Table 1.

Affect scale items (adapted from the CAMDEX depression section)

How often do you feel happy? Do you feel sad, depressed, or miserable? Are you happy and satisfied with your life at present? Do you feel lonely lately? How do you feel about your future? Do you sometimes feel that life is not worth living? Do you feel tense and do you worry more than usual? Do you consider yourself a nervous person? Do you feel worthless?
