N2 - Objective: To investigate if baseline depression moderated response to Media Smart, an 8-lesson school-based program previously found to achieve a long-term risk reduction effect in young adolescents. Method: 540 Grade 8 students (M age=13.62 years, SD= .37) from 4 schools participated with 11 classes receiving the Media Smart program (126 girls; 107 boys) and 13 comparison classes receiving their normal lessons (147 girls; 160 boys). Shape and weight concern, media internalization, body dissatisfaction, dieting, ineffectiveness, and perceived pressure were the outcome variables. Results: Moderation was indicated by significant interaction effects for group (Media Smart; Control)×moderator (high depression; low depression)×time (post-program; 6-month follow-up; 2.5-year follow-up), with baseline entered as a covariate. Such effects were found for shape and weight concern, media internalization, body dissatisfaction, ineffectiveness and perceived pressure. Post-hoc testing found high depression Media Smart participants scored significantly lower than their control counterparts at post-program on shape and weight concern, media internalization and dieting, whereas low depression Media Smart participants scored significantly lower on shape and weight concern at 2.5-year follow-up. Discussion: Media Smart achieved a reduction in eating disorder risk factors for high-depression participants and a reduced rate of growth in risk factor scores for low-depression participants.Trial registry name: Australian New Zealand Clinical Trials Registry.URL: http://www.anzctr.org.au.Registration identification number: ACTRN12608000545369.
