Note. Resolved nonabstinent group is the referent group.
p < .05,
p < .01.
ASDE = Alcohol-Savings Discretionary Expenditure index; OR = odds ratio; CI = confidence interval; Days well functioning = abstinent plus drinking days below binge drinking thresholds during the pre-resolution year (adjusted for gender). Continuous predictors were standardized. Participants (n = 6) who had unreasonable DD response patterns or never chose a locally favorable option throughout entire MM task sessions were excluded in the analyses.
