Measure of depressive symptoms (Modified CES-D)
Depressive symptoms are assessed with a modified, 10-item version of the Center for Epidemiologic Studies Depression scale (CES-D)*. Participants are asked whether or not they experienced each of ten symptoms much of the time in the past week. The score is the total number of symptoms experienced. Items 4 and 7 are reverse coded so the response is consistent with depressive symptom =1.
Participants are presented with the following items:
| Item no. | Item | Calc | Item no. in 20-item CES-D* |
|---|---|---|---|
| 1 | I felt depressed. | Yes=1 | 6 |
| 2 | I felt that everything I did was an effort. | Yes=1 | 7 |
| 3 | My sleep was restless. | Yes=1 | 11 |
| 4 | I was happy. | No=1 | 12 |
| 5 | I felt lonely. | Yes=1 | 14 |
| 6 | People were unfriendly. | Yes=1 | 15 |
| 7 | I enjoyed life. | No=1 | 16 |
| 8 | I felt sad. | Yes=1 | 18 |
| 9 | I felt that people disliked me. | Yes=1 | 19 |
| 10 | I could not get going. | Yes=1 | 20 |
Note on missing data: The score is rescaled to be out of 10 by averaging the non-missing item values and multiplying by 10. For example, if only 8 questions are answered, and the sum is 6, then 6/8 = 0.75, multiplied by 10 results in a score of 7.5. This is only done if less than 5 items are missing.
