Notes: MAP = Mentorship for Alcohol Problems; TAU = Treatment As Usual (control). Values are represented as N (%), unless noted otherwise. Percentage calculations do not include missing observations.
a
Does not add to 100% because groups are not mutually exclusive. One observation missing for mood disorder among mentors.
b
P value for difference between MAP intervention and control; chi-square or Fisher Exact tests for categorical variables, t tests for difference in age, Wilcoxon rank sum tests for difference in days of drug or alcohol use in the month preceding intervention.
