The hypothesis that personality characteristics in adolescence can be used to predict religiousness and spiritual seeking in late adulthood was tested using a structural equation modeling framework to estimate cross-lagged and autoregressive effects in a two-wave panel design. The sample consisted of 209 men and women participants in the Berkeley Guidance and Oakland Growth studies. In late adulthood, religiousness was positively related to Conscientiousness and Agreeableness, and spiritual seeking was related to Openness to Experience. Longitudinal models indicated that Conscientiousness in adolescence significantly predicted religiousness in late adulthood above and beyond adolescent religiousness. Similarly, Openness in adolescence predicted spiritual seeking in late adulthood. The converse effect, adolescent religiousness to personality in late adulthood, was not significant in either model. Among women, adolescent Agreeableness predicted late-life religiousness and adolescent religiousness predicted late-life Agreeableness; both these effects were absent among men. Adolescent personality appears to shape late-life religiousness and spiritual seeking independent of early religious socialization.

This study used longitudinal data to examine the relations among religiousness, spirituality, and 3 key domains of psychosocial functioning in late adulthood: (a) sources of well-being, (b) involvement in tasks of everyday life, and (c) generativity and wisdom. Religiousness and spirituality were operationalized as distinct but overlapping dimensions of individual difference. In late adulthood, religiousness was positively related to well-being from positive relations with others, involvement in social and community life tasks, and generativity. Spirituality was positively related to well-being from personal growth, involvement in creative and knowledge-building life tasks, and wisdom. Neither religiousness nor spirituality was associated with narcissism. The relations between religiousness, spirituality, and outcomes in late adulthood were also observed using religiousness scored in early and spirituality scored in late middle adulthood. All analyses were controlled for gender, cohort, social class, and the overlap between religiousness and spirituality.

This article examines the relations between religiousness, spirituality, and generativity (concern for the welfare of future generations) in late adulthood using longitudinal life-course data. Religiousness and spirituality were operationalized as distinct but overlapping dimensions of individual difference measuring involvement in traditional and nontraditional religious practices, respectively. In late adulthood, both religiousness and spirituality correlated positively with overall scores on self-report and observer-based measures of generativity. However, whereas religiousness was significantly related to the communal facets of generativity, spirituality was significantly related to its self-expanding aspects. These differences were more pronounced after gender, cohort, social class, and the overlap between religiousness and spirituality were controlled. The respective relations among religiousness, spirituality, and generativity in late adulthood were also observed using religiousness scored in early, and spirituality scored in late-middle, adulthood.
