The differences in DSM-III-R psychiatric diagnoses between HIV-positiv
e and HIV-negative patients were assessed. Subjects were patients admi
tted for psychiatric treatment to a metropolitan, state-supported faci
lity. Experimental group subjects consisted of all adult patients iden
tified as HIV-positive. Control group subjects were non-HIV-positive a
dult patients of the same gender and within 10 years in age of the exp
erimental group subjects. Results suggest that HIV-positive subjects w
ere significantly more likely to have received a personality disorder
diagnosis and to have a history of intravenous psychoactive substance
use. The likelihood of HIV-positive subjects to have a lower incidence
of thought disorder diagnosis than non-HIV-positive subjects approach
ed significance. No significant differences were obtained for diagnose
s of psychoactive substance use disorders, psychoactive substance-indu
ced organic mental disorders, mood disorders, or schizoaffective disor
der. The diagnosis of a personality disorder and/or prior intravenous
psychoactive substance use are possible indicators of, and additional
risk factors for, the HIV-positive status of a patient.
