Abstract
Results Moderation was indicated by significant interaction effects for group (Media Smart; Life Smart; HELPP; Control) X moderator (high shape and weight concern; low shape and weight concern) X time (post-program; 6-month followup; 12-month follow-up), with baseline entered as a covariate. Such effects were found for shape concern, weight concern, eating concern, regular eating, body dissatisfaction, and physical activity. Post-hoc testing found Media Smart participants with high baseline shape and weight concern experienced a reduction in risk at 12-month follow-up for 4 of the 6 variables. Discussion This study shows it is possible for a school-based program to reduce eating disorder risk factors in participants with high baseline risk of an eating disorder.
