Comparison of digital behavioral interventions to prevent alcohol misuse among adolescents ages 12 to 19: A...

Prevention of alcohol use and misuse among adolescents is a public health priority. A health care visit provides an opportunity for screening for alcohol use and delivery of early interventions. Digital intervention delivery may reduce barriers to implementation in these settings. Herein, we describe the protocol from an ongoing comparative effectiveness study testing digital interventions to prevent escalation of alcohol use among adolescents (ages 12-19) connected to pediatric healthcare. Adolescents screening positive for past-year alcohol use are eligible to participate. Enrolled participants complete a baseline survey and are randomly assigned [stratified by sex and age group (12-14; 15-17; 18-19)] to an interactive, ∼45-min computerized brief intervention (CBI) alone or combined with 8 weeks of text messages. Outcomes are assessed at 3-, 6-, 9-, and 12-months post-baseline. Primary outcomes include past 3-month alcohol consumption. Secondary outcomes include alcohol and drug consequences, illicit and prescription drug misuse, and depression symptoms. In parallel, caregivers are also invited to participate, which involves referral to download the app "Talk. They Hear You." and completing surveys at baseline, 3-, 6-, 9- and 12- months to report their use of the app. A novel aspect of this study is that we partnered with adolescents, caregivers, and health care staff and clinicians throughout the study to enhance relevance, effectiveness, and potential for future dissemination. This study will provide critical data to inform implementation of digital interventions for pediatric patients with the potential to prevent negative health outcomes and promote adolescent well-being.
