Note: Self-rated health is summed over four questions (1. How would you rate your general health status? 2. How would you rate your general health status compared to 5 years ago? 3. How would you rate your health status compared to others in your age group? 4. Do you think your health prevents you from doing things you would like to do?) The items were standardized to a mean of 0 and a standard deviation of 1 before summing.
