Prior studies on treatment relapse have typically examined the prevalence of resurgence or renewal of target behavior (e.g., destructive behavior) in isolation. This study analyzed both types of relapse during 25 consecutive treatments involving functional communication training during worsening reinforcement conditions for alternative behavior (i.e., schedule thinning) or following context changes. We also examined disruption of alternative behavior (i.e., functional communication requests, compliance). Resurgence and renewal of destructive behavior occurred in 76% and 69% of treatments, respectively, and in approximately a third of changes in reinforcement or context. Relapse of destructive behavior predicted alternative-response disruption and vice versa; the co-occurrence of these two events always exceeded the background probabilities of either event occurring in isolation. General reductions in treatment efficacy occurred across changes in reinforcement or context, with no apparent decrease in likelihood in later transitions. We discuss implications of our findings with respect to future studies examining treatment durability.

重度破坏行为治疗中复吸的范围及特点

先前关于治疗复发的研究通常单独检查目标行为（例如，破坏性行为）的复发或更新的普遍性。本研究分析了 25 次连续治疗期间的两种类型的复发，这些治疗涉及在替代行为（即日程安排变薄）的恶化强化条件下或以下情境变化期间的功能沟通训练。我们还检查了替代行为的中断（即功能性通信请求、合规性）。破坏性行为的复苏和更新分别发生在 76% 和 69% 的治疗中，以及大约三分之一的强化或环境变化。破坏性行为的复发预示着替代反应的中断，反之亦然；这两个事件的同时发生总是超过任一事件单独发生的背景概率。治疗效果的普遍降低发生在强化物或背景的变化中，而在后来的转变中可能性没有明显降低。我们讨论了我们的研究结果对未来研究治疗持久性的影响。
