“…Furthermore, both extraversion and a combination of impulsivity and sensation seeking were found to moderate the degree of peer association on drug use (Knyazev, Slobodskaya, Kharchenko, & Wilson, 2004). The link between peer association and adolescent substance use was found to be moderated by several other individual characteristics such as expectations about one's future (e.g., academic, professional and general optimism about the future; MacNeil, Kaufman, Dressler, & LeCroy, 1999), refusal assertiveness (e.g., the ability to refuse assertively someone's proposition; Epstein & Botvin, 2002), drug and alcohol refusal efficacy (Clark, Belgrave & Abell, 2012) and behavioral regulation (Wills, Pokhrel, Morehouse, & Fenster, 2011). Furthermore, identity commitment (including information on: future occupation, religion, politics, relationships, family, friends, dating partners, sex roles, and personal values; Dumas, Ellis & Wolfe, 2012), and adolescents' propensity to fantasize while listening to music (e.g., imagining that they were playing the music, or used the music to dream about being in a different place; Miranda, Gaudreau, Morizot, & Fallu, 2012) were two other factors which moderated the link between peer association and adolescent substance use.…”
