Objective-We tested whether conduct problems moderate the relation between negative mood and drinking in adolescents as consistent with either a self-medication or a drinking consequences model.
Method-The sample included 75 rising ninth graders who completed a two-stage, multi-method, multi-reporter study. We used experience sampling to assess negative mood and drinking over 21 days and Hierarchical Linear Modeling to test our hypotheses.Results-Counter to predictions, both self-medication and drinking consequence mechanisms were only evident in youth with fewer conduct problems.Conclusions-Findings provide support for the importance of considering multiple mechanisms as underlying the relation between negative mood and drinking as pertaining to sub-populations of vulnerable youth. Implications for prevention and understanding negative mood-drinking relations in adolescents are discussed.The relation between negative mood and drinking continues to cultivate notable interest, despite mounting evidence that the two are only weakly associated (Baker, Piper, McCarthy, Majeskie, & Fiore, 2004). Current approaches to testing this relation may in part explain why stronger effects have not been reported, particularly in adolescents. First, few studies consider alternative mechanisms to self-medication in testing the relation between negative mood and drinking even though such alternatives may be equally powerful in explaining this association (Hussong, Hicks, Levy & Curran, 2001). Second, cross-sectional and long-term prospective research designs used in studies supporting self-medication in adolescents are poorly suited to tests of this mechanism. Whereas studies of adults have used more temporally consistent experience sampling methods (ESM) to examine short-term covariation between mood and drinking (Hussong et al., 2001;Park, Armeli, & Tennen, 2004), no studies have used such methods to test this relation in adolescents. Third, many studies continue to test the main effect of negative mood on adolescent drinking, even though current formulations emphasize individual differences in vulnerability to selfmedication (e.g., Cooper, Frone, Russell & Mudar, 1995;Cooper, Russell, Skinner, Frone & Mudar, 1992;Kushner, Sher, Wood & Wood, 1994). In the current study, we addressed these three limitations by testing whether conduct problems moderate the relation between daily negative mood and adolescent drinking through either a self-medication (in which negative mood leads to drinking) or drinking consequences (in which drinking leads to negative mood) model.
Mechanisms underlying negative mood-drinking relationsEvidence for a weak but consistent prediction of drinking from negative affect (i.e., more stable patterns of negative mood), internalizing symptoms and depression in adolescents is often interpreted as support for a self-medication process in youth (e.g., Halfors, Waller, Bauer, Ford, & Halpern, 2005;Tschann, Adler, Irwin, Millstein et al., 1994). The methods used by these studies test inter-individual diffe...
