Conditional probability, calculated using sequential analysis techniques in four time conditions (2, 10, 30, and 60 seconds), provided evidence that successive episodes of self-injury were sequentially dependent. This unique distribution of sequential association for self-injurious behavior (SIB) was not related to frequency or rate of occurrence. Compared with other environmental and behavioral events, the best predictor of SIB was an earlier SIB episode, consistent with a contagious distribution. This study is one of the few in which sequential analysis techniques were applied to data derived from a large group of individuals with severe behavior disorders. It may be the first in which this analytic tool was used to investigate systematically successive occurrences of SIB as it takes place in vivo.
使用顺序分析技术在四个时间条件（2秒、10秒、30秒和60秒）下计算的条件概率表明，连续的自我伤害事件在顺序上是相关的。这种自我伤害行为（SIB）的顺序关联独特分布与发生频率或发生率无关。与其他环境和行为事件相比，SIB的最佳预测指标是更早的SIB事件，这与传染性分布一致。本研究是少数几个将顺序分析技术应用于来自一大群严重行为障碍个体数据的研究之一。它可能是第一个使用这种分析工具来系统研究SIB在体内发生时的连续发生情况的研究。
