Summary

Currently, one in five rangatahi (young people) in Aotearoa report difficulty accessing support for their mental health concerns. This treatment gap has prompted academics and clinicians to consider whether online and/or school-based interventions can increase access to evidence-based mental health care. This research is a randomised controlled trial to evaluate the effectiveness of Project SOLVE, an online problem-solving intervention, compared to Project Success, an activity that teaches young people study skills. Underdeveloped problem-solving skills have been associated with varying presentations of mental distress, including depression, hopelessness, and suicidal ideation. This association has meant problem solving is often featured as a core component of therapeutic interventions, and strengthening problem solving skills has been shown to improve clinical outcomes in youth who experience mental health concerns. For these reasons, the investigators hope that Project SOLVE will support the development of problem solving in rangatahi in Aotearoa and have a positive effect on their proximal and longitudinal mental health outcomes.

Interventions

Type	Name	Description
BEHAVIORAL	Project SOLVE	Project SOLVE is a 30-minute self-guided online activity that includes an introduction to problem solving and which types of problems might be most appropriate for this skill; a description of how the brain facilitates problem solving; vignettes demonstrating how older adolescents have solved their problems; scientific evidence that problem solving can work; practice exercises; and activities to encourage the use of problem solving in daily life. The intervention teaches students how to solve problems via the "SOLVE" framework (i.e., Saying what the problem is; One goal to aim for; Listing some solutions; Voting for the best solution; Exploring what works).
BEHAVIORAL	Project Success	Project Success is comparable to Project SOLVE in format and length (i.e., a 30 minute online, self-guided intervention) and teaches young people three strategies to reach their academic goals: how to take effective notes, how to break big assignments down into smaller tasks, and how to ask trusted others for help.
