Acceptance and commitment therapy (ACT) has shown to be an effective intervention in promoting psychological health. This systematic review aimed to establish the effectiveness of ACT for adults with autism and/or intellectual disabilities.


Three databases were systematically reviewed (PsycInfo, PubMed, and MEDLINE) using PRISMA guidelines.


After initial screening and removal of duplicates, 216 potential papers were identified of which eight papers were identified and included in the systematic review.


The findings suggest that ACT may be a useful intervention in reducing psychological difficulties and improving adaptive functioning skills. However the small number of individuals included in the review, as well as the poor methodological rigour of the studies included limits conclusive findings at present.
