Evaluating professional values is crucial to developing effective strategies for integrating them into professional performance and clinical education. A standard questionnaire is an instrument that can be used to evaluate professional values. This study aimed to assess the validity and reliability of the Nurses Professional Values Scale-Revised (NPVS-R) among nursing students in the Persian language.
This methodological and cross-sectional study aimed to evaluate the validity and reliability of the Persian version of the NPVS-R among nursing students. Following a back-translation process, the Persian version was subjected to face, content, and construct validity assessments. Construct validity was examined using exploratory factor analysis (EFA) on a sample of 439 nursing students during their internships at 16 public universities of medical sciences in Iran between April and July 2019. Additionally, convergent and divergent validity were assessed on a separate sample of 105 nursing students. The reliability of the instrument was assessed using both internal consistency measures and the test-retest method. Furthermore, the psychometric properties of the questionnaire were analyzed using Samejima's Gradual Response Model. Data analysis was performed using SPSS (version 19) and MPLUS (version 5.1).
All components had a content validity ratio greater than 0.6 and a content validity index of 1, indicating excellent content validity. Exploratory factor analysis reduced the items to 25, with five factors explaining 52.26% of the variance. The scale exhibited strong convergent validity (r = 0.73, p < 0.001) and satisfactory divergent validity (r = 0.12, p = 0.21; r = 0.07, p = 0.47). Test-retest reliability was excellent, with an intraclass correlation coefficient (ICC) of 0.92. Cronbach's alpha coefficients ranged from 0.53 to 0.83 for the factors and 0.91 for the entire scale, showing good internal consistency. IRT analysis confirmed that alpha parameters for all items were statistically significant and at an acceptable level. Thus, the Persian NPVS-R, with 25 items and 5 factors, is a valid and reliable tool for nursing students.
The Persian NPVS-R, comprising 25 items and 5 factors, demonstrated excellent validity and reliability. This scale serves as a standardized tool for evaluating the professional values of nursing students, suitable for application in educational and clinical settings to enhance nursing practice and education.
评估专业价值观对于制定将其融入专业表现和临床教育的有效策略至关重要。标准问卷是一种可用于评估专业价值观的工具。本研究旨在评估波斯语版护士专业价值观量表修订版（NPVS-R）在护理专业学生中的有效性和可靠性。
本方法学横断面研究旨在评估波斯语版NPVS-R在护理专业学生中的有效性和可靠性。经过回译过程后，对波斯语版进行了表面效度、内容效度和结构效度评估。在2019年4月至7月期间，对伊朗16所医科大学实习的439名护理专业学生样本进行探索性因素分析（EFA），以检验结构效度。此外，对105名护理专业学生的另一个样本进行了聚合效度和区分效度评估。使用内部一致性测量和重测法评估该工具的可靠性。此外，使用Samejima的渐进反应模型分析问卷的心理测量特性。使用SPSS（版本19）和MPLUS（版本5.1）进行数据分析。
所有分量表的内容效度比均大于0.6，内容效度指数为1，表明具有出色的内容效度。探索性因素分析将项目减少到25个，五个因素解释了52.26%的方差。该量表表现出较强的聚合效度（r = 0.73，p < 0.001）和令人满意的区分效度（r = 0.12，p = 0.21；r = 0.07，p = 0.47）。重测信度极佳，组内相关系数（ICC）为0.92。各因素的Cronbach's alpha系数在0.53至0.83之间，整个量表为0.91，显示出良好的内部一致性。IRT分析证实所有项目的alpha参数在统计学上具有显著性且处于可接受水平。因此，包含25个项目和5个因素的波斯语NPVS-R是护理专业学生的有效且可靠的工具。
包含25个项目和5个因素的波斯语NPVS-R表现出出色的有效性和可靠性。该量表是评估护理专业学生专业价值观的标准化工具，适用于教育和临床环境，以加强护理实践和教育。
