- Three-item index:
1. 'I felt that everything I did was an effort.'
2. 'I did not feel like eating; my appetite was poor.'
3. 'My sleep was restless.
Subjects were asked for each item to indicate how often they felt this way during the past week; 1: rarely or none of the time, 2: some or a little of the time, 3: occasionally or a moderate amount of time, 4: most or all of the time.
These categories were recoded in: rarely experiencing depressed affect (1), occasionally experiencing depressed affect (2+3), frequently experiencing depressed affect (4).
Items are drawn from the 20-item CES-D scale of depressive symptomatology (Comstock & Helsing, 1976; Radloff, 1977).
