Abstract
< .001) on TOMM T1 and TOMMe10, with lower TOMM T1 and higher TOMMe10 scores for participants with invalid performance. Using established cut-scores, sensitivities/specificities were: TOMMe10 ≥1 error: .84/.66; ≥2 errors: .74/.93; TOMM T1 ≤40: .82/.93. ROC curve analysis yielded significant areas under the curve for both TOMMe10 and T1 with respective optimal cut-scores of ≥2 errors (.74 sensitivity/.93 specificity) and ≤41 (.84 sensitivity/.91 specificity). TOMMe10 and T1 performances are minimally impacted by cognitive impairment. Although both evidenced robust psychometric properties, TOMM T1 continued to show greater accuracy than TOMMe10.
