Profiles of transdermal alcohol concentration and their prediction of negative and positive alcohol-related consequences in young adults’ natural settings.

Transdermal alcohol concentration (TAC) sensors provide a multidimensional characterization of drinking events that self-reports cannot. These profiles may differ in their associated day-level alcohol-related consequences, but no research has tested this. We address this using multilevel latent profile analysis. Two hundred twenty-two young adults who regularly engage in heavy drinking ( High-fast (incident rate ratio [IRR Compared to little-to-no-drinking days, TAC profiles indicative of drinking (high-fast, moderate-fast, and low-slow) contained more negative and positive consequences. However, the odds of experiencing
