Masculine gender role stress and the pursuit of muscularity.

The relationship between masculine gender role stress and body change was examined in 129 men, aged between 18 and 40 years (M = 24.38; SD = 6.04), who completed the Masculine Gender Role Stress scale (MGRS), the Drive for Muscularity Scale, the Eating Disorder Inventory, and the Eating Disorder Examination-Questionnaire. Significant relationships were observed between MGRS and drive for muscularity and, to a lesser extent, drive for thinness and disordered eating symptomatology. These relationships were mediated by body dissatisfaction, and several of the relationships were positively moderated by self-reported affective problems and personal ineffectiveness. Although interpretation of the results is limited by the cross-sectional design employed, the results are consistent with the proposition that a fear of deviating from the masculine gender role, particularly in men who feel ineffective and who have difficulty controlling and accessing their emotions, is related to concern with, and pursuit of, muscularity and leanness.
