Relationships with family members have been shown to be important in old age, both with adult children and with elderly siblings. Through shared memories such relationships may help with the life review (a process in which there is a detailed reconsideration and evaluation of personal experiences throughout life). To compare the differences in patterns of reminiscence between elderly siblings, and between elderly adults and their children, 127 parent-child and 93 sibling relationships were studied using in-home interviews. Analyses of results confirmed that reminiscence about old times was significantly greater in sibling relationships. In parent-child communication, other family members were the most frequent topic of discussion, followed by the parent's health. Results also showed that sibling reminiscence was greater, the fewer the number of living siblings remaining in the family. The findings suggest that reminiscence can be used to clarify and validate past events, resolve conflict, and diminish rivalry. (JAC)
