In the analyses with Class 5 “consistent low risk drinking” as the reference class (see Figure 1), greater alcohol dependence severity was associated with a higher probability of membership in all other classes, as compared to Class 5. Greater percent of heavy drinkers in the social network and greater negative mood symptoms predicted higher probability of being in Class 1 “persistent heavy drinking” versus Class 5. Older age predicted a significant lower probability of expected membership in Class 1 “persistent heavy drinking” (OR=0.94, 95% CI: 0.90, 0.98), Class 2 “relapse-to-heavy drinking” (OR=0.93, 95% CI: 0.90, 0.96), Class 3 “mixed heavy and low risk drinking” (OR=0.95, 95% CI: 0.92, 0.97), Class 4 “heavy drinking-to-abstinence” (OR=0.94, 95% CI: 0.90, 0.98), and Class 6 “abstinence-to-low risk drinking” (OR=0.91, 95% CI: 0.88, 0.95), as compared to Class 5.
