In order to improve the provision of palliative care by nurses, it is necessary to have a tool that measures different dimensions of palliative care and the knowledge and performance of nurses in this field. The Program in Palliative Care Education and Practice Questionnaire (German Revised) is psychometrically evaluated for the first time in Iran.
To measure the psychometric properties, 360 nursing students (BSc, MSc, PhD) and clinical nurses completed the questionnaire. Face and content (CVR and CVI) validity were checked by quantitative and qualitative approach. Construct validity was performed with exploratory and confirmatory factor analysis. The total variance explained was equal to 43%; the internal consistency reported a Cronbach's alpha of more than 0.7; and the composite reliability was greater than 0.7.
After conducting construct validity and factor analysis, four factors (Knowledge and skill of managing patients' pain and symptoms, management of ethical and psychological issues in patients, communicating with patients and their families & management of patients' exposure to grief and attitudes towards death) were extracted. The total variance was equal to (%43) and coefficients of internal consistency were estimated more than 0.7. Also composite reliability was evaluated greater than 0.7.
Persian version of the Program in Palliative Care Education and Practice Questionnaire (German Revised Version; PPCEP-GR) is a valid and reliable questionnaire that can be used to measure the knowledge and performance of nurses and nursing graduates in the field of palliative care.
为了提高护士提供姑息治疗的水平，有必要开发一种工具来衡量姑息治疗的不同维度以及护士在这一领域的知识和技能。本研究首次在伊朗对姑息治疗教育和实践计划问卷（德语修订版）进行心理测量学评估。
为了测量心理测量学特性，360 名护理学生（本科、硕士、博士）和临床护士完成了问卷。通过定量和定性方法检查了表面效度和内容效度（内容效度比和内容效度指数）。通过探索性和验证性因子分析进行了结构效度检验。总方差解释率等于 43%；内部一致性报告的克朗巴赫α系数大于 0.7；综合可靠性大于 0.7。
在进行结构有效性和因子分析后，提取出四个因子（管理患者疼痛和症状的知识和技能、管理患者的伦理和心理问题、与患者及其家属沟通和管理患者对悲伤的暴露以及对死亡的态度）。总方差等于（43%），内部一致性系数估计大于 0.7。综合可靠性也大于 0.7。
姑息治疗教育和实践计划问卷（德语修订版；PPCEP-GR）的波斯语版本是一种有效的、可靠的问卷，可用于衡量姑息治疗领域护士和护理毕业生的知识和技能。
