ABSTRACT The growing diversity of the population of the United States and the high burden of cancer-related symptoms reflect the need for caregiver research within underserved groups. In this longitudinal study, the authors assessed changes in symptom severity in caregivers and underserved minority patients diagnosed with advanced solid tumors who were being treated at public hospitals.
A total of 85 matched patient-caregiver dyads completed the M. D. Anderson Symptom Inventory 3 times during 20 weeks of chemotherapy. At each time point, symptom severity and interference with daily activities were assessed. Group-based trajectory modeling was used to classify caregivers into high-symptom or low-symptom burden groups.
Sadness and distress were more prevalent among caregivers (P = .005). Symptom burden remained stable among caregivers in the high-symptom group (40%), whereas the low-symptom group (60%) demonstrated a statistically significant decrease over time. Multivariate analysis found being a family-member caregiver (adjusted odds ratio [ADJ-OR], 4.1; 95% confidence interval [95% CI], 1.4-11.6) and caring for a highly symptomatic patient (ADJ-OR, 8.0; 95% CI, 1.5-41.4), rather than race, ethnicity, or sociodemographic characteristics, were significant predictors of the caregiver's membership in the high-symptom burden group.
Approximately 40% of the caregivers in the current study were found to be at an increased risk for moderate to severe sadness and distress, which remained severe throughout the patient's treatment course at public hospitals. To the authors' knowledge, this study marks the first time that the concept of symptom burden has been used to measure caregiver burden, and the first time that symptom burden has been measured and documented in dyads of caregivers and underserved minority patients.

    ABSTRACT: To examine the patient and family caregiver variables that predicted caregiver burden and depression for family caregivers of patients with cancer at the end of life. A prospective, longitudinal study was implemented with an inception cohort of patients and their family caregivers who were followed after the diagnosis and treatment of cancer. Community oncology sites in the midwestern United States. 152 family caregivers of patients with cancer who died during the course of the study. Telephone interviews were conducted with patients at 6-8, 12-16, 24-30, and 52 weeks following diagnoses. In addition, patient medical records and state death certificates were reviewed. Effect of caregiver age, gender, education, relationship to the patient, employment status, reports of patient symptoms, patient cancer type, stage of cancer, time from the patient's diagnosis to death, caregiver burden, and depression. Caregivers aged 45-54 reported the highest levels of depressive symptoms, and caregivers aged 35-44 reported the strongest sense of abandonment. Caregivers who were the adult children of patients with cancer and those who were employed reported high levels of depressive symptoms. Feeling abandoned (a portion of caregiver burden) was more prevalent in female, nonspouse, and adult children caregivers, and adult children caregivers of patients with early-stage cancer and patients with multiple symptoms reported a high perception of disruption in their schedule because of providing care. Caregivers whose patients died early following diagnosis reported the highest depressive symptoms, burden, and impact on schedule. Caregivers reported levels of depression at thresholds for screening of clinical depression. The number of patient symptoms was related to levels of caregiver depressive symptoms. An association also was found between depression and employment status. Caregiver distress was not dependent on demands of care. Very little research exists that prospectively analyzes family caregiver experiences of burden and depression when providing end-of-life cancer care for a family member. Interventions aimed at decreasing caregiver depressive symptoms should be targeted to caregivers who are middle-aged, adult children, and employed. Interventions aimed at decreasing the burden associated with feeling abandoned and having schedules disrupted while providing care should be targeted to caregivers who are female, nonspouse, and adult children, and caregivers of patients with early-stage cancer and multiple symptoms.

    ABSTRACT: Much research has documented both negative emotional and physical health conditions that may result from providing care to a family member with an illness. However, little has been done in family caregiving, particularly in oncology, to evaluate pathways in which biological and behavioral responses to stress may interact. The purpose of this article is to describe how a mind-body (biobehavioral) model can be adapted to study family caregivers of persons with a brain tumor. A systematic literature review was performed on caregiving literature in the area of dementia and oncology to provide support for proposed relationships in the model. Prior research supports the application of a biobehavioral model to family caregiving in neuro-oncology and suggests ways in which emotional reactions to caregiving may be manifested as changes in physical health. Suggestions for conducting biobehavioral research in oncology caregiving and alternative variables for future research are presented.
