The crisis of cancer: psychological impact on family caregivers.

Cancer causes changes in the family's identity, roles, and daily functioning. Studies document that spouses are as distressed as cancer patients and that spousal and patient distress are correlated. Three major areas of caregiver concern are: fear of cancer and its spread, helping patients deal with the emotional ramifications of the disease, and managing the disruptions caused by cancer. From 20% to 30% of partners suffer from psychological impairment and mood disturbance as a result of the spouse's cancer. Factors that may predict high levels of spousal distress include: disease stage; emotional adjustment of the patient; gender, age, and other characteristics of the spouse; marital adjustment; and family functioning. Studies show that interventions do not reduce spousal distress. Future studies should explore the role of mediating factors, such as coping style, marital adjustment, and family functioning, on the relationship between illness demands or prognosis and distress. Interventions could then be targeted to high-risk individuals.
