In-the-Moment Drinking Characteristics: An Examination Across Attention-Deficit/Hyperactivity Disorder History and Race.

ABSTRACT: BACKGROUND:Adults with a history of childhood attention-deficit/hyperactivity disorder (ADHD) and Black drinkers are at elevated risk for alcohol problems and alcohol use disorder. Processes that increase risk for these distinct populations have not focused on in-the-moment behaviors that occur while drinking. The present study examined in-the-moment drinking characteristics (i.e., location, social context, day, time, drink type, speed of consumption) that may differ for individuals with and without ADHD histories or for Black and White drinkers. We also examined the interplay among these in-the-moment drinking characteristics to further understanding of contexts when risk may be momentarily increased. METHODS:As part of a larger study, 135 individuals (Mage  = 27.81, 69.6% male, 45.9% ADHD, 69.6% White) completed a 10-day ecological momentary assessment protocol that included self-initiated reports following consumption of an alcoholic drink. Hypotheses were tested using multilevel modeling. RESULTS:Controlling for multiple demographic covariates, Black drinkers drank significantly more quickly than White drinkers and were more likely to consume hard liquor-containing beverages. Differences in drinking speed remained significant when adjusting for Black drinkers' greater likelihood to consume liquor-containing beverages and momentary experience of discrimination; however, Black drinkers' increased likelihood to consume liquor-containing beverages was no longer significant when adjusting for momentary experience of discrimination. Individuals with ADHD histories did not differ from those without ADHD histories in any in-the-moment drinking characteristics. ADHD and race did not interact to predict any drinking characteristic. CONCLUSIONS:Differences in speed of alcohol consumption and propensity to consume liquor-containing beverages may contribute to increased risk for alcohol problems experienced by Black drinkers compared to White drinkers.
