Factors Associated with Anxiety and Depression among Family Caregivers of Patients Undergoing Palliative Radiotherapy

Abstract

Objective: The family caregivers of patients receiving palliative care experience high levels of anxiety and depression. The aim of the present study was to investigate the factors associated with family caregivers’ anxiety and depression when caring for patients with advanced cancer in Greece. Methods: The sample consisted of 100 patients undergoing palliative radiotherapy and their respective caregivers. Patients completed the Hospital Anxiety and Depression Scale (HADS) and the MD Anderson Symptom Inventory. Their respective caregivers completed the Oberst Caregiving Burden Scale, the Bakas Caregiving Outcomes Scale, and the HADS. Correlational and multiple regression analyses were conducted to identify potential predictors of anxiety and depression. Results: The majority of patients were male (63.0%), whereas the majority of their caregivers were female (76.0%). The mean ages of patients and caregivers were 63.9 ± 10.8 and 53.3 ± 12.6 years, respectively. Caregiving anxiety and depression were associated with patients’ variables, such as gender ( P < 0.0005), primary cancer ( P = 0.008), and past surgery ( P = 0.002), and caregiver's variables, such as gender ( P = 0.001), co-residence ( P = 0.05), previous care experience ( P = 0.04), and means of transport ( P = 0.038). In multiple regression analyses, caregiving anxiety and depression were significantly predicted by caregivers’ and patients’ characteristics, in a model that accounted for 48% of the anxiety variance ( P < 0.0005) and 39% of the depression variance ( P < 0.0005). Conclusion: The caregivers who experienced more anxiety and depression shared the following traits: they were women, cared for men with lung cancer, cared for patients not undergoing surgery, lived together, were younger, went to the hospital by private means of transport, had previous care experience, and perceived an increased degree of general burden. Further investigation of the factors that may affect caregivers’ psychological state is required to better identify parameters that may predict it.

Determinants of Health Promotion Behaviors among Family Caregivers of Stroke Survivors

“…Social support is the strongest positive predictor of health promotion and has a positive effect on caregivers’ quality of life [ 43 ]. In Greece, social support is greater than in some other countries [ 44 ], because of the strong ties that exist between members even of the extended family [ 45 ]. It is generally accepted worldwide that the family consists of a group of individuals who are connected to each other by powerful emotional bonds and their own unique cultural perceptions that influence their health [ 46 ].…”

Assessment of Anxiety and Depression and its Association with Socio-demographic Characteristics among Family Caretakers of Cancer Patients

“…Alternatively the option of surgery can minimize the psychological symptoms and morbidity. 22 The inconsistent outcomes were also scripted. 17 Two studies exposed the psychological injurious effects of chemo and radiotherapy upon the family caregivers.…”

Application of doctor-patient communication skills in clinical teaching of postgraduates of tumour radiotherapy

“…Cancer patients and their families often endure the torture of the disease, pain of treatment, and high cost of medical treatment. However, they must face heavy blows, such as tumour recurrence, metastasis, and disease progression, which often cause great psychological pressure [5]. On the one hand, due to the lack of understanding of malignant tumours, patients have a strong psychological dependence on doctors.…”
