Introduction: General versus specific measures and the special case of core self‐evaluations
介绍《组织行为学杂志》上关于人格测量中一般性与特定性测量水平的辩论，聚焦核心自我评价构念的合理性，为研究者选择测量层次提供参考。
Summary This paper introduces a Journal of Organizational Behavior point/counterpoint exchange (this issue) that focuses on the appropriate level of aggregation primarily in the assessment of personality in general and core self‐evaluations (CSE) in particular. Gilad Chen reviews arguments for and against the higher‐order construct of CSE, offering a number of recommendations for strengthening it. Timothy Judge and John Kammeyer‐Mueller offer a defense of CSE, and then extend the discussion to the measurement of other constructs beyond the personality domain. Together these two papers provide important insights about the appropriate level of aggregation of individual measures, and situations in which higher‐order versus lower‐order measures might be preferred.
