Objective: The present study assesses stigma, attitudes, and strategies of college students in intervening with peers demonstrating disordered eating behaviors.Method: Four hundred and eighty nine college students (384 women) completed questionnaires that assessed eating disorder symptoms and bystander attitudes adapted for disordered eating. Participants read one of three vignettes of a 20-yearold hypothetical peer displaying symptoms of disordered eating aligned with bulimia nervosa, anorexia nervosa, or binge-eating disorder; participants then described whether the vignette subject had a problem, what the problem was, and strategies for intervention. Relationships among eating disorder history, bystander attitudes, demographics, and intention to intervene in disordered eating were assessed using descriptive and regressive analyses; peer intervention strategies were organized and evaluated for frequencies of responses.Results: Demographics (female-identification) and familiarity with disordered eating were associated with likelihood to intervene in disordered eating. Most students recognized that the peer had a problem, but fewer than half believed the problem was disordered eating; nearly a quarter (22%) of the students stated that they would be uncomfortable talking to a peer about disordered eating. The majority of students cited vague or nonproblem-related intervention strategies (62%), followed by emotion-focused strategies (22.5%), or body and behavior-focused strategies (15%).Discussion: College students, particularly women and those with previous exposure to eating disorders, are likely to intervene peers disordered eating. However, students tend to use vague or body-focused intervention strategies. Bystander intervention training that provides rationale and rehearsal for supportive communication strategies is needed to address students' lack of intervention skills, particularly among men.
