Purpose: Previous research has identified termination of interruptions to repetitive behaviour as a reinforcer capable of maintaining problem behaviour. Effective treatments have included functional communication training and multiple schedules of reinforcement.

Methods: In the present study, a functional analysis determined that the aggression of an eight-year-old boy with autism spectrum disorder was maintained by termination of interruptions of repetitive behaviour. An intervention was implemented consisting of differential reinforcement of other behaviour and response cost.

Results: The intervention produced and maintained a reduction in aggression and increased tolerance for interruptions of systematically increasing durations.

Conclusions: This case study demonstrates an alternative approach to the treatment of problem behaviours such as aggression maintained by termination of repetitive behaviour that includes teaching the individual to tolerate interruption of repetitive behavior.

目的：先前的研究已经确定，终止重复性行为的中断是一种能够维持问题行为的增强器。有效的治疗方法包括功能性沟通训练和多种强化计划。

方法：在本研究中，一项功能分析确定，通过终止重复性行为的中断，可以维持一名八岁的自闭症谱系障碍男孩的侵略性。实施了一项干预措施，其中包括对其他行为和响应成本的不同强化。

结果：该干预措施能够使侵略性降低并保持不变，并能持续增加持续性干扰的耐受性。

结论：本案例研究表明了一种解决问题行为的替代方法，例如通过终止重复行为来维持侵略性，其中包括教导个人容忍重复行为的中断。
