Purpose: Caregivers face severe difficulties in communicating openly with their terminally ill relatives about illness and death. Some studies suggest that females are more likely than males to hold such conversations. We compared level of open communication between male and female spouse-caregivers, and the contribution of personal and situational characteristics to the explanation of open communication level within each gender group. Methods: The study design was correlational. We interviewed 77 spousal-primary caregivers of terminal cancer patients.
