This study examines the hardiness dimensions of commitment, challenge, and
control as resilience factors in adaptation among persons with symptomatic
HIV disease and AIDS. Two hundred participants completed self-report questi
onnaires measuring hardiness, psychological distress, quality of life, and
core personal beliefs. A series of standard multiple regression analyses re
vealed that high hardiness was significantly related to 1) lower psychologi
cal distress levels; 2) higher perceived quality of life in physical health
, mental health, and overall functioning domains; 3) more positive personal
beliefs regarding the benevolence of the world and people, self-worth, and
randomness of life events; and 4) lowered belief in controllability of lif
e events. Commitment was the hardiness factor that most frequently made a u
nique contribution to predicting adaptation in the regression models. Impli
cations of these findings for understanding HIV-related adaptation and for
clinical mental health intervention are considered Future directions in HIV
-related adaptation research are suggested.
