title: Weight and muscularity concerns as longitudinal predictors of body image among early adolescent boys: a test of the dual pathways model.
abstract: The purpose of this research was to examine the longitudinal contributions of weight loss and muscularity concerns as dual pathways to body image dissatisfaction among early adolescent boys. Study 1 included 67 boys who reported on weight loss concerns, internalized muscular ideal, BMI, and body dissatisfaction during 7th grade and 1 year later. In Study 2, 87 7th and 8th grade boys were assessed in the fall and spring of a school year. The results confirmed that although both weight and muscularity concerns were related to body dissatisfaction, concern with weight loss more strongly detracted from a positive body image than did muscularity concern. The findings are discussed in terms of potential developmental variations in the relative contribution of weight and muscularity to body dissatisfaction among adolescent boys.
