OBJECTIVE: The transformation framework conceptualizes social media as reshaping traditional peer influences and could enhance understanding of disordered eating. This cross-sectional study examined (1) independent associations of friend dieting and social media exposure with eating pathology, (2) whether social media exposure moderates the relationship between friend dieting and eating pathology, and (3) explored whether sex and age moderate independent and combined effects of friend dieting and social media exposure on eating pathology.
METHOD: A large sample of men and women (N = 1860) ranging in age from 28 to 69 years (M = 47.24 years, SD = 10.71), completed surveys assessing friends' behaviors, social media exposure, and eating pathology.
RESULTS: Friend dieting and social media exposure showed independent associations with bulimic symptoms and drive for thinness. Greater social media exposure strengthened the relationship between friend dieting and bulimic symptoms in younger men and older women, and between friend dieting and drive for thinness in younger men and men at the mean age.
DISCUSSION: Findings partially support hypotheses from the transformation framework, with the most consistent support found for younger men. Future work should examine how social media exposure amplifies the frequency, immediacy, and impact of peer influence on disordered eating to inform social media literacy programs tailored to adults.
