Reliability and validity of the NeuroCognitive Performance Test, a web-based neuropsychological assessment

Abstract

The NeuroCognitive Performance Test (NCPT) is a brief, repeatable, web-based cognitive assessment platform that measures performance across several cognitive domains. The NCPT platform is modular and includes 18 subtests that can be arranged into customized batteries. Here we present normative data from a sample of 130,140 healthy volunteers for an NCPT battery consisting of 8 subtests. Participants took the NCPT remotely and without supervision. Factor structure and effects of age, education, and gender were evaluated with this normative dataset. Test-retest reliability was evaluated in a subset of participants who took the battery again an average of 78.8 days later. The eight NCPT subtests group into 4 putative cognitive domains, have adequate to good test-retest reliability, and are sensitive to expected age- and education-related cognitive effects. Concurrent validity to standard neuropsychological tests was demonstrated in 73 healthy volunteers. In an exploratory analysis the NCPT battery could differentiate those who self-reported Mild Cognitive Impairment or Alzheimer's disease from matched healthy controls. Overall these results demonstrate the reliability and validity of the NCPT battery as a measure of cognitive performance and support the feasibility of web-based, unsupervised testing, with potential utility in clinical and research settings.

A systematic review of reviews of neurocognitive functioning in eating disorders: The state‐of‐the‐literature and future directions

“…Thus, longitudinal research is needed to clarify whether specific neurocognitive deficits reflect endophenotypes that begin prior to the illness and persist after recovery, start with the onset of the illness and improve with symptom reduction, or might be best viewed as scars of the illness that begin with the onset of the illness, but persist after recovery. Given the methodological difficulties associated with longitudinal studies, one promising option to address such obstacles going forward is by harnessing the advantages of ambulatory and web-based neurocognitive assessment methods that are more easily accessible to participants (e.g., Hansen, Haferstrom, Brunner, Lehn, & Håberg, 2015; Morrison, Simone, Ng, & Hardy, 2015; Sliwinski et al, 2018). …”

“…In this case, measurement procedure can be reduced to formalized assessment of errors in recognition, management or reproduction of virtual standards. Measurement results are presented as digital cognitive maps providing objective display of the cognitive system of a particular individual in a wide range of cognitive parameters [37][38][39].…”

The Persian adaptation of Baddeley’s 3-min grammatical reasoning test

“…Since administering long tests is not practical in research when other measures are also administered, the grammatical reasoning test serves as a very practical and timeefficient measure of Gf. For instance, Baddeley's grammatical reasoning test (along with Raven's matrices) has been included in the NeuroCognitive Performance Test (Lumos Labs, Inc.), a short, web-based cognitive assessment tool to assess functioning in working memory, fluid and logical reasoning, and some other cognitive abilities (Morrison, Simone, Ng, & Hardy, 2015).…”
