Use of the WAIS-III picture completion subtest as an embedded measure of response bias.

Clinical Neuropsychologist 24(7):1243 (2010) PMID 20924983

In the present study a large sample of credible patients (n = 172) scored significantly higher than a large sample of noncredible participants (n = 195) on several WAIS-III Picture Completion variables: Age Adjusted Scaled Score, raw score, a "Rarely Missed" index (the nine items least often missed by credible participants), a "Rarely Correct" index (nine items correct index, 76.7% of less-educated noncredible participants were detected as compared to 58.3% of better-educated noncredible participants. Results of the current study suggest that the Picture Completion subtest of the WAIS-III is an effective measure of response bias, and that it may have a unique role in identifying suboptimal effort in less-educated test takers.
