“…There is evidence for both selection and socialization of early adolescent AU across longitudinal studies that utilized various methodologies including ecological momentary assessment, social network analysis, and cross-lagged panel designs (Curran, Stice, & Chassin, 1997; Dishion & Skaggs, 2000; Knecht, Burk, Weesie, & Steglich, 2010; Poelen et al, 2007; for a review see Leung, Toumbourou, & Hemphill, 2011). These general conclusions must be tempered in light of the fact that previous work on peer selection and socialization has generally not accounted for the wide range of known correlates of adolescent and peer SU, which include temperament and personality (Chassin, Flora, & King, 2004), psychopathology (King, Iacono, & McGue, 2004; Colder et al, 2013), peer delinquency (Scalco et al, 2014), parental drinking and alcoholism (Alati et al, 2014; Hussong, Curran, & Chassin, 1998), pubertal timing (Costello, Sung, Worthman, & Angold, 2007), amongst others (Chassin, Colder, Hussong, & Sher, in press; Zucker, 2006). These variables are potential confounders for the association between peer and adolescent AU.…”
