Abstract
The literature on age differences in life satisfaction, self-concept, and locus of control reveals a variety of conflicting findings. Nehrke et al. reported a study of elderly institutionalized males that attempted to control for some of the possible sources of variability [1]. The present study extended this effort to a noninstitutionalized life-span sample of males and females in six age groups (fourteen to ninety-four). The age main effect was significant for the locus of control measure. For self-concept, the age and sex main effects were significant. For life satisfaction, the age and sex main effects and their interaction were significant. Generally, lower levels of self-concept and life satisfaction and a more external orientation characterized adolescents and young adults while, with notable exceptions, the remaining age samples were more positive in self-concept and life satisfaction and were more internally controlled. Although the three dependent measures were significantly correlated for the total sample, the correlations involving locus of control were only moderate. The data suggest that at least the life satisfaction and self-concept measures may be viable tools to assess the psychological quality of one's life, and that reliable age differences in well-being can be demonstrated if moderating variables are controlled experimentally or statistically.
