A cross-sectional study was performed to investigate the prevalence an
d predictors of suicidal ideation and past suicide attempt in an Austr
alian sample of human immunodeficiency virus (HIV)-positive and HIV-ne
gative homosexual and bisexual men. Sixty-five HIV-negative and 164 HI
V-positive men participated. A suicidal ideation score was derived fro
m using five items selected from the Beck Depression Inventory and the
General Health Questionnaire (28-item version). Lifetime and current
prevalence rates of psychiatric disorder were evaluated with the Diagn
ostic Interview Schedule Version-III-R. The HIV-positive (Centers for
Disease Control and Prevention [CDC] Stage IV) men (n = 85) had signif
icantly higher total suicidal ideation scores than the asymptomatic HI
V-positive men (CDC Stage II/III) (n = 79) and the HIV-negative men. H
igh rates of past suicide attempt were detected in the HIV-negative (2
9%) and HIV-positive men (21%). Factors associated with suicidal ideat
ion included being HIV-positive, the presence of current psychiatric d
isorder higher neuroticism scores, external locus of control, and curr
ent unemployment. In the HIV-positive group analyzed separately, highe
r suicidal ideation was discriminated by the adjustment to HIV diagnos
is (greater hopelessness and lower fighting spirit), disease factors (
greater number of current acquired immunodeficiency syndrome [AIDS]-re
lated conditions), and background variables (neuroticism). Significant
predictors of a past attempted suicide were a positive lifetime histo
ry of psychiatric disorder (particularly depression diagnoses), a life
time history of injection drug use, and a family history of suicide at
tempts. The findings indicate increased levels of suicidal ideation in
symptomatic HIV-positive men and high light the role that multiple ps
ychosocial factors associated with suicidal ideation and attempted sui
cide play in this population.
