The Environmental Intervention in Children's Homes (ENRICH) study was the first published physical activity intervention undertaken in residential children's homes (RCHs). The study revealed differences in implementation across the homes, which may be a key factor that affects program effectiveness. The purpose of this study was to examine the direct and indirect effects of organizational capacity, provider characteristics, and quality of prevention support system on level of implementation of the ENRICH intervention. This study analyzed the ENRICH process evaluation data collected from 24 RCHs. Bayesian Path analysis was used to examine the direct and indirect effects of organizational capacity, provider characteristics, and quality of prevention support system on level of implementation. Level of implementation across RCHs was variable, ranging from 38 to 97 % (M = 68.3, SD = 14.45). Results revealed that organizational capacity and provider characteristics had significant direct associations with level of implementation. Neither direct nor indirect associations between quality of prevention support system and level of implementation reached statistical significance. Conducting formative assessments on organizational capacity and provider characteristics and incorporating such information in implementation planning may increase the likelihood of achieving higher levels of implementation in future studies.
儿童福利院环境干预（ENRICH）研究是首次发表的针对儿童福利院（RCHs）开展的体育活动干预研究。该研究揭示了各福利院在干预实施方面存在差异，这可能是影响项目效果的关键因素。本研究的目的是探讨组织能力、服务提供者特征以及预防支持系统质量对ENRICH干预实施水平的直接和间接影响。本研究分析了从24家儿童福利院收集的ENRICH过程评估数据。采用贝叶斯路径分析来检验组织能力、服务提供者特征以及预防支持系统质量对实施水平的直接和间接影响。各儿童福利院的实施水平各不相同，范围在38%至97%之间（均值 = 68.3，标准差 = 14.45）。结果显示，组织能力和服务提供者特征与实施水平存在显著的直接关联。预防支持系统质量与实施水平之间的直接和间接关联均未达到统计学显著性。对组织能力和服务提供者特征进行形成性评估，并将此类信息纳入实施计划，可能会增加在未来研究中实现更高实施水平的可能性。
