Abstract
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.
