The Test Validation Summary applies mixed-groups validation to investigate the meaning of test constructs and to estimate test classification characteristics when test validation groups are not "pure" criterion groups (ie, "compliant" vs "malingering"), but members have variable probability of malingering. The method permits the use of tests with relatively low validity to validate tests of greater validity. In our initial analysis, we argue that the Rey 15-Item Memory Test is best construed as an "intention test" (capturing the intention of testtakers when..
