12/2/2023 0 Comments Moca score interpretation wikiWe hypothesized that indicators of invalid response style (i.e., failure on PVTs and SVTs) would incrementally influence total MoCA scores, in that as the number of such indicators increased, MoCA scores would decrease. This study was designed to evaluate the influence of suboptimal performance validity test (PVT) and symptom validity test (SVT) performances on scores derived from the MoCA. 12 Establishing both validity of cognitive data via tests specifically designed to assess performance validity and validity of symptom self-report via measures designed to assess symptom validity is crucial to drawing conclusions regarding impairment. 8 Given high rates of reporting cognitive symptoms among those with histories of mTBI 9, 10 in the context of evidence that persistent cognitive deficits are unlikely to be directly related to neurologic injury, 11 the importance of assessing validity has been highlighted within this population. 3Ĭonsiderable research in mild traumatic brain injury (mTBI) 7 suggests that cognitive, physical, and emotional symptoms resolve rapidly in most individuals, with full return to baseline within days to weeks. 4, – 6 Nevertheless, evidence suggests that the MoCA should be not be interpreted solely as a measure of cognitive ability, as doing in many instances would lead to excessive false-positive diagnoses because of noncognitive factors. 1 Research has demonstrated utility of the MoCA across many neurologic populations. The MoCA does not comprehensively measure cognition rather, it provides an estimate of global cognition, assisting clinicians when deciding whether to make referrals for neuropsychological evaluation. 1 Several studies have demonstrated its psychometric superiority 2, 3 over other screening instruments. The Montreal Cognitive Assessment (MoCA) is a cognitive instrument developed to screen for mild cognitive impairment and dementia.
