“…Specifically, self‐reports of alcohol consumption can be impacted by self‐presentational concerns and alcohol‐related cognitive disruptions (Cherpitel et al, 2018; Ernhart et al, 1988; White, 2003), improperly used breathalyzers can produce readings biased by mouth alcohol (Caddy et al, 1978; Gullberg, 1992), and blood draws are impractical for use in the field. In light of their ability to objectively and unobtrusively assess consumption patterns in naturalistic environments, transdermal sensors have the potential to help users gain insight into their drinking patterns and by extension minimize alcohol‐related morbidity and mortality (Fairbairn & Kang, 2021; Fridberg et al, 2022; Luczak et al, 2018; Piasecki, 2019).…”

“…The science of wearable transdermal sensors continues to advance, offering sleeker and less intrusive sensors providing drinking detection and tracking in near real time (Ash et al, 2022;Fairbairn & Bosch, 2021;Fridberg et al, 2022;Wang et al, 2019Wang et al, , 2021. As a result, research professionals and consumers alike are likely to increase the adoption of wearable TAC sensor technology, creating an urgent need to establish the potential of TAC data as a means of documenting risk and protective processes in natural settings (Fridberg et al, 2022;Piasecki, 2019;Russell et al, 2022). The results of the current article offer the first evidence to our knowledge supporting the utility of TAC features in detecting individual differences in drinking behaviors such as PBS and partially explaining differences in consequence risk associated with the frequency of PBS use.…”

Objective: Test whether frequent protective behavioral strategies (PBS) users report (a) fewer alcohol-related consequences and (b) less risky alcohol intoxication dynamics (measured via transdermal alcohol concentration [TAC] sensor "features") in daily life. Method: Two hundred twenty-two frequently heavy-drinking young adults (M age = 22.3 years) wore TAC sensors for 6 consecutive days. TAC features peak (maximum TAC), rise rate (speed of TAC increase), and area under the curve (AUC) were derived for each day. Negative alcohol-related consequences were measured in the morning after each self-reported drinking day. Past-year PBS use was measured at baseline. Results: Young adults reporting more frequent baseline PBS use showed (a) fewer alcohol-related consequences and (b) lower intoxication dynamics on average (less AUC, lower peaks, and slower rise rates). Limiting/stopping and manner of drinking PBS showed the same pattern of findings as the total score. Serious harm reduction PBS predicted fewer negative alcohol-related consequences, but not TAC features. Multilevel path models showed that TAC features peak and rise rate partially explained associations between PBS (total, limiting/stopping, and manner of drinking) and consequences. Independent contributions of PBS subscales were small and nonsignificant, suggesting that total PBS use was a more important predictor of risk/protection than the specific types of PBS used. Conclusions: Young adults using more total PBS may experience fewer alcohol-related consequences during real-world drinking episodes in part through less risky intoxication dynamics (TAC features). Future research measuring PBS at the daily level is needed to formally test TAC features as day-level mechanisms of protection from acute alcohol-related consequences. Public Health Significance StatementThis study shows that among young adults who report frequent heavy drinking, those who report more versus less frequently using protective behavioral strategies (PBS) show lower intoxication peaks and slower intoxication increases during drinking events, as well as fewer negative alcohol-related consequences following drinking events. Differences in alcohol intoxication dynamics as PBS frequency increased explained 10%-21% of the PBS association with alcohol-related consequences. These results support further investigation of PBS at the daily level that tests whether intoxication dynamics provide a mechanism through which PBS reduce consequences in natural settings.

“…Just-in-time adaptive interventions (JITAIs) are designed to provide the right support at the right time [43]. There was much discussion about how the continuous monitoring provided by the Skyn biosensor could lead to real-time intervention, indicating that it may fit well into a JITAI [44]. In this context, individuals could help to design their own intervention features, including TAC limits at which they receive alerts and whom their data are shared with (eg, should a counselor also receive the alert?).…”

Background Alcohol misuse is highly prevalent in the United States and results in a huge financial and public health burden. Current alcohol reduction treatments are underused, and there is a critical need for innovation in the field. Transdermal alcohol biosensors measure alcohol use passively and continuously and may be helpful tools in alcohol interventions. To date, however, alcohol biosensors have not been widely used to directly intervene on alcohol use. There is a new wrist-worn biosensor that could be used to help people reduce their drinking, although it is unclear how best to incorporate such a device into an alcohol intervention. Objective We aimed to identify desired features that would be acceptable and helpful in a wrist-worn biosensor–based alcohol intervention for adults who drink heavily. Methods Participants were recruited through an alcohol contingency management study, a contact registry, and participant referral. To qualify, participants had to be aged at least 40 years, report drinking at least twice per week, and indicate interest in reducing their drinking. We conducted a semistructured interview with each participant via Zoom (Zoom Video Communications, Inc). The interview guide addressed general thoughts on the wrist-worn biosensor, how participants thought a wrist-worn biosensor could be used to help people quit or reduce drinking, types of information that participants would want to receive from the biosensor, how they would want to receive this information, and how they thought this information could be used to change their behavior. Interviews were transcribed verbatim and analyzed using thematic analysis. Results The sample comprised 20 adults (mean age 55.1, SD 6.1 years; 11/20, 55%, women; and 17/20, 85%, Black). Of the 20 participants, 9 (45%) had previous experience with the Secure Continuous Remote Alcohol Monitor continuous alcohol monitoring ankle biosensor from participating in an alcohol contingency management study. The desirable features could be grouped into 5 main themes: features that would influence willingness to use the biosensor (it should look attractive and be both comfortable to wear and accessible), personalized messaging (personalized biosensor-based prompts and feedback could be helpful), preference for time wearing the biosensor (for some, just wearing the biosensor could have an intervention effect), sharing data with others (this was appealing to many but not to all), and mental health support (many felt that mental health support could be incorporated into the biosensor). Conclusions Five main themes that would maximize interest in using a wrist-worn biosensor for alcohol intervention were identified. Taken together, the identified themes could inform the development of a just-in-time adaptive intervention that uses a wrist-worn biosensor to help adults who drink heavily reduce their alcohol use.
