The relationship of control beliefs to psychological adjustment was in
vestigated in a sample of 24 gay men diagnosed with AIDS, participants
in the University of California, Los Angeles site of the Multicenter
AIDS Cohort Study (MACS). Distinctions between generalized contingency
beliefs and specific competence beliefs and between personal and vica
rious control beliefs were included in the questionnaire and interview
measures administered. The results support these distinctions and ind
icate that beliefs in personal control over day-to-day symptoms and ov
er course of illness were positively related to adjustment, whereas be
liefs in control by others over course of illness and over medical car
e and treatment were negatively related to adjustment. These relations
hips appeared to be strongest for men who reported poorer health. Thes
e associations were not accounted for by locus of control beliefs, neg
ative affectivity, or time since diagnosis with AIDS.
