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 Minder offer a scalable, accessible option for reaching students who may not seek traditional clinical care. Clinicians working with young adults should be aware that app-based interventions are being rigorously evaluated as legitimate adjuncts to standard mental health and substance use support.

This randomized controlled trial provides evidence for the efficacy of a scalable digital intervention targeting the critical transition period of university attendance, when mental health and substance use disorders frequently emerge. The study’s evaluation of Minder, a student-codeveloped app, demonstrates the clinical utility of mobile-based interventions that can extend mental health support beyond traditional in-person services to a population with significant barriers to care access. These findings support the integration of evidence-based digital tools into university health systems to improve early intervention and outcomes for students experiencing mental health and substance use challenges.
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
🧠 While this randomized controlled trial of the Minder app demonstrates promise for scalable digital mental health and substance use support in university populations, clinicians should note several important caveats before recommending it widely. The study’s reliance on self-reported outcomes, potential selection bias toward digitally engaged students, and lack of long-term follow-up data limit our ability to assess sustained clinical benefit or identify which patient subgroups might benefit most. Additionally, the app’s effectiveness may vary considerably depending on baseline severity of symptoms, concurrent use of other treatments, and the student’s actual engagement and adherence patterns in real-world settings outside the trial protocol. From a practical standpoint, the Minder app appears reasonable to suggest as a complementary tool for university health centers serving students with mild to moderate mental health or substance use concerns, particularly as part of a stepped-care approach, but should not be positioned as a standalone replacement for in-person assessment or treatment of more significant conditions.
