Nurses are continually faced with multiple demands to make decisions in their clinical practice. The Nursing Decision-Making Instrument (NDMI) assesses nurses' decision-making styles during the several stages of this process.
To adapt the NDMI into European Portuguese and evaluate the psychometric properties of the Portuguese version in a population of Portuguese nurses.
Descriptive study design was used to examine psychometric properties of NDMI. Nonprobability convenience sample of 339 Portuguese direct-care nurses. Data were collected using a questionnaire comprising sociodemographic and professional data and the NDMI-Portuguese version (NDMI-PT). An exploratory factor analysis (EFA; = 125) and a confirmatory factor analysis (CFA; = 214) were carried out using IBM SPSS (v. 24) and AMOS (v. 22).
The EFA revealed a structure of four latent factors, which represent the reorganized stages of the decision-making process. The CFA found a good overall fit of the model (χ/df = 2.13; comparative fit index [CFI] = 0.91; goodness of fit index [GFI] = 0.82; Tucker-Lewis Index [TLI] = 0.90; root mean square error of approximation [RMSEA] = 0.07; maximum-likelihood expected cross-validation index [MECVI] = 3.13). The psychometric analysis of the theoretical structure revealed that the four factors reflect the decision-making stages and have a better overall fit than the empirical structure (χ/df = 1.82; CFI = 0.94; GFI = 0.86; TLI = 0.93; RMSEA = 0.06; MECVI = 2.55). The analysis of the construct reliability of the NDMI-PT revealed that the overall internal consistency was excellent (=0.96).
This study revealed that the empirical and theoretical structures were appropriate and valid for the sample under analysis. The NDMI-PT is a reliable and valid tool for assessing nurses' decision-making styles. Studies should be conducted to gain further insight into the robustness of this validated tool.
护士在临床实践中不断面临着做出决策的多重要求。护理决策工具（NDMI）评估护士在这一过程的几个阶段中的决策风格。
将NDMI改编为欧洲葡萄牙语版本，并评估葡萄牙语版本在葡萄牙护士群体中的心理测量特性。
采用描述性研究设计来检验NDMI的心理测量特性。对339名葡萄牙直接护理护士进行非概率便利抽样。使用一份包含社会人口学和专业数据以及NDMI葡萄牙语版本（NDMI-PT）的问卷收集数据。使用IBM SPSS（v. 24）和AMOS（v. 22）进行探索性因素分析（EFA；n = 125）和验证性因素分析（CFA；n = 214）。
探索性因素分析揭示了四个潜在因素的结构，这四个潜在因素代表了决策过程的重新组织阶段。验证性因素分析发现模型整体拟合良好（χ/df = 2.13；比较拟合指数[CFI] = 0.91；拟合优度指数[GFI] = 0.82；塔克-刘易斯指数[TLI] = 0.90；近似误差均方根[RMSEA] = 0.07；最大似然期望交叉验证指数[MECVI] = 3.13）。对理论结构的心理测量分析表明，这四个因素反映了决策阶段，并且比实证结构具有更好的整体拟合度（χ/df = 1.82；CFI = 0.94；GFI = 0.86；TLI = 0.93；RMSEA = 0.06；MECVI = 2.55）。对NDMI-PT的结构可靠性分析表明，总体内部一致性极佳（α = 0.96）。
本研究表明，实证结构和理论结构对于所分析的样本是合适且有效的。NDMI-PT是评估护士决策风格的可靠且有效的工具。应开展研究以进一步深入了解这一经过验证工具的稳健性。
