carers were randomized to problem-solving bibliotherapy intervention (PSBI) or TAU and assessed at baseline, 6-week and 16-week follow-up. Intent-to-treat analyses were carried out and indicated that recipients of PSBI had a more favorable experience of caring than those receiving TAU, and these effects were sustained at both follow-up time points. Across the other measures, both groups demonstrated improvements by week 16, although the PBSI group tended to improve earlier. The PSBI group experienced a greater reduction in negative emotional evaluations of the need to provide additional support to young people with FEP than the TAU group by week 6, while the level of psychological distress decreased at a greater rate from baseline to 6 weeks in the PSBI compared with the TAU group. These findings support the use of problem-solving bibliotherapy for first-time carers, particularly as a cost-effective adjunct to TAU.

The development of a family intervention competency assessment and reflection scale (FICARS) for psychosis

Family intervention (FI) for psychosis has a robust evidence base. In recommending its use the revised NICE schizophrenia guideline states 'Healthcare professionals providing psychological interventions should have an appropriate level of competence'. Yet, no definitive instrument exists to outline what competences are required during and post FI training or help recruit staff with the appropriate knowledge and skill. This paper reports on the development of a Family Intervention competency assessment and reflection scale (FICARS). Using a systematic three-staged approach commonly used in health outcomes measurement development, a comprehensive literature review on UK-based FI training and commonly used assessment tools was undertaken. A FICARS draft was then constructed and revised in consultation with expert FI clinicians. Finally, a content validity study with FI trainers and students across three FI training programmes was undertaken to optimize FICARS aim to promote reflective assessment and professional development in FI skills and practice.

Informal caregivers in early psychosis: evaluation of need for psychosocial intervention and unresolved grief

AIM

Relatives of service users involved with Early Intervention in Psychosis services often experience substantial distress and need associated with their role as caregivers. This study adapted versions of the relatives cardinal needs schedule and the Texas inventory of grief and tested their utility for use among relatives of service users experiencing a first episode of psychosis.

METHODS

staff, service users and relatives were consulted and a pilot took place which facilitated the creation of the relatives' urgent needs schedule-early Intervention version (RUNS-EI) and the Texas inventory of grief-early Intervention version (TIG-EI). Thirty service user-caregiver dyads were recruited for the evaluation of reliability and validity.

RESULTS

The level of 'urgent need' identified by the RUNS-EI demonstrated good concurrent validity with measures of service user social and global functioning as well as measures assessing relatives' distress, expressed emotion and grief. The measure demonstrated acceptable interrater and test-retest reliability. The profile of need is reported. The TIG-EI demonstrated 'excellent' internal consistency. It also demonstrated good concurrent validity with increased TIG-EI scores correlated with reduced service user social and global functioning as well as increased scores on measures assessing relatives' distress, expressed emotion and caregiving needs.

CONCLUSIONS

Results appear to support these assessments' utility as measures of need for psychosocial intervention and grief among relatives supporting service users experiencing a first episode of psychosis.

Nidotherapy for people with schizophrenia

BACKGROUND

Nidotherapy is a therapeutic method that principally aims to modify the environment of people with schizophrenia and other serious mental illnesses, whilst working in conjunction with, or alongside other treatments. Rather than focusing on direct treatments or interventions, the aim is to help the individual identify the need for, and work to effect environmental change with the aim of minimising the impact of any form of mental disorder on the individual and society.

OBJECTIVES

To review the effects of nidotherapy added to standard care, compared with standard care or no treatment for people with schizophrenia or related disorders.

SEARCH METHODS

We searched the Cochrane Schizophrenia Group Trials Register (December 2011) and supplemented this by contacting relevant study authors, handsearching nidotherapy articles and manually searching reference lists.

SELECTION CRITERIA

All randomised controlled trials (RCTs) that compared nidotherapy with standard care or no treatment.

DATA COLLECTION AND ANALYSIS

We independently selected and quality assessed potential trials. We reliably extracted data. We calculated risk ratios (RR) and 95% confidence intervals (CI) of homogeneous dichotomous data. Scale data were only extracted from valid scales. For non-skewed continuous endpoint data, we estimated mean difference (MD) between groups. Skewed data have been presented in the Data and analyses as 'other data', with acknowledged means and standard deviations. We assessed risk of bias for the included study and used GRADE to create a 'Summary of findings' table.

