This multiple-study experiment evaluated the utility of assessing and treating severe self-injurious behavior SIB based on the outcomes of a functional analysis of precursor behavior. In Study 1, a precursor to SIB was identified using descriptive assessment and conditional probability analyses. In Study 2, a functional analysis of precursor behavior was conducted. Finally, study 3 evaluated the effects of a treatment in which precursor behavior produced the maintaining variable identified in the precursor functional analysis. Studies 1 and 3 were conducted in two settings in the participants natural environment, where data collection was ongoing throughout the course of the study. Results showed that it was possible to identify a precursor to infrequent but severe SIB, that a functional analysis of precursor behavior suggested a clear operant function, and that treatment based on the results of the precursor functional analysis reduced SIB in the natural environment.
这项多研究实验评估了根据前驱行为的功能分析结果来评估和治疗严重自伤行为 (SIB) 的效用。在研究 1 中，使用描述性评估和条件概率分析确定了 SIB 的前驱。在研究 2 中，进行了前驱行为的功能分析。最后，研究 3 评估了一种治疗方法的效果，其中前驱行为产生了在前驱功能分析中确定的维持变量。研究 1 和研究 3 在参与者自然环境中的两个环境中进行，在整个研究过程中都在持续收集数据。结果表明，有可能识别出一种罕见但严重的 SIB 的前驱，前驱行为的功能分析表明存在明确的操作性功能，并且基于前驱功能分析的结果进行治疗可以减少自然环境中的 SIB。
