A pilot investigation of universal school-based prevention programs for anxiety and depression symptomology in children: A randomized controlled trial.

Abstract

The current study aimed to provide a preliminary evaluation of two universal school-based prevention programs, Emotion Regulation (ER) and Behavioral Activation (BA), by increasing resilience to manage excessive worry, a transdiagnostic feature across anxiety and depression. Primary school children (N = 295; 52.5% female; 8-13 years) from five Australian schools were cluster randomized to an ER, BA or usual class control condition. Outcome measures included resilience, worry, anxiety, and depression symptomology; ER and BA were measured as potential mediators. Participants completed measures at pre- and postprogram, and at 6-month follow-up. Children in the BA condition showed increased resilience at 6 months. Expressive suppression mediated the effects of both programs on worry. The current study aimed to provide a preliminary evaluation of two universal school-based prevention programs, ER and BA, by increasing resilience to manage excessive worry, a transdiagnostic feature across anxiety and depression.
