This study examined whether the media literacy program, ARMED, is an effective prevention intervention for college women at low- or high-risk for an eating disorder. Changes in eating disorder risk factors were assessed in low- ( n = 26) and high-risk ( n = 19) women participating in a two-session media literacy intervention as compared to low- ( n = 31) and high-risk ( n = 16) controls. Women at high-risk for an eating disorder reported significant decreases in body dissatisfaction, drive for thinness, feelings of ineffectiveness, and internalization of societal standards of beauty after participating in ARMED, whereas control participants did not. No significant decreases in perfectionism, physical appearance comparisons, or awareness of societal standards of beauty were reported among high-risk participants. Changes in eating disorder risk factors were not found among low-risk participants, regardless of treatment condition. Findings suggest that media literacy may be an effective secondary prevention intervention for eating disorders.
