Cost-benefit analyses of employment services for individuals with intellectual and developmental disabilities: A scoping review

Abstract

BACKGROUND: Understanding the cost-benefit of vocational rehabilitation services is critical to improve competitive integrated employment outcomes for individuals with intellectual and developmental disabilities (IDD). OBJECTIVE: The purpose of this scoping review was to analyze and synthesize micro and macroeconomic analyses of various types of vocational services which promote the employment outcomes of individuals with IDD. METHODS: This scoping review searched peer-reviewed and grey literature sources published between 2000 and 2020, examining both micro and macroeconomic analyses. RESULTS: A total of 26 studies met inclusion criteria. The majority of studies reported positive effects for the cost-benefit of integrated service approaches such as supported and customized employment. Conversely, our findings show no cost-benefit for sheltered workshops, and in some cases, negative effects. CONCLUSION: Limitations to the included studies as well as implications and recommendations for practice, policy, and future research are discussed.
