Clinical Takeaway
A randomized controlled trial tested the Minder mobile app, co-developed with university students, to address mental health and substance use 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 care. Results from this trial provide evidence on whether app-based interventions can meaningfully improve outcomes in this population.

This randomized controlled trial evaluates a scalable digital intervention for mental health and substance use disorders in a high-risk population during a critical developmental window, addressing a documented gap in accessible mental health support for university students. The study’s focus on a student-codeveloped app provides clinically relevant evidence on whether digital interventions can effectively reduce substance use and mental health symptoms in young adults, populations that traditionally underutilize conventional mental health services. Positive outcomes would support the integration of mobile-based interventions into university health systems and broader mental health care pathways as a cost-effective, accessible treatment option.
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
🧠 The Minder app study addresses a genuine clinical need, as university students face real barriers to accessing traditional mental health and substance use services during a critical developmental window. However, several important limitations warrant cautious interpretation: the study does not clarify whether Minder replaces standard care or supplements it, participant selection bias may favor those already motivated to engage with digital tools, and the sustainability of behavior change beyond the study period remains unknown. Additionally, we lack clarity on which student populations benefit most (for instance, those with mild symptoms versus those requiring intensive intervention) and whether the app’s effectiveness generalizes beyond the university setting where it was developed. From a clinical standpoint, while digital interventions like Minder show promise for improving access and reducing stigma around help-seeking, they should currently be integrated into a comprehensive care approach rather than viewed as a standalone solution for students with moderate to severe mental health or substance use concerns.
