Functional Analysis and Chained Schedule Treatment of Elopement in Teens with Autism Spectrum Disorder.

Elopement is one of the most common forms of problem behavior for individuals with autism spectrum disorder (ASD) and is associated with the greatest probability of a lethal outcome. This study evaluated the effects of a function-based treatment package on elopement for two teenage boys with ASD who eloped frequently from caregivers. Functional analyses (FA) identified the variables that evoked and maintained each teen's elopement. Treatment involved a chained schedule comprised primarily of empirically derived differential reinforcement of other behavior (DRO), functional communication training (FCT), and extinction procedures. The treatment produced clinically significant decreases in elopement for both teens. Decreases in elopement maintained when the treatment evaluation was extended to additional contexts. The current study extends the literature on assessment and treatment of elopement and chained schedule treatments that involve both DRO and FCT.
