Clinical Decision-Making in Nursing Scale (CDMNS-PT©) in nursing students: translation and validation

ABSTRACT Objectives: to validate, for the Portuguese population, the Clinical Decision-Making Nursing Scale© (CDMNS©). Methods: this methodological study involved 496 nursing students who filled in a questionnaire created using sociodemographic and academic data, and the scale to evaluate the making of decisions in nursing. Results: the confirmatory factorial analysis showed that the adjustment of the factorial structure has good quality, being made up by three factors (X2/gl = 2.056; GFI = 0.927; CFI = 0.917; RMSEA = 0.046; RMR = 0.039; SRMR = 0.050). For the scale to be reliable, it had to include only the reliability of the scale required it to be constituted by 23 items, with correlation values that varied from 0.184 and 0.610, and a global Cronbach's Alpha of 0.851, which showed its good reliability. Conclusions: the CDMNS-PT© is valid and reliable, showing a high potential to be used in clinical practice and investigation.

摘要
研究目的：针对葡萄牙人群验证临床决策护理量表©（Clinical Decision-Making Nursing Scale©，CDMNS©）的效度与适用性。
研究方法：本项方法学研究共纳入496名护理专业学生，受试者填写了基于社会人口学与学术数据编制的调查问卷，以及用于评估护理决策制定的该量表。
研究结果：验证性因子分析结果显示，该量表的因子结构适配性良好，共包含3个因子（X²/gl=2.056；拟合优度指数GFI=0.927；比较拟合指数CFI=0.917；近似误差均方根RMSEA=0.046；残差均方RMR=0.039；标准化残差均方根SRMR=0.050）。为确保该量表具备可靠信度，需保留23个条目，各条目间相关系数介于0.184至0.610之间，整体克朗巴哈α系数为0.851，表明该量表具有良好的信度。
研究结论：临床决策护理量表葡萄牙语版©（CDMNS-PT©）具有良好的效度与信度，在临床实践与相关研究中具备较高的应用潜力。
