What Is the Short Form 36 (SF-36) Questionnaire?
Overview of the SF-36
The Short Form 36 (SF-36) is a patient-reported survey designed to measure health status across eight key 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
These domains collectively provide a comprehensive picture of a person’s perceived health and its impact on their daily life.
History and Development
The SF-36 was developed in the early 1990s as part of the Medical Outcomes Study (MOS), aiming to create a standardized measure of health-related quality of life. Its brevity, along with robust psychometric properties, quickly established it as a gold standard in health measurement tools.
Advantages of Using SF-36
- Short and easy to administer
- Applicable across diverse populations and diseases
- Provides both physical and mental health insights
- Validated in numerous languages and cultures
- Suitable for longitudinal studies to monitor changes over time
