Frequent electronic media communication with friends is associated with higher adolescent substance use

Abstract

Objectives This study investigated the unique associations between electronic media communication (EMC) with friends and adolescent substance use (tobacco, alcohol, cannabis), over and beyond the associations of face-to-face (FTF) interactions with friends and the average level of classroom substance use. Methods Drawn from the cross-national 2009/2010 Health Behaviour in School-aged Children (HBSC) study in The Netherlands, 5,642 Dutch adolescents (Mage = 14.29) reported on their substance use, EMC, and FTF interactions. Two-level multilevel analyses (participants nested within classrooms) were run. Results EMC was positively associated with adolescent substance use, though significantly more strongly with alcohol (β = .15, SEβ = .02) than with tobacco (β = .05, SEβ = .02, t(5180) = 3.33, p < .001) or cannabis use (β = .06, SEβ = .02, t(5160) = 2.79, p < .01). Further, EMC strengthened several positive associations of FTF interactions and average classroom substance use with adolescent substance use. Conclusions EMC was uniquely associated with substance use, predominantly with alcohol use. Thus, adolescents’ EMC and other online behaviours should not be left unnoticed in substance use research and prevention programs.
