The effects of these problems, however, have not been carefully examined. This study used item response theory-based appropriateness fit indexes to identify and remove from a validation sample those examinees whose response patterns did not match their trait levels (e.g., examinees with low trait levels who answered difficult items correctly). The person-fit index lzm described in Drasgow, Levine, & Williams (1985) had little effect on validities. The multitest index lzm described by Drasgow & Hulin (1990) was more promising. Implications for selection research and practice are discussed. Index terms: aberrant response patterns, appropriateness fit, concurrent validity, distorted responses, item response theory, person fit.enArticle
