Several studies have examined the relationship between performance and symptom validity via structural equation modeling for the MMPI-2 & MMPI-2-RF, where a weak to moderate relationship between performance and symptom validity has been observed. The present study extends this previous research by examining the relationship between the Test of Memory Malingering (TOMM) and the Personality Assessment Inventory (PAI) symptom validity tests. Participants included 638 consecutive clinical referrals for neuropsychological evaluation who completed the both the TOMM and the PAI (mean Age = 41.8, SD = 15.7; mean Education = 13.7, SD = 2.7; 53% female; 89% Caucasian). A latent variable model was fit following exploratory factor modeling that suggested a three-factor solution comprising cognitive performance validity, symptom overreporting, and symptom underreporting. The overall model demonstrated good fit with commonly used fit indices (e.g., Comparative Fit Index = 0.97), with a modest relationship between performance validity and symptom overreporting (r = -0.31, p<0.001), a stronger relationship between symptom overreporting and symptom underreporting (r = -0.56, p<0.001), with no significant relationship between symptom underreporting and performance validity (r = 0.07, p = 0.11). Overall, these findings are consistent with those found utilizing the MMPI-2 & MMPI-2-RF.
