This study was designed to assess the content and construct validity and reliability of the Quality of Nursing Doctoral Education (QNDE) instrument for nursing doctoral programmes with a research focus.
A cross-sectional, survey study.
Using Qualtrics survey, the research team sent emails to potential participants providing a link to the study and the QNDE instrument.
A total of 234 faculty and doctoral students participated: 17 faculty from 14 countries in the first stage; 111 faculty and 106 doctoral students from 20 countries in the second stage.
The content validity, internal consistency reliability, and construct validity of the four domains (program, faculty, resources, and evaluation) of the QNDE were examined in two stages. Data were collected from purposive samples of faculty and students between June 2018 and March 2019. Confirmatory factor analysis was conducted in ordinal scale using robust weighted least square mean and variance (WLSMV) adjusted estimator in MPlus 8.
Content validity of the items in the four domains was accepted when the item showed content validity (I-CVI > 0.78). Internal consistency reliability in four domains was computed using Cronbach's alpha, α = 0.88 to 0.97. Construct validity of the QNDE was established by confirmatory factor analysis based on model fit statistics. Factor loading coefficients for all items in each domain were statistically significant (>0.5; p < .001).
Participation of 234 faculty and doctoral students from 20 countries on four continents confirmed content validity, internal consistency reliability, and construct validity of the QNDE instrument. These findings support the credibility of this revised QNDE instrument for assessing the quality of nursing doctoral education with a research focus. This is a significant step forward in enhancing the capability for evaluating doctoral programmes.
本研究旨在评估用于以研究为重点的护理博士项目的护理博士教育质量（QNDE）工具的内容效度、结构效度和信度。
横断面调查研究。
研究团队使用Qualtrics调查向潜在参与者发送电子邮件，提供研究链接和QNDE工具。
共有234名教员和博士生参与：第一阶段有来自14个国家的17名教员；第二阶段有来自20个国家的111名教员和106名博士生。
分两个阶段检验QNDE四个领域（项目、教员、资源和评估）的内容效度、内部一致性信度和结构效度。在2018年6月至2019年3月期间从教员和学生的目的样本中收集数据。在MPlus 8中使用稳健加权最小二乘均值和方差（WLSMV）调整估计量对有序量表进行验证性因子分析。
当项目显示出内容效度（I-CVI>0.78）时，四个领域中项目的内容效度被接受。使用Cronbach's alpha计算四个领域的内部一致性信度，α = 0.88至0.97。基于模型拟合统计量通过验证性因子分析确定QNDE的结构效度。每个领域中所有项目的因子载荷系数具有统计学意义（>0.5；p <.001）。
来自四大洲20个国家的234名教员和博士生的参与证实了QNDE工具的内容效度、内部一致性信度和结构效度。这些发现支持了这种修订后的QNDE工具在评估以研究为重点的护理博士教育质量方面的可信度。这是在提高博士项目评估能力方面向前迈出的重要一步。
