Given the centrality of body dissatisfaction in the manifestation of eating, exercise, and affective disturbances in men, measurement of this construct becomes essential. Across 2 studies with male undergraduates (Ns = 189 and 188), the psychometric properties, including incremental validity and factor structure, of the 25-item Body Parts Satisfaction Scale for Men (BPSS-M) were examined. Three factors--Upper Body, Legs, and Face--that included items measuring both muscularity and leanness were established. The factors were internally consistent and temporally stable (over 6 months), and support was found for their convergent, discriminant, and concurrent validity. Further, we established that, after controlling for social desirability and drive for muscularity, body satisfaction contributes uniquely to men's experience of disordered eating, negative affect and mood, and psychological well-being. The BPSS-M yielded reliable and valid scores with undergraduate men, suggesting that it may be useful for understanding not only body satisfaction but disordered eating and affective disturbances as well.
