Clinical Takeaway
A randomized controlled trial tested the Minder mobile app, co-developed with university students, to address mental health and substance use challenges during the college transition period. Digital tools like this are being studied because they can reach large numbers of students in a scalable, accessible format. Results from this trial provide evidence-based data on whether app-based interventions can meaningfully improve mental health and reduce substance use in this high-risk population.

This study evaluates a scalable digital intervention for mental health and substance use disorders in a high-risk population during a critical developmental period when these conditions commonly emerge. The findings provide evidence regarding whether mobile app-based interventions can effectively address comorbid mental health and substance use in university students, informing clinical implementation strategies for preventive care in this population. Results demonstrating efficacy would support the integration of digital therapeutics into campus health systems as an accessible adjunct to traditional clinical services.
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 examines a student-codeveloped mobile app for mental health and substance use support during the vulnerable university transition period, a time when many young adults first encounter or escalate problematic use patterns. While the participatory design approach and scalability of digital interventions are appealing, clinicians should recognize that app-based interventions typically show modest effect sizes, engagement often drops significantly after initial enrollment, and self-selected study participants may not represent the students most in need of support. The study’s generalizability may also be limited by university setting specifics, cultural factors affecting app adoption, and the lack of detail regarding how cannabis use specifically was measured or addressed compared to other substances. For clinical practice, while recommending evidence-based digital tools can complement traditional care and reach students reluctant to seek in-person services, providers should view mobile apps as adjunctive rather than primary interventions and maintain direct contact to assess whether students are actually using these tools and benefiting from them.
