Acceptance and Commitment Therapy (ACT) is an intervention that fosters acceptance of uncomfortable thoughts and emotions as a coping strategy, and encourages engagement in valued behavior in the presence of these emotions. ACT has been successfully applied to parents with similar mental health presentations. Using a randomized controlled study design, investigators seek to gather initial data on the treatment feasibility and acceptability, detect treatment effects in a cohort of parents who have a child (under the age of 15) with autism spectrum disorder.
