Despite the efficacy of behavioral interventions, resurgence of challenging behavior (e.g., aggression, self-injury) following successful treatment can still occur. Applied work has focused on identifying treatment-related variables thought to affect the occurrence and magnitude of resurgence. The current study describes the relation between several variables (i.e., phase duration, response rates in baseline and treatment, obtained rates of reinforcement, downshift in reinforcement step size) and resurgence in a retrospective consecutive controlled case series of 46 treatment applications for challenging behavior conducted in an inpatient setting. Only the downshift in reinforcement (e.g., schedule-thinning) step size was correlated with the magnitude of resurgence. These results are consistent with recent findings suggesting that treatment duration and other factors have inconsistent effects on resurgence of challenging behavior.
尽管行为干预措施具有疗效，但在成功治疗后，挑战性行为（例如攻击行为、自伤行为）仍可能复发。应用研究的重点是确定被认为会影响复发的发生和程度的治疗相关变量。本研究在住院环境中对 46 项挑战性行为治疗应用的回顾性连续对照病例系列中，描述了几个变量（即阶段持续时间、基线和治疗中的反应率、获得的强化率、强化步长的降低）与复发之间的关系。只有强化（例如，时间表变薄）步长的降低与复发的程度相关。这些结果与最近的研究结果一致，即治疗持续时间和其他因素对挑战性行为的复发有不一致的影响。
