Many behavior analysts do not conduct a functional analysis (FA) prior to treatment in a clinical setting (e.g., Roscoe et al., 2015). When asked for an explanation, respondents commonly report that an FA is too time consuming. One way to address this perceived constraint is to evaluate the utility of an abbreviated FA with 5-min session durations. In the current study, 2 independent FAs, 1 with 5-min sessions and 1 with 10-min sessions, were conducted for the problem behavior of 5 individuals diagnosed with autism spectrum disorder (ASD). For all participants, the 5- and 10-min session duration FAs yielded the same identified function of problem behavior: escape from demands. A brief differential reinforcement of alternative behavior (DRA) analysis was subsequently conducted and found to be effective at decreasing problem behavior and increasing an appropriate communication response across participants. These findings demonstrate the utility of conducting an FA using briefer session durations followed by a brief DRA analysis.

简短和延长会话持续时间功能分析的比较

许多行为分析师在临床环境中的治疗前不进行功能分析 (FA)（例如，Roscoe 等，2015）。当被要求解释时，受访者通常表示 FA 太耗时了。解决这种感知约束的一种方法是评估具有 5 分钟会话持续时间的缩写 FA 的效用。在当前的研究中，针对 5 名被诊断患有自闭症谱系障碍 (ASD) 的人的问题行为，进行了 2 次独立的 FA，1 次 5 分钟会话和 1 次 10 分钟会话。对于所有参与者，5 分钟和 10 分钟的会话持续时间 FA 产生了相同的问题行为功能：逃避需求。随后对替代行为 (DRA) 分析进行了简短的差异强化分析，发现其可有效减少问题行为并增加参与者之间的适当沟通反应。这些发现证明了使用较短的会话持续时间和简短的 DRA 分析进行 FA 的效用。
