Research has begun to define the older adult population, not as a homogeneous sample, but as at least two groups with different concerns. To determine the factors contributing to retirement satisfaction, two groups of retirees, i.e., young-olds, aged 75 and under (N=49) and old-olds, over age 75 (N=49), completed the Individual Status Assessment Questionnaire (ISAQ) and the Retirement Descriptive Index (RDI). Subjects were compared using ISAQ subscales of health, morale, values, value orientation, leisure, social relationships, wealth, prior work satisfaction, mobility, and retirement reason, and RDI scales of activities, finances, health, and people. A discriminant analysis using all ISAQ scales and the RDI found age differences in leisure, health, morale, and overall satisfaction. The ISAQ subscales were used as predictors of retirement satisfaction based on the RDI. Significant regression equations predicting the four RDI satisfaction scales differed for the two age groups. Few differences were found between the two groups on the component dimensions of the ISAQ. Differences which emerged in the discriminant analysis and the regression analyses were in the weighting and patterns of dimensions which discriminated between the two groups or predicted satisfaction in the two groups. The findings suggest that the dimensions of satisfaction during retirement contribute differentially for the two groups. (Author/NRB)
