Mean Trends for Depression Items
Note. Longitudinal means for each of the five items in the NLSY97 depression scale. Items “Calm” and “Happy” were found to load on the positive factor, while items “Nervous”, “Down” and “Depressed” loaded on the negative factor. All items were scored on a 4-point Likert scale, and the two positive items were reverse-scored so that increases in item means indicated increased depression.
