The use of instruments designed to assess the nursing practice environment is crucial to improve the quality of nursing care, to anticipate problems and difficulties that may arise in organizations, and allow nurse managers to implement changes and improvements in key areas. In this study, we aimed to evaluate the psychometric properties of the Nursing Work Index-Revised Portuguese version (NWI-R-PT) scale. A quantitative, observational, descriptive, and cross-sectional study was conducted.
The sample consisted of 767 nurses from 4 public Portuguese hospitals. Exploratory and confirmatory factor analysis techniques were used to test the distinct structural models. The scale's accuracy was evaluated through internal consistency, using Cronbach's alpha.
NWI-R-PT internal consistency was 0.91. The NWI-R-PT model with six factors, namely "Management Support," "Professional Development," "Fundamentals of Nursing," "Nurse-Physician Relationship," "Endowments," and "Organization of Nursing Care," was supported by exploratory and confirmatory factor analysis. The NWI-R-PT scale presents adequate goodness-of-fit indices concerning the final factorial model and the convergent validity.
The NWI-R-PT scale has a competent and reliable structure. The scale's validity is confirmed; therefore, it may be employed in all contexts in clinical practice, research, and nursing management. The NWI-R-PT is a useful and valid instrument to assess the nursing environment in hospitals, primary care, long-term care, and nursing homes. The scale has significance in improving the quality of nursing care and patient safety, the professional development of nurses, and organizational results.
使用旨在评估护理实践环境的工具对于提高护理质量至关重要，可预测组织中可能出现的问题和困难，并使护士管理人员能够在关键领域实施变革和改进。在这项研究中，我们旨在评估修订版葡萄牙语护理工作指数（NWI-R-PT）量表的心理测量特性。这是一项定量、观察、描述性和横断面研究。
样本由来自葡萄牙 4 家公立医院的 767 名护士组成。使用探索性和验证性因子分析技术测试了不同的结构模型。通过 Cronbach's alpha 评估了内部一致性，从而评估了量表的准确性。
NWI-R-PT 的内部一致性为 0.91。NWI-R-PT 模型具有六个因素，分别为“管理支持”、“专业发展”、“护理基础”、“护士与医生关系”、“津贴”和“护理组织”，得到了探索性和验证性因子分析的支持。NWI-R-PT 量表在最终因子模型和收敛有效性方面具有适当的拟合度指数。
NWI-R-PT 量表具有较强的结构能力和可靠性。该量表的有效性得到了确认，因此可以在临床实践、研究和护理管理的所有背景下使用。NWI-R-PT 是一种用于评估医院、初级保健、长期护理和养老院护理环境的有用且有效的工具。该量表在提高护理质量和患者安全、护士的专业发展和组织成果方面具有重要意义。
