An application of multiple discrepancies theory (MDT) to seniors

Items of the Affect Balance Scale, the Life Satisfaction Index-Z and the Philadelphia Geriatric Center Scale together with 22 new items were used in the construction of a happiness scale for the elderly. Items were initially administered to 301 subjects from urban, rural, and institutional settings and correlated with ratings of happiness. A new scale consisting of 24 items was cross-validated on an additional 297 subjects. Test-retest reliability scores were obtained on 56 subjects. Results indicated that the new scale was a better predictor of "avowed happiness" in both validation and cross-validation samples than the existing scales used for comparison. Moreover, the new scale's test-rated reliability was within an acceptable range for this type of scale.
