 ity test reflects suspicion and imagination - Dr. David Stillwell\, Depart

DESCRIPTION:Person-fit statistics measure the likelihood of a candidate’
 s questionnaire responses\, given the model used to calculate their scores
 . An unlikely set of responses would be to get all the difficult questions
  right and the easy questions wrong. Low person-fit on a personality quest
 ionnaire might be due to inattention when answering\, an attempt to manipu
 late the results\, psychological traits of the candidate\, or an untraited
  individual. We tested these hypotheses using 100-item Big Five test resul
 ts from 150\,000 participants and 6 different subsamples\, including self-
 monitoring scores\, NEO facet scores\, impression management and fair-mind
 edness scores\, time taken to complete a questionnaire\, test-retest corre
 lations\, and self-other correlations. We found that person-fit is stable 
 over 275 days (mean r = .46)\, and that suspicious individuals\, and intel
 lectual and imaginative individuals have a low person-fit. We find scant e
 vidence that low person-fit can improve the validity of a personality ques
 tionnaire by removing inattentive respondents.
