Patient-reported outcomes (PROs) offer valuable patient insights. The Health Assessment Questionnaire (HAQ) is a foundational PRO tool, with its disability index widely adopted globally.

Area of Science:

  • Rheumatology
  • Health Outcomes Research
  • Patient-Centered Care

Background:

  • Patient-reported outcomes (PROs) are crucial for assessing health status, functional capacity, and quality of life.
  • The Health Assessment Questionnaire (HAQ), developed in 1980, pioneered patient-oriented outcome assessment.
  • PRO instruments like the HAQ provide intrinsic patient knowledge vital for modern healthcare evaluation.

Purpose of the Study:

  • To review the historical development and evolution of the Health Assessment Questionnaire (HAQ).
  • To highlight the significance and widespread adoption of the HAQ disability index (HAQ-DI).
  • To discuss the different versions of the HAQ and their applications in clinical research.

Main Methods:

  • Review of the original development and subsequent revisions of the HAQ.

Related Experiment Videos

  • Analysis of the validation studies and correlations with other PRO instruments.
  • Examination of the translation and cultural adaptation of the HAQ-DI into multiple languages.

    • Main Results:

    • The HAQ assesses key patient-centered dimensions including disability, pain, medication effects, costs, and mortality.
    • The HAQ disability index (HAQ-DI) and short HAQ (global and pain VAS) remain largely unchanged.
    • The Full HAQ is periodically revised, while the HAQ-DI is available in over 60 languages.
    • The HAQ-DI is integrated into major health initiatives like NIH's "Road-map" Project and PROMIS.

    Conclusions:

    • The HAQ is a validated, reliable, and widely adopted PRO instrument.
    • The HAQ-DI's global reach and integration into research platforms underscore its importance.
    • The HAQ continues to be a cornerstone in patient-oriented outcome assessment.
