Perceived environmental uncertainty is an individual response to stimuli in the internal and/or external environment. The measurement of uncertainty in the health care environment is important in order to characterize the impact of this phenomenon on nursing practice. This study describes the development, pilot testing, and initial psychometric evaluation of the Perceived Environmental. Uncertainty in Hospitals Scale (PEU-H) in a sample of 95 hospital staff registered nurses. Principal components analysis of the PEU-H was conducted and indicated that the factor structure represented one factor that explained 37.3% of the variance. Internal consistency reliability using Cronbach's alpha was .83, which is acceptable for a scale in the early stages of development.
感知到的环境不确定性是个体对内部和/或外部环境中刺激的反应。为了描述这种现象对护理实践的影响，衡量医疗保健环境中的不确定性很重要。本研究描述了在95名医院注册护士样本中进行的“医院环境感知不确定性量表（PEU-H）”的编制、预测试和初步心理测量学评估。对PEU-H进行了主成分分析，结果表明该因子结构代表一个解释了37.3%方差的因子。使用克朗巴哈系数的内部一致性信度为0.83，对于处于开发早期阶段的量表来说是可以接受的。
