This study reports the effects of a structural intervention, ENRICH (Environmental Interventions in Children's Homes) which targeted the physical and social environment within residential children's homes (RCHs) to increase physical activity (PA) among residents (n=799). Participating RCHs (n=29) were randomized to Early (n=17) or Delayed (n=12) groups from 2004 to 2006 and 2006 to 2008, respectively. Children's PA was measured at three time periods (2004, 2006, 2008). Intent-to-treat analysis revealed no intervention impact on PA. Subsequent analyses used process evaluation data to group organizations into high and low PA-promoting RCHs to compare PA level, controlling for assignment to condition. Organizations with high PA-promoting environments were found to have more active youth. Utility of a comprehensive implementation monitoring plan and the need for formative assessment of organizational capacity is discussed.
本研究报告了一项结构性干预措施——“丰富儿童之家环境”（ENRICH，即儿童之家的环境干预）的效果。该干预措施旨在改善儿童福利院（RCHs）的物理和社会环境，以增加福利院居民（n = 799）的身体活动（PA）。参与研究的儿童福利院（n = 29）在2004年至2006年以及2006年至2008年期间分别被随机分为早期组（n = 17）和延迟组（n = 12）。在三个时间段（2004年、2006年、2008年）对儿童的身体活动进行了测量。意向性分析显示干预对身体活动没有影响。随后的分析使用过程评估数据将各机构分为促进身体活动水平高和低的儿童福利院，以比较身体活动水平，并对分组情况进行控制。结果发现，促进身体活动环境良好的机构中有更活跃的青少年。本文还讨论了综合实施监测计划的效用以及对组织能力进行形成性评估的必要性。
