Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants will experience one 10-minute nature-based virtual reality session conducted in person at each individual’s rest home facility. They will be fitted with a Meta Quest 3 headset to wear for the 10-minute duration. The VR experience features footage of New Zealand nature scenes accompanied by meditative music blended with the natural sounds of each scene. This footage can be accessed on youtube (https://www.youtube.com/watch?v=pEO4my44oqw). Prior to the VR experience, participants will complete a 40-minute baseline questionnaire and via an iPad watch a 4-minute pre-recorded video introducing and encouraging the experience of awe. Immediately following the VR session, a follow-up questionnaire taking approximately 30 minutes will be completed. Finally, one week later, the final follow-up questionnaire will be completed, taking 35 minutes either in-person or online. The session will be conducted by the student researcher completing her thesis in Health Psychology. The VR experience will be conducted with participants either seated in a sturdy chair or in bed in a sitting-up position. The intervention will be delivered face to face to each participant individually. Adherence to the VR experience will be monitored by direct observation from the researcher.

Comparator / control treatment
Participants will experience one 10-minute informational virtual reality session conducted in person at each individual’s rest home facility. The VR experience features static footage of an individual speaking about virtual reality against a plain background. Prior to the VR experience, participants will complete a 40-minute baseline questionnaire and after wait quietly for a four-minute duration as the researcher leaves the room. Immediately following the VR session, a follow-up questionnaire taking approximately 30 minutes will be completed. Finally, one week later, the final follow-up questionnaire will be completed, taking 35 minutes either in-person or online. The session will be conducted by the student researcher completing her thesis in Health Psychology. The VR experience will be conducted with participants either seated in a study chair or in bed in a sitting-up position. The intervention will be delivered face to face to each participant individually.

Efficacy
Statistical methods / analysis
The required sample size was calculated using GPower 3.1 software for a repeated measures ANOVA with a within-between interaction. Based on an alpha level of .05, power of .80, a medium effect size (f = 0.25), three time points (T1, T2, T3), two groups (intervention vs. control), a correlation among repeated measures of 0.5, and a nonsphericity correction of 0.75, a minimum of 34 participants is required. This estimate was informed by a pilot study that assessed the impact of the same virtual reality nature intervention on connectedness (r = .59), although a more conservative effect size was chosen due to limitations in the pilot study design. To allow for 20% attrition, the final target sample size is 40 participants (20 per group).

Data will be analyzed using SPSS. A factorial mixed ANOVA will evaluate changes over time in connectedness (primary outcome), with group as the between-subjects factor. The same approach will be used for secondary outcomes. If assumptions are violated, robust ANOVA methods will be applied. Group differences in awe will be tested using t-tests or Mann-Whitney U tests. Exploratory mediation analyses will examine awe as a mediator of intervention effects.
