A Randomized Controlled Trial of a Correspondence-Based Intervention for Carers of Relatives with Psychosis

Effectiveness of family interventions for patients with schizophrenia: A systematic review and meta-analysis

The family is the primary caregiver for most patients with schizophrenia, and their roles are essential in patients' illness trajectories and outcomes. Due to this, various family interventions for schizophrenia have been developed and applied to the relatives who take care of their family members with schizophrenia. This study examined the effectiveness of existing family interventions for schizophrenia in achieving their target outcomes at both the family and patient levels by utilizing a systematic review and meta-analysis. Combinations of terms were used to search for relevant studies from the databases. Thirty-seven randomized controlled trials that met the inclusion criteria were included in the analysis. Based on the pooled result of the included studies, the programmes significantly improved the targeted outcomes with large effect size. The programmes' impacts on family-related outcomes were higher than those on patients. Among the targeted outcomes, patients' treatment satisfaction and adherence and family caregivers' mental health were the most remarkable outcomes that had improved from the included programmes. Conversely, outcomes related to family relationships, caregiving experiences, perceived social support of family caregivers, and patients' medication use did not see significant improvements. The programmes delivered to individual family units and only to the family caregivers were more effective than those delivered to groups of caregivers and caregivers and patients together, respectively. Programme-focused interventions were more effective than emotion-focused ones. Based on these findings, an in-home visiting nurse programme or advanced technology is suggested when applying family interventions for schizophrenia in practice.

Psychosocial interventions for carers of people with severe mental and substance use disorders: a systematic review and meta-analysis

BACKGROUND

Severe mental disorders - such as schizophrenia, bipolar disorder, and substance use disorders - exert a negative impact not only on affected people but also on their carers. To support carers of people with severe mental disorders, several psychosocial interventions have been developed.

METHODS

This systematic review and meta-analysis aimed to assess whether psychosocial interventions for carers of persons with schizophrenia, bipolar disorder, or substance use disorders produce benefit/harm with respect to a series of outcomes - including subjective and objective burden, depressive symptoms, well-being/quality of life, sleep, skills/knowledge, self-efficacy, physical health - as compared to standard support/support as usual or other control conditions.

RESULTS

In carers of persons with schizophrenia, psychoeducational interventions were associated with significant improvement in personal burden, well-being, and knowledge about the illness; and a supportive-educational intervention with an improvement in personal burden. In carers of persons with bipolar disorder, psychoeducational interventions were associated with significant improvement in personal burden and depressive symptoms; family-led supportive interventions with an improvement in family burden; family-focused intervention and online "mi.spot" intervention with a significant reduction in depressive symptoms. Psychosocial interventions used for carers of persons with substance use disorders were found to be overall effective on the level of well-being, but the low number of trials did not allow detection of differences between the various psychosocial interventions.

CONCLUSIONS

The quality of the evidence ranged from very low to moderate, suggesting the need for further better-quality research.

Self-Report Measures Assessing Aspects of Personal Recovery in Relatives and Other Informal Carers of Those With Psychosis: A Systematic Review

Background

Providing long-term care for a family member with psychosis can cause significant distress for informal carers due to the trauma of seeing their loved one in crisis, dealing with the difficult symptoms of psychosis and the burden of providing care. An important aspect of carers' adjustment can be construed as their personal recovery in relation to having a relative affected by psychosis. Self-report measures are increasingly used to assess personal recovery in service users, but less is known about the utility of such tools for carers.

Aims

This review aimed to identify all self-report measures assessing aspects of carers' personal recovery, and to quality appraise them.

Methods

Academic Search Ultimate, CINAHL, MEDLINE, PsychINFO and PubMed were searched for articles that reported the development of self-report measures created for carers of those with psychosis. Studies were appraised using the Consensus-based Standards for the Selection of health status Measurement INstruments (COSMIN) checklist. A Levels of Evidence synthesis provided overall quality scores for each measure.

