Example of Health Domain Questions
MOBILITY
Q2010. Overall in the last 30 days how much difficulty did you have with moving around?
1. None 2. Mild 3. Moderate 4. Severe 5. Extreme/ Cannot do
Q2011. In the last 30 days, how much difficulty did you have in vigorous activities,
such as running 3km (or equivalent) or cycling?
1. None 2. Mild 3. Moderate 4. Severe 5. Extreme/ Cannot do
9
The World Health Survey
Cross population comparability
- Common set of survey questions
- Standardized translation procedure
- Cognitive interviewing
- Ensuring that questions are reliable and valid
- Measuring and adjusting for shifts in cut points

Vignettes for Health State Descriptions
Mobility
[Mary] has no problems with walking, running or using her hands, arms and legs. She
jogs 4 kilometres twice a week.
[Anton] does not exercise. He cannot climb stairs or do other physical activities
because he is obese. He is able to carry the groceries and do some light household work.
