Stand Down-Think Before You Drink: An RCT of a Mobile App for Hazardous Drinking With Peer Phone Support

One in four Veterans presenting to VA primary care screen positive for hazardous drinking. However, due to barriers such as Veterans' stigma about seeking alcohol use treatment and challenges with traveling to VA, most of these Veterans do not receive any alcohol-related care. Mobile applications (apps) are an innovative means of expanding access to alcohol use treatment. The evidence for mobile apps, such as "Step Away", to improve drinking outcomes is emerging. Nevertheless, poor patient engagement remains the Achilles' heel of these apps. Peer Specialists ("Peers") can facilitate Veterans' engagement with mobile apps intended for self-management of hazardous drinking by helping to orient patients to these apps and by providing technical support and accountability. In a VA HSR\&D pilot study, the investigators created a Veteran version of the Step Away app ("Stand Down: Think Before You Drink") and conducted an open trial in which Veterans with hazardous drinking used the app while receiving Peer phone support. The intervention ("Peer-Supported \[PS\]-Stand Down") was highly acceptable to patients, and patients reported significant improvements in drinking outcomes. These data provide a strong foundation for a larger pragmatic trial to test the effectiveness of the Stand Down app and PS-Stand Down to reduce hazardous drinking among Veterans seen in primary care, relative to the current standard of care that these patients receive. In the current study, the investigators will evaluate whether the Stand Down app reduces drinking among Veteran primary care patients who engage in hazardous drinking, and for whom PS-Stand Down is more effective than the app alone. Aim 1: Test whether Stand Down (vs. Usual Care; UC) and PS-Stand Down (vs. UC and vs. app only) predicts better drinking outcomes, and test mediators of these effects. Aim 2: Test for differences in satisfaction with care across conditions, and conduct qualitative interviews with patients and PACT staff to understand potential barriers/facilitators to implementing PS-Stand Down in primary care. Aim 3: Explore baseline moderators to elucidate for whom PS-Stand Down (vs. app only) is most beneficial. In a 3-group RCT at the Palo Alto and Syracuse VAs, 274 Veteran primary patients who screen positive for hazardous drinking, received a brief intervention following a positive screen, and are not currently in alcohol use treatment will complete a baseline interview, be randomized to either (i) UC, (ii) UC plus Stand Down, or (iii) UC plus PS-Stand Down (four phone sessions with a Peer over 8 weeks to enhance app engagement), and be re-interviewed at 8, 20, and 32 weeks. For Aim 2, the CFIR framework will guide key informant interviews with 12 patients and 12 PACT providers from each site.
