Do tests of malingering concur? Concordance among malingering measures
Psychology | Social and Behavioral Sciences
Malingering test accuracy is increasingly a major issue in psychology and law. Integrating results across measures might offset limitations of a single test, but the practical benefits of using several tests depend on the extent to which they misclassify the same individuals. Data from 66 evaluatees were used to assess the degree of overlap and consistency of classification among several commonly used malingering instruments. Although correlative data indicated that measures were highly redundant even across symptom domains, classification accuracy analyses revealed that findings based on conjunctions of these scales may not overlap to the degree that the correlations might suggest.
