The development of new pharmaceutical interventions for persons with human immunodeficiency virus (HIV) infection has resulted in extended survival and a need for valid, reliable and responsive instruments to assess health-related QoL (HRQoL).
This paper reviews the reliability and validity of an HRQoL instrument, the AIDS Health Assessment Questionnaire (AIDS-HAQ), among persons participating in an observational database of HIV infection.
The AIDS-HAQ includes nine subscales : disability, energy, general health, pain, cognitive functioning, mental health, social functioning, health distress and symptoms.
Individuals complete the AID-HAQ quarterly.
Data are reported for 440 individuals entering the study with early HIV infection.
Fifty-nine progressed to symptomatic disease and 109 to AIDS after 1 year.
The subscales of the instrument resulted in high internal consistency reliability (range=0.79-0.88).
Concurrent validity data reflected the ability to distinguish between patients with increasing disease severity.
In all domains, except cognitive functioning, individuals who progressed to AIDS had significant decrements (p<0.01) in HRQoL compared whith symptomatic and asymptomatic patients.
Significant decrements (p<0.01) were observed for disability, general health, energy and symptoms for patients who progresssed to symptomatic disease from an asymtomatic status.
Individuals who had decreasing CD4+counts also had significant declines. (...)
