The type of procedure used to measure a target behavior may directly influence the perceived treatment outcomes. In the present study, we examined the influence of different data-analysis procedures on the outcomes of two commonly used treatments on the vocal stereotypy of 2 children with an autism spectrum disorder. In Study 1, we compared an interrupted and uninterrupted data-analysis procedure to measure vocal stereotypy during the implementation of response interruption and redirection (RIRD). The results showed that the interrupted data-analysis procedure overestimated the effectiveness of RIRD. In Study 2, we examined the influence of different data-analysis procedures on the interpretation of the relative effects of 2 different treatments for vocal stereotypy. Specifically, we compared interrupted and uninterrupted data-analysis procedures during the implementation of RIRD and noncontingent reinforcement (NCR) as a treatment for vocal stereotypy. The results showed that, as in Study 1, the interrupted data-analysis procedure overestimated the effectiveness of RIRD; however, this effect was not apparent with NCR. These findings suggest that different types of data analysis can influence the perceived success of a treatment.
所采用的程序类型用于测量目标行为可能会直接影响到治疗效果的感知。在本研究中，我们研究了两种常用的治疗方法对 2 名自闭症谱系障碍儿童的刻板发声的影响，这两种治疗方法分别是反应中断和重定向（RIRD）和非关联强化（NCR）。在研究 1 中，我们比较了在实施 RIRD 期间使用中断和不中断数据分析程序来测量发声刻板行为。结果表明，中断数据分析程序高估了 RIRD 的有效性。在研究 2 中，我们研究了不同数据分析程序对解释两种不同治疗方法对发声刻板行为的相对效果的影响。具体来说，我们比较了在实施 RIRD 和 NCR 作为发声刻板行为的治疗时使用中断和不中断数据分析程序。结果表明，与研究 1 一样，中断数据分析程序高估了 RIRD 的有效性；然而，NCR 并没有出现这种效果。这些发现表明，不同类型的数据分析会影响治疗效果的感知。
