Health Assessment Questionnaire (HAQ): Functional Status
The Health Assessment Questionnaire measures how arthritis affects daily activities. Doctors use this self-report tool to track disability and see how well treatment plans improve physical function.

Health Assessment Questionnaire (HAQ)
The Health Assessment Questionnaire (HAQ) is a key tool in rheumatology for measuring functional ability. It assesses disability in arthritis patients by tracking difficulty with daily tasks like dressing and walking. It helps doctors monitor disease progression and how well treatments work in clinical settings.

What is Health Assessment Questionnaire (HAQ)
The Health Assessment Questionnaire (HAQ) is a trusted tool for measuring physical function in arthritis. It tracks disability levels effectively. This survey looks closely at daily tasks like getting dressed, walking or eating. It covers eight specific categories of functioning to see exactly how well a patient manages their regular routine. Patients rate their ability on a simple scale from zero to three. Zero means no trouble at all while a score of three means they cannot do the task. The form also checks if they need special devices or help from another person to manage daily life properly. Doctors use this widely in rheumatology to see if treatments work. It is quick to fill out and gives a clear picture of patient health. This data helps clinicians make better choices about care plans and medication changes, ensuring patients get the right support they need for the long haul.
The Health Assessment Questionnaire is scored using a standard method that looks at daily functional limits. You will rate items across eight categories, such as dressing and walking, on a scale from 0 for no difficulty to 3 for unable to do. The highest mark in each section sets the category score. If a patient uses devices or needs a hand from others, that score bumps up to a 2. Finally, average the eight category scores to get a Disability Index between 0 and 3. It is a reliable way to track physical function changes in the clinic.
