The Psychological Model for Physical Activity Participation and the Physical Estimation and Attraction Scales (PEAS) were developed by Sonstroem using adolescent male subjects. This study investigated the adequacy of the model and instrument for explaining the involvement of college-age females in physical activity. Results indicated that although the model worked similarly for both sexes, there were important differences. Attraction to physical activity, as measured by the Attraction scale, does not contribute to the model for the females in this study, but it does for males. Physical estimation emerged as a key factor, particularly for females, in its relationship with self-esteem, fitness, and physical activity levels. The Estimation Scale appears to be a reliable and powerful instrument for assessing this construct. Future application and development of the model and scales is discussed.
