Clinical Takeaway
A randomized controlled trial tested the Minder mobile app, co-developed with university students, to address mental health and substance use concerns during the high-risk college transition period. Digital tools like this are being studied because they can reach large numbers of students who may not seek traditional clinical care. Results from this trial provide evidence-based guidance on whether app-based interventions can meaningfully improve outcomes in this population.

This randomized controlled trial evaluates a scalable digital intervention specifically designed for a high-risk population experiencing coincident mental health and substance use issues during a critical developmental period. The study’s findings on app-based intervention efficacy have direct implications for university health systems seeking to address the documented surge in student mental health and substance use disorders through accessible, technology-enabled treatment options. Demonstration of effectiveness could support implementation of evidence-based digital tools that extend care reach beyond traditional campus mental health services constrained by resource limitations.
Abstract: BACKGROUND: University attendance represents a transition period for students that often coincides with the emergence of mental health and substance use challenges. Digital interventions have been identified as a promising means of supporting students due to their scalability, adaptability, and acceptability. Minder is a mental health and substance use mobile app that was codeveloped with university students. OBJECTIVE: This study aims to examine the effectiveness of the Minder mobile app in improving mental health and substance use outcomes in a general population of university students. METHODS: A 2-arm, parallel-assignment, single-blinded, 30-day randomized controlled trial was used to evaluate Minder using intention-to-treat analysis. In total, 1489 participants were recruited and randomly assigned to the intervention (n=743, 49.9%) or waitlist control (n=746, 50.1%) condition. The Minder app delivers evidence-based content through an automated chatbot and connects participants with services and university social groups. Participants are also assigned a trained peer coach to support them. The primary outcomes were measured through in-app self-assessments and included changes in general anxiety symptomology, depressive symptomology, and alcohol consumption risk measured using the 7-item General Anxiety Disorder scale, 9-item Patient Health Questionnaire, and US Alcohol Use Disorders Identification Test-Consumption Scale, respectively, from baseline to 30-day follow-up. Secondary outcomes included measures related to changes in the frequency of substance use (cannabis, alcohol, opioids, and nonmedical stimulants) and mental well-being. Generalized linear mixed-effects models were used to examine each outcome. RESULTS: In total, 79.3% (589/743) of participants in the intervention group and 83% (619/746) of participants in the control group completed the follow-up survey. The intervention group had significantly greater average reductions in anxiety symptoms measure
🧠 This randomized controlled trial of a student-codeveloped mobile app addresses a genuine clinical need, as the university transition period does coincide with emerging mental health and substance use vulnerability. However, the abstract provided is incomplete, limiting our ability to assess critical outcomes, effect sizes, and whether benefits extended to cannabis use specifically or only other substances. Mobile health interventions show promise for engagement and reach, yet questions remain about durability of behavioral change after app use ends, potential selection bias toward tech-savvy students, and whether digital support adequately addresses students requiring more intensive treatment. For clinicians advising college-age patients, this work suggests apps may serve as useful adjuncts to standard care and screening, but should not substitute for direct assessment of mental health and substance use trajectories, particularly in students with established cannabis dependence or comorbid psychiatric conditions requiring close monitoring.
