PROTOCOL: Effectiveness of adult employment assistance services for persons with autism spectrum disorders

Abstract

The incidence of Autism Spectrum Disorders (ASD) has been increasing over the last two decades. Currently, 1 in 110 children are identified with ASD in the United States (CDC, 2009). ASD refers to a range of neurological disorders that involve some degree of difficulty with communication and interpersonal relationships. The range of the spectrum for autism disorders is wide with those at the higher functioning end often able to lead relatively independent lives and complete academic programs even while demonstrating social awkwardness. Those at the lower functioning end of the autism spectrum often demonstrate physical limitations, may lack speech, and have the inability to relate socially with others. As persons with ASD age, options such as employment become increasingly important as a consideration for long-term personal planning and quality of life. While many challenges exist for persons with ASD in obtaining and maintaining employment, some research is showing that, with effective behavioral and social interventions, employment can occur (Schaller & Yang, 2005). In fact, about 37% of individuals with ASD report having been employed for 12 months or more, four years after exiting high school (Newman, Wagner, Cameto, & Knokey, 2009). However, several studies show that individuals with ASD are more likely to lose their employment for behavioral and social interaction problems rather than their inability to perform assigned work tasks (Dew & Alan, 2007; Hurlbutt & Chalmers, 2004; Unger, 1999). Research has been conducted in the area of autism and employment, but such research has not been reported in a comprehensive evidence review format before. Thus, a systematic review on the effectiveness of adult employment assistance interventions for individuals with ASD would not only demonstrate the extent and magnitude of the interventions’ effects, but also provide ideas for further research that can inform implementation and refinement of related employment-focused programs.
