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.
出走是自闭症谱系障碍（ASD）个体最常见的问题行为形式之一，与致死结果的可能性最大相关。本研究评估了基于功能的治疗方案对两名经常从照顾者身边出走的 ASD 青少年出走行为的影响。功能分析（FA）确定了引发和维持每个青少年出走行为的变量。治疗包括一个连锁时间表，主要由经验衍生的其他行为的差别强化（DRO）、功能性沟通训练（FCT）和消退程序组成。治疗使两名青少年的出走行为都有了显著的临床减少。当将治疗评估扩展到其他环境时，出走行为的减少仍然存在。本研究扩展了关于出走行为的评估和治疗以及涉及 DRO 和 FCT 的连锁时间表治疗的文献。
