We conducted a meta-analysis of single-subject research studies investigating the effectiveness of antecedent strategies grounded in behavioral momentum for improving compliance and on-task performance for students with autism. First, we assessed the research rigor of those studies meeting our inclusionary criteria. Next, in order to apply a universal metric to help determine the effectiveness of this category of antecedent strategies investigated via single-subject research methods, we calculated effect sizes via omnibus improvement rate differences (IRDs). Outcomes provide additional support for behavioral momentum, especially interventions incorporating the high-probability command sequence. Implications for research and practice are discussed, including the consideration of how single-subject research is systematically reviewed to assess the rigor of studies and assist in determining overall intervention effectiveness .
我们对单受试者研究进行了一项荟萃分析，这些研究调查了基于行为动量的先行策略对提高自闭症学生的依从性和任务执行表现的有效性。首先，我们评估了符合我们纳入标准的那些研究的研究严谨性。接下来，为了应用一个通用指标来帮助确定通过单受试者研究方法所调查的这类先行策略的有效性，我们通过综合改善率差异（IRD）计算效应量。结果为行为动量提供了额外支持，特别是包含高概率指令序列的干预措施。讨论了对研究和实践的启示，包括考虑如何系统地审查单受试者研究以评估研究的严谨性并协助确定总体干预效果。
