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.

癌症姑息治疗患者生存压力量表的开发与心理测试
目的:存在性痛苦是姑息治疗癌症患者的一种常见现象。为癌症姑息治疗患者制定一个可靠且易于使用的存在性痛苦评估量表至关重要。本研究的目的是为癌症姑息治疗患者开发一种存在性痛苦测量方法,并测试其特性:方法:遵循德韦利斯(DeVellis)提出的量表编制指南。邀请癌症姑息治疗患者对量表草案进行测试。共有 219 份有效问卷被纳入项目分析和探索性因子分析。三百零二份有效问卷被纳入确认性因子分析、收敛效度分析、判别效度分析和内部一致性信度分析。对 20 份重复数据进行了重测信度分析:结果:编制了癌症姑息治疗患者存在性苦恼量表,包括无意义感、疏离感和死亡焦虑三个维度的九个项目。确认性因素分析表明,所编制的量表具有稳定的因素结构。整个量表的 Cronbach's α 为 0.81,各维度的 Cronbach's α 分别为 0.76、0.67 和 0.70。量表的重测信度为 0.79,各维度的重测信度为 0.58-0.64:癌症姑息治疗患者存在性苦恼量表是一个简单但可靠有效的工具。

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.
