BACKGROUND: Technology use may be one strategy to promote mental health and wellbeing among young adults in post-secondary education settings experiencing increasing distress and mental health difficulties. The JoyPop™ app is mobile mental health tool with a growing evidence base. The objectives of this research are to (1) evaluate the effectiveness of the JoyPop™ app in improving emotion regulation skills (primary outcome), as well as mental health, wellbeing, and resilience (secondary outcomes); (2) evaluate sustained app use once users are no longer reminded and determine whether sustained use is associated with maintained improvements in primary and secondary outcomes; (3) determine whether those in the intervention condition have lower mental health service usage and associated costs compared to those in the control condition; and (4) assess users' perspectives on the quality of the JoyPop™ app. METHODS: A pragmatic, parallel arm randomized controlled trial will be used. Participants will be randomly allocated using stratified block randomization in a 1:1 ratio to the intervention (JoyPop™) or control (no intervention) condition. Participants allocated to the intervention condition will be asked to use the JoyPop™ app at least twice daily for 4 weeks. Participants will complete outcome measures at four assessment time-points (first [baseline], second [after 2 weeks], third [after 4 weeks], fourth [after 8 weeks; follow-up]). Participants in the control condition will be offered access to the app after the fourth assessment time-point. DISCUSSION: Results will determine the effectiveness of the JoyPop™ app for promoting mental health and wellbeing among post-secondary students. If effective, this may encourage more widespread adoption of the JoyPop™ app by post-secondary institutions as part of their response to student mental health needs.
