title: Prevalence and predictors of anxiety and depression among family caregivers of cancer patients: a nationwide survey of patient-family caregiver dyads in Korea.
abstract: OBJECTIVE
  This study aimed to identify the prevalence and predictors of anxiety and depression among family caregivers of patients with cancer in Korea.
  
  
  METHODS
  A 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.
  
  
  RESULTS
  The 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.
  
  
  CONCLUSIONS
  Family 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.
