Introduction[edit | edit source]
The Health Assessment Questionnaire - Disability Index (HAQ-DI) measures health related quality of life factors in various parts of a illness or injury process, and is not focused towards a single disease or disorder. It was designed to measured patient centered and patient assessed outcomes, and can be useful in conditions or life stages such as normal ageing, therapy of rheumatoid arthritis, developing risk factor models of osteoarthritis, and examination of mortality risk in rheumatoid arthritis. [1] It is a self-assessment tool used to measure functional ability in either different areas: rising, dressing and grooming, hygiene, eating, walking, reach, grip, and activities of independent living. [2]
It was developed in the 1980s, addressing general patient centered outcomes. [1] It was It has been administered by the Stanford Arthritis, Rheumatism, and Aging Medical Information System (ARAMIS) many times to assess clinical status, deem the effectiveness in clinical and observational trials, and outline health qualifiers. It has been adopted by the American College of Rheumatology for measuring physical function in rheumatoid arthritis studies. [1]
What is the HAQ-DI & Why use it[edit | edit source]
The HAD-QI is a quantitative tool used to assess health related quality of life assessments related to many types of injuries or illnesses. Since it was adopted through rheumatology, it can be known to only classify diseases, but as mentioned it is used across varies. Instead of being classified as 'disease specific', it should be classified as 'generic', since it it assesses the dimensions of death, disability, drug side effects, discomfort, and economic costs. [1]
Measuring or assessing Health related quality of life is important at any stage of any condition or or injury. A valid and reliable tool, which can measure and assess over long periods greater than 6 weeks, is needed for such a measurement. [1]

- Be free of Pain and Discomfort
- Avoid adverse Treatment Effects
- Keep dollar costs of treatments low
- Prevent the likelihood of Death
The questionnaire also includes sections on drug side effects, medical costs, and other sections on demographics, lifestyle, and health behaviors. [1]
The most commonly used version is the HAQ, which is the 'short' or 22-page version. This version includes the HAQ Disability Index (HAQ-DI), the HAQ Visual Analog Scale (VAS) for pain, and the VAS patient global health scale. [1]