MAIN RESULTS

We included only one study that compared nidotherapy-enhanced standard care with standard care alone (total 52 participants); this study was classified by its authors as a 'pilot study'. The duration of the included study was 18 months in total. The single study examined the short-term (up to six months) and medium-term (between six and 12 months) effects of nidotherapy-enhanced standard care versus standard care.Nidotherapy-enhanced standard care was favoured over standard care for social functioning in both the short term (n = 50, 1 RCT, MD -2.10, 95% CI -4.66 to 0.46) and medium term (n = 37, 1 RCT, MD -1.70, 95% CI -4.60 to 1.20, Very low quality); however, these results did not reach statistical significance. Results concerning engagement with non-inpatient services favoured the intervention group in both the short term (n = 50, 1 RCT, MD 2.00, 95% CI 0.13 to 3.87) and medium term (n = 37, 1 RCT, MD 1.70, 95% CI -0.09 to 3.49), with statistical significance evident in the short term, but not in the medium term. Results of people leaving the study early favoured the intervention in the short term (n = 52, 1 RCT, RR 0.86, 95% CI 0.06 to 12.98), with slight favour of the control group at medium term (n = 50, 1 RCT, RR 0.99, 95% CI 0.39 to 2.54); again, these results did not reach statistical significance. Results for the adverse effects/events of death (measured by 12 months) favoured the intervention (n = 52, 1 RCT, RR 0.29, 95% CI 0.01 to 6.74, Very low quality) but with no statistical significance. Skewed results were available for mental state, service use, and economic outcomes, and present a mixed picture of the benefits of nidotherapy.

AUTHORS' CONCLUSIONS

Further research is needed into the possible benefits or harms of this newly-formulated therapy. Until such research is available, patients, clinicians, managers and policymakers should consider it an experimental approach.

Burden of informal care giving to patients with psychoses: a descriptive and methodological study

BACKGROUND

There is a lack of studies of the size of burden associated with informal care giving in psychosis.

AIMS

To evaluate the objective and subjective burden of informal care giving to patients with psychoses, and to compare a diary and recall method for assessments of objective burden.

METHOD

Patients and their informal caregivers were recruited from nine Swedish psychiatric outpatient centres. Subjective burden was assessed at inclusion using the CarerQoL and COPE index scales. The objective burden (time and money spent) was assessed by the caregivers daily using diaries over four weeks and by recall at the end of weeks 1 and 2.

RESULTS

One-hundred and seven patients (53% females; mean age 43 ± 11) and 118 informal caregivers (67%; 58 ± 15 years) were recruited. Informal caregivers spent 22.5 hours/week and about 14% of their gross income on care-related activities. The time spent was underestimated by two to 20 hours when assessed by recall than by daily diary records. The most prominent aspects of the subjective burden were mental problems.

CONCLUSION

Despite a substantial amount of time and money spent on care giving, the informal caregivers perceived the mental aspects of burden as the most troublesome. The informal caregiver burden is considerable and should be taken into account when evaluating effects of health care provided to patients with psychoses.

Aripiprazole versus other atypical antipsychotics for schizophrenia

BACKGROUND

In most western industrialised countries, second generation (atypical) antipsychotics are recommended as first line drug treatments for people with schizophrenia. In this review we specifically examine how the efficacy and tolerability of one such agent - aripiprazole - differs from that of other comparable second generation antipsychotics.

OBJECTIVES

To evaluate the effects of aripiprazole compared with other atypical antipsychotics for people with schizophrenia and schizophrenia-like psychoses.

SEARCH METHODS

We searched the Cochrane Schizophrenia Group Trials Register (November 2011), inspected references of all identified studies for further trials, and contacted relevant pharmaceutical companies, drug approval agencies and authors of trials for additional information.

SELECTION CRITERIA

We included all randomised clinical trials (RCTs) comparing aripiprazole (oral) with oral and parenteral forms of amisulpride, clozapine, olanzapine, quetiapine, risperidone, sertindole, ziprasidone or zotepine for people with schizophrenia or schizophrenia-like psychoses.

DATA COLLECTION AND ANALYSIS

We extracted data independently. For dichotomous data we calculated risk ratios (RR) and their 95% confidence intervals (CI) on an intention-to-treat basis based on a random-effects model. Where possible, we calculated illustrative comparative risks for primary outcomes. For continuous data, we calculated mean differences (MD), again based on a random-effects model. We assessed risk of bias for each included study.

