Princeton, NJ: Princeton University Press). Individuals were informed at the start of the test that their data would be saved. When they completed the test they were asked to confirm that the responses they had given were accurate and could be used for research, only those who confirmed are included in this dataset (75.7% confirmed).

I feel that I am a person of worth, at least on an equal plane with others. Q2. I feel that I have a number of good qualities. Q3. All in all, I am inclined to feel that I am a failure. Q4. I am able to do things as well as most other people. Q5. I feel I do not have much to be proud of. Q6. I take a positive attitude toward myself. Q7. On the whole, I am satisfied with myself. Q8.
