A-178 Might Tip-of-the-Tongue Responses on the Auditory and Visual Naming Test be a Useful Embedded Performance Validity Measure in the Language Domain?

Abstract

\n \n \n This study examined whether responses on the Auditory and Visual Naming Test (ANT/VNT) would discriminate between veterans with invalid and valid test performance, thus suggesting a novel embedded performance validity test (PVT) for a language task.\n \n \n \n Veterans who completed the ANT/VNT and failed two or more PVTs were selected for inclusion, resulting in a sample of 9 veterans (8 males; Mage\u2009=\u200955.8, SD\u2009=\u200911.5; Medu\u2009=\u200912.7, SD\u2009=\u20092.1). An age-and education-matched group of 9 cognitively unimpaired veterans who passed PVTs (7 males; Mage\u2009=\u200956.1, SD\u2009=\u200911.5; Medu\u2009=\u200914.0, SD\u2009=\u20092.4) were selected from a database of patients from the same clinical setting. Variables of interest included tip-of-the-tongue (TOT) responses (responses with a latency between 2 and 20\xa0seconds) and Total Correct responses for the ANT/VNT.\n \n \n \n Groups were comparable on demographic characteristics and there were no statistical differences in Total Correct responses on ANT/VNT. The invalid group had more TOT on both the visual (M\u2009=\u20094.2, SD\u2009=\u20093.8) and auditory (M\u2009=\u200914.4,SD\u2009=\u20099.7) tasks, as compared to the valid group (Mvisual\u2009=\u20090.7, SD\u2009=\u20090.7; Mauditory\u2009=\u20094.9,SD\u2009=\u20092.7). ROC curve analysis for detecting invalid performance was significant for both VNT-TOT (AUC\u2009=\u20090.79, p\u2009=\u20090.038) and ANT-TOT (AUC\u2009=\u20090.88, p\u2009=\u20090.006). A cutoff of 1 was optimal for VNT-TOT (sensitivity\u2009=\u20090.67, specificity\u2009=\u20090.89), while 6 was optimal for ANT-TOT (sensitivity\u2009=\u20090.89, specificity\u2009=\u20090.89).\n \n \n \n Despite the small sample size, findings are promising regarding the utility of ANT/VNT TOT responses as embedded PVTs. These should be further explored since the field is in need of validity measures embedded within language/naming tasks. Visual Naming Test may be particularly useful given that it can take less than 5\xa0minutes to administer.\n
