Adolescent precursors of young adult drinking motives.

ABSTRACT: INTRODUCTION:Numerous cross-sectional and shorter-term longitudinal studies have supported the role of drinking motives as potent proximal predictors of alcohol phenotypes (e.g., alcohol use, heavy episodic drinking). However, missing from this literature is a focus both on the stability of drinking motives across young adulthood and on adolescent precursors of drinking motives. METHODS:We investigated the adequacy of using a latent trait-state model (LTSM) to investigate three-wave data on social, enhancement, and coping motives for drinking with a community sample of young adults (N?=?1004) at the mean ages of 23.8?years, 28.9?years, and 33.5?years. We further investigated adolescent (M age?=?16.73?years) predictors of young adult drinking motives using data collected on the sample approximately seven years prior to the first young adult data collection. RESULTS:Findings indicated that all three drinking motives across young adulthood were modeled adequately via the LTSM, and that drinking motives manifested high stability (i.e., rank order) across individuals. Significant common (e.g., being male, alcohol-using peers, stressful life events, boredom susceptibility) and specific (e.g., depressive symptoms for coping motives; heavy episodic drinking for enhancement motives) adolescent precursors of young adult drinking motives were identified. CONCLUSIONS:Common and unique adolescent factors predicted trait-like drinking motives during young adulthood. These findings suggest the utility of intervening during the teen years to prevent or interrupt the development of cognitive motivations that encourage alcohol use for the purpose of affect regulation.

Project description:Background and aimsExisting evidence for a link between alcohol use and memory impairments in adolescents and young adults is largely correlational. We aimed to determine whether associations between drinking and episodic memory were consistent with a causal effect of drinking or accounted for by familial factors confounding such associations. Because cannabis use is associated with a similar pattern of performance on episodic memory measures, we assessed whether any associations might be attributable to concurrent cannabis use.Design, setting and participantsObservational study of individuals aged approximately 20-29 years, comprising two independent population-based cohorts of twins. A co-twin-control design permitted an estimate of alcohol exposure effects free of shared genetic and environmental confounding influences. Significant associations were followed-up with twin-difference analyses. Propensity scores derived from measures collected at age 11 were used to adjust for unshared confounders. Participants in both cohorts were assessed from the age of 11 (n = 1251) under the auspices of the Minnesota Center for Twin and Family Research.MeasurementsRegression analyses with cumulative alcohol use as the predictor of interest. Multiple measures of attention, learning and memory from a widely used episodic memory task constituted dependent variables.FindingsDrinking was associated with poorer attention (P ≤ 0.003) and learning (P ≤ 0.008). Results were similar across the two cohorts. The within-pair effect in twin-difference analyses was significant only for measures of learning (P-values ≤ 0.004). Results were not due to measured unshared confounders or cannabis use. Drinking in adolescence (to age 20) and early adulthood (between 20 and 29) exerted independent effects on learning.ConclusionsThere appears to be a robust and specific association between drinking and learning that can be reproduced across cohorts, is not easily accounted for by confounding factors or concurrent cannabis use and is consistent with a causal influence of drinking.

Project description:BackgroundRates of alcohol use disorders in individuals with bipolar disorder are 3 to 5 times greater than in the general population and exceed rates of alcohol use disorders reported in other affective and anxiety disorders. Despite this high rate of comorbidity, our understanding of the psychosocial and neural mechanisms that underlie the initiation of alcohol misuse in young adults with bipolar disorder remains limited. Prior work suggests that individuals with bipolar disorder may misuse alcohol as a coping mechanism, yet the neural correlates of coping drinking motives and associated alcohol use have not been previously investigated in this population.MethodsForty-eight young adults (22 bipolar disorder type I, 26 typically developing; 71% women; average age ± standard deviation = 22 ± 2 years) completed the Drinking Motives and Daily Drinking Questionnaires, and a Continuous Performance Functional magnetic resonance imaging (fMRI) Task with Emotional and Neutral Distracters. We calculated the relative difference in anterior cingulate cortex (ACC) functional coupling with the anterior insula and amygdala in response to emotional distracters compared with neutral stimuli and investigated the relations with coping drinking motives and alcohol use.ResultsAcross all participants, coping drinking motives were associated with greater quantity of recent alcohol use. In individuals with bipolar disorder, greater ACC-anterior insula functional coupling was associated with greater coping drinking motives, and greater quantity and frequency of recent alcohol use. The relative difference in ACC-anterior insula functional coupling was not associated with coping drinking motives or alcohol use in the typically developing group. Greater ACC-anterior insula functional coupling in individuals with bipolar disorder was also associated with greater anxiety symptoms and recent perceived psychological stress. Exploratory analyses suggest that the relations between ACC-anterior insula functional coupling and coping drinking motives may be confounded by anticonvulsant use.ConclusionResults suggest that a difference in ACC-anterior insula functional coupling during emotion processing may underlie alcohol use as a maladaptive coping mechanism in young adults with bipolar disorder.
