title: Factors Influencing Implementation of a Physical Activity Intervention in Residential Children's Homes.
abstract: 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.
