Feasibility of a novice electronic psychometric assessment system for cognitively impaired.

The assessment and rehabilitation of patients with cognitive dysfunction is a field that currently requires assistive technology. While the paper-and-pencil test, such as the line tracing test, is one of the commonly used assessment methods for cognitive dysfunction, accuracy, and time-consuming assessment process needed technological application. The aim of this study was therefore to establish a computer-based real-time assessment system (e-system) for patients without compromising the usefulness of the conventional paper-and-pencil based user tools with 50 healthy participants. The comparison of the e-system with the golden-standard assessment (evaluator) results showed high concordance correlation coefficients of 0.89 and 0.87 and small effective sizes of 0.27 and 0.27 between two repeated measures. The Bland-Altman plots also showed smaller degree of error and greater repeatability in comparison to the repeated measures. Moreover, the accuracy rates of 96.5% and 96.4% were shown. The results indicated feasibility of the novice e-system. The e-system may assist rehabilitation specialists to assess and diagnose patients with cognitive dysfunction. This system can be applied to a range of assessment and rehabilitation modalities based on pen and paper. It can also be used for various patients such as those with Parkinson disease, stroke, or different forms of brain lesions.