MAIN RESULTS

We included 12 trials involving 6389 patients. Aripiprazole was compared to olanzapine, risperidone and ziprasidone. All trials were sponsored by an interested drug manufacturer. The overall number of participants leaving studies early was 30% to 40%, limiting validity (no differences between groups).When compared with olanzapine no differences were apparent for global state (no clinically important change: n = 703, 1 RCT, RR short-term 1.00 95% CI 0.81 to 1.22; n = 317, 1 RCT, RR medium-term 1.08 95% CI 0.95 to 1.22) but mental state tended to favour olanzapine (n = 1360, 3 RCTs, MD total Positive and Negative Syndrome Scale (PANSS) 4.68 95% CI 2.21 to 7.16). There was no significant difference in extrapyramidal symptoms (n = 529, 2 RCTs, RR 0.99 95% CI 0.62 to 1.59) but fewer in the aripiprazole group had increased cholesterol levels (n = 223, 1 RCT, RR 0.32 95% CI 0.19 to 0.54) or weight gain of 7% or more of total body weight (n = 1095, 3 RCTs, RR 0.39 95% CI 0.28 to 0.54).When compared with risperidone, aripiprazole showed no advantage in terms of global state (n = 384, 2 RCTs, RR no important improvement 1.14 95% CI 0.81 to 1.60) or mental state (n = 372, 2 RCTs, MD total PANSS 1.50 95% CI -2.96 to 5.96).One study compared aripiprazole with ziprasidone (n = 247) and both the groups reported similar change in the global state (n = 247, 1 RCT, MD average change in Clinical Global Impression-Severity (CGI-S) score -0.03 95% CI -0.28 to 0.22) and mental state (n = 247, 1 RCT, MD change PANSS -3.00 95% CI -7.29 to 1.29).When compared with any one of several new generation antipsychotic drugs the aripiprazole group showed improvement in global state in energy (n = 523, 1 RCT, RR 0.69 95% CI 0.56 to 0.84), mood (n = 523, 1 RCT, RR 0.77 95% CI 0.65 to 0.92), negative symptoms (n = 523, 1 RCT, RR 0.82 95% CI 0.68 to 0.99), somnolence (n = 523, 1 RCT, RR 0.80 95% CI 0.69 to 0.93) and weight gain (n = 523, 1 RCT, RR 0.84 95% CI 0.76 to 0.94). Significantly more people given aripiprazole reported symptoms of nausea (n = 2881, 3 RCTs, RR 3.13 95% CI 2.12 to 4.61) but weight gain (7% or more of total body weight) was less common in people allocated aripiprazole (n = 330, 1 RCT, RR 0.35 95% CI 0.19 to 0.64). Aripiprazole may have value in aggression but data are limited. This will be the focus of another review.

AUTHORS' CONCLUSIONS

Information on all comparisons are of limited quality, are incomplete and problematic to apply clinically. Aripiprazole is an antipsychotic drug with a variant but not absent adverse effect profile. Long-term data are sparse and there is considerable scope for another update of this review as new data emerges from the many Chinese studies as well as from ongoing larger, independent pragmatic trials.

Internet-based interventions for psychosis: a sneak-peek into the future

The Internet and mobile technologies are becoming ubiquitous. However, the potential of these technologies to support people with psychosis has been unexplored and the development of innovative e-based interventions is overdue. Research suggests the acceptability and effectiveness of such interventions in psychosis. Internet-based technologies have the potential to transform psychosis treatment by enhancing the accessibility of evidence-based interventions, fostering engagement with mental health services, and maintaining treatment benefits over the long term. This article reviews the current evidence on Internet-based interventions for psychosis, including potential benefits, risks, and future challenges. Recommendations are proposed for developing future online interventions for psychosis.

Cost-effectiveness of family psychoeducation to prevent relapse in major depression: results from a randomized controlled trial

BACKGROUND

Family psychoeducation is a relatively simple and straightforward intervention whose prophylactic effectiveness and cost-effectiveness is well-established for schizophrenia. We have recently demonstrated its effectiveness for unipolar depression, but its cost-effectiveness has never been examined. We hereby report a cost-effectiveness analysis alongside a randomized controlled trial in order to assess its cost-effectiveness for preventing relapse/recurrence in depression.

