“…It ranges from 0 (passing the most liberal cutoff on all five PVTs) to 15 (failing the most conservative cutoff on all five PVTs). As such, the specialty EI-5 capture both the number and extent of PVT failures, providing a more nuanced assessment of performance validity that recognizes the underlying continuity in the target construct (Lippa, Agbayani, Hawes, Jokic, & Caroselli, 2014). Each unit increase on the EI-5 is associated with an increase in the confidence that the response set has been correctly classified as invalid .…”

A link between noncredible responding and low scores on the Grooved Pegboard Test (GPB) is well documented in the clinical literature. However, no specific validity cutoffs have emerged in previous research. This study was designed to examine the classification accuracy of various demographically adjusted cutoffs on the GPB against established measures of performance validity. Analyses were based on a mixed clinical sample of 190 patients (52.1% female) medically referred for neuropsychological assessment. Mean age of participants was 44.1 years, with a mean education of 13.9 years. Criterion measures were the Recognition Memory Test and 3 composites based on several embedded validity indicators. A T score Յ29 for either hand or Յ31 on both hands were reliable markers of invalid performance (sensitivity ϭ .29 -.63; specificity ϭ .85-.91). Ipsative analyses revealed that these T score-based cutoffs have zero false positive rates. Failing these cutoffs had no consistent relationship with overall cognitive functioning. A moderate relationship between GPB failure and self-reported anxiety and depression emerged on face-valid screening measures. There was also a moderate relationship between GPB failure and Personality Assessment Inventory scales measuring somatic complaints, borderline traits, antisocial features, and substance use. The newly introduced GPB validity cutoffs were effective at separating credible and noncredible performance on neuropsychological testing. The complex relationship between failing the GPB and emotional problems is consistent with the psychogenic interference hypothesis. It may provide insight into the mechanism behind invalid responding and thus warrants further investigation.

“…73,74 Additionally, the practice of dichotomizing PVT performance may be limiting, as useful information may be gleaned from the evaluation of PVT performance on a continuum. 26,27,98 Clearly, additional research examining these proposed hypotheses—especially in the context of neuroimaging findings—is needed.…”

Objective Failure on performance validity tests (PVTs) is common in Veterans with histories of mild traumatic brain injury (mTBI), leading to questionable validity of clinical presentations. Participants Using diffusion tensor imaging (DTI), we investigated white matter (WM) integrity and cognition in 79 Veterans with history of mTBI who passed PVTs (n = 43; TBI-Passed), history of mTBI who failed at least one PVT (n = 13; TBI-Failed), and military controls (n = 23; MCs) with no history of TBI. Results The TBI-Failed group demonstrated significantly lower cognitive scores relative to MCs and the TBI-Passed group; however, no such differences were observed between MCs and the TBI-Passed group. On a global measure of WM integrity (i.e., white matter burden), the TBI-Failed group showed more overall WM abnormalities than the other groups. However, no differences were observed between the MCs and TBI-Passed group on white matter burden. Interestingly, regional WM analyses revealed abnormalities in the anterior internal capsule and cingulum of both TBI subgroups relative to MCs. Moreover, compared to the TBI-Passed group, the TBI-Failed group demonstrated significantly decreased WM integrity in the corpus callosum. Conclusions Findings revealed that, within our sample, WM abnormalities are evident in those who fail PVTs. This study adds to the burgeoning PVT literature by suggesting that poor PVT performance does not negate the possibility of underlying WM abnormalities in military personnel with history of mTBI.

“…Évidemment, un score à un TVP se situant tout juste en deçà d'un score seuil n'a pas la même valeur interprétative qu'un score si faible qu'il s'approche du niveau du hasard. De plus en plus d'études nous permettent d'ajuster les cotes de sensibilité/spécificité en fonction du score obtenu, pas seulement en fonction d'un score seuil (Lippa, Agbayani, Hawes, Jokic et Caroselli, 2014;Lippa et al, 2017;Walters, Berry, Rogers, Payne et Granacher, 2009). Il y aura toujours des cas limites.…”

Validité Et Crédibilité Dans Le Contexte De L’expertise en Neuropsychologie Clinique

Au cours des dernières décennies, une multitude de tests et d’indices ont été développés pour tenter de détecter la non-validité des résultats neuropsychologiques. Cependant, la prolifération et la popularité de ces mesures ont contribué à la perception qu’il est dorénavant possible de les utiliser pour identifier la simulation des troubles cognitifs (malingering). Dans cet article, un cadre conceptuel est présenté pour tenter de favoriser une meilleure compréhension des notions sous-jacentes et permettre une meilleure interprétation de la non-validité en expertise. Selon la présente conceptualisation, il existe deux étapes distinctes : la première consiste à discerner la non-validité des données à l’aide de méthodes psychométriques, notamment les tests de validité de performance (TVP). La deuxième requiert une décision quant à la crédibilité du tableau clinique, incluant un jugement quant à la cohérence de l’ensemble des informations cliniques. C’est seulement dans le contexte de certaines incohérences indéniables qu’il serait possible d’avancer une opinion évoquant l’amplification des problèmes cognitifs.
