assessing the correct understanding of families about the occurrence of marital cancer (statistical population: denmark, sweden and iran)

In this descriptive-correlational study, 1854 couples with cancer participated in inpatient wards in denmark, sweden and iran. to collect the data, a family performance questionnaire was used, assessing the performance of families in the dimensions of problem solving, communication, maps, emotional companionship, emotional association, behavior control and overall performance. all couples participating in this study reported their family performance in all relatively appropriate dimensions. there was a statistically significant relationship between the patients' views on overall family functioning and age of marriage and the age of the eldest child. although the family functioning of cancer patients is relatively good, more attention should be paid to counseling services for the family and their family members. as the family is the primary source of care and support for cancer patients. in general, the need to consider the whole family unit as a client is one of the necessities of providing nursing care and family-centered support for cancer patients.
