Adolescents with autism spectrum disorder (ASD) without an intellectual disability have daily living skills (DLS) impairments. An initial feasibility pilot of Surviving and Thriving in the Real World (STRW), a group intervention that targets DLS, demonstrated significant improvements. A pilot RCT of STRW was conducted to extend these findings. Twelve adolescents with ASD were randomized to the treatment or waitlist groups. The treatment group had significant DLS improvements on the Vineland Adaptive Behavior Scales, 3rd Edition and the DLS goal attainment scale. Four adolescents from the waitlist crossed over and completed STRW. Entire sample analyses with 10 participants demonstrated large DLS gains. Results provide further evidence of the efficacy of STRW for closing the gap between DLS and chronological age.
