摘要

This study was designed to evaluate the Judgment of Line Orientation (JOLO) test, a measure of spatial-perceptual skills, as an embedded performance validity test (PVT) in a sample of personal injury litigants with limited English proficiency (LEP). Archival data were collected from a consecutive case sequence of 38 patients (MAge = 47.3; MEducation = 13.3) with LEP and mostly (94.7%) mild TBI in a medicolegal setting. The classification accuracy of the JOLO was evaluated against psychometrically defined invalid performance. A JOLO score of ≤ 19 emerged as the optimal cutoff (.74–.83 sensitivity at .93–1.00 specificity) that correctly classified 82–89% of the sample. The JOLO was a non-significant predictor of a validity composite based on embedded PVTs with high verbal mediation. The inferior classification accuracy against language-based criterion PVTs provides evidence for the domain specificity effect. The JOLO as an embedded PVT outperformed expectations based on previous studies, suggesting that it is a useful measure of performance validity in examinees with LEP that is independent of English proficiency. Further research is needed on diagnostically and geographically heterogeneous samples to consolidate its evidence base in examinees with LEP.