METHODS

Fifty-seven patients diagnosed with major depression and undergoing its maintenance treatment, and their primary family members were randomized to treatment as usual (TAU) only or to TAU plus family psychoeducation, which consisted of four 2-hour multiple-family sessions consisting of didactic lectures about depression (30 minutes) and group discussion and problem solving (60-90 minutes). The economic analyses were undertaken from the perspective of the National Health Insurance (NHI), assuming the most reasonable price of US$50 per psychoeducation session per patient. The main outcome measures included relapse-free days and direct costs to the NHI.

RESULTS

The intervention group enjoyed 272 (SD: 7.1) relapse-free days, while the control group spent 214 (SD: 90.8) relapse-free days (Cox proportional hazard ratio=0.17, 95%CI: 0.04 to 0.75, p=0.002). Cost-effectiveness acceptability curves suggested that the family psychoeducation has 90% or more chances of being cost-effective if the decision-maker is prepared to pay US$20 for one additional relapse-free day. This cost-effectiveness finding was robust when the price for family psychoeducation ranged between 50% to 150% of the baseline scenario in sensitivity analyses. If a relapse-free day is considered to be worth $30 or more, all the pricing scenarios have a close to 100% probability of being cost-effective.

CONCLUSION

Family psychoeducation is effective in the relapse prevention of depression and is highly likely to be cost-effective if a relapse-free day is valued as US$20 or more.

Attitudes of relatives and staff towards family intervention in forensic services using Q methodology

Attitudes about family interventions have been identified as a possible reason for the poor implementation of such treatments. The current study used Q methodology to investigate the attitudes of relatives of forensic service users and clinical staff towards family interventions in medium secure forensic units, particularly when facilitated by a web camera. Eighteen relatives and twenty-nine staff completed a sixty-one item Q sort to obtain their idiosyncratic views about family intervention. The results indicated that relatives and staff mostly held positive attitudes towards family intervention. Relatives showed some uncertainty towards family intervention that may reflect the lack of involvement they receive from the forensic service. Staff highlighted key barriers to successful implementation such as lack of dedicated staff time for family work and few staff adequately trained in family intervention. Despite agreement with the web-based forensic family intervention technique and its benefits, both staff and relatives predicted problems in the technique.

Stigmatizing attitudes in relatives of people with schizophrenia: a study using the Attribution Questionnaire AQ-27

BACKGROUND: Family members of people with mental disorders can contribute to stigmatization. Because of the lack of adequate information and resources, and the fatigue resulting from daily care, the family can reinforce social exclusion of the mentally ill and disbelieve recovery. Furthermore, family members may also suffer from self-stigma, experiencing a decrease in their own self-esteem and self-worth. OBJECTIVE: To evaluate the presence of stigmatizing attitudes towards patients diagnosed with schizophrenia in a group of relatives of patients with this disorder. METHODS: In this exploratory study, we surveyed 40 family members of patients with schizophrenia seen at the Community Psychiatry Unit of the Psychiatry Department at Centro Hospitalar de São João (CHSJ), in Porto, Portugal, using a preliminary version of the Attribution Questionnaire AQ-27 in Portuguese. RESULTS: The questionnaire dimensions with the highest mean scores were help, pity, and coercion, followed by segregation, anger, avoidance, dangerousness, responsibility, and fear. These results suggest that relatives do not see people with schizophrenia as responsible for their illness and that they show concern and willingness to help. They avoid but do not fear people with schizophrenia and neither consider them dangerous. CONCLUSION: The participants expressed positive, little stigmatizing attitudes towards people with schizophrenia, probably as a result of their familiarity with severe mental disorder, an adequate attribution process, and low levels of perceived dangerousness. However, the high scores of coercion, pity, and segregation may reflect concealed stigmas that may influence the self-determination of the mentally ill, suggesting the need for psychoeducational interventions aimed at family members.

