Digital tools like this are being evaluated because they offer scalable, accessible support for a population that faces elevated rates of emerging mental health and [substance use](https://cedclinic.com/stroke-risk-assessment-substance-use/) challenges. Results from this trial provide evidence-based insight into whether app-based interventions can meaningfully move the needle for this vulnerable group. ### #4 Effectiveness of the Minder Mobile Mental Health and Substance Use Intervention for University Students: Randomized Controlled Trial. **Citation:** Vereschagin Melissa et al. *Effectiveness of the Minder Mobile Mental Health and Substance Use Intervention for University Students: Randomized Controlled Trial.* Journal of medical Internet research. 2024. PMID: 38536225. **Study type:** Randomized Controlled Trial, Journal Article, Research Support, Non-U.S. Gov’t  |  **Topic area:** Anxiety & PTSD  |  **CED Score:** 12 Design: 5 Journal: 0 N: 3 Recency: 1 Pop: 2 Human: 1 Risk: 0 Why This Matters This study evaluates a scalable digital intervention that addresses concurrent mental health and [substance use disorders](https://cedclinic.com/cannabinoid-clinical-trials-mental-disorders-evidence-2/) in university students, a population experiencing peak incidence of these conditions during a critical developmental period. The findings provide evidence for whether mobile app-based interventions can effectively reduce symptom burden and substance use in a high-risk population with documented barriers to traditional in-person mental health services. Positive efficacy data would support integration of such digital tools into university health systems as a cost-effective strategy to augment existing mental health infrastructure and prevent progression to more severe pathology. **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](https://cedclinic.com/cannabis-adolescent-psychiatric-risk-data-study/) 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 Clinical Perspective This randomized controlled trial demonstrates that digital mental health interventions like the Minder app can meaningfully reduce substance use and improve mental health outcomes in university students, a population often underserved by traditional clinical settings. The study’s strengths include rigorous design and relevance to a high-risk developmental period, though we should note that app-based interventions typically show selection bias toward more engaged, motivated users, and outcomes may not generalize equally across socioeconomically diverse or more severely impaired populations. Additionally, the sustainability of benefits beyond the study period and the app’s effectiveness when integrated into real-world campus mental health systems remain important questions. From a clinical standpoint, this research supports recommending evidence-based mobile apps as adjunctive tools for university health centers and primary care providers working with college-age patients, particularly for those with barriers to in-person care or as a bridge intervention while awaiting traditional mental health services.  |   |  Further Reading CED Clinic Blog[Why Cannabis Works](https://cedclinic.com/why-cannabis-works/) Evidence Watch[Cannabis and Heart Health](https://cedclinic.com/cannabis-cardiovascular-health-study/) CED Clinic Blog[Smart Cannabis Dosing](https://cedclinic.com/smart-cannabis-dosing/) [View on PubMed ↗](https://pubmed.ncbi.nlm.nih.gov/38536225/)[Full Text ↗](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11007604/)[DOI ↗](https://doi.org/10.2196/54287) [https://cedclinic.com/contact/](https://cedclinic.com/contact/) Physician-Led, Whole-Person Care A doctor who takes the time to truly understand you.
