The Memory Integrated Language Test: Cross-validation of a web-based performance validity test.

= 52) groups. In the overall sample, the MIL demonstrated outstanding classification accuracy (a significant area under the curve = .96), with a cutoff score of ≤44 (96% sensitivity/91% specificity). Across diagnostic groups, the MIL maintained outstanding classification accuracy (area under the curve = .90-.97) with strong sensitivity and specificity. Convergent validity analyses indicated expected associations with other memory-based PVTs, while discriminant validity analyses yielded weak associations with executive function and memory domains. Supplemental analysis using a ≥1 PVT failure threshold yielded acceptable classification accuracy (area under the curve = .78), with a cutoff score of ≤44 (53% sensitivity/96% specificity). Findings indicate that the MIL is a psychometrically robust freestanding PVT. (PsycInfo Database Record (c) 2026 APA, all rights reserved).
