Long-term effects of alcohol consumption on anxiety in adults: A systematic review.

OBJECTIVE: Despite the high prevalence and comorbidity of alcohol consumption and anxiety, it is unclear whether alcohol consumption influences long-term anxiety. This study aimed to systematically review the literature on the long-term longitudinal effects of alcohol consumption on anxiety in adults. METHODS: EMBASE, PsychInfo, Medline, and Web of Science databases were systematically searched from inception to April 12th, 2024. Articles analysing the relationship between alcohol consumption and anxiety symptoms or anxiety disorder diagnosis at least three-months later in adults were eligible. Articles were screened and extracted by two independent reviewers with study quality assessed using the Mixed Methods Appraisal Tool. RESULTS: From 884 records, eight studies of mixed quality met inclusion criteria. One study using a sample representative of the USA population found low volume consumption was associated with lower long-term anxiety. All other studies used a convenience sample or a specific medical population sample. The significance and direction of the relationship between alcohol consumption and long-term anxiety in these studies varied, likely due to differences in alcohol consumption thresholds used and populations studied. CONCLUSIONS: A paucity of research on the longitudinal effects of alcohol consumption on anxiety was found, highlighting a significant gap in the research literature. Furthermore, existing research, primarily focussed on clinical subpopulations, has yielded mixed results. Further research is needed to explore the longitudinal dose dependent impact of alcohol consumption on anxiety using samples representative of national populations.

Why do adults drink alcohol? Development and validation of a Drinking Motives Questionnaire for adults.

OBJECTIVE: The Drinking Motives Questionnaire-Revised (DMQ-R; Cooper, 1994) is frequently used to assess adult drinking motives despite being designed for younger drinkers. This study aimed to develop and validate a Drinking Motives Questionnaire for Adults (DMQ-A). METHOD: A convenience sample of 1,617 adults (25-65-year-olds; Mage = 51.4, SD = 10.8; 67% female) and 145 young-adults (18-24-year-olds; Mage = 20.8, SD = 2.0; 72% female) who reported drinking at least monthly were asked how often they consumed alcohol due to 53 drinking motives. Using item endorsement and exploratory factor analysis on half of the split sample of adults, 20 items were selected for the DMQ-A. RESULTS: The DMQ-A was found to have social, coping, confidence, taste, and enhancement dimensions. The DMQ-R conformity dimension was replaced by one of drinking for confidence and a novel drinking for taste dimension was identified. The second half of the split sample was used to demonstrate the DMQ-A's adequate model fit (CFI = 0.93), good internal consistency (α = .81-.90) and 6-month test-retest reliability (r = .65-.74), correlation with corresponding DMQ-R dimensions (r = .90-.96), and better model fit for adults than young-adults (ΔCFI = .03). The DMQ-A also demonstrated higher endorsement for each of its dimensions and better model fit than the DMQ-R among adults (ΔCFI = .05). Like the DMQ-R, DMQ-A coping and enhancement dimensions correlated with alcohol consumption and harmful drinking (r = .19-.42). CONCLUSIONS: The DMQ-A is a promising tool for future research or clinical application involving adult alcohol use. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Shifts in alcohol consumption during the COVID-19 pandemic: early indications from Australia.

BACKGROUND AND AIM: The effect of the COVID-19 pandemic on alcohol consumption is currently unclear. This study aimed to provide early estimates of how stress and demographics will interact with shifts in harmful alcohol consumption from before the COVID-19 outbreak to 2 months into social distancing. DESIGN: Cross-sectional convenience sample. SETTING: Australia. PARTICIPANTS: A total of 1684 Australians aged 18-65 years who drink at least monthly. MEASUREMENTS: Items from the Alcohol Use Disorders Identification Test (AUDIT) and the stress subscale of the Depression Anxiety and Stress Scale (DASS). FINDINGS: Overall, harmful drinking decreased during social distancing measures in our sample [2019 score = 8.2, 95% confidence interval (CI) = 7.9-8.4; during the pandemic = 7.3, 95% CI = 7.1-7.6]. Younger drinkers, particularly young women, decreased their consumption the most, but there was a small increase in consumption in middle-aged women. Drinkers experiencing high levels of stress also reported a relatively higher shift in harmful consumption compared with those with low levels of stress (ß = 0.65, P = 0.003), despite reporting a small decrease overall. CONCLUSIONS: The closure of licensed premises and social distancing measures in Australia in response to the COVID-19 outbreak appear to have reduced harmful alcohol consumption in younger drinkers, particularly young women.
