The current study examines constructs that contribute to the well-being of an international sample of older married adults. A convenience sample of 208 participants was recruited through an Internet site as well as more traditional means such as newspaper advertisements and contact with community groups. The resulting structural equation model provides further support for the revised theory of cognitive adaptation. Within this model, the direct and indirect contributions of personality, marital satisfaction, and cognitive adaptation are examined in relation to well-being. Contrary to previous findings, personality appears to have an indirect effect upon both marital satisfaction and well-being. Cognitive adaptation, in contrast, has both a direct and indirect effect upon the well-being of older adults. Limitations of use of the Internet as a vehicle for data collection are considered as well as directions for future study.
