“…In general,
these studies have found that when parents know who their children are with, where
they are, and when they will return (parental monitoring and/or knowledge), children
show fewer externalizing behaviors, associate with fewer delinquent peers, and are
less likely to initiate use of drugs. This pattern of findings has been shown for
initiation of commonly used substances like tobacco, alcohol, and marijuana (Crano, Siegel, Alvaro, Lac, & Hemovich,
2008; Dishion et al, 1995; Dishion & Loeber, 1985; Dorius, Bahr, Hoffmann, & Harmon, 2004; Duncan, Duncan, Biglan, & Ary, 1998; Lac & Crano, 2009; Piko & Kovacs, 2010) as well as for use of other less
commonly used drugs, like ecstasy (Martins, Storr,
Alexandre, & Chilcoat, 2008; Wu,
Liu, & Fan, 2010) and inhalants (Nonnemaker, Crankshaw, Shive, Hussin, & Farrelly, 2011). Although
other parenting behaviors (i.e., hostility, warmth, involvement, and coercive
discipline) have also been shown to predict adolescent substance use (e.g., Cheng & Lo, 2010; Fletcher, Steinberg, & Williams-Wheeler, 2004; Siebenbruner, Englund, Egeland, & Hudson,
2006), generally parental monitoring and knowledge continues to be a
significant predictor above and beyond other parenting behaviors (see Chen, Storr, & Anthony, 2005 for an
exception to this).…”
