OBJECTIVES: To examine the effect of informal cancer caregiving and repetitive negative thinking (RNT) on depressive symptoms and salivary cortisol levels. SAMPLE & SETTING: The sample was recruited from a hospital bone marrow unit and caregiver support organizations. It included 60 informal cancer caregivers (52% partners) of individuals with cancer who provided care for a median of 27.5 hours per week for 12 months, and 46 noncaregiver participants.

Setting: Bone marrow unit at the University of Louisville Hospital in Kentucky and caregiver support organizations in Louisville. Sample: 49 current cancer caregivers who were primarily spouses or partners of individuals with lymphoma or leukemia and provided care for a median of 30 hours each week for 12 months.
