Achieving adequate physical activity is an important health goal that many elementary school students are not meeting during the school day. The physical activity leadership (PAL) Program was designed to provide individually tailored supports to improve the quantity and quality of physical activity in schools, as well as promote improvements in self-efficacy, attitudes, and motivation for physical activity. Self-efficacy, attitudes, and motivation are three key factors in predicting increases in physical activity, and consequently serve as the cognitive-affective variables examined in the present study. A sample of 117 fourth- and fifth-grade students and 22 teachers completed several quantitative and open-ended feedback measures before and after a district-wide physical activity intervention. Results indicated the PAL Program was highly beneficial to all participants, and several key measures (negative attitudes, motivation to exercise, and perceptions of physical ability) were significantly impacted in the anticipated direction. Open-ended feedback data collected from teachers involved also suggests that the program was well-received and was perceived as beneficial. This study provides additional evidence in support of individually tailored physical education interventions.
