Art therapy as an adjuvant treatment for schizophrenia: A protocol for an updated systematic review and subgroup meta-analysis of randomized clinical trials following the PRISMA guidelines

BACKGROUND

The efficacy of art therapy as an adjuvant treatment for schizophrenia remains inconclusive, and variation in the effects of art therapy on schizophrenia by the type of schizophrenia, severity of schizophrenia, type of art therapy, follow-up duration, or different populations has never been systematically assessed. The objective of this study is to systematically evaluate the effects of art therapy on schizophrenia and to determine whether there are some potential influencing factors affecting the effects of art therapy.

METHODS

Seven online databases will be searched from their inception until June 30, 2022. All the relevant randomized clinical trials (RCTs) comparing art therapy plus standardized treatment versus standardized treatment alone for schizophrenia will be selected and assessed for inclusion. The Cochrane risk-of-bias tool will be used to evaluate the methodological quality of the included RCTs. Review Manager 5.4 will be used to analyze all the data obtained. Mental health symptoms are defined as the primary outcome, and the secondary outcomes include the Global Assessment of Functioning score, quality of life, functional remission, and the level of self-esteem. Subgroup analyses will be performed based on the type of schizophrenia, severity of schizophrenia, type of art therapy, follow-up duration, or different populations.

RESULTS

The results will be published in a peer-reviewed journal.

CONCLUSIONS

This updated systematic review and subgroup meta-analysis will evaluate the effects of art therapy as adjunctive treatment to standardized treatment in patients with schizophrenia and determine whether there are some potential confounding variables affecting the effects of art therapy on the outcomes of schizophrenia patients, thus strengthening the evidence base for the clinical application of this combination therapy for schizophrenia.

A systematic review of social functioning outcome measures in schizophrenia with a focus on suitability for intervention research

Social functioning is an important part of recovery and a key treatment target in clinical research in schizophrenia. Evaluating and comparing interventions is challenged by the choice of many measures which focus on different aspects of functioning, with little to guide selection. This results in difficulties comparing outcomes of treatment where studies have used different measures. To improve the measurement of social functioning in intervention research, we aimed to provide practical information on suitability of measures. We conducted a systematic review of measures developed or psychometrically evaluated since 2007, and assessed and discussed the structure, content, quality, and the use of the measures in intervention research. Thirty-two measures of social functioning and 22 validation papers were identified. Measures included structured questionnaires, semi-structured interviews, and assessment of performance on specific tasks. The content of measures was organised into eight categories, which are in order of frequency with which they were covered by measures: activities of daily living, productive activity, relationships, leisure activities, cognition, anti-social behaviour, psychosis symptoms and self-esteem and empowerment. In terms of quality, most measures were rated as moderate, with the Personal and Social Performance Scale gaining the highest rating. However, there was little data on responsiveness of measures, or how they compare to objective or 'real-world' indicators of functioning. The Social Functioning Scale and Personal and Social Performance Scale have been most frequently used in intervention studies to date. Future research should aim to provide further data on psychometric properties relevant to intervention research.
