Alcoholism and Personality Disorders

Alcohol Dependence and Personality Disorders: A comparative Study.

Aims: To describe the frequency and profile of personality disorders related to alcohol dependence, and to compare them with non-addictive disorders and with normal population.

Methods: In this cross-sectional clinical-epidemiological study, using the International Personality Disorder Examination and the Millon Clinical Multiaxial Inventory-II for personality disorders, 158 consecutively recruited alcohol-dependent patients attending a psychiatric outpatient clinic were compared with 120 consecutively recruited psychiatric patients with non-addictive disorders, and 103 subjects from the general population chosen to match the patient samples for age, gender and socioeconomic level.

Results: Of the alcohol-dependent patients, 44.3%, and of the general clinical sample, 21.7% (vs 6.8% of the normative sample) showed at least one personality disorder.

Obsessive-compulsive personality disorders were most prevalent (12%), followed by antisocial, paranoid and dependent personality disorders (7% each). Most of them showed only one personality disorder.
