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

Abstract

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 (n = 13) from South Asia and nine each from East Asia, the Pacific, the Middle East, and North Africa. Most studies targeted children with disabilities (n = 23), and 12 targeted adults with disabilities. Most focused on people with intellectual disabilities (n = 20) and psychosocial disabilities (n = 13). Regarding intervention content, most (n = 17) of the included programmes aimed to improve the social and communication skills of people with disabilities through social skills training programmes. Ten studies aimed at providing personal assistance and support and evaluated the effects of a parent training programme on the interactive skills of parents of children and their children with disabilities. We calculated effect sizes from experimental and quasi‐experimental studies for outcomes on skills for social inclusion, relationships of people with disabilities with family and community members, and broad‐based social inclusion among people with disabilities. A meta‐analysis of 16 studies indicates an overall positive...

Do children with disabilities have the same opportunities to play as children without disabilities? Evidence from the multiple indicator cluster surveys in 38 low and middle-income countries

“… 25 , 26 , 27 Moreover, there also needs to be a particular focus on LMICs as data is lacking. 28 , 29 , 30 , 31 The focus on LMICs is crucial as 80% of people with disabilities reside in these countries. The level of exclusion, such as from schools, is likely to be particularly high in these settings, where health systems are also weaker.…”

Association between depressive symptoms and sarcopenia among middle-aged and elderly individuals in China: the mediation effect of activities of daily living (ADL) disability

“…Furthermore, ADL disability can impact psychological factors like self-esteem and social skills, indirectly affecting muscle health. Overall, addressing ADL capacity holistically is crucial for preventing and treating sarcopenia, requiring targeted interventions to improve muscle health and quality of life [ 52 – 54 ].…”

Socio-Pedagogical Strategies in Occupational Therapy for Children with Autism and Learning Difficulties

“…Research has consistently shown that children with autism often face barriers to inclusion in educational, recreational, and social activities due to stigma, discrimination, and lack of understanding from their peers and community members. Occupational therapists can work collaboratively with schools, community organizations, and families to promote acceptance, create inclusive environments, and facilitate meaningful social interactions for children with autism, said by Saran (2023).…”