Results

The search identified 3,154 articles for initial screening. From a total of 322 full text articles, 95 self-report measures were identified with a final 10 measures included for the quality assessment showing varying levels of psychometric rigor.

Conclusions

The results show that no single self-report measure is currently available for use to comprehensively assess personal recovery for carers, highlighting the need for further research in this area and the development of a new measure.

A systematic review and meta-analysis of psychological interventions to improve mental wellbeing

Our current understanding of the efficacy of psychological interventions in improving mental states of wellbeing is incomplete. This study aimed to overcome limitations of previous reviews by examining the efficacy of distinct types of psychological interventions, irrespective of their theoretical underpinning, and the impact of various moderators, in a unified systematic review and meta-analysis. Four-hundred-and-nineteen randomized controlled trials from clinical and non-clinical populations (n = 53,288) were identified for inclusion. Mindfulness-based and multi-component positive psychological interventions demonstrated the greatest efficacy in both clinical and non-clinical populations. Meta-analyses also found that singular positive psychological interventions, cognitive and behavioural therapy-based, acceptance and commitment therapy-based, and reminiscence interventions were impactful. Effect sizes were moderate at best, but differed according to target population and moderator, most notably intervention intensity. The evidence quality was generally low to moderate. While the evidence requires further advancement, the review provides insight into how psychological interventions can be designed to improve mental wellbeing.

Caring for caregivers: Understanding and meeting their needs in coping with first episode psychosis

AIM

The first episode of psychosis is a challenging time for both patients and those who care for them. Although literature on treatment is plentiful, literature on how to best support caregivers is more scarce. This review was undertaken to better understand the caregiver experience, determine which interventions most effectively alleviate their burden and examine which other factors may affect outcomes.

METHODS

Articles were retrieved from PubMed and OVID using the following search terms: first episode psychosis (FEP), schizophrenia, caregiver, intervention and burden in various combinations. Only peer-reviewed articles germane to FEP caregiver experience and interventions written in English were included.

RESULTS

Caregivers can experience grief, guilt and anxiety during this time. While concerned for their loved one, their own lives take a back seat and their mental and physical health are adversely affected. Some are better prepared to cope and are typically warm, decisive, confident and optimistic. Their families are organized and flexible. Others are less prepared and are more likely to have poor self-esteem, use avoidant coping strategies and be overly critical. Their families are controlling and have difficulty with communication and balance. These caregivers stand to benefit most from interventions.

CONCLUSIONS

Effective interventions incorporate psychoeducation, problem solving strategies, peer support and clinician guidance. A higher level of interaction with facilitators and peers is associated with better results. Benefits include decreases in caregiver burden, depressive and anxious symptoms and feelings of shame and isolation. Although the literature has yet to isolate the key factors of a successful intervention, this review provides practical suggestions for clinicians and further illustrates the need for more research.

Social problem solving in carers of young people with a first episode of psychosis: a randomized controlled trial

AIM

Caring for young people with first-episode psychosis is difficult and demanding, and has detrimental effects on carers' well-being, with few evidence-based resources available to assist carers to deal with the problems they are confronted with in this situation. We aimed to examine if completion of a self-directed problem-solving bibliotherapy by first-time carers of young people with first-episode psychosis improved their social problem solving compared with carers who only received treatment as usual.

METHODS

A randomized controlled trial was carried out through two early intervention psychosis services in Melbourne, Australia. A sample of 124 carers were randomized to problem-solving bibliotherapy or treatment as usual. Participants were assessed at baseline, 6- and 16-week follow-up.

RESULTS

Intent-to-treat analyses were used and showed that recipients of bibliotherapy had greater social problem-solving abilities than those receiving treatment as usual, and these effects were maintained at both follow-up time points.

CONCLUSIONS

Our findings affirm that bibliotherapy, as a low-cost complement to treatment as usual for carers, had some effects in improving their problem-solving skills when addressing problems related to the care and support of young people with first-episode psychosis.
