An online peer support program to improve mental health among university students: A randomized controlled trial.

Despite recent calls for more peer support initiatives aimed at promoting mental health in postsecondary institutions, those initiatives remain scarce. In this study, a multisite randomized controlled trial was designed to assess the effect of an online peer support intervention based on acceptance and commitment therapy using mental health and school indicators. Undergraduate students were recruited in three Canadian universities and randomly assigned to an intervention ( = 54) or a wait-list control group ( = 53).
