目的：本研究旨在对一系列单例实验设计研究进行量化和综合，研究声音产生治疗的效果，这是一种对获得性语言失用症（AOS）的发音-运动学治疗。主要目的是对汇总的声音制作处理数据进行荟萃分析，以便提供基准，作为变化幅度的指标。其他分析探讨了影响效果大小和性能水平的各种因素。方法：计算10项调查中24名参与者的治疗项目和未治疗项目的效应量。基准以效应大小分布的四分位数计算。进行相关分析以检验(a)治疗结束时的表现相对于随访表现，(b)训练项目相对于未训练项目的反应，以及(c)相对于参与者变量的效应大小。结果：效应量主要是大的和正的；处理项目的基准比未处理项目的基准大。治疗结束与随访表现呈正相关，反应泛化与AOS严重程度呈正相关。结论：这些基准可能有助于在临床和研究环境中使用类似的结果测量来评估干预措施对AOS患者的影响。
Purpose: This investigation was designed to provide a quantification and synthesis of a series of single-case experimental design investigations into the effects of sound production treatment, an articulatory-kinematic treatment for acquired apraxia of speech (AOS). The main purpose was to perform a meta-analysis of aggregated sound production treatment data in order to provide benchmarks to serve as indicators of magnitude of change. Additional analyses explored various factors influencing effect sizes and level of performance.Method: Effect sizes were calculated for treated and untreated items for 24 participants across 10 investigations. Benchmarks were calculated as the quartiles of the distributions of the effect sizes. Correlational analyses were performed to examine (a) end-of-treatment performance relative to follow-up performance, (b) response of trained items relative to untrained items, and (c) effect size relative to participant variables.Results: Effect sizes were predominantly large and positive; benchmarks for treated items were larger than those for untreated items. End of treatment and follow-up performance were positively correlated, and response generalization was positively correlated with AOS severity.Conclusion: These benchmarks may assist in evaluating the effects of interventions for individuals with AOS utilizing similar outcome measures in both clinical and research settings.
