Effectiveness of interventions for improving social inclusion outcomes for people with disabilities in low- and middle-income countries: A systematic review.

Background: People with disabilities-more than a billion people worldwide-are frequently excluded from social and political life, and often experience stigmatising attitudes and behaviours from people without disabilities. This stigma, coupled with inaccessible environments and systems and institutional barriers (e.g., lack of inclusive legislation), may result in discrimination against people with disabilities (and their families) to the degree that they are not able to enjoy their rights on an equal basis with others. Objectives: This review examines the effectiveness of interventions for improving social inclusion outcomes (acquisition of skills for social inclusion, broad-based social inclusion, and improved relationships) for people with disabilities in low- and middle-income countries (LMICs). Search Methods: We searched academic and online databases, carried out citation tracking of included studies, and contacted experts to ensure our search was as comprehensive as possible. We also ran the searches with search terms specific to social inclusion review using Open Alex in EPPI reviewer. Selection Criteria: We included all studies which reported on impact evaluations of interventions to improve social inclusion outcomes for people with disabilities in LMIC. Data Collection and Analysis: We used review management software EPPI Reviewer to screen the search results. Two review authors independently extracted the data from each study report, including for the confidence in study findings appraisal. Data and information were extracted regarding available characteristics of participants, intervention characteristics and control conditions, research design, sample size, risk of bias and outcomes, and results. Random-effects inverse variance weighted meta-analytic methods were used to synthesise standardised mean differences for the outcomes. Main Results: We identified 37 experimental and quasi-experimental studies. Studies were conducted in 16 countries, with the majority of the included studies ( Authors’ Conclusions: The review's findings suggest that various interventions to improve the social inclusion of people with disabilities have a significant positive effect. Interventions such as social and communication training and personal assistance led to significant improvement in the social behaviour and social skills of people with disabilities. Studies targeting broad-based social inclusion showed a large and significant positive effect. A moderate effect was reported from interventions designed to improve relationships between people with disabilities and their families and communities. However, the findings of this review must be interpreted cautiously, given the low confidence in study methods, severe heterogeneity and significant publication bias. The available evidence focused primarily on individual-level barriers such as interventions for improving social or communications skills of people with disabilities and not the systemic drivers of exclusions such as addressing societal barriers to inclusion, such as stigma reduction, and interventions to strengthen legislation, infrastructure, and institutions.
