“…Conversely, mediators of the relationship between exposure to alcohol social media content and alcohol use were less varied with most studies finding injunctive norms (Geusens & Beullens, 2016; Nesi et al, 2017; Vranken et al, 2020) and descriptive norms (Alhabash, Kanver, et al, 2021, Boyle et al, 2016; Brunelle & Hopley, 2017; Davis et al, 2019; LaBrie, Trager, et al, 2021; Roberson et al, 2018; Vranken et al, 2020), to significantly explain this relationship both cross-sectionally and over time (9–12 months later). Other significant mediators included attitudes toward alcohol use (Geusens & Beullens, 2016; Roberson et al, 2018), enhancement drinking motives (6 months later, Boyle et al, 2016), college alcohol beliefs (6 months later, Boyle et al, 2016), and drinking identity (Geusens & Beullens, 2021).…”
