Samenvatting

With the rising adoption of virtual reality (VR) in health care, research publications on the topic are increasing rapidly. Guidance on reporting VR interventions is limited, which risks misinterpretation of findings, inappropriate data synthesis in reviews and meta-analyses, and reduced reproducibility. This could also result in possible misuse of VR interventions and might hinder further implementation in clinical practice. The aim of this study was to develop a reporting guideline for therapeutic, immersive VR interventions using head-mounted displays in scientific publications. To reach this aim, we intended to achieve expert consensus on key items and categories for reporting these interventions. We conducted a three-round, modified, online Delphi study with a validation meeting to develop a VR intervention reporting guideline. Participants were international experts in therapeutic VR research, working as academic or industrial researchers. Convenience, purposive, and snowball sampling were used to recruit participants. Consensus was defined a priori as ‡75% agreement on each reporting item and category. Of the 280 invited experts, 61 participants (22%) completed all three rounds of this Delphi study. Participants (32 females [52%]) had an average of 6 years’ experience with VR research and diverse backgrounds in VR research settings and disciplines. The final consensus-based VR intervention reporting guideline consists of 16 reporting items divided into six categories (i.e., theory, content, deployment, development, safety, and context). The INVIRTUE intervention reporting guide line provides a framework for describing therapeutic VR interventions. Using this tool may enhance the uniformity and completeness of VR intervention reporting and support study replicability and scientific progress. The reporting guideline will also facilitate efficient empirical comparison across existing VR interventions and ultimately contribute to the appropriate use and effective implementation of therapeutic VR in clinical practice.
