Abstract

This study sought to identify trajectories of drinking behavior change over time in a sample of adults with current alcohol use disorder (AUD). We conducted secondary analyses of seven waves of data from a prospective longitudinal study of 364 adults (mean age=44.0. years, SD=12.8. years) who met criteria for DSM-IV alcohol dependence (AD), 74.4% of whom were entering alcohol treatment. Participants were followed for 2 1/2 to 3. years with in-person interviews every 6. months. Results from latent class growth analyses of drinks per drinking day over 3. years indicated five trajectory classes: 1) Moderate Baseline. →. Slow Decli 2) Heavy Baseline. →. Stable Abstinent; 3) Heavy Baseline. →. Slow Decli 4) Heaviest Baseline. →. Steep Decline, and 5) Heaviest Baseline. →. Stable Heavy. Findings are consistent with previous research and suggest that these trajectory classes might represent longitudinal phenotypes of alcohol involvement across diverse samples. Treatment modality, Alcoholics Anonymous involvement, and purpose in life were associated with diverse trajectories of drinking behavior among adults with AD. AA involvement was associated with higher odds of membership in trajectory classes that showed declines in drinking from baseline, and having higher purpose in life predicted lower odds of membership in the Heaviest Baseline. →. Stable Heavy class. AA involvement predicts different pathways of recovery characterized by stable abstinence, steep declines, and/or slower declines in drinking over time. Higher purpose in life may protect against chronic heavy drinking by strengthening motivations to pursue goals that are unrelated to substance use.
