Abstract

We developed a MMPI alcoholism scale based on adult medical patient samples. Our criterion group consisted of 736 inpatients (525 males; 211 females) diagnosed as having alcoholism according to DSM-III criteria. Three contrast samples that totaled 13,120 individuals were used for control purposes. MMPI items were chosen by means of logistic regression. The 33 items yielded by this procedure formed a provisional scale (CAL, for common alcoholism logistic) that worked equally well for males and females. With new cross-validation samples, with sensitivity (proportion of alcoholics correctly identified) set at 90%, the specificity (proportion of nonalcoholics correctly identified) ranged from 90% to 96% for selected contrast samples. We conclude that this scale shows promise as a screening device in similar populations.
