Differences in psychosocial constructs among elementary school staff that implement physical activity programs: a step in designing implementation strategies.

Multiple types of school staff members (e.g., classroom teachers, principals) are involved in implementing physical activity programs (e.g., classroom-based, gym), but factors specific to their job responsibilities may inhibit their ability to implement programming effectively. Thus, implementation strategies tailored by job type may be needed. We compare perceptions of behavioral constructs related to implementation of school-based physical activity programs, by job type, among school staff. School staff (n = 139), including principals/assistant principals (n = 21), physical education teachers (n = 41), and classroom teachers (n = 77), from elementary schools (n = 25), completed a cross-sectional survey measuring perceptions of attitudes, barriers, knowledge, and outcome expectations related to the implementation of physical activity programs. We compared constructs between job types using complex samples general linear models. Classroom teachers reported more perceived implementation barriers, lower physical activity knowledge, and lower outcome expectations than physical education teachers. Principals reported more perceived implementation barriers than physical education teachers. Classroom teachers reported lower physical activity knowledge than principals. Attitudes towards physical activity were not different by job type. Each job type has a unique constellation of factors affecting their capacity to implement physical activity programs. Understanding these differences enables tailoring of implementation strategies by job type.
