To evaluate the relationships among performance validity, symptom self-report, and objective cognitive testing.Combat Veterans (N = 338) completed a neurocognitive assessment battery several self-report measures assessing depression, posttraumatic stress disorder (PTSD) symptoms, sleep quality, pain interference, neurobehavioral complaints. All participants also two validity tests (PVTs) one stand-alone test (SVT) along with embedded SVTs.Results of an exploratory factor analysis revealed three-factor solution: performance, report (SVTs loaded on third factor). Results t demonstrated that who failed PVTs displayed significantly more severe symptoms worse most functioning compared to those passed. Participants SVT reported symptomatology all measures, but pattern differed based selected cutoff. Multiple linear regressions both PVT failure explained unique variance in report, only predicted performance.Performance measure distinct related constructs. SVTs are report; however, relationship between is strongest. differentially utilized cutoff score. (PsycInfo Database Record (c) 2021 APA, rights reserved).
