Evaluating a School-Based Intervention for Body Image (‘Dove Confident Me: 5-Part Body Confidence Workshops for Schools’) Among Adolescent Girls and Boys: Results from a Cluster Randomized Controlled Effectiveness Trial

An abstract of the study by Atkinson et al evaluating the effectiveness and acceptability of a universal, evidence-based 5-session school body image intervention for adolescents aged 11-13 years (N=1495, 51.4% male) when delivered by their school teachers is presented. Results showed that intervention effects were analyzed using multilevel models to account for the clustered nature of the data, with multiple imputation employed for missing data, controlling for baseline, and using a significance threshold of p < .01 to account for multiple testing. Compared to control, intervention students reported significant improvements in body esteem at post-intervention (p = .004, Cohen's d = .15), maintained to 2-month (p =
