Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The VR group receives immersive VR sessions using the SilVR Adventures platform. The video group receives non-immersive video sessions with similar content. The usual care group receives no additional intervention.
Assessments are conducted at baseline, immediate post-intervention, and 3 months post-intervention to measure changes in depression, anxiety, loneliness, quality of life, and other outcomes. The intervention dosage will be 4 weeks (1 sessions/week; 30 min/session).
Secondarily, the study explores differences in effectiveness between caregivers and homebound older adults, and potential moderators or mediators such as baseline health status, technological literacy, and social support.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
CRs are assessed for cognitive function (using Mini-Mental State Examination - MMSE) and other health indicators. CGs are assessed for mental health, quality of life, and caregiving burden.
Participants are randomized into three groups: VR intervention (n=30 dyads), video control (n=30 dyads), or usual care (n=30 dyads). Randomization is stratified by CG age (\<60 vs. ≥60) and CR cognitive status (MMSE \<24 vs. ≥24).
As the intervention, the VR group receives 4 weekly 30-minute sessions of immersive VR experiences (e.g., virtual travel and social activities) facilitated by trained research staff. The video group receives 4 weekly 30-minute sessions of non-immersive videos with similar themes, also facilitated. The usual care group receives no additional intervention beyond community services.
At the end of the intervention, participants complete assessments again to measure changes in physical and mental health.
All participants will be contacted for follow-up assessment 3 months after the completion of intervention.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
VR Intervention Group
Caregivers and homebound older adults will receive 4 weeks of VR-based respite sessions.
VR-based Respite
Caregivers and homebound older adults will receive 4 weeks of VR-based respite sessions. 4 weeks (1 session/week; 30 min/session) of immersive VR sessions using SilVR Adventures platform. Sessions include virtual travel destinations (e.g., cities, natural wonders) and social activities (e.g., group tours). Facilitated by trained research staff, with 5-10 minutes viewing and 20 minutes reflection/discussion.
Video Control Group
Caregivers and homebound older adults will receive 4 weeks of video-based respite sessions.
Video-based Respite
Caregivers and homebound older adults will receive 4 weeks of video-based respite sessions. 4 weeks (1 session/week; 30 min/session) of non-immersive video sessions with content similar to VR themes (e.g., landscapes, cultural events). Facilitated by trained research staff, with post-video discussion. EEG data collected during viewing to assess emotional states.
Usual Care Group
Caregivers and homebound older adults will receive no additional intervention.
No interventions assigned to this group
