The Depression-Happiness Scale: test-retest data over two weeks.
The present aim was to examine further the psychometric properties of the Depression-Happiness Scale. Test-retest data over 2 wk. are reported for this scale for a sample of 54 female Northern Irish university students. Stability was fairly high as r = .70, and there was no significant change between Time 1 and Time 2 (M = 49.7 and 50.8, respectively). The data suggest that the Depression-Happiness Scale might be considered a trait measure of happiness rather than a state measure.
