Brief Summary

While eating disorders in males are often overlooked, up to 7 million men in the United States will experience an eating disorder in their lifetime. Critically, men are less likely to seek treatment for an eating disorder compared to women. Therefore, prevention programs that target male-specific eating disorder risk factors prior to the development of an eating or appearance-related disorder are crucial in reducing eating disorders in this population. Preliminary work by our group established the initial efficacy of a novel program, the Body Project: More than Muscles (MTM) compared to assessment-only control. This study will replicate and extend this research by comparing MTM to a time and attention matched control used in previous eating disorder prevention work, media advocacy (MA).

Outcome Measures

Primary Outcomes (5)

  • Eating Pathology Symptom Inventory (EPSI)

    The EPSI is a 45-item measure scored on a 5-point rating scale with scores ranging from 0 to 4 on individual questions. The EPSI measures eating pathology across eight dimensions with higher scores indicating greater eating pathology.

    change from baseline to immediately post-intervention, change from baseline to 1-month follow-up, and change from baseline to 6-month follow-up

  • Eating Disorder Examination Questionnaire (EDE-Q)

    The EDE-Q is a 28-item measure scored on a 7-point rating scale with scores ranging from 0 to 168 (scores higher than 4 on individual questions are indicative of clinical levels). The EDE-Q is a transdiagnostic measure of Eating Disorder symptoms with high scores indicating elevated eating pathology.

    change from baseline to immediately post-intervention, change from baseline to 1-month follow-up, and change from baseline to 6-month follow-up

  • Muscularity Oriented Eating Test (MOET)

    The MOET is a 15-item measure scored on a 5-point rating scale with scores ranging from 0 to 60. Higher scores on the MOET indicate greater muscularity-related disordered eating.

    change from baseline to immediately post-intervention, change from baseline to 1-month follow-up, and change from baseline to 6-month follow-up

  • Muscle Dysmorphic Disorder Inventory (MDDI)

    The MDDI is a 13-item measure for muscle dysmorphia symptoms, which is a common feature of Eating Disorders in men. Items are scored 0 (never) to 4 (always) with higher scores indicating greater muscle dysmorphic symptoms. Scores on this measure range 0 to 52.

    change from baseline to immediately post-intervention, change from baseline to 1-month follow-up, and change from baseline to 6-month follow-up

  • Eating Pathology Symptom Inventory-Clinician Rated Version (EPSI-CRV

    The EPSI-CRV is a semi-structured interview that assesses dimensional constructs of psychopathology associated with Diagnostic and Statistical Manual-5 Eating Disorders. The interview will take approximately 40 minutes to complete.

    Change from baseline to 6-month follow-up related to dimensional changes in Eating Disorder-related psychopathology

Secondary Outcomes (10)

  • Sociocultural Attitudes Towards Appearance Questionnaire (SATAQ)

    change from baseline to immediately post-intervention, change from baseline to 1-month follow-up, and change from baseline to 6-month follow-up

  • Drive for Muscularity Scale (DMS)

    change from baseline to immediately post-intervention, change from baseline to 1-month follow-up, and change from baseline to 6-month follow-up

  • Male Body Attitudes Scale (MBAS)

    change from baseline to immediately post-intervention, change from baseline to 1-month follow-up, and change from baseline to 6-month follow-up

  • Self-Objectification Questionnaire (SOQ)

    change from baseline to immediately post-intervention, change from baseline to 1-month follow-up, and change from baseline to 6-month follow-up

  • Obligatory Exercise Questionnaire (OEQ)

    change from baseline to immediately post-intervention, change from baseline to 1-month follow-up, and change from baseline to 6-month follow-up

  • +5 more secondary outcomes

Study Arms (2)

Media Advocacy (MA)

ACTIVE COMPARATOR

Participants assigned to this condition take place in a time and attention-matched active control where they discuss the role of media in promoting the body ideal.

Behavioral: Media Advocacy (MA)

Body Project: More than Muscles (MTM)

EXPERIMENTAL

Participants assigned to this condition take part in a two-session intervention based on dissonance theory which encourages them to challenge the body ideal.

Behavioral: More than Muscles (MTM)

Interventions

MA content generally centers on acknowledging and discussing the role the media has on shaping body image ideals. Session 1: In session 1, similar to MTM, the primary activities will include: (1) describing the ideal body for men in our culture, (2) discussing how the media impacts this ideal, with a particular focus on advertising. Following this, participants will (3) watch a video on how the media influences body image among men, and the consequences of internalizing these messages. Session 2: In session 2, content will continue by further discussion of the video showed in session 1, with participants sharing their reactions. Next, the group discusses the attainability of the ideal as well as discusses other forms of media (e.g., social media) and how it impacts body image.

Media Advocacy (MA)

In session 1, the primary activities are: 1) define the "ideal" body type for men in our culture, 2) discuss the origin and perpetration of the "ideal," 3) brainstorm the costs of pursuing the "ideal," 4) participate in a verbal challenge during which participants counter the "ideal" message, and (5) are asked to complete three "homework" assignments (i.e., a letter to an adolescent boy, a behavioral challenge, and a mirror exposure assignment). In session 2, the primary activities are: 1) reviewing homework, 2) engage in role-plays to counter/discourage pursuit of the "ideal," 3) discuss ways to challenge and avoid "negative body talk" statements, 4) list ways to resist the pressure to pursue this "ideal" both individually and as a group within the larger community (i.e., body activism), 5) discuss barriers to body activism and strategies to overcome those barriers, and 6) individually select an exit exercise to continue to actively challenge the appearance ideal.

Model Details: Participants will briefly be screened for eligibility criteria by phone. Eligible participants will be assessed using two structured clinical interviews (SCID-5 \& EPSI-CRV) and complete a set of self-report measures at baseline. Following assessment participants will be randomized into one of two groups. One group will receive a dissonance-based intervention known as the More than Muscles (MTM), while other participants will engage in a Media Advocacy (MA) active control. Participants will complete the same set of self-report measures from baseline, after their final group, at 1-month follow-up and at 6-month follow-up. During the 6-month follow-up participants will also be reassessed using the same structured clinical interviews at baseline.
