The study sample comprised 43 LTAA (19 females, mean age = 49.0 years, SE = 0.8), who had abstinence durations ranging between 1.5 and 32.2 years (median = 3.5 years, mean = 7.6 years, SE = 1.2), 31 STAA (11 females, mean age = 49.1 years, SE = 1.3), with abstinence durations ranging between 6.0 and 14.4 weeks (median = 9.9 weeks, mean = 9.9 weeks, SE = 0.5), and 72 NAC (35 females, mean age = 48.7 years, SE = 0.8). Groups did not differ on age, F(2, 143) = 0.05, P = 0.95, nor on proportion of male and female participants in each group, χ2(2, N = 146) = 1.52, P = 0.47. Participants were recruited through postings at university campuses, bulletin boards, Craigslist, community and health centers, alcoholic anonymous (AA) meetings, and subject referrals. All alcoholic participants had attended AA sessions and/or other alcohol treatment programs.
