Effects of Item Context Specificity on the Measurement Equivalence of a Personality Inventory
研究在大型实地样本中检验了情境化(工作情境)与非情境化(一般情境)人格量表在尽责性维度上的心理测量特性差异,发现工作情境量表误差方差略低,对人格量表开发与使用有参考价值。
Personality measures with items that ask respondents to characterize themselves across a range of situations are increasingly used for personnel selection purposes. Research conducted in a laboratory setting has found that personality items may have different psychometric characteristics depending on the degree to which that range is widened or narrowed (i.e., degree of contextualization). This study is an attempt to study the psychometric impact of contextualization in a large field sample (N = 1,078). Respondents were given either a contextualized (at work) or noncontextualized (in general) version of the six facets of the conscientiousness factor of the NEO PI-R. Analyses were conducted at the facet and item levels. Results were mixed but indicated that error variances tended to be slightly lower for the work-specific instrument in comparison to the noncontextualized instrument. Implications for personality inventory development, validation, and use are discussed.
