Influential psychological theories hypothesize that people consume alcohol in response to the experience of both negative and positive emotions. Despite two decades of daily diary and ecological momentary assessment research, it remains unclear whether people consume more alcohol on days they experience higher negative and positive affect in everyday life. In this preregistered meta-analysis, we synthesized the evidence for these daily associations between affect and alcohol use. We included individual participant data from 69 studies (N = 12,394), which used daily and momentary surveys to assess affect and the number of alcoholic drinks consumed. Results indicate that people do not drink more often on days they experience high negative affect, but are more likely to drink and drink heavily on days high in positive affect. People self-reporting a motivational tendency to drink-to-cope and drink-to-enhance were estimated to consume more alcohol, but not to consume more alcohol on days they experience higher negative and positive affect. Results were robust across different operationalizations of affect, study designs, study populations, and individual characteristics. Based on our findings, we collectively propose an agenda for future research to explore open questions surrounding affect and alcohol use.

Influential psychological theories hypothesize that people consume alcohol in response to the experience of both negative and positive emotions. Despite two decades of daily diary and ecological momentary assessment research, it remains unclear whether people consume more alcohol on days they experience higher negative and positive affects in everyday life. In this preregistered meta-analysis, we synthesized the evidence for these daily associations between affect and alcohol use. We included individual participant data from 69 studies (N = 12,394), which used daily and momentary surveys to assess the affect and the number of alcoholic drinks consumed. Results indicate that people are not more likely to drink on days they experience high negative affect but are more likely to drink and drink heavily on days high in positive affect. People self-reporting a motivational tendency to drink-to-cope and drink-to-enhance consumed more alcohol but not on days they experienced higher negative and positive affects. Results were robust across different operationalizations of affect, study designs, study populations, and individual characteristics. These findings challenge the long-held belief that people drink more alcohol following increase in negative affect. Integrating these findings under different theoretical models and limitations of this field of research, we collectively propose an agenda for future research to explore open questions surrounding affect and alcohol use.

Recent studies suggest that solitary (but not social) drinking may confer risk for negative alcohol consequences via beliefs about alcohol’s ability to reduce tension, and explicit motivations to drink to cope with negative mood states. However, because prior studies are largely cross-sectional, it is unclear if tension reduction expectancies and drinking to cope are antecedents or consequences of solitary drinking. The current study aimed to address this gap in the literature using prospective data (3 waves across 12 months) from a sample of moderate to heavy drinking young adults. Data were drawn from a larger investigation of contextual influences on subjective alcohol response. Participants (N = 448) reported on alcohol use in multiple drinking contexts and tension reduction expectancies at baseline (T1), drinking motives at a 6-month follow-up (T2), and past-month negative alcohol consequences at a 12-month follow-up (T3). We examined potential indirect effects of drinking contexts on negative consequences operating through alcohol expectancies and drinking motives. Solitary drinking was indirectly associated with later negative consequences through stronger coping motives, although tension reduction expectancies did not serve as a significant mediator. Social drinking was not directly or indirectly related to later alcohol consequences. Results suggest that solitary drinking contexts confer risk for negative consequences through coping motives, and that these effects are invariant across sex, race, and ethnicity. These findings have important clinical implications as they suggest that targeting solitary drinkers for skills-based coping interventions may reduce risk for a developmental trajectory toward negative alcohol consequences.

Objective: Negative affect (NA) is presumed to be an important trigger for drinking, particularly among coping-motivated drinkers. However, diary studies attempting to predict alcohol use from interactions between state NA and coping motives have proved inconsistent. Craving or momentary desire for alcohol may be a more proximal and robust consequence of NA in coping-motivated drinkers. Method: Data were drawn from an ecological momentary assessment investigation. Frequent drinkers (N = 403) carried electronic diaries for 21 consecutive days, recording their drinking behavior, and rating cravings for alcohol and NA. Results: Outside of active drinking episodes, within-person elevations of momentary NA were associated with increased craving intensity, and this effect was more prominent among drinkers with higher dispositional coping motives. There was no significant interaction between coping motives and momentary NA in predicting the occurrence and amount of same-day alcohol use. Significant conditional indirect effects indicated that NA promoted drinking through increases in craving. These indirect effects were stronger among drinkers reporting higher coping motives. Conclusions: Coping motives and within-person fluctuations in NA interactively predict alcohol craving. NA promotes drinking indirectly via increased craving, particularly among coping-motivated drinkers. Alcohol craving may be a proximal and sensitive response channel for investigating interactions between affective distress and coping motives. Public Health Significance StatementThis study found that increases in the negative mood are associated with increased alcohol craving, particularly among drinkers who report stronger dispositional motives to drink to cope with negative moods. In turn, these increases in craving predicted subsequent alcohol use. The craving may be a useful outcome for investigating the interplay among distal drinking motives, situational instigators, and alcohol use.

Prior research suggests that cannabis expectancies are related to cannabis misuse and problems. Although there are established measures of cannabis expectancies, existing measures have psychometric limitations and/or are lengthy. Existing measures typically have a two-factor structure of positive and negative expectancies, but recent conceptualizations of alcohol expectancies support a valence- (positive vs. negative) and arousal-based (high vs. low arousal) structure. Thus, the present study sought to test a similar structure for cannabis. Cannabis expectancy items underwent 2 preliminary studies, assessing item valance/arousal (n = 233) and relevance to cannabis (n = 124). A final pool of 76 items underwent exploratory factor analysis (n = 303), and remaining items underwent confirmatory factor analysis in a separate sample (n = 469). Lastly, an additional sample (n = 435) examined validity. Results suggested a 3-factor structure (general positive, high arousal negative, low arousal negative) for the 17-item Anticipated Effects of Cannabis Scale (AECS), which was invariant across cannabis use frequency, sex, and race/ethnicity. Positive expectancies were strongly associated with cannabis use, whereas low arousal negative expectancies were protective against cannabis frequency; high arousal negative expectancies were strongly associated with more negative consequences and dependence symptoms. In addition, the proposed interpretation of AECS test scores showed evidence of incremental validity relative to another abbreviated measure. The current study provides initial support for the AECS, a brief, psychometrically sound cannabis expectancies measure. The AECS captures the full range of cannabis effects and may be suited to test discrepancies between cannabis expectancies and subjective response. Additional research is needed to validate its structure and predictive utility.
