Research thus suggests a relationship between adolescent substance use and both parental substance use and parental closeness and monitoring. However, few studies have examined whether parental monitoring or closeness mediates the relationship between parental and adolescent substance use. Two prospective studies have demonstrated that a father's participation in monitoring and discipline mediated the relationship between paternal alcoholism and adolescent alcohol use (King & Chassin, 2004), and one study explicitly tested a mediational model, but did not find a significant relationship between parental problem drinking and parenting behaviors (van der Zwaluw et al., 2008). While these studies examined mediational models of the relationship between parental and adolescent substance use, the authors focused only on parental alcohol use but did not also address the effects of parental drug use.
