Using an analytic framework to identify potential targets and strategies for ecologically based physical activity interventions in middle schools.

The objective was to demonstrate the value of applying an ecological analytic framework to formative data in conjunction with ecological planning frameworks (e.g., intervention mapping) to ensure a high degree of ecological program integration as illustrated through a physical activity program for students in middle school. Eight focus groups were conducted with 38 students in four schools to examine student perceptions of who or what in their school made it easy or difficult for students to be physically active. Qualitative data were used to identify potential intervention targets according to the analytic framework. Frequency analysis revealed that most identified physical activity barriers/facilitators were associated with organization (59.4%) targets. Five different intervention strategies were identified, with organizational modification being most popular. Applying the analytic framework to formative data enabled us to identify potential targets, strategies, and activities for an ecologically based physical-activity-promotion program relevant to the priority population.
