Although frequently hypothesized, the evidence for associations between affect and marijuana use in everyday life remains ambiguous. Inconsistent findings across existing work may be due, in part, to differences in study design and analytic decisions, such as study inclusion criteria, the operationalization of affect, or the timing of affect assessment. We used specification curves to assess the robustness of the evidence for affect predicting same-day marijuana use and marijuana use predicting next-day affect across several hundred models that varied in terms of decisions that reflect those typical in this literature (e.g., whether to average affect prior to marijuana use or select the affect report closest in time to marijuana use). We fitted these curves to data from two ecological momentary assessment studies of regular marijuana and/or alcohol using college students (N = 287). Results provided robust evidence that marijuana use was slightly less likely following experiences of negative affect and slightly more likely following positive affect. Specification curves suggested that differences in previous findings are most likely a function of the specific emotion items used to represent affect rather than differences in inclusion criteria, the temporal assessment and modeling of affect, or the covariates added to the model. There was little evidence for an association between marijuana use and next-day affect. Overall, our findings provide evidence against the predictions made by affect reinforcement models in college students and suggest that future research should model the associations of marijuana use with discrete emotional states rather than general negative and positive affect.

Emotion regulation (ER) is an important factor in resilience and overall well-being throughout development, and youth report increased variation in emotion and capacity for regulation across adolescence and early adulthood. Specific emotions may be associated with the use of different ER strategies, but much evidence exclusively collapses across negative and positive affect or may not reflect the daily experience of emotion and emotion regulation. The present study examined associations between the experience of unique positive and negative emotions and the use of common ER strategies in adolescence and early adulthood during daily life using ecological momentary assessment (EMA). The sample included 184 high school and college students (55% female, M age = 17.88, SD = 1.25) who completed EMA surveys three times daily for 10 days (89% compliance). Participants reported on their recent emotional states and which of eight ER strategies they had used. Multilevel logistic regressions tested emotions as predictors of ER strategies, separately for each emotion-ER strategy combination across 96 total models, using the Benjamini-Hochberg procedure to control the false discovery rate. Individuals had higher odds of engaging in maladaptive ER strategies, particularly suppression or rumination, when reporting most types of negative emotions-with the largest associations among unhappiness and anger. Conversely, positive emotions were generally linked to reported use of no ER strategies, though happiness and engagement were related to higher odds of problem-solving, while calm was related to less use of nearly all strategies. Specific emotion-strategy combinations may have implications for clinical targets. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

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 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 affect. 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 increases 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., Competing Interests: Competing interests: Authors declare that they have no competing interests.