Family interventions in schizophrenia: Issues of relevance for Asian countries

A growing body of research evidence has confirmed the efficacy of family-interventions as adjuncts to antipsychotics for the treatment of schizophrenia. Much of the recent evidence for such interventions derives from Asian, principally Chinese, studies. These trials have shown that relatively simple forms of family-interventions have wide ranging benefits, and can be implemented successfully in routine clinical settings. With the accumulation of this evidence in their favour, family-interventions for schizophrenia in Asia are poised to take the next critical step, that of wider implementation and improved accessibility for potential users. However, several issues merit consideration. Family-interventions need to be based on a culturally-informed theory, which incorporates cultural variables of relevance in these countries. While the ideal format for conducting family-interventions is still to be determined, it is quite evident that for such interventions to be useful they need to be simple, inexpensive, needs-based, and tailored to suit the socio-cultural realities of mental health systems in Asian countries. The evidence also suggests that delivery by non-specialist personnel is the best way to ensure that such services reach those who stand to benefit most from these treatments. However, there are several existing challenges to the process of dissemination of family-interventions. The major challenges include the achievement of a critical mass of trained professionals capable of delivering these interventions, and finding innovative solutions to make family-interventions more acceptable to families. If these hurdles are overcome, we could look forward to a genuine collaboration with families, who have always been the mainstay of care for the mentally ill in Asia.

The effect of a brief family intervention on primary carer's functioning and their schizophrenic relatives levels of psychopathology in India

This study examined the short term effects of a brief familial intervention on schizophrenic the patient's levels of psychopathology and their primary caregiver's functioning in India. Caregiver functioning was measured by the caregiver's levels of burden and coping along with the patient's perceived level of expressed emotion (EE). The participants were 18 schizophrenic patients and their related primary carer from a medical facility in India. The patients' levels of psychopathology and EE were assessed at baseline and at completion of the study with the Positive and Negative Syndrome Scale (PANSS; Kay et al., 1987) and the Family Emotional Involvement And Criticism Scale (FEICS; Shields et al., 1992), respectively. The primary caregiver's levels of burden and coping were also measured at baseline and upon completion of the study by the Burden Assessment Scale (BAS; Thara et al., 1998) and the Family Crisis Oriented Personal Evaluation Scale (F-COPES; McCubbin et al., 1981), respectively. The brief intervention was comprised of 3 one hour sessions aimed at educating the primary caregiver and patient about schizophrenia; along with improving their communication, problem solving skills and expression of emotions. A significant improvement was found between baseline and the final 3-month follow-up on measures of psychopathology for the patients, as well as family functioning for both the caregivers and patients. The implications of the findings are discussed, along with future research directions.

Comprehensive early intervention for patients with first-episode psychosis in Japan (J-CAP): study protocol for a randomised controlled trial

Introduction

Comprehensive approaches for patients with psychotic symptoms play essential roles in the symptomatic and functional outcomes of patients, especially during disease onset. In Japan, the shortage of mental health services, particularly for outpatients, and community-based supports has been a major problem. The purpose of this trial is to investigate the effectiveness and affordability of 18-month comprehensive early intervention services for patients with first-episode psychosis compared with typical treatment.

Methods

This interventional, parallel, single-blinded (open but blinded raters trial) was effectively designed. The participants are patients with a diagnosis of F2 or F3 (International Classification of Disease, 10 th revision), with psychotic symptoms. The inclusion criteria were an age of 15-35 years, onset of psychotic symptoms within 5 years, first-episode psychosis, and residence in the catchment area of each site. Allocation will be conducted equally between case management and standard care groups. After enrollment, standard care will be provided for both groups, and community-based care to promote recovery for 18 months will be provided for the comprehensive approach group. The primary outcome will be the function domain of the global assessment of functioning scores at 18 months after enrollment. Data assessment will be performed at enrollment and 18, 36, and 60 months after enrollment. The target sample size will be 150, and registration will occur from March 1, 2011, to September 30, 2012.

Discussion

This trial will provide promising results about the effectiveness and cost-effectiveness of early intervention services in Japan to improve the quality and quantity of community mental health services.

Family interventions in early psychosis: specificity and effectiveness

The first episode of psychosis frequently occurs during adolescence and early adulthood, and is associated with high levels of trauma, affective disturbance and suicide. The social networks of service users often decrease significantly following the first onset, although many will remain in close contact with some family members particularly during the early phases. However, the negative impact of psychosis on families and their relationship with the identified service user are well documented. Family intervention is a recommended and evidence-based treatment in later psychosis. In this paper, we review the literature on family interventions in early psychosis in the context of new evidence for its efficacy and its routine incorporation in early intervention services for psychosis.
