Beschreibung:
<jats:p> Unmotivated or suspicious test takers in con current 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 appro priateness fit indexes to identify and remove from a validation sample those examinees whose response patterns did not match their trait levels (e.g., examin ees with low trait levels who answered difficult items correctly). The person-fit index l<jats:sub>z</jats:sub> described in Drasgow, Levine, & Williams (1985) had little effect on validities. The multitest index l<jats:sub>zm</jats:sub> described by Drasgow & Hulin (1990) was more promising. Implications for selection research and practice are discussed. </jats:p>
