The WHODAS 2.0 (World Health Organization Disability Assessment Schedule 2.0) is a widely used instrument for measuring health-related quality of life and disability. This calculator helps you compute your WHODAS 2.0 score based on your responses to the questionnaire.
What is WHODAS 2.0?
WHODAS 2.0 is an updated version of the original WHODAS instrument designed to assess disability and health-related quality of life. It consists of 30 items covering various aspects of functioning, including physical, social, and psychological domains.
The questionnaire uses a 5-point Likert scale (0 = no problem to 4 = extreme problem) to measure the severity of problems in different areas of life. The total score ranges from 0 to 120, with higher scores indicating greater disability.
Note: WHODAS 2.0 is not a diagnostic tool but provides a general measure of disability that can be useful for health professionals, researchers, and individuals tracking their own health status.
How to Use This Calculator
To calculate your WHODAS 2.0 score:
- Complete the WHODAS 2.0 questionnaire by answering each of the 30 items with your current level of functioning.
- Enter your responses into the calculator below.
- Click "Calculate" to generate your score.
- Review the interpretation of your results.
Formula: The total WHODAS 2.0 score is calculated by summing the responses to all 30 items. The maximum possible score is 120.
Interpreting Your Results
The WHODAS 2.0 score provides a general measure of disability. Here's how to interpret your results:
| Score Range | Interpretation |
|---|---|
| 0-20 | Minimal disability |
| 21-40 | Mild disability |
| 41-60 | Moderate disability |
| 61-80 | Severe disability |
| 81-120 | Extreme disability |
These ranges are general guidelines. Individual interpretations may vary based on context and specific circumstances.
Worked Example
Let's calculate a sample WHODAS 2.0 score. Suppose a person responds to the 30 items as follows:
- 15 items with a score of 0 (no problem)
- 10 items with a score of 1 (mild problem)
- 5 items with a score of 2 (moderate problem)
Calculation: (15 × 0) + (10 × 1) + (5 × 2) = 0 + 10 + 10 = 20
This person's WHODAS 2.0 score would be 20, indicating minimal disability.
