Abstract

Rationale: to examine the reliability and validity of the General Health Self-assessment, a modular questionnaire for self-assessment of quality of life (QoL) in human immunodeficiency virus (HIV) clinical trials and to describe the baseline QoL of participants in a large HIV clinical trial. Design: the domains assessed include health perceptions, physical, psychological and role/social functioning, health care utilization and symptom distress. Method: 1,694 subjects with early HIV infection enrolled in the AIDS Clinical Trials Group Protocol 175 completed the scale at baseline. Results: the domains demonstrated reliability, construct and discriminant validity. A worse QoL was associated with recent hospitalization and symptomatic status. Prior antiretroviral therapy was associated with higher health perceptions and well-being. The presence of symptom distress was related to lower QoL on the other scales. There was no relationship between QoL scales and the baseline CD4 count. Women showed a lower QoL than men on all scales, while ethnicity was related to differences in health perceptions and physical and psychological functioning. Conclusions: the General Health Self-assessment shows excellent potential as a measure of QoL for HIV-infected patients in clinical trials. Further research is necessary to determine the responsiveness of the scale to clinical and immunological changes in HIV-infected individuals.
