Between-subjects literature has established that trait-like negative mood predicts coping motives, which predict alcohol-related problems and that trait-like positive mood predicts mood enhancement motives, which then predict alcohol consumption. However, there is considerable within-person variation in drinking motives, and the relationship between mood, motives, and alcohol outcomes must be more closely examined at a daily level. The current study used ecological momentary assessment (EMA) to measure mood, motives, alcohol use, and alcohol consequences in 101 college drinkers over a 15-day period. At the between-subjects level, positive mood predicted enhancement motives, which in turn predicted alcohol consumption and consequences. Negative mood predicted coping motives, which were associated with only alcohol-related consequences. At the withinsubjects level, daily anxious and depressed mood were associated with endorsing coping motives, but coping motives were not associated with alcohol consumption or problems. Positive mood was associated with enhancement motives, which was associated with both daily alcohol consumption and problems. These results corroborate previous findings that enhancement motives are most predictive of outcomes in the college population and highlight the importance of considering within-subject variance in drinking motives. The relationships between mood, motives, and alcohol outcomes differ when examined as between-subjects versus within-subject constructs.
Several theories posit problematic alcohol use develops through mechanisms of positive and negative reinforcement. However, the literature on these mechanisms remains inconsistent. This may be due to a number of issues including a failure to disaggregate negative mood or a failure to account for mood functioning (i.e., stability in mood). Alternatively, there may be differences in typical postdrinking/evening mood on drinking and nondrinking days, however, this has yet to be fully explored. We examined multiple indices of distinct mood states prior to and after typical drinking onset times on drinking and nondrinking days using ecological momentary assessment. College student drinkers ( = 102) carried personal data devices for 15 days. They reported on mood and alcohol use several times per day. Tonic positive mood was higher on drinking days than nondrinking days prior to typical drinking initiation. After typical drinking times, positive mood was higher on drinking days than nondrinking days. Similarly, negative moods (anxiety, stress, anger, and stress instability) indicated a pattern of lower levels relative to both predrinking mood on drinking days, and matched mood time-points on nondrinking days; though, not all of these differences were statistically different. Results suggest positive and negative reinforcing mechanisms may be at play-though the negative reinforcement effects may manifest through subjectively "better" mood on drinking versus nondrinking days.

Spring break (SB) can lead to heavy episodic drinking and increased alcohol-related risks. This may be especially relevant for women. The current study utilized deviance regulation theory to increase the use of protective behavioral strategies (PBSs) among female college students on SB. Female college students going on SB (n = 62) completed a screening, a pre-SB intervention (where they were randomly assigned to receive either a positively or negatively framed message about individuals who do or do not use PBS), and a post-SB assessment that provided alcohol and PBS use data for each day of SB (n = 620 person-days). Data were analyzed using a multilevel structural equation model. In the negative frame, SB PBS use was higher among those who perceived SB PBS norms to be more common on SB relative to non-SB. In the positive frame, SB PBS use was higher among those who perceived SB PBS norms to be less common on SB relative to non-SB. These associations did not result in lower alcohol consumption, but did result in a lower likelihood of experiencing alcohol-related problems during SB. These results suggest that a brief online intervention, that utilizes targeted messages based on normative perceptions of SB PBS use, could be an effective strategy for reducing alcohol-related consequences among college student women during SB.

OBJECTIVE:
Normative feedback remains an effective approach to reducing alcohol use among college students. However, this approach is difficult to extend to protective behavioral strategies (PBS), which are proximal to alcohol-related problems. Deviance Regulation Theory (DRT) is a social psychology theory that posits individuals choose engage in behaviors to standout out in positive ways or avoid standing out in negative ways. The current study tests a DRT-based randomized control trial.
METHOD:
College student drinkers (n = 130) reported on PBS norm frequency, alcohol use, and PBS use. They were then randomly assigned to receive a positive message about PBS users, a negative message about non-PBS users, or a control. They reported on weekly PBS use, alcohol use, and alcohol problems for 10 weeks.
RESULTS:
Consistent with DRT, there were immediate post-intervention effects on PBS use for individuals who believed PBS was uncommon and who also received a positive message. This remained stable across time. There was significant growth in PBS use among individuals who received a negative message and who believed PBS use was common. The intervention was not directly associated with alcohol use or problems. However, PBS use was associated with average alcohol use and lower weekly and global alcohol problems.
CONCLUSIONS:
This study shows that a DRT intervention may increase PBS use. This may translate into lower alcohol use and fewer alcohol-related problems. The results also identify conditions under which positive and negative messages are indicated.
