Therefore, this study evaluates person-specific and pooled prediction models for binge eating (BE), alcohol use, and binge drinking (BD) in daily life, and identifies the most important predictors.<\/jats:p><\/jats:sec><jats:sec id=\"S0033291724000862_sec_a2\" sec-type=\"methods\"><jats:title>Methods<\/jats:title><jats:p>A total of 120 patients (BN: 50; AUD: 51; BN\/AUD: 19) participated in an experience sampling study, where over a period of 12 months they reported on their eating and drinking behaviors as well as on several other emotional, behavioral, and contextual factors in daily life. The study had a burst-measurement design, where assessments occurred eight times a day on Thursdays, Fridays, and Saturdays in seven bursts of three weeks. Afterwards, person-specific and pooled models were fit with elastic net regularized regression and evaluated with cross-validation. From these models, the variables with the 10% highest estimates were identified.<\/jats:p><\/jats:sec><jats:sec id=\"S0033291724000862_sec_a3\" sec-type=\"results\"><jats:title>Results<\/jats:title><jats:p>The person-specific models had a median AUC of 0.61, 0.80, and 0.85 for BE, alcohol use, and BD respectively, while the pooled models had a median AUC of 0.70, 0.90, and 0.93. The most important predictors across the behaviors were craving and time of day.
