Abstract:
This study assessed personality disorders (PDs) in 158 alcohol-dependent outpatients (62 manifesting cocaine abuse and 96 without cocaine abuse) with the International Personality Disorders Examination interview between 2003 and 2006. Thirty-nine alcohol-dependent/cocaine abusers (62.9% of this group) and 51 only alcohol-dependent patients (53.1% of this group) manifested at least one PD. There were no statistically significant differences between groups in the overall prevalence rate of PDs. The most prevalent PDs, among the alcohol-dependent/cocaine abusers, were antisocial (21%), narcissistic (14.5%), and borderline (11.3%) PDs. The most frequently diagnosed PDs among the only alcohol-dependent patients were obsessive-compulsive (20.8%), paranoid (10.4%), and dependent (9.4%) PDs. There were significant differences between the groups. The study limitations are discussed.
