OBJECTIVE
The purpose of this study is to examine the psychometric properties of the Patient Care Associates' Work Environment Scale (PCA-WES).
BACKGROUND
Few studies exist examining patient care associates (PCAs) working in acute care settings, and no instruments are available to examine the impact of the work environment on their practice.
METHODS
A psychometric evaluation using a nonprobability purposive sample of 390 PCAs was undertaken.
RESULTS
Cronbach's α internal consistency reliability of the total score was .95. Principal components analysis with varimax rotation and Kaiser normalization identified 5 components that accounted for 57.2% of variance and confirmed the original theoretical structure. The resulting 35-item scale had subscale Cronbach's α reliability estimates that ranged from .84 to .93.
CONCLUSIONS
The multidimensional PCA-WES is a psychometrically sound measure of 5 components of the PCA practice environment in the acute care setting and is sufficiently reliable and valid for use as independent subscales in healthcare research.
目的
本研究旨在检验患者护理助理工作环境量表（PCA-WES）的心理测量特性。
背景
很少有研究关注在急症护理环境中工作的患者护理助理（PCA），并且没有可用的工具来检验工作环境对其工作的影响。
方法
采用非概率立意抽样法对390名PCA进行心理测量评估。
结果
总分的克朗巴哈α内部一致性信度为0.95。采用方差最大化旋转和凯泽标准化的主成分分析确定了5个成分，这些成分占方差的57.2%，并证实了原始的理论结构。由此产生的35个条目的量表的分量表克朗巴哈α信度估计值在0.84至0.93之间。
结论
多维PCA-WES是对急症护理环境中PCA实践环境的5个成分进行心理测量的有效工具，作为独立的分量表在医疗保健研究中使用具有足够的可靠性和有效性。
