Resurgence following expanded-operant treatments (i.e., increasing the number or variability of alternative responses to problem behavior) has been the focus of numerous studies over the last 5 years. Researchers have evaluated several techniques for expanding the operant such as serial-, lag-, and concurrent-training procedures. Given the increasing number of recent studies on the topic, the various forms of training used, and the variability in outcomes, it is critical to review this area of research and identify future directions. Our brief review identified 10 published studies and eight unpublished theses or dissertations on this topic; however, only 3 published studies directly evaluated expanded-operant treatments as a strategy for relapse mitigation. All three studies evaluated serial-training procedures, and results across the studies were inconsistent. We summarize the findings of each study and provide recommendations for future research.

在过去 5 年中，扩大手术治疗后的复兴（即增加对问题行为的替代反应的数量或可变性）一直是众多研究的焦点。研究人员评估了几种扩展操作的技术，例如串行、滞后和并发训练程序。鉴于最近关于该主题的研究越来越多、所使用的培训形式多种多样以及结果的可变性，审查这一研究领域并确定未来方向至关重要。我们的简短审查确定了 10 项已发表的研究和 8 篇未发表的关于该主题的论文或论文；然而，只有 3 项已发表的研究直接评估了扩大手术治疗作为缓解复发的策略。这三项研究都评估了连续训练程序，整个研究的结果不一致。我们总结了每项研究的结果，并为未来的研究提供了建议。
