“…Twenty‐one studies in total have examined these relations, with each finding some evidence of a mediated link between an impulsive trait and alcohol use or problems via alcohol expectancies. This literature consists of 15 cross‐sectional studies (Anderson et al, 2003; Banks & Zapolski, 2017; Coskunpinar & Cyders, 2012; Heath et al, 2019; Kazemi et al, 2014; Marks, 2007; McCarthy, Kroll, & Smith, 2001; McCarthy, Miller, et al, 2001; Mezquita et al, 2015; Morris, 2016; Peterson et al, 2018; Staszkow, 2013; Treloar et al, 2012; Vangsness et al, 2005; Wardell et al, 2015) and six longitudinal studies (Corbin et al, 2011; Fu et al, 2007; Han, 2010; Park et al, 2014; Settles et al, 2010; Wardell et al, 2012). All six of the longitudinal studies found a mediated effect of extraversion or neuroticism on drinking levels through positive expectancies.…”
