Predicting Drive for Muscularity Behavioral Engagement from Body Image Attitudes and Emotions.

We examined the potential moderating effects of appearance investment, body image disturbance, and situational body image dysphoria on the drive for muscularity attitudebehavior relationship. Participants (339 British college men, MAGE = 20.00 years, SD = 2.59)
completed drive for muscularity attitude and behavior, appearance investment, body image disturbance, and situational body image dysphoria measures. Results indicated higher levels of appearance investment, body image disturbance, and situational body image dysphoria
were associated with increases in the drive for muscularity attitude’s relationship with physique-enhancing behavioral engagement. Results help extend recent research that has
moved beyond identifying correlates to examining ways that groups of variables interact to predict drive for muscularity behavioral engagement and may contribute to theory development.
