目的/目标：为了检验护理工作指数（PES-NWI）的实践环境量表的修改项目在未充分研究的门诊肿瘤学环境中使用的可靠性和有效性。设计：采用修改的Dillman方法进行横断面邮寄调查。设置：美国东南部。样本：以人口为基础的全州样本，1,339名肿瘤科护士报告在医院住院部以外就业。方法：在检验了无回答偏差后，采用结构方程模型和Cronbach系数α的验证性因素分析分别检验了结构效度和内部一致性。在计算每个护士的修订后的子量表平均值后，研究人员使用t检验来比较报告其实践环境为有利的护士与报告其实践环境为混合或不利的护士之间的子量表平均值。主要研究变量：PES-NWI改编版项目的可靠性和有效性。尽管应答率为31%，但在分析样本和无应答者之间没有观察到人口统计学特征的差异。在将项目数量减少到23个后，实现了可接受的模型拟合，比较拟合指数为0.95，近似均方根误差为0.057。所有五个现有的PES-NWI分量表，加上新的医疗助理支持分量表，护士谁报告有利的实践环境与那些谁报告混合或不利environment.Conclusions：修订后的一组项目来自PES-NWI具有可接受的可靠性和有效性，以衡量门诊肿瘤设置的护理实践环境的质量。医疗助理的支持是一个新的贡献项目pool.Implications护理：在不同样本的护士，包括研究，与病人的结果，这一修订措施的额外测试，是必要的下一步。
Purpose/Objectives: To examine the reliability and validity of modified items from the Practice Environment Scale of the Nursing Work Index (PES-NWI) for use in the understudied ambulatory oncology setting.Design: Cross-sectional mailed survey using a modified Dillman method.Setting: Southeastern United States.Sample: Population-based statewide sample of 1,339 oncology nurses who reported employment outside of hospital inpatient units.Methods: After examining for nonresponse bias, confirmatory factor analysis using structural equation modeling and Cronbach coefficient alphas were employed to examine construct validity and internal consistency, respectively. After calculating revised subscale means for each nurse, the researchers used t tests to compare subscale means between nurses who reported their practice environment as favorable versus those who reported it as mixed or unfavorable.Main Research Variables: Reliability and validity of items on the adapted version of the PES-NWI.Findings: Despite a response rate of 31%, no differences in demographic characteristics were observed between the analytic sample and nonresponders. After reducing the number of items to 23, acceptable model fit was achieved with a comparative fit index of 0.95 and a root mean square error of approximation of 0.057. All five existing PES-NWI subscales, plus the new medical assistant support subscale, were significantly higher for nurses who reported favorable practice environments versus those who reported mixed or unfavorable environments.Conclusions: A revised set of items derived from the PES-NWI has acceptable reliability and validity to measure the quality of nursing practice environments in ambulatory oncology settings. Medical assistant support is a new contribution to the item pool.Implications for Nursing: Additional testing of this revised measure in diverse samples of nurses, including studies that correlate with patient outcomes, is a necessary next step.
