Transdiagnostic Group Therapy (GBAT) for Autistic Adults With Personalized Therapeutics

The purpose of this study is to build upon an earlier study that evaluated the use of a 10-week transdiagnostic Group Behavioral Activation Therapy (GBAT), a telehealth delivered intervention, as a cost effective and accessible way to treat symptoms of anxiety and depression in autistic adults. The current study will pilot and compare relative feasibility, acceptability, and preliminary efficacy of three adapted GBAT groups and a Watchful Waiting (WW) group. The three groups include GBAT+Individual (GBAT+I; individual sessions to supplement the 10 group sessions), GBAT+Engagement Booster (GBAT+E; supplemental materials), and GBAT+Both (GBAT+IE individual sessions and supplemental materials).
