An interventional study of Digitally Prompted Parenting and Active Control in Underage Drinking, sponsored by Loyola Marymount University. Completed at 1 site in United States. Open to participants aged 17 Years to 20 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-04-16.

This pilot randomized controlled trial (RCT) will evaluate both the feasibility and efficacy of Digitally Prompted Parenting (DPP), a text-message based parent intervention (tm-PBI) designed to prevent and reduce alcohol use among first-year college students. In this study, parents of incoming first-year students will receive risk-reducing text messages during the first 10 weeks of the Fall semester, which they can forward to their students. The trial uses a longitudinal design to compare drinking outcomes between students whose parents receive the DPP messages and those whose parents receive an established alcohol PBI (the active control condition). The investigators hypothesize that students in the DPP group will report lower levels of alcohol use and fewer alcohol-related consequences after the intervention compared to those in the active control group.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Parents of participating first-year college students in this intervention arm will receive a series of prewritten text messages during the first 10 weeks of college. Parents can personalize these messages before sending them directly to their student, who is the study participant, with the goal of reducing alcohol-related risks.
Behavioral: Digitally Prompted Parenting
Parents of participating first-year college students in this arm of the study will receive access to the Parent Handbook during the summer before matriculation and three booster emails that summarize its key points after matriculation.
Behavioral: Active Control
Parents will receive an email invitation to sign up for Digitally Prompted Parenting, a text message-delivered PBI. Parents set up an account and input information about themselves and their student, which will customize the text messages they receive. Parents will receive at least two text prompts per week for the first 10 weeks of their student's first semester in college. These texts will (1) prompt parents to call their student to discuss the past week and week ahead, and (2) prompt parents to send an alcohol-specific risk reducing text to their student.
Parents will receive an email that explains the Parent Handbook intervention and includes a link to a website where the Handbook is embedded. They will also receive three booster emails summarizing the key points of the intervention. Parents can review both the Parent Handbook and the booster emails at their own pace.
