Most disability research originates from high-income countries, masking important cultural variability in how disability is conceptualized. Through 199 interviews with people living in Sierra Leone, we investigated the following research questions: (1) what are the experiences of community members with people with disabilities?; (2) what employment options or other resources are available for people with disabilities?; and (3) how do community members perceive people with disabilities? We used a mixed-method approach to data analysis by quantitizing the qualitative responses to further examine whether participants’ responses differed by urbanicity, age, or level of education. The results of this study provide insight into how disability is understood in a low-income country and reveal important directions for future research.

Most disability research is conducted in high-income countries, despite much of the world’s population living in low- and middle-income countries. Given the flexible nature of qualitative research, studies using this methodology have the potential to provide important insights into how disability is perceived across the globe. The aim of the current study was to synthesize the results of disability research in Western Africa to elucidate prominent themes and identify methodological and participant characteristics. Secondary purposes were to evaluate the quality of included studies. A total of 223 studies were included in this meta-synthesis. Findings reveal a diversity of disability-related themes and a need to increase transparency in reporting qualitative research. Implications and suggestions for future research are discussed.

Although quality guidelines for single-case intervention research emphasize the importance of concurrent baselines in multiple-baseline and multiple-probe designs, nonconcurrent variations on these designs persist in the research literature. This study describes a systematic review of special education intervention studies ( k = 406) between 1988 and 2020 that report using nonconcurrent multiple-baseline or multiple-probe designs to test interventions for individuals with disabilities ages 21 years and younger. We coded and synthesized study characteristics pertaining to participants, settings, interventions, data reporting, and contextual factors. Findings indicate the prevalence of nonconcurrent designs for intervention studies in a variety of settings addressing social and communication needs of individuals with disabilities. We discuss implications for research and practice and offer suggestions for improving the validity of nonconcurrent designs.
