Multidimensional assessment of virtual reality applications in clinical neuropsychology: The 'VR-Check' protocol

The experimental features of Virtual Reality (VR) applications in clinical neuropsychology are only inadequately captured by classical psychometric quality criteria, warranting an extended paradigm evaluation framework. Here we propose such a framework by means of a multidimensional checklist (VR-Check). Evaluation dimensions encompass cognitive domain specificity, ecological relevance, technical feasibility, user feasibility, user motivation, task adaptability, performance quantification, immersive capacities, training feasibility, and predictable pitfalls. Assessment along these VR-Check dimensions enables a systematic and comparative evaluation of neuropsychological VR applications, as we illustrate here for the exemplary case of assessing spatial cognition with immersive VR.
