Low Scores on California Psychological Inventory as Predictors of Psychopathology in Alcoholic Patients

Abstract

This study concerned the use of generally low California Psychological Inventory (CPI) profiles to predict elevated MMPI scores. In a sample of 110 subjects, a CPI profile with T-scores of 25 or less reflects major psychopathology and there is a 79% chance of correct prediction of MMPI T-scores over 80. As a further validation, a Goldberg Individual Index was established with a cut-off score of 70 to classify profiles as psychotic or nonpsychotic. It appears that the California Psychological Inventory can be expanded in making dual diagnoses for alcoholic patients. Scores can be used in treatment planning for alcoholic patients and to identify those individuals who should complete an MMPI for additional treatment planning and diagnoses.
