“…When such criteria were reported, they varied considerably across studies. Criteria for defining alcohol abuse-dependence have included attendance at Alcoholics Anonymous meetings (e.g., Kovach, 1986), changes in overall rates of alcohol consumption in regions exposed to disaster (e.g., Gleser et al, 1981 ), a variety of social indices of alcohol abuse (e.g., E R. Adams & Adams, 1984), scores on self-report measures of alcohol-related problems (e.g., McFall et al, 1992), and the use of DSM-III or DSM-III-R criteria for alcohol abuse-dependence. Rates of comorbid alcoholism and PTSD obtained using DSM-III criteria are difficult to compare with those obtained using DSM-III-R criteria because the latter place less emphasis on physiological tolerance and withdrawal than did the former (Nace, 1988).…”
