The predictive power of people’s intraindividual variability across situations: Implementing whole trait theory in assessment.
研究通过情境判断测验测量人们在多个工作情境中的特质得分及其变异性，发现个体内变异性可预测功能灵活性和实际人格状态变化，为评估实践提供动态指标。
In the last decade, there has been increased recognition that traits refer not only to between-person differences but also to meaningful within-person variability across situations (i.e., whole trait theory). So far, this broader more contemporary trait conceptualization has made few inroads into assessment practices. Therefore, this study focuses on the assessment and predictive power of people's intraindividual variability across situations. In three studies (either in student or employee samples), both test-takers' mean trait scores and the variability of their responses across multiple written job-related situations of a situational judgment test (SJT) were assessed. Results revealed that people's intraindividual variability (a) was related to their self-rated functional flexibility, (b) predicted performance above their mean scores, and (c) predicted their actual personality state variability over 10 days. These results open opportunities for complementing traditional selection procedures with more dynamic indices in assessment. (PsycINFO Database Record
