Unmotivated or suspicious test takers in concurrent
validation studies can cause numerous
problems for test users. 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,
