A clustered-randomized controlled trial of a self-reflection resilience-strengthening intervention and novel mediators.

This study tests the efficacy of a unique resilience-strengthening intervention using a clustered-randomized controlled trial. It was hypothesized that the training, which encourages adaptive self-reflection on stressor events and the effectiveness of coping strategies and resources, would exert a positive effect on mental health outcomes via increased reflection and decreased brooding.

Platoons of Cadets were randomly allocated to either Self-Reflection Resilience Training (SRT;
