The importance of employment in society is unmistakable, but for many people sustained employment remains elusive. The unemployment rate for individuals with disabilities is staggering, and the consequences of being unemployed affects those individuals, their families, and society. The effects of performance feedback delivered via covert audio coaching on the job performance of supported employees were examined in this investigation. A multiple baseline design across employees and work tasks was used to evaluate the effects of the intervention on work performance. Supported employees made substantial improvements on their work performance, and the improvements maintained for 4 to 5 weeks following the removal of the intervention. The results have implications for the use of covert audio coaching in employment and other settings.
Video-based instruction (VBI) has a substantial amount of research supporting its use with individuals with autism spectrum disorder and other developmental disabilities. However, it has typically been implemented as a treatment package containing multiple interventions. Additionally, there are procedural variations of VBI. Thus, it is difficult to determine which components and characteristics/parameters of VBI are more or less responsible for behavior change. Researchers have conducted comparative studies using single-subject design research to understand the relative effectiveness of the components and parameters routinely used as part of VBI treatment packages. The purpose of this article was to systematically review the literature on VBI comparative studies whereby component and parametric analyses were conducted. Twenty-four studies met our inclusion criteria. The features and results of these studies are summarized, and implications for future research and practice are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
