Social skill interventions have become increasingly popular in recent times, as well as the use of technology to deliver and aid interventions for the autism spectrum disorder (ASD) population. Little research exists on the use of apps to teach social skills to individuals with ASD, in particular the behaviour change procedures that exist within apps. The current review examines the behaviour change procedures that exist within apps according to the Behavior Analyst Certification Board Task List, 5th Edition. A total of 15 apps were included within this review. Results indicate that a variety of behaviour change procedures exist within apps. However, the quality of apps and the number of behaviour change procedures vary across app developers.
