BACKGROUND
In recent years, one of the concepts that has received attention in the nursing profession is professional dignity. On the other hand, there was no proper scale to evaluate this concept. This study aimed to develop and evaluate the psychometric properties of perceived clinical nurses' professional dignity scale (PCNPDS).
METHODS
This exploratory sequential mixed method was developed and implemented in Iran. The study was conducted in two phases; (a) item generation by hybrid concept analysis and (b) item reduction by psychometric evaluation including validity and reliability of the developed scale. Also, the interpretability (ceiling and floor effect), stability (intraclass correlation coefficient), and absolute stability (standard error of measurement) were calculated.
RESULTS
68 items in the primary item pool were finally reduced to 22 items after evaluating the validity (face, content, and construct validity) and reliability. Exploratory factor analysis revealed three factors (organizational dignity, dignity-based competency, and dignity-based appreciation) and explained 47.55% of the total extracted variance. Confirmatory factor analysis showed that the model had a good fit. Finally, Cronbach's alpha coefficient, McDonald's omega, ICC, and SEM were calculated as 0.90, 0.89, 0.96, and 1.91, respectively.
CONCLUSION
The 22-item developed scale is valid and reliable for professional dignity measurement among Iranian clinical nurses.
背景
近年来，职业尊严是护理行业中受到关注的概念之一。另一方面，尚无合适的量表来评估这一概念。本研究旨在编制并评估护士职业尊严感知量表（PCNPDS）的心理测量特性。
方法
本探索性序贯混合方法在伊朗开展并实施。研究分两个阶段进行：（a）通过混合概念分析生成条目；（b）通过心理测量评估（包括所编制量表的效度和信度）减少条目。此外，还计算了可解释性（天花板效应和地板效应）、稳定性（组内相关系数）和绝对稳定性（测量标准误）。
结果
在评估效度（表面效度、内容效度和结构效度）和信度后，初始条目池中的68个条目最终缩减至22个。探索性因子分析揭示了三个因子（组织尊严、基于尊严的能力和基于尊严的赞赏），解释了总提取方差的47.55%。验证性因子分析表明模型拟合良好。最后，计算得到Cronbach's α系数、McDonald's ω系数、组内相关系数和测量标准误分别为0.90、0.89、0.96和1.91。
结论
所编制的22个条目的量表对于测量伊朗临床护士的职业尊严是有效且可靠的。
