This study aimed to provide an updated and comprehensive review of the efficacy of psychosocial interventions for the employability of individuals with autism spectrum disorder (ASD). Ten studies (423 participants) were identified in the literature. Compared to control groups, the proportion of those who could work was significantly higher among those who had participated in employment support programs and higher, but not significantly, among those who had received communication skills training. The communication skills training group had an improved communication score on employment. This systematic review showed that psychosocial interventions could increase the number of individuals with ASD who are employable and improve their communication skills for employment.
