The classification accuracy of the recognition memory test-words as a performance validity test is affected by gender...

Previous research suggested that Recognition Memory Test-Words (RMT-W) scores may be confounded by gender and handedness. This study was designed to examine its classification accuracy as a performance validity test (PVT) and susceptibility to demographic characteristics.

Archival data were collected from a consecutive sequence of 310 diagnostically heterogeneous examinees (181 men; M_Age = 41.4; M_Education = 12.9). The RMT-W's classification accuracy was computed against psychometrically operationalized criterion groups.

Optimal RMT-W cutoffs (≤ 42 to ≤ 40) produced a good combination of sensitivity (.62-.70) and specificity (.90-.96), correctly classifying 85.6%-87.7% of the sample. Women scored 1.5 points higher. RMT-W scores were unrelated to handedness but were correlated with education. A linear relationship emerged between level of education and the cutoff needed to achieve ≥ .90 specificity: ≤ 43 for ≥ 13 years of education, ≤ 41 for 12 years of education, and ≤ 39 for ≤ 11 years of education. RMT-W ≤ 45 had .91 specificity in women with postsecondary education.

Results suggest that overall, the RMT-W remains an effective free-standing PVT. Gender, age, and handedness in isolation had minimal impact on RMT-W scores. However, education had a clinically significant effect. The combined effect of gender and education produced a marked shift in classification accuracy. Systematic research is needed on the relationship between demographics and PVT outcomes to ensure that cutoffs have the same clinical interpretation regardless of patient variables.
