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 high-risk transition period of higher education. Digital tools like Minder are designed to be scalable and accessible alternatives or supplements to traditional campus mental health services. Results from this trial provide evidence-based guidance on whether app-based interventions can produce meaningful improvements in student mental health and substance use outcomes.

This randomized controlled trial provides evidence on whether a student-designed mobile app can effectively reduce mental health and substance use problems during a critical developmental period when these conditions typically emerge. The findings are clinically significant because they demonstrate whether digital interventions can achieve meaningful outcomes at scale, potentially offering a cost-effective tool to address the growing mental health crisis on university campuses. If effective, the Minder app could inform implementation of digital mental health screening and intervention protocols in campus health systems and student wellness programs.
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 examining the Minder app for mental health and substance use in university students addresses a genuine clinical need, given the high prevalence of these co-occurring conditions during the college transition. The digital intervention approach offers practical advantages for reaching this population, though we should note that efficacy in a controlled research setting may not fully translate to real-world adherence and engagement, particularly among students with more severe presentations who might require in-person care. The codevelopment with students strengthens the design’s relevance, but the abstract provided appears incomplete, limiting our ability to assess effect sizes, primary outcomes, and whether specific subgroups benefited differentially. Clinicians should view promising digital tools like this as potentially valuable adjuncts to standard care rather than replacements, especially for mild-to-moderate symptoms, while maintaining vigilance for students who need traditional clinical assessment and referral. When counseling university health centers or students on mental health resources, evidence-based mobile interventions can reasonably be recommended as accessible first-line options
