To date, a comprehensive, psychometrically robust instrument to assess palliative and end-of-life (PEOL) care education, practice, and perceived competence among intensive care unit (ICU) nurses does not exist.
To examine content validity and reliability of a proposed instrument to assess the PEOL care education-practice- competence triad among ICU nurses.
An international modified e-Delphi and a cross-sectional pilot questionnaire survey. The Delphi involved 23 panelists from 11 countries. The pilot study involved 40 staff nurses and 3 nurse managers from 3 adult ICUs in a randomly selected hospital in Egypt. An instrument was developed and judged for content validity by international panelists, and then pretested in a pilot study, where data were collected at 2 time points using self-administered questionnaires, followed by cognitive interviews. Test-retest reliability was examined using intraclass correlation (ICC), standard error of measurement (SEM), and repeatability coefficient (RC).
The panelists confirmed content validity of the proposed instrument, and staff nurses confirmed its comprehensibility. At the level of the instrument's total scores, the lowest ICC was .9 (95% confidence interval: .8-.9); and the highest SEM and RC were 4.8 and 13.3, respectively.
The PEOL Care Index is a comprehensive, comprehensible, content valid, and reliable instrument to assess the PEOL care education-practice-competence triad among ICU nurses. Construct and criterion validities need to be confirmed in future studies. Applicability of the PEOL Care Index in different settings and cultures needs to be examined.
迄今为止，尚无综合、心理测量学稳健的工具来评估重症监护病房（ICU）护士的姑息治疗和临终关怀（PEOL）护理教育、实践和感知能力。
检验评估 ICU 护士 PEOL 护理教育-实践-能力三合一体的拟议工具的内容效度和信度。
采用国际改良电子德尔菲法和横断面预试验问卷调查。德尔菲法涉及来自 11 个国家的 23 名小组成员。预试验涉及在埃及随机选择的一家医院的 3 个成人 ICU 的 40 名在职护士和 3 名护士长。开发了一种工具，由国际小组成员对其内容效度进行评估，然后在预试验中进行预测试，在预试验中，使用自我管理问卷在 2 个时间点收集数据，然后进行认知访谈。使用组内相关系数（ICC）、测量标准误差（SEM）和可重复性系数（RC）评估测试-重测信度。
小组成员确认了拟议工具的内容效度，在职护士确认了其可理解性。在工具总分方面，最低 ICC 为.9（95%置信区间：.8-.9）；最高 SEM 和 RC 分别为 4.8 和 13.3。
PEOL 护理指数是一种综合、可理解、内容有效的工具，可用于评估 ICU 护士的 PEOL 护理教育-实践-能力三合一体。未来的研究需要确认构念和效标效度。需要在不同的环境和文化中检验 PEOL 护理指数的适用性。
