Richards VL, Rajendran S, Cook RL, Leeman RF, Wang Y, Prins C, Cook C. Identifying Desired Features That Would Be Acceptable and Helpful in a Wrist-Worn Biosensor–Based Alcohol Intervention: Interview Study Among Adults Who Drink Heavily. J Med Internet Res 2023;25:e38713. doi: 10.2196/38713

Researchers identified desired features that could help people reduce their drinking in a wrist-worn biosensor-based alcohol intervention for adults who drink heavily. Wearable alcohol biosensors can passively and continuously measure ethanol excreted through the skin. Participants were at least 40 years old, drank at least twice per week, and were interested in reducing their drinking, and were recruited via an alcohol contingency study, a contact registry, and referrals. In-depth qualitative interviews were conducted on Zoom with 20 participants. Interviews included questions about participants’ thoughts about a wrist-worn biosensor, potential helpfulness to reduce drinking, and what information they would want to receive from the biosensor. Participants reported five major desired feature themes: 1) comfort and look of the biosensor, 2) personalized prompts and feedback, 3) time wearing the biosensor, 4) sharing data with friends, family, and providers, and 5) incorporation of mental health support. In general, participants were open to wearing the biosensor, but were only inclined to engage with the biosensor content if had they were motivation to reduce drinking. Findings also indicated that a mobile app that stores and interprets sensor data for participants to track drinking patterns could be beneficial. Engaging potential end-users to identify desire intervention features can inform and optimize development of interventions that use wrist-worn biosensors to reduce alcohol use.
