Functional communication training (FCT) is an evidence-based practice used to mitigate challenging behavior by increasing functional communication skills. To increase the practicality and feasibility of FCT in natural settings, thinning schedules of reinforcement are typically programmed following FCT. In this review, we meta-analyzed 28 studies that incorporated a thinning schedule procedure following FCT for 51 children with intellectual and developmental disabilities ages 8 and younger. Using Tau-U, the results demonstrated overall moderate effect sizes for both challenging behavior and functional communication responses. Additionally, moderator analyses pertaining to participant characteristics, interventions, and study quality were conducted. Thinning procedures were most effective for children who had stronger communication repertoire. Implications for future research and practice are discussed.
功能沟通训练（FCT）是一种循证实践，用于通过增加功能性沟通技能来减轻挑战性行为。为了提高 FCT 在自然环境中的实用性和可行性，通常会在 FCT 之后制定强化时间表的稀疏化程序。在这项综述中，我们对 28 项研究进行了荟萃分析，这些研究在对 51 名年龄在 8 岁及以下的智力和发育障碍儿童进行 FCT 后纳入了稀疏化时间表程序。使用 Tau-U，结果表明，挑战性行为和功能性沟通反应的总体效果中等。此外，还对参与者特征、干预措施和研究质量进行了调节分析。稀疏化程序对具有更强沟通能力的儿童最有效。讨论了对未来研究和实践的影响。
