Objective: The aims of this study were to estimate the prevalence and
investigate the comorbidity and potential consequences of DSM-LII pers
onality disorders in the community. Method: A total of 810 adults were
examined in the second stage of the Eastern Baltimore Mental Health S
urvey in 1981, part of the National Institute of Mental Health Epidemi
ologic Catchment Area program. The subjects were directly examined by
psychiatrists using a semistructured method that allowed diagnosis of
all DSM-III personality disorders as well as other DSM-III psychiatric
disorders. Results: The prevalence of personality disorders in these
adults was 5.9% (9.3% when provisional cases were included). Men had h
igher rates than women, and subjects who were separated or divorced ha
d the highest rates. There was little comorbidity among specific perso
nality disorders, Subjects with personality disorders were significant
ly more likely to have a history of sexual dysfunctions, alcohol use d
isorders, and drug use disorders as well as suicidal thoughts and atte
mpts. In addition, they reported significantly more life events in the
past year. Among subjects with any axis I disorder, those with person
ality disorders were judged by the psychiatrists to be more in need of
treatment; however, only 21% were receiving treatment. Conclusions: P
ersonality disorders are relatively common in the community. They are
associated with axis I disorders and life events. Only one-fifth of th
e individuals who qualify for diagnoses of personality disorders in th
e community are receiving treatment.
