We adapt resource theory to compare involvement in family decisions by older women and men in the more patriarchal setting of Egypt and the more egalitarian setting of Tunisia. Data from the World Health Organization Collaborative Study on Social and Health Aspects of Aging are analyzed. In Egypt, women participate less often than men in most decisions, whereas participation is more gender equitable in Tunisia. Increasing age and declining health are negatively associated with participation in daily and life course decisions, particularly for Egyptian women. Although women participate less often than men in life course decisions in Egypt, involvement is more frequent among widows and those owning their homes. Future research should examine the relationship of resources, support, and the family power of older adults across normative contexts.
