Relationships of personality disorders with problem severity in methadone patients.

Abstract

The prevalence of DSM-III-R personality disorders were assessed in a sample of 179 male methadone maintained opiate addicts. The discriminant validity of three personality disorder (PD) groupings were compared with respect to Axis I disorders, functioning in a number of important life areas, risk for HIV infection, and social judgment/sensitivity. Results showed that a PD, regardless of the number or type, identified patients with more employment, family/social, and psychiatric problems, increased risk for HIV infection, and poor social judgment/sensitivity. Few differences were revealed when three clusters of PDs (Cluster A, B, and C) were compared. With few exceptions, subjects with antisocial PD were no worse off than those with any other PD with respect to current functioning.
