The criterion validity of broad factor scales versus specific facet scales

We compared the validities of two Big Five personality factor scales with these of two lower-level facet scales that constituted each factor scale, with respect to self-report behavior criteria. Results demonstrated that the factor scales yielded significantly and substantially lower validities than did their constituent facet scales. These findings support our claim that separate scale scores should be reported routinely for the individual personality facets that define a broad factor, particularly when those facets do not correlate highly and when criteria of interest relate substantively to certain facets within the factor scale but not to others.
