Despite its importance within behavioural intervention, it remains unclear how best to achieve high procedural fidelity. This paper reviewed studies on improving procedural fidelity of behavioural interventions for individuals with intellectual and developmental disabilities (IDD).
A systematic literature search was conducted, which identified 20 studies meeting inclusion criteria. Data were extracted on study design, participant characteristics, intervention, target behaviours, effect sizes, maintenance, generalization and social validity. A quality rating was also applied.
A total of 100 participants took part in the included studies. Most participants were teachers working with children in school settings. There was a significant positive correlation between level of procedural fidelity and client outcomes. Feedback was the most commonly employed intervention to improve procedural fidelity.
More research should be conducted in environments with high levels of variability such as community homes to determine how to reach and maintain high levels of procedural fidelity.
尽管在行为干预中非常重要，但仍不清楚如何最好地实现高程序保真度。本文综述了旨在提高智力和发育障碍（IDD）个体行为干预程序保真度的研究。
进行了系统的文献检索，确定了符合纳入标准的 20 项研究。提取了研究设计、参与者特征、干预、目标行为、效果大小、维持、泛化和社会有效性的数据。还进行了质量评级。
共有 100 名参与者参加了纳入的研究。大多数参与者是在学校环境中与儿童一起工作的教师。程序保真度水平与客户结果之间存在显著的正相关关系。反馈是提高程序保真度最常用的干预措施。
应在具有高度可变性的环境（如社区家庭）中进行更多的研究，以确定如何达到并保持高程序保真度。
