An automated recovery monitoring and support system using personal sensing and machine learning may help detect when individuals are at heightened risk. Cellular communication sensing may be a promising approach for passively capturing risk-relevant information about social interactions, particularly when these data are contextualized with participant-specific meaning. We evaluated a machine learning model predicting next-day alcohol lapse among individuals in early recovery from AUD using contextualized cellular communication data and baseline alcohol use, demographic, and psychiatric and personality characteristics. A total of 144 participants (49% male; mean age\u2009=\u200940; 87% non-Hispanic White) with a goal of abstinence provided cellular communication data and alcohol use reports via a 4x daily EMA for up to three months. Models were trained and evaluated using repeated k-fold cross-validation. The best-performing full model used an elastic net algorithm and retained 10 features (median posterior\u00a0auro C\u2009=\u20090.67, 95% Bayesian credible interval (CI; [0.64, 0.71]). A comparison model including only baseline features demonstrated comparable performance (median auROC\u2009=\u20090.69, 95% CI [0.65, 0.72]). Cellular communication features on their own performed poorly, but still above chance performance (median auROC\u2009=\u20090.59, 95% CI [0.55, 0.62]). These findings demonstrate that cellular communication data capture some risk-relevant signal for alcohol lapse but do not provide incremental predictive value beyond baseline measures. Nevertheless, several communication features were retained in the full model with moderately sized coefficients, suggesting that aspects of social communication may still be clinically relevant for understanding lapse risk. However, limitations inherent to cellular communication sensing may outweigh its added utility in lapse prediction models.<\/jats:p>","DOI":"10.1371\/journal.pone.0355396","type":"journal-article","created":{"date-parts":[[2026,8,21]],"date-time":"2026-08-21T17:26:21Z","timestamp":1787333181000},"page":"e0355396","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":0,"title":["Evaluating cellular communication sensing for lapse risk prediction during early recovery from alcohol use disorder: A longitudinal observational study"],"prefix":"10.1371","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0767-7589","authenticated-orcid":true,"given":"Kendra","family":"Wyant","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiachen","family":"Yu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3286-938X","authenticated-orcid":true,"given":"John J.","family":"Curtin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2026,8,21]]},"reference":[{"issue":"13","key":"pone.0355396.ref001","doi-asserted-by":"crossref","first-page":"1689","DOI":"10.1001\/jama.284.13.1689","article-title":"Drug dependence, a chronic medical illness: implications for treatment, insurance, and outcomes evaluation","volume":"284","author":"AT McLellan","year":"2000","journal-title":"JAMA"},{"key":"pone.0355396.ref002","doi-asserted-by":"crossref","first-page":"45","DOI":"10.1151\/ascp074145","article-title":"Managing addiction as a chronic condition","volume":"4","author":"M Dennis","year":"2007","journal-title":"Addict Sci Clin Pract"},{"key":"pone.0355396.ref003","article-title":"Lapse, relapse, and chasing the wagon: post-treatment drinking and recovery","author":"DB Rounsaville","year":"2010","journal-title":"University of Maryland, Baltimore County"},{"key":"pone.0355396.ref004","volume-title":"Relapse Prevention: Maintenance Strategies in the Treatment of Addictive Behaviors","author":"GA Marlatt","year":"1985","edition":"1"},{"key":"pone.0355396.ref005","volume-title":"Relapse Prevention, Second Edition: Maintenance Strategies in the Treatment of Addictive Behaviors","author":"GA Marlatt","year":"2007","edition":"2"},{"key":"pone.0355396.ref006","doi-asserted-by":"crossref","first-page":"177","DOI":"10.1093\/med-psych\/9780190926717.003.0018","article-title":"Reducing the Risk of Relapse.","author":"DC Daley","year":"2019","journal-title":"Managing Substance Use Disorder: Practitioner Guide.
