Abstract: | In this study we examined the role of biopsychosocial factors on adolescent boys' body modification strategies over an 8-month period. Participants were 434 adolescent boys aged between 11 and 16 years. The majority of respondents were from Anglo-Australian backgrounds (83%); the others were from Asian and European non-English-speaking backgrounds. The results indicated a consistent relationship between perceived encouragement to engage in body change strategies and increases in adolescents' body modification strategies, including muscle gain, weight gain, and weight loss. In addition, poor parent relations, being younger, and higher scores on the pubertal development scale predicted increased use of food supplements. However, the stability of the body modification strategies and the examined variables over the 8-month period were low. Further studies are needed to examine the stability of adolescent self-perceptions over both longer and shorter periods. Moreover, researchers need to include other factors that may be more relevant for adolescent boys (e.g., involvement in sports). |
