Blind-rated DSM-III-R lifetime psychiatric diagnoses (American Psychiatric Association, 1987) were derived from the Schedule for Affective Disorders and Schizophrenia-Lifetime Version (SADS-L). A clinical social worker (B.A.), knowledgeable in the tribe’s customs and culture, conducted the SADS-L interviews. The prevalence of lifetime alcohol use disorders (AUD) (nearly all alcohol dependence) in this sample was 73% in men and 47% in women (Enoch et al, 2006b) however 63% of the alcoholics had been abstinent for at least one year. The sample included 181 alcoholics (97 men, 84 women) and 130 non-alcoholics (34 men, 96 women).
