Abstract:
Using the MCMI-III, we studied rates of personality disorders among 443 inpatient drug abusers (i.e., 160 opiate addicts and 283 cocaine addicts). For both samples the disorders of antisocial (60%), passive-aggressive (negativistic) (34%), and depressive personality disorders (32%) showed higher prevalence rates. Previous studies (N = 13) using different measures (e.g., SCID, SDIP, MCMI-I) reported similar findings in terms of overall prevalence of specific personality disorders, although actual rates varied by population.
