A Randomized Controlled Trial of The Body Project: More Than Muscles for Males With Body Dissatisfaction

BACKGROUND & PURPOSE The current project sought to examine the acceptability and efficacy of a cognitive dissonance-based (DB) eating disorder prevention program for college-aged men with body image concerns. Eating disorders represent a public health problem for which efficacious, disseminable treatments largely remain unknown, particularly for males. Epidemiological data support the increasing prevalence of eating disorders and body image concerns among men; however, few programs have been developed to address concerns relevant to men, and many men feel uncomfortable in programs that identify eating disorders as a "female" problem. Given that eating disorders are particularly difficult to treat, disseminable interventions that can target high-risk groups prior to eating disorder onset may be the best way to reduce the public health burden associated with eating disorders. As body image concerns represent the most potent and consistent risk factor for developing eating disorders in males and females, men with body image concerns represent one such high-risk, but underserved, group.

Recent prevention research has used DB principles to challenge thin-ideal internalization to decrease the likelihood of developing an eating disorder in female youth. Additionally, the investigators recently adapted and evaluated a DB program for gay males (The PRIDE Body Project), who represent another high-risk group among men. Dissonance theory states that when individuals engage in counter-attitudinal behavior they experience psychological discomfort, leading them to alter their attitudes to be congruent with their behavior. Several studies have supported the efficacy of DB programs in reducing eating disorder risk among females and results from The PRIDE Body Project extends the efficacy of these programs to gay males. These DB interventions have utilized peer co-leaders, capitalizing on the importance of peer influences on eating behaviors among college-aged females and males.

To date, other than The PRIDE Body Project, no studies have examined eating disorder prevention interventions for high-risk groups of males. Notably, the success of The PRIDE Body Project and several lines of research support that adapting a DB program may also be helpful in reducing eating disorder risk among young men with body image concerns. First, internalization of the mesomorphic ideal plays a central role in risk for developing eating pathology in males. Thus, an intervention targeting internalization of this body ideal may be particularly helpful for males. Second, studies support that peers influence body dissatisfaction and disordered eating in males concurrently and prospectively through socialization. This suggests that men, regardless of sexual orientation, may benefit from a peer-led DB program to address body image concerns. This work could fill a critical gap in the care provided to a growing demographic among those who suffer from eating disorders.

Thus, the aim of the present study was to determine the acceptability and efficacy of adapting a cognitive DB intervention for use in college-aged men with body image concerns. 112 men with body image concerns were recruited to participate in a randomized controlled trial (RCT), in which they were randomized into either a DB intervention (n=52) or wait list control (WL) condition (n=60).

The investigators hypothesized that: (1) The men in the DB group would show significantly greater reductions on all measures compared to men in the WL group; and (2) Differences between groups would be maintained at 4-week follow-up.
