Health Assessment Questionnaire
HAQ; Stanford HAQ
The Health Assessment Questionnaire (HAQ) (1978) provides a comprehensive assessment of patient health outcome, as well as a means of longitudinal tracking of health-care outcomes (Bruce and Fries 2003a). It consists of five generic health dimensions: avoidance of disability, freedom from pain and discomfort, avoidance of adverse treatment effects, maintenance of low treatment costs, and postponement of death. Two formats are available. The two-page HAQ captures information on three scales: the HAQ Disability Index (HAQ-DI), the HAQ visual analog (VAS) pain scale, and the VAS patient global health scale. The full HAQ also collects information on drug toxicity data, direct cost data, and mortality-related data.
The HAQ is typically self-administered but can be given over the telephone or by interview in a clinical setting using trained interviewers. The two-page HAQ can be completed in about 5 min; the full HAQ takes between 20 and 30 min.
