Researchers have used the Practice Environment Scale of the Nursing Work Index (PES-NWI) to examine the perception of practice environment among U.S. nurses in general; however, the scale has not been used to measure perceptions specifically among Asian nurses working in the United States, the largest group of international nurses in the nation.
The purpose of this study was to test the reliability and the validity of the PES-NWI scale when applied to Asian nurses working in the United States.
The study used a cross-sectional design with snowball sampling. Data from 230 Asian nurses who were born in Far Eastern countries and had worked at least 6 months in their current job at a U.S. hospital were analyzed, using Cronbach's alpha, item-total and interitem correlation, and factor analysis.
The Cronbach's alpha for the PES-NWI was.96, and the item-total correlation coefficients ranged from.49 to.79. Five factors, which explained 59.12% of variance in the perception of practice environment, emerged: Nurse Participation and Development; Nurse Manager Ability, Leadership, and Support of Nurses; Nursing Foundations for Quality of Care; Staffing and Resource Adequacy; and Collegial Nurse-Physician Relations. Four derived factors were reconstructed, and one factor was renamed based on the meanings of scale items that were included in the factor.
Study findings demonstrate that the PES-NWI is a reliable and a valid scale when applied to Asian nurses working in the United States. Findings also indicate that Asian nurses perceive practice environments differently than do American nurses, most likely due to dissimilar cultural beliefs. A better understanding of these differences may help develop more individualized support for Asian nurses as they adapt to working in the United States.
研究人员已使用护理工作指数实践环境量表(PES-NWI)来考察美国护士对实践环境的总体认知;然而,该量表尚未用于专门测量在美国工作的亚洲护士(该国最大的国际护士群体)的认知情况。
本研究的目的是检验PES-NWI量表应用于在美国工作的亚洲护士时的信度和效度。
本研究采用横断面设计和滚雪球抽样法。分析了230名出生于远东国家、在美国医院当前岗位工作至少6个月的亚洲护士的数据,使用了克朗巴哈系数、项目-总分相关和项目间相关以及因子分析。
PES-NWI的克朗巴哈系数为0.96,项目-总分相关系数范围为0.49至0.79。出现了五个因素,解释了实践环境认知中59.12%的方差:护士参与和发展;护士长能力、领导力及对护士的支持;护理质量基础;人员配备和资源充足性;以及护士与医生的合作关系。根据包含在因子中的量表项目含义,对四个衍生因子进行了重构,对一个因子进行了重新命名。
研究结果表明,PES-NWI量表应用于在美国工作的亚洲护士时是可靠且有效的。研究结果还表明,亚洲护士对实践环境的认知与美国护士不同,很可能是由于文化信仰不同。更好地理解这些差异可能有助于在亚洲护士适应在美国工作时为其提供更具个性化的支持。
