A Scoping Review of Empirical Literature on People with Intellectual Disability in Nigeria

Abstract

Intellectual disability (ID) is an emerging field of research in Nigeria. This review seeks to identify what has been published in order to describe the evidence and to identify the major gaps in knowledge and practice. A systematic search of five databases and an African disability journal yielded 15 papers that reported on empirical studies related to people with ID in Nigeria. Fifteen studies across the databases and journal searched met the inclusion criteria. The participants included adults and children with ID and their families. Twelve of the papers employed quantitative methods, two were qualitative and one was a mixed methods study. There is a paucity of empirical research on people with ID in Nigeria, thus emphasising the need for more primary research about people with ID living in Nigeria. Nigeria is estimated to have the largest population of people with disabilities in Africa; however, this review found limited empirical work regarding their lives, prevalence and care. This limited evidence hinders the understanding of the challenges people with an intellectual disability face and potentially inhibit the creation of policy-oriented solutions to their plights in a globalised world.
