Assessing health-related quality of life in persons infected with huma
n immunodeficiency virus (HIV) is extremely important, but most availa
ble scales are too long, contain items that are not relevant for such
persons, or do not assess important signs and symptoms of HIV infectio
n. This study presents a new set of scales for assessing the symptoms
and functioning of persons infected with HIV and reports data on their
reliability and validity collected in face-to-face interviews with 18
9 patients receiving primary care. This study also assesses the associ
ations among systems, functional impairment, and global health assessm
ents. The scales are easy to administer, are reliable, and serve as va
lid measures of quality of life. Fatigue, functional status, and avera
ge severity of all symptoms were the best predictors of overall percei
ved health status. Psychological well-being and perceived health statu
s were the best predictors of overall perceived health status. Psychol
ogical well-being and perceived health status were the strongest corre
lates of life satisfaction. When assessing the health-related quality
of life of persons infected with HIV, this study recommends utilizing
a comprehensive set of measures that allows one to examine both discre
te symptoms and the more diffuse impact of illness on functioning, men
tal health, and quality of life.
