Stevely AK, holmes J, Petra M, et al. - Researchers performed a mapping review aimed at identifying and characterizing the theoretical approaches to conceptualizing drinking occasions, study designs, predictors, and outcome measures that are used in existing research, while recognizing dominant approaches, research gaps, and areas for further synthesis. Using quantitative event-level methods, eligible papers examined adults’ drinking occasions and acknowledged one or more contextual characteristics (eg venue, timing, or company) and at least one event-level consumption or acute alcohol-related harm outcome. Two hundred seventy-eight eligible papers were identified (from 1975 to 2019), mostly published after 2010 (n =181; 65.1%). These papers mainly focused on students and consumption outcomes and had considered, mostly, a limited range of contextual characteristics. Researches conducted in the United States were mostly reported in these papers (n = 170; 61.2%). They identified only 53 (19.1%) papers that assessed three or more occasion characteristics; most of the papers utilized methods that accept occasion characteristics do not vary during an occasion (n = 189; 68.0%). Consideration was given to consumption as most common outcome type (n = 224; 80.6%) and there were only a few papers that studied specific acute harm outcomes such as unprotected sex (n = 24; 8.6%), drink driving (n = 14; 5.0%) or sexual violence (n = 9; 3.2%).
