“…Parental nurturance has been identified as a salient influence on early adolescent alcohol use, while deficits in parental support have been linked both cross-sectionally and prospectively to a number of problem behaviors in adolescents, including adolescent substance abuse (Barnes, Reifman, Farrell, & Dintcheff, 2000;Korhonena, Huizinkc, Dick, Pulkkinene, Rosca, & Kaprio, 2008;Simons-Morton, 2007). Parental monitoring has been shown to be a protective factor against several problems in adolescence both cross-sectionally and longitudinally, with higher levels of parental monitoring being associated with lower levels of alcohol use and reduced odds for onset of heavy drinking and other drug use (Barnes et al, 2000;Lochman, Wells, & Murray, 2007;Weiss, Liu, Sussman, Unger, Cen, Chou, et al, 2006). Explicit parental disapproval of substance use has been associated with decreased alcohol and drug involvement in early adolescence in several studies (Barnes & Welte, 1986;Dielman, Butchart, & Shope, 1993;Hyatt & Collins, 2000).…”
