A sample of N = 428 persons completed a personality CAT as part of a career development procedure. To detect inconsistent item score patterns, we used a cumulative sum (CUSUM) procedure. Combined information from the CUSUM, other personality measures, and interviews showed that similar estimated trait values may have a different interpretation.Implications for computer-based assessment are discussed. %B Personality and Individual Differences %V 48 %P 921-925 %@ 01918869 %G eng %0 Book Section %D 2007 %T The development of a computerized adaptive test for integrity %A Egberink, I.
