We conducted descriptive observations of severe problem behavior for 2 individuals with autism to identify precursors to problem behavior. Several comparative probability analyses were conducted in addition to lag-sequential analyses using the descriptive data. Results of the descriptive analyses showed that the probability of the potential precursor was greater given problem behavior compared to the unconditional probability of the potential precursor. Results of the lag-sequential analyses showed a marked increase in the probability of a potential precursor in the 1-s intervals immediately preceding an instance of problem behavior, and that the probability of problem behavior was highest in the 1-s intervals immediately following an instance of the precursor. We then conducted separate functional analyses of problem behavior and the precursor to identify respective operant functions. Results of the functional analyses showed that both problem behavior and the precursor served the same operant functions. These results replicate prior experimental analyses on the relation between problem behavior and precursors and extend prior research by illustrating a quantitative method to identify precursors to more severe problem behavior.

我们对两名自闭症患者的严重问题行为进行了描述性观察，以确定问题行为的先兆。除了使用描述性数据进行滞后序列分析外，还进行了几次比较概率分析。描述性分析结果表明，与潜在先兆的无条件概率相比，在出现问题行为时，潜在先兆的概率更高。滞后序列分析结果表明，在问题行为发生前的1秒间隔内，潜在先兆的概率显著增加，并且在先兆出现后的1秒间隔内，问题行为的概率最高。然后，我们分别对问题行为和先兆进行了功能分析，以确定各自的操作性功能。功能分析结果表明，问题行为和先兆都具有相同的操作性功能。这些结果重复了之前关于问题行为与先兆之间关系的实验分析，并通过说明一种定量方法来识别更严重问题行为的先兆，扩展了先前的研究。
