Cognitive behavioural therapy (brief versus standard duration) for schizophrenia

Area of Science:

• Psychiatry
• Psychotherapy
• Clinical Psychology

Background:

• Cognitive behavioural therapy for psychosis (CBTp) is a recognized treatment for schizophrenia.
• Limitations in resources and training hinder widespread CBTp provision.
• Brief CBTp is proposed as a potential solution to improve accessibility.

Purpose of the Study:

• To review the effects of brief CBTp (6-10 sessions) compared to standard CBTp (12-20 sessions) for schizophrenia.
• To assess the comparative efficacy and outcomes of abbreviated versus full-duration CBTp protocols.

Main Methods:

• Systematic search of multiple databases including Cochrane Schizophrenia Group's Trials Register.
• Inclusion criteria focused on randomized controlled trials comparing brief CBTp with standard CBTp in adults with schizophrenia.
• Study selection and data extraction performed independently by two reviewers.

Main Results:

• Seven studies utilizing brief CBTp were identified.
• Crucially, no studies directly compared brief CBTp with standard CBTp in terms of duration or outcomes.
• Consequently, no studies met the inclusion criteria for direct comparison.

Conclusions:

• There is a significant lack of scientific literature comparing brief CBTp to standard CBTp for schizophrenia.
• The comparative effectiveness of brief CBTp versus standard CBTp cannot be determined.
• Well-designed randomized trials are urgently needed to address this evidence gap in research and clinical practice.
