Persistent attention-deficit/hyperactivity disorder predicts socially oriented, but not physical/physiologically oriented, alcohol problems in early adulthood.

Abstract

BACKGROUND\nAlthough individuals with histories of childhood attention-deficit/hyperactivity disorder (ADHD) report more alcohol-related problems in adulthood than those without ADHD, it is unknown whether there are group differences in certain types of alcohol problems. We tested whether the nature of alcohol problems differed for individuals with and without childhood ADHD, as well as adulthood-persistent ADHD, to facilitate a personalized medicine approach for alcohol problems in this high-risk group.\n\n\nMETHODS\nData were drawn from a prospective, observational study. Children diagnosed with ADHD and demographically similar individuals without childhood ADHD were followed prospectively through young adulthood (N\xa0=\xa0453; 87.6% male). ADHD symptom persistence was assessed using self-reports and parent reports. Alcohol problems and heavy drinking were assessed repeatedly from 18-30\xa0years old to construct lifetime measures.\n\n\nRESULTS\nFull-sample confirmatory factor analyses identified 5 alcohol problem types: interpersonal problems/risky behaviors, occupational/academic impairment, impaired control/treatment seeking, tolerance/withdrawal, and drinking to blackout. Latent class analyses of items within each type yielded the best fit for 3-class solutions for all sets of items except blackout drinking, for which 2\xa0classes emerged. Children with ADHD were more likely than those without ADHD to belong to high-risk latent classes for interpersonal problems/risky behaviors, occupational/academic problems, and impaired control (the high-risk class that indexed treatment-seeking behavior). These effects were driven by individuals whose ADHD symptoms persisted into adulthood. Few group differences emerged for tolerance/withdrawal and blackout drinking, except that individuals with only childhood ADHD (no persistence) were more likely to belong to the low-risk groups than those with adulthood-persistent ADHD and without ADHD.\n\n\nCONCLUSIONS\nIndividuals with ADHD histories whose symptoms persist into adulthood may be more likely to experience socially oriented alcohol problems and impaired control/treatment seeking than individuals without an ADHD history and those with childhood ADHD only. Tailored alcohol prevention and treatment programs may benefit this high-risk population.
