ABSTRACT
The Rey Auditory Verbal Learning Test (RAVLT) is a commonly used tool for evaluating verbal learning and memory in neuropsychological assessments. In recent years, we developed a Virtual Reality (VR) adaptation of the RAVLT (VR-RVLT), aiming for increased ecological validity compared to the traditional pen and paper gold standard (GS-RAVLT). Following validation in healthy cohorts, the VR-RAVLT was validated with thirty individuals with Parkinson's Disease (PD) that completed both the GS-RAVLT and the VR- RAVLT. Validity of the VR-RAVLT was evaluated by assessing its construct and discriminant validity, and test-retest reliability, in comparison to the GS-RAVLT. Results of the PD participants were compared to those of 46 previously recruited healthy participants with comparable age and level of education. Main outcome measures derived from the remembered items on the test lists, exhibited significant and comparable correlations between VR-RAVLT and GS-RAVLT, both among healthy participants and PD participants. Likewise, serial position effects were similar for both formats amog the PD participants. Additionally, both formats showed similar discriminatory ability between healthy controls and PD participants, as well as comparable test-retest reliability measures. Taken together, the results suggest that the VR-based RAVLT is equally effective in measuring verbal memory capabilities in individuals with PD as compared to the GS-RAVLT. Certain results indicate that the virtual reality version has the capability to encompass additional factors that might impact memory performance, thereby suggesting an enhanced ecological validity.
