Abstract
Objective: Existential distress is a common phenomenon in palliative care cancer patients. Developing a reliable and easy-to-use assessment scale for existential distress of palliative care cancer patients is crucial. The aim of this study was to develop a measurement of existential distress for palliative care cancer patients and test its properties.
Methods: The guidelines for developing a scale proposed by DeVellis were followed. Palliative care cancer patients were invited to test the draft scale. Two-hundred and nineteen valid questionnaires were included for the item analysis and exploratory factor analysis. Three-hundred and two valid questionnaires were included for confirmatory factor, convergent validity, discriminant validity, and internal consistency reliability analyses. Twenty repeated data were measured for test-retest reliability analysis.
Results: The Existential Distress Scale for Palliative Care Cancer Patients was developed with nine items and three dimensions, including meaninglessness, alienation, and death anxiety. The confirmatory factor analysis showed that the developed scale had a stable factor structure. The Cronbach's α for the whole scale was 0.81, and that for each dimension was 0.76, 0.67, and 0.70, respectively. The test-retest reliability of the scale was 0.79, and that of each dimension was 0.58-0.64.
Conclusions: The Existential Distress Scale for Palliative Care Cancer Patients is a simple but reliable and valid tool.
期刊介绍：
Psycho-Oncology is concerned with the psychological, social, behavioral, and ethical aspects of cancer. This subspeciality addresses the two major psychological dimensions of cancer: the psychological responses of patients to cancer at all stages of the disease, and that of their families and caretakers; and the psychological, behavioral and social factors that may influence the disease process. Psycho-oncology is an area of multi-disciplinary interest and has boundaries with the major specialities in oncology: the clinical disciplines (surgery, medicine, pediatrics, radiotherapy), epidemiology, immunology, endocrinology, biology, pathology, bioethics, palliative care, rehabilitation medicine, clinical trials research and decision making, as well as psychiatry and psychology.
This international journal is published twelve times a year and will consider contributions to research of clinical and theoretical interest. Topics covered are wide-ranging and relate to the psychosocial aspects of cancer and AIDS-related tumors, including: epidemiology, quality of life, palliative and supportive care, psychiatry, psychology, sociology, social work, nursing and educational issues.
Special reviews are offered from time to time. There is a section reviewing recently published books. A society news section is available for the dissemination of information relating to meetings, conferences and other society-related topics. Summary proceedings of important national and international symposia falling within the aims of the journal are presented.
