Abstract (Englisch)

In this study, the prevalence of psychiatric diagnosis including personality disorder was assessed among 101 alcoholic patients and 226 former opiate addicts in methadone maintenance treatment, all followed in different outpatient units of the Substance Abuse Division in Geneva. A mental health assessment protocol with validated diagnostic and screening instruments was proposed, including the ICD-10 symptom checklist plus series of severity rating scales. Overall, 70 % of alcoholic patients, and 68% of drug addicts were diagnosed with at least one personality disorder. Among patients with harmful use of or dependence on alcohol as principal ICD-10 diagnosis, the Cluster C and particularly anxious type of personality disorder was most frequently diagnosed, whereas among those with harmful use of or dependence to drugs (heroin principally) as principal ICD-10 diagnosis, the Cluster B and particularly emotionally unstable type of personality disorder was most prevalent. The type of personality disorder is an important determinant for the type of substance principally and the number of substances abused. One third of patients in methadone maintenance treatment present a harmful use of or dependence on alcohol. Type and number of personality disorders play a role in the outcome (drug problem, severity of mood and anxiety disorders ) of the substance abuse treatment. The treatment of substance abusers with a personality disorder especially those with Cluster B or multiple personality disorders require an integrated approach combining substance abuse, axe I and axe II disorders treatment. New therapeutic strategies for dual diagnosis patients should be developed, tested and evaluated.
