Abstract
OBJECTIVE: Psychological problems associated with isolation and mistrust are common among young adults with autism spectrum disorder (ASD). Schema therapy (ST) has recently been shown to be effective against chronic personality problems of various mental disorders, including personality disorders. This pilot clinical trial aimed to explore the feasibility and acceptability of ST in young adults with high-functioning ASD. RESULTS: Following the intervention, a significant reduction in early maladaptive schemas and improvements in quality of life and social adjustment were observed. ST may be feasible and is applicable to young adults with HF-ASD. Trial registration UMIN000014535; registered on July 11, 2014.
