Aging and altruism: A meta-analysis.

Life span theories postulate that altruistic tendencies increase in adult development, but the mechanisms and moderators of age-related differences in altruism are poorly understood. In particular, it is unclear to what extent age differences in altruism reflect age differences in altruistic motivation, in resources such as education and income, or in socially desirable responding. This meta-analysis combined 16 studies assessing altruism in younger and older adults (N = 1,581). As expected, results revealed an age-related difference in altruism (Mg = 0.61, p < .001), with older adults showing greater altruism than younger adults. Demographic moderators (income, education, sex distribution) did not significantly moderate this effect, nor did aspects of the study methodology that may drive socially desirable responding. However, the age effect was moderated by the average age of the older sample, such that studies with young-old samples showed a larger age effect than studies with old-old samples. These findings are consistent with the theoretical prediction of age-related increases in altruistic motivation, but they also suggest a role for resources (e.g., physical, cognitive, social) that may decline in advanced old age.
