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.

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.

Ecological stress during adolescent development may increase the sensitivity to negative emotional processes that can contribute to the onset and progression of internalizing behaviors during preadolescence. Although a small number of studies have considered the link among the complex relations in ecological stress, amygdala reactivity and internalizing symptoms in childhood and adolescence, these studies have largely been small, cross-sectional, and often do not consider unique roles of parenting or sex. In the current study, we evaluated the interrelations among ecological stress, amygdala functioning, subsequent internalizing symptoms, and the moderating roles of parenting and sex, 9-and 10-year old preadolescents from the Adolescent Brain Cognitive Development study (ABCD). A subset of participants who met a priori quality control criteria for bilateral amygdala during the N-back faces versus places contrast (N = 7,385;Mean Age = 120 months, SD = 7.52; 49.5% Female) were included in the study. A Confirmatory Factor Analysis (CFA) was performed to create a latent variable of ecological stress, and multiple Structural Equation Model (SEM) models were conducted to evaluate the association among baseline ecological stress and internalizing symptoms one year later, the mediating role of amygdala activity, and moderating effects of parental acceptance and sex. The results revealed a significant association among ecological stress and subsequent internalizing symptoms, which was greater in males than females. There was no association between amygdala activity and ecological stress or subsequent internalizing symptoms, and no mediating role of amygdala, or moderating effect of parental acceptance, on the association between ecological stress and internalizing symptoms. An alternative mediation model was tested and revealed that parental acceptance mediated the association between ecological stress and internalizing symptoms, demonstrating lower internalizing symptoms among preadolescents one year later. Given the 4 Ecological stress, amygdala reactivity, and internalizing problems lack of association in brain function, ecological stress and internalizing symptoms in this registered report, effects from small studies should be reconsidered in larger samples.
