Contextual and stress process factors associated with head and neck cancer caregivers' physical and psychological well-being.

Head and neck cancer (HNC) caregivers are especially vulnerable to poor outcomes because the HNC patients are at high risk for physical and functional impairments. This study examines contextual and stress process variables potentially associated with HNC caregivers' physical and psychological well-being. Patient-caregiver variables included socio-demographics, primary stressors (caregiving, patient clinical characteristics, HNC-related symptoms/dysfunction), secondary stressors (caregiver employment, childcare responsibilities and sleep duration <7 hr), appraisal, and response (physical activity). General linear models modeled caregiver well-being, along with depression and anxiety. A total of 33 patient-caregiver dyads were included. Most caregivers were female (81.8%) and patient spouses/partners (72.7%). Factors significantly associated with better caregiver physical well-being included caregiver older age, <2 comorbidities, ≥7 hr of sleep, ≥3 days/week physical activity, and patient swallowing and speech dysfunction. Factors significantly associated with better caregiver mental health functioning were less patient social dysfunction and less perceived caregiving burden. Short nighttime sleep, higher caregiver burden, and <3 days/week physical activity were also significantly related to caregivers' depression and anxiety. Results suggested caregiver behaviors and perceived burden, along with patient HNC concerns are linked with caregiver well-being. These behavioral, cognitive, and patient factors should be incorporated into caregiver screening tools or targeted with behavioral interventions to improve caregiver well-being.
