Objective: Decades of research has found support for the motivational model of alcohol use at the between-person level, yet research on event-level drinking motives is in its nascent stage. Similarly, drinking context has been largely ignored in studies of day-level motives. Therefore, the present study sought to test whether drinking context mediates the relation between affect and motivation on drinking outcomes at both day and person levels. Method: Emerging adults who drank in solitary and social settings (N = 107; 61.2% female) completed 21 days ecological momentary assessments. Affect was assessed during morning/afternoon reports; drinking motives were assessed during afternoon reports; and past-night drinking context, drinking quantity, and negative consequences were assessed during next morning reports. Two-level multilevel structural equation models tested whether within-person and between-person levels of predrinking affect were indirectly associated with negative consequences through predrinking motives, drinking context (social vs. solitary), and drinking quantity. Results: At the day and person levels, positive affect was associated with higher social and enhancement motives. At the day level, positive affect indirectly predicted consequences through social motives, social (vs. solitary) drinking, and drinking quantity, whereas positive affect indirectly predicted consequences through enhancement motives and drinking quantity above and beyond context. At the day and person levels, negative affect was associated with coping motives, but coping was not associated with context, drinking quantity, nor consequences. Conclusions: Findings suggest that positive affect was linked to drinking outcomes through motives (enhancement and social) and contexts (social), whereas negative affect was not. Findings suggest that positively valenced drinking motives may be an important just-in-time intervention target. Public Health Significance Statement: Results suggested that both within-person deviations (and between-person levels) of social drinking motives as well as social drinking (at the within-person level in particular) were mechanisms of risk for alcohol misuse within a motivation framework. However, negative affect and coping motives were not. Findings add to skepticism related to negative reinforcement models of risk for addictive behavior in nonclinical samples and suggest that context and drinking motives may be important event- and person-level mechanisms to target in preventive interventions.

This study reexamined the factor structure of drinking motives using 205 unique items from 18 drinking motives scales with the inclusion of social tension reduction motives, which have been largely neglected in the literature. A new scale was created and compared with the Drinking Motives Questionnaire-Revised (DMQ-R) to predict alcohol use/problems. Young adults (N = 1,049) completed questionnaires assessing drinking motives and alcohol use/problems. A subset (N = 368) of participants completed a 6-month follow-up. Hierarchical factor analyses informed the creation of a four-factor (i.e., coping, social, enhancement, and social tension reduction) scale (i.e., the Young Adult Alcohol Motives Scale [YAAMS]). In general, the YAAMS performed similarly to the DMQ-R in predicting concurrent and prospective alcohol consumption (i.e., typical drinking quantity and frequency) and alcohol problems (i.e., Alcohol Use Disorder Identification Test [AUDIT] and Brief Young Adult Alcohol Consequences Questionnaire [B-YAACQ] scores), but there were some notable differences, including that the novel social tension reduction scale of the YAAMS was particularly relevant in predicting drinking frequency in those with social anxiety. Results suggest that drinking motives can be described by multiple factor structures and predict alcohol-related outcomes. [ABSTRACT FROM AUTHOR]

Pregaming represents a uniquely high-risk drinking event for young adults, and subfacets of impulsivity are robust predictors of alcohol use and related negative outcomes. Further, it is likely that pregame events contain social and physical stimuli that are particularly appealing for impulsive individuals, thus exacerbating risk for negative outcomes. However, no prior studies have investigated the extent to which impulsive personality traits interact with pregame events to confer alcohol-related risk. Thus, the present study examined the extent to which UPPS-P (urgency-perseverance-premeditation-sensation seeking-positive urgency) subfacets of impulsivity interact with the occurrence of pregaming to predict relations between pregaming, drinking quantity, and negative alcohol-related outcomes. College students ( N = 737) completed a modified, online version of the 30-day Timeline Followback in which they reported drinking quantity, negative consequences, and whether they engaged in pregaming on a given day. Results indicated that sensation seeking and a lack of premeditation moderated relations between pregaming and drinking quantity such that those who are higher in sensation seeking and lower in their ability to plan ahead drank more on pregaming days. Sensation seeking and positive urgency moderated relations between pregaming and negative consequences such that those who are higher in positive urgency experience more consequences on pregaming days whereas those who are higher in sensation seeking experience less consequences. Future studies may benefit from more granular assessments of pregame-related risk as subfacets of impulsivity may confer momentary risk. Prevention efforts targeting the reduction of pregaming frequency, particularly among impulsive individuals, may lower overall risk for heavy drinking.
