Rey 15-item memorization and Dot counting scores in a "stress" claim worker's compensation population: relationship to personality (MCMI) scores.

The relationship between apparent faking of cognitive impairment (as detected by such "malingering" tests as 15-item Memorization and Dot Counting) and faking of psychiatric symptoms has not been investigated formally. In addition, no empirical literature is available on the relationship between personality traits and faking of cognitive symptoms. Of 154 subjects who claimed "stress" psychiatric injury, 12% appeared to be faking cognitive impairment; 4.5% failed the 15-item Memorization Test, and 10% failed the Dot Counting task. Faking of cognitive symptoms occurred in only 23% of subjects who were faking/exaggerating psychological symptoms on the MCMI. Malingering test failure was associated with significant elevations on MCMI personality scales, although this appeared to be an artifact of attempts to fake/exaggerate on the MCMI, rather than a reflection of "true" personality traits.
