Motivational models of alcohol consumption have articulated the manner in which positive and negative experiences motivate drinking in unique social contexts (e.g., Cooper, Frone, Russell & Mudar, 1995). Daily process methodology, in which daily events, moods and drinking behaviors are reported daily or multiple times per day, has been used to examine behavioral patterns that are consistent with discrete motivations. We advance the notion that repeated patterns of drinking in various social contexts as a function of positive or negative mood increases can provide evidence of individual-level if-then drinking signatures, which in turn can predict drinking-related outcomes. The purpose of this study was to examine the utility of slopes to predict longer term drinking motivations and alcohol problems, employing a daily process study of non-clinical moderate alcohol drinkers (N=47; 49% women). Participants responded to thrice daily interviews administered via handheld computer for 30 days, followed by a longitudinal telephone survey for 12 months. Participants’ daily mood-drinking relationships were extracted from HLM and employed as predictors of 12-month outcomes in multiple regression analyses. Daily mood-drinking patterns demonstrated significant variability across persons, such that moderate drinkers could be reliably differentiated based on those patterns in terms of distinct drinking-related outcomes. Among the results, negative mood-solitary drinking slopes were associated with lower subsequent coping motives; yet, positive mood-solitary drinking slopes were predictive of higher coping and lower social motives. Conversely, positive mood-social drinking associations were predictive of higher enhancement motives and b-MAST scores. Results are interpreted in light of motivational models of consumption.
