The Memory Complaints Inventory (MCI) is a stand-alone memory-based symptom validity test. The measure is promising and has been used with relative frequency but requires additional research (Armistead-Jehle & Shura, 2021). The current study sought to expand the empirical base of the MCI by comparing it to the Cognitive Bias Scale, a new symptom validity measure assessing cognitive over-reporting on the Personality Assessment Inventory (PAI). Military service members seen for neuropsychological evaluation (n=273) were administered the PAI and MCI. AUC values for the MCI overall mean score and MCI implausible scales for a PAI CBS cut score of >14 were large in effect (.77 and .78, respectively). The effect size between those that passed and failed the CBS on the mean of MCI scales was also large (d =1.13). Classification statistics indicated that a cut score of 52% on the Mean MCI scales and 29% on the mean MCI implausible subscales indicated specificities of .94 and .93 and sensitivities of .30 and .29, respectively. These data support the MCI as a cognitive SVT relative to the PAI CBS.
