Objective : This is a systematic review and meta-analysis study to determine the effect of community-based interventions being given to people with mental disabilities. Method : The analysis was based on the results of global randomized controlled trials (RCTs), published from 2010 to December 2019, on community-based interventions given to people with mental disabilities. The literature was searched and selected from Pubmed, EMbase, Cochrane, and CINAHL, and the quality of the literature was determined using Cochrane’s Risk of Bias (RoB). Seventeen studies were found eligible for analysis based on the inclusion and exclusion criteria in this study. The meta-analysis was performed using the RevMan 5.4.1 software. Results : The study group was composed of 2,615 subjects. The meta-analysis showed that the effect size of the interventions to address psychological symptoms was 9.67, and of the interventions to improve quality of life, 5.70. Thus, the community-based interventions both effectively addressed the psychological symptoms and improved the quality of life of people with mental disabilities. Conclusion : This study showed that community-based interventions being given to people with mental disability both effectively address psychological symptoms and improve the quality of life of people with mental disability. This result supports the continuation of the community-based interventions being given to people with mental disability and validates the need for comprehensive community-based interventions for people with mental disability.
