An adapted version of the psychiatric evaluation schedule of Pfeiffer (1975) was used to evaluate the psychological health of the respondents:

1. What are the date, month, and year?
2. What is the day of the week?
3. What is the name of this place?
4. What is your phone number?
5. How old are you?
6. When were you born?
7. Who is the current president?
8. Who was the president before him?
9. What was your mother's maiden name?
10. Can you count backward from 20 by 3's?

The 4 distinct levels of intellectual functioning are:
1)intact intellectual functioning, 2)mild intellectual impairment, 3)moderate intellectual impairment, and 4)severe intellectual impairment.

For white subjects with at least some high school education, but not more than high school education, the following criteria have been established:
0-2 errors (intact)
3-4 errors (mild)
5-7 errors (moderate)
8-10 errors (severe)

In this study, the scores of the scale can range from 15 to 30, with the higher scores representing fewer psychological symptoms and therefore a healthier condition.
