Measuring facets of job ambiguity: Construct validity evidence.
开发了一个能测量工作方法、时间安排和绩效标准三个不同方面模糊性的工具，并通过四项研究验证了其信度和效度，对组织行为研究者和实践者有用。
In the past 2 decades, the importance of role ambiguity as an organizational variable has been well established. Recently, researchers have suggested that the lack of an instrument capable of measuring different facets of ambiguity may have impeded both theory development and application of research results. This article presents the development of an instrument capable of tapping 3 distinct aspects of job ambiguity (work method, scheduling, and performance criteria). Data relevant to the reliability, validity, and importance of the job ambiguity measures were gathered in a series of 4 studies. The results of several statistical analyses suggest that the 3 job ambiguity scales are reliable, valid, and meaningful
