The ability to make choices fuels the development of one's sense of agency and personal control. Yet as individuals with disabilities age, choice opportunities often become more limited and restricted in nature. Previous research reports that staff practices directly influence choice-making opportunities for adults with disabilities (Cobigo, Lachapelle, & Morin, 2010). Given the link between consumer choice opportunities and staff behavior, there exists a need to evaluate research on staff training practices in providing choice-making opportunities within postsecondary disability service settings. The current study presents a systematic literature review of staff training interventions in choice. Nine studies met inclusion criteria for further analysis and discussion. Results tentatively demonstrate the potential effectiveness of staff trainings in choice on a variety of outcomes, but the quality of the research base limit broad implications and overall confidence in the findings. Based on the findings, the researcher conducted a single-subject multiple-baseline-across-participants study to investigate the effects of a multicomponent training in choice on staff provision of choices. Findings yielded a functional relationship between the multicomponent training and the increase in the frequency of staff choice offerings and the overall correct completion of a choice sequence. Additionally, results indicate a proportionate relationship between staff choice and consumer choice-making. The researcher discusses implications of results for future research.
