Prevalence and predictors of anxiety and depression among family caregivers of cancer patients: a nationwide survey of patient-family caregiver dyads in Korea

Abstract

PurposeThis study aimed to identify the prevalence and predictors of anxiety and depression among family caregivers of patients with cancer in Korea.MethodsA national, multicenter, cross-sectional survey was conducted with 897 family caregivers. The Hospital Anxiety and Depression Scale was used to assess anxiety and depression in patient?family caregiver dyads.ResultsThe prevalence of anxiety in family caregivers was 38.1 %:20.3 % reported mild anxiety, 13.3 % reported moderate anxiety, and 4.6 % reported severe anxiety. The prevalence of depression was 82.2 %:40.4 % reported mild depression, 25.5 % reported moderate depression, and 16.3 % reported severe depression. Family caregivers who were younger, were caring for male patients, or had a low quality of life (QOL) in relation to three of the variables measured in the Korean Caregiver Quality of Life Index-Cancer (CQOLC-K): burden, disturbance, and financial concerns reported increased anxiety. Becoming unemployed during caregiving, being the spouse of a patient and having low QOL in relation to three of the variables measured by the CQOLC-K: burden, disturbance, and positive adaptation were associated with depression among family caregivers. The predictive validity of the selected variables were 0.861 (95 % CI: 0.844?0.892) for anxiety and 0.794 (95 % CI: 0.751?0.828) for depression.ConclusionsFamily caregivers of patients with cancer experienced high levels of anxiety and depression. Socio-demographic factors and QOL were predictors of anxiety and depression in family caregivers.
