Personality disorders in smokers and cocaine dependent subjects who request treatment : a comparative study

Abstract

The aim of this study was to assess and compare the presence of personality disorders in smokers and in subjects with cocaine dependence at the beginning of the treatment, with the use of the Spanish version of the Millon Clinical Multiaxial Inventory-II (MCMI-II; Millon, 1997). The sample was composed of 304 subjects, 102 of them in treatment for cocaine dependence, and 202 attending a smoking cessation treatment. The results show signifi cant differences between the two groups in all personality scales, except in the dependent and the histrionic scales. We found that cocaine-dependent patients obtain higher scores than smokers in the hypomania, alcohol abuse, drug abuse, psychotic, psychotic delusion, sincerity and alteration scales. We conclude that the personality profi le of cocaine-dependent patients is signifi cantly different from the smokers’ profile.
