Analysis of interventions to reduce stigma related to mental disorder: A critical systematic review

Objective: This review aimed to find and assess mental disorder stigma management solutions. Methods: The PROSPERO review ID is CRD42022369853 and followed the PRISMA protocol. This review recruited language-neutral publications from Scielo, Medline (via PubMed), and Google Scholar from 2019 to 2023. Three psychiatrists helped with selection, data collection and analysis, risk of bias assessment, and methodological quality rating. The ROBIS instrument assessed systematic review bias, while the Cochrane Handbook for Systematic Reviews of Interventions assessed CT bias. Use the Oxford Centre for Evidence-Based Medicine's 2011 Levels of Evidence to evaluate methodological quality. Following peer review. Results: Thirteen articles addressed stigma therapies for mental diseases like depression, anxiety, bipolar affective disorder, and schizophrenia. Audiovisual tools, theoretical and practical classes, and clinical case discussions reduced stigma, with evidence levels of 2–3. Studies found various drawbacks: a) some research did not focus on stigma reduction; b) data reporting was restricted. Conclusions: These findings show that stigma-reduction treatments must be continual and successful across varied intervention groups.
