Youth sports activity and young people's well-being after a disaster: a trial with the Mastery Approach to Coaching (MAC) in the Philippines.

A total of 293 students completed the questionnaires. The intervention school (n = 51) showed a significant change in self-esteem, with the mean score increasing from 20.2 to 21.1 (p = 0.02). Neither school in the control group showed the significant change. The result showed the feasibility and a positive effect of sports activity with the MAC. However, further investigation should be conducted. Trial registration UMIN Clinical Trials Registry ID: UMIN000033197 on June 30th 2018. Retrospectively registered.
