Notes: All models control for baseline age, race, education, employment status, marital status, drinks per drinking day, drinking severity, number of psychiatric symptoms, number of previous treatment episodes, and substance use treatment at the 1.5-year follow-up. Gender and extroversion were measured at baseline (Time 1 [T1]). Alcoholics Anonymous (AA) membership and substance use treatment were measured at the 1.5-year follow-up (T2). Sobriety was measured at the final follow-up, 2.5–3 years after baseline (T3). Bold indicates statistical significance. OR = odds ratio; CI = confidence interval.
