This study examined the extent to which demographic variables (i.e., age, education, premorbid IQ, sex, ethnoracial identity, and presence/absence of external incentive) affect performance validity test (PVT) performance.This cross-sectional two distinct, diverse outpatient clinical samples at an academic medical center (AMC, N = 268) a Veterans Affairs (VA) (N 111). All patients completed battery including five PVTs. Premorbid IQ was assessed using Test Functioning (TOPF) in AMC sample.Multiple correlations between individual PVT were statistically significant, but accompanying effect sizes small, except for relationship reliable digit span (RDS). Regressions showed accounted 7%-11% variance scores sample, 6%-26% VA driving results sample compensation-seeking status sample. Other did not correlate with status. Additionally, found be significantly higher validly performing individuals compared those invalidly sample.Most factors evaluated relatively little predict overall categorization. Compensation-seeking correlated classification across both groups, offers limited diagnostic utility itself objective scores. within group demonstrated influence on particular PVTs RDS) reflecting difficulty assessing low populations, particularly more strongly IQ.
