Objectification theory has yielded mixed results when utilized to explain male’s body image concerns. This study investigated whether a revised model of objectification theory would represent the processes associated with male’s engagement in muscle dysmorphia characteristics. Specifically the mediating role of body shame, which has previously been used to explain the psychological consequences of self-objectification among women, was substituted for muscular dissatisfaction to capture the male experience. A sample of 257 male (Mage = 29.7, SD = 11.2), the majority from Australia, completed an online questionnaire assessing measures of internalization of the mesomorphic ideal, body surveillance, self-objectification, muscular dissatisfaction, and muscle dysmorphia characteristics. Path analyses were used to investigate the relationships among these variables. Results indicated that internalization of the mesomorphic ideal mediated body surveillance through self-objectification; consistent with previous research on objectification theory. Muscular dissatisfaction mediated the link of body surveillance with muscle dysmorphia characteristics. Additionally, muscular dissatisfaction mediated the link between internalization of the mesomorphic ideal and muscle dysmorphia characteristics. Taken together, these findings support the utility of objectification theory in understanding the processes under which muscle dysmorphia characteristics are likely to emerge
