Sonstroem's psychological model for physical activity offers a testable theory for understanding certain aspects of involvement and outcomes among adolescent boys. The usefulness of the model for other populations cannot be clarified, however, until the psychometric properties of its technology, the Physical Estimation and Attraction Scales (PEAS), are known for the groups studied. As a step in this direction, the factorial validity of PEAS responses among college males (N = 488) and females (N = 347) was examined. An independent group of college females (N =413) was also sampled to examine the general ability of the initial findings. These results revealed a robust factor of items that apparently tap perceptions of general physical competence and a perceived strength factor. These emerged across samples and analyses and were not gender-specific. Investigators using the PEAS with adult populations should consider its unique factor structure in the process of testing Sonstroem's physical activity model. Psychometric research regarding revision of the PEAS for adult populations is recommended with the aim of reducing instrument length while maintaining construct validity and measurement precision.
