Understanding the SF-36 Questionnaire
What is the SF-36?
The SF-36, or Short Form (36) Health Survey, is a patient-reported survey designed to measure health status across multiple dimensions. Developed in the late 1980s by researchers at the Medical Outcomes Study, it has become one of the most utilized tools for assessing quality of life related to health.
The questionnaire covers eight health domains:
- Physical Functioning
- Role Limitations due to Physical Health
- Bodily Pain
- General Health Perceptions
- Vitality (Energy/Fatigue)
- Social Functioning
- Role Limitations due to Emotional Problems
- Mental Health (Psychological Well-being)
These domains collectively provide a comprehensive overview of an individual's health status, enabling targeted interventions and better understanding of health outcomes.
Why Use the SF-36?
The SF-36 is favored for several reasons:
- It is brief yet comprehensive.
- It is validated across diverse populations and languages.
- It facilitates comparison across different diseases, treatments, and populations.
- It supports both clinical assessments and research studies.
