Development and validation of virtual reality-based Rey Auditory Verbal Learning Test

Area of Science:

• Neuroscience
• Psychology
• Virtual Reality Technology

Background:

• Traditional neuropsychological tests can be adapted to virtual reality (VR) to improve ecological validity.
• VR allows for the simulation of real-world scenarios in a controlled environment.
• The Rey Auditory Verbal Learning Test (RAVLT) is a commonly used neuropsychological assessment.

Purpose of the Study:

• To translate and adapt the Rey Auditory Verbal Learning Test (RAVLT) into a virtual reality environment (VR-RAVLT).
• To validate the construct validity, age-related discriminant validity, and test-retest validity of the VR-RAVLT against the gold standard RAVLT (GS-RAVLT).

Main Methods:

• Developed a VR-RAVLT using a fully immersive VR system simulating a conversation with a secretary.
• Recruited 78 participants across different age groups to perform both GS-RAVLT and VR-RAVLT in a counterbalanced order.
• Utilized Pearson's correlation coefficients, serial position effects, receiver operating characteristic area under the curve, and intraclass correlation coefficients for validation.

Main Results:

• The VR-RAVLT demonstrated comparable construct validity to the GS-RAVLT.
• Discriminant and test-retest validities of the VR-RAVLT were also found to be similar to the GS-RAVLT.
• Results indicate that the VR-RAVLT and GS-RAVLT share similar psychometric properties.

Conclusions:

• The VR-RAVLT is a feasible adaptation of the traditional RAVLT, maintaining similar psychometric properties.
• The study suggests that the VR-RAVLT measures the same cognitive construct as the GS-RAVLT.
• This VR adaptation holds potential for future clinical diagnosis and treatment applications.
