Description
Summary:The goal of palliative care is to maximize the quality of life and thus maintain the dignity of patients facing problems associated with a life-threatening illness. The Patient Dignity Inventory (PDI) is an instrument used to measure various sources of distress that can impact patients’ sense of dignity at the end of life. We aimed to obtain a Korean translation of the PDI (PDI-K) and evaluate its psychometric properties in patients with advanced cancer. Translation and cultural adaptation of the PDI were performed to obtain the Korean version. In a sample of 131 inpatients and outpatients with advanced cancer, psychometric properties, including factor structure, internal consistency, and concurrent validity, were examined. Concurrent validity was evaluated using the Edmonton Symptom Assessment System, the Hospital Anxiety and Depression Scale, and the 12-item Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being. Cronbach's α for the PDI-K was 0.96. Four factors were identified by exploratory factor analysis, accounting for 68.7% of the overall variance: Dependency and Physical Symptoms, Psychological Distress, Existential Distress, and SocialSupport. Concurrent validity was confirmed by significant correlations between PDI-K and Edmonton Symptom Assessment System (r = 0.40 to 0.59, P
