An interventional study of Online and Text Message Intervention in Alcohol and Cannabis, sponsored by The University of Texas at Arlington. Not yet recruiting. Open to participants aged 18 Years to 19 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-10-30.
Sponsored by The University of Texas at Arlington · Not applicable, Interventional, and Prevention
Building on promising pilot findings, this study will employ a Hybrid Type 1 Effectiveness-Implementation RCT to evaluate the effectiveness of a novel intervention for first-year college students who abstain from or use alcohol and cannabis lightly, compared to assessment-only control. Aim 1 will finalize the intervention through student feedback to ensure relevance and engagement and Aim 2 will test its impact on abstaining and light alcohol and cannabis use, related consequences, and key cognitive and behavioral outcomes in a two-arm RCT (N = 800) across the first semester and academic year. Aim 3 will assess early implementation outcomes using mixed methods, including focus groups with a Campus Advisory Board, validated survey measures, and intervention analytics, to inform future dissemination and implementation strategies.

Participants in intervention group will receive a web-based personalized feedback intervention and 6 intervention text messages per week (2 text messages per day, 3 days per week) across 12 weeks (first semester of college).
Behavioral: Online and Text Message Intervention
Participants in the intervention condition will receive a brief web-based personalized feedback intervention, which will use participant data reported in the baseline assessment. Text message intervention content will fall into five categories informed by our prior formative work: (1) prototypes, (2) norms, (3) perceived vulnerability, (4) personal goals, and (5) substance-free activities. The intervention is designed to shift the emphasis from reducing heavy use to preventing initiation and escalation by incorporating content that supports students' existing decisions to maintain their abstinence or infrequent alcohol and cannabis use while supporting broader well-being through alternative activities, goal-setting, and peer connections.
Alcohol Initiation
Alcohol initiation for those who abstain at baseline will be calculated as time-to-event from baseline date to the approximate date they first used alcohol.
Time frame: From enrollment to 8 month follow-up
Cannabis Initiation
Cannabis initiation for those who abstain at baseline will be calculated as time-to-event from baseline date to the approximate date they first used cannabis
Time frame: From enrollment to 8 month follow-up
Alcohol Consumption
Alcohol consumption will be assessed using the Daily Drinking Questionnaire, a validated self-report measure assessing the number of standard alcoholic drinks typically consumed on each day of the week, allowing calculation of typical weekly alcohol consumption and drinking frequency.
Time frame: 4 and 8 month follow-up
Cannabis Consumption
Cannabis consumption will be assessed using a measure parallel to the Daily Drinking Questionnaire, and will assess the number of hours high on each day of the week, allowing calculation of typical cannabis use and frequency.
Time frame: 4 and 8 month follow-up
