Brief Summary
This trial explores the use of immersive virtual reality (VR) nature-based experiences as a supplementary treatment for depression in individuals with progressive multiple sclerosis (MS). This study will evaluate the feasibility and efficacy of at-home VR deployment using the Apple Vision Pro, an advanced device that offers enhanced resolution, immersion, and usability compared to earlier VR systems. The study hypotheses include:
- The integration of VR nature-based experiences with standard care will be feasible, acceptable, and will result in greater reductions in depressive symptoms compared to standard care or VR-only interventions.
- The integration of VR nature-based experiences with standard care will result in greater reductions in stress and anxiety, better sleep, less insomnia, and improved fatigue compared to standard care alone or VR-only interventions.

Outcome Measures
Primary Outcomes (9)
Changes to the Patient-Reported Outcomes Measurement Information System (PROMIS) Depression short form 8b scores
This is an 8-item evaluating various aspects of depression, including negative mood, anhedonia, feelings of worthlessness, and cognitive impairments. Each item is rated on a 5-point Likert scale ranging from never (1) - always (5). Scores range from 8-40 with a higher score indicating greater symptom severity.
Baseline, 9-10 weeks and 20-21 weeks
Virtual Reality (VR) Sessions completed over 8 weeks
A benchmark of 70% will indicate adequate feasibility and acceptability.
8-week VR intervention
Qualitative feedback on the VR Neuroscience Questionnaire during the intervention (groups 1 and 3)
The modified scale for this project uses 10 questions that participants will answer about the VR experience, rated from 1 (extremely low or extremely difficult) to 7 (extremely high or extremely easy). The scores range from 10 to 70, with higher scores indicating greater experience. A benchmark of 70% indicates adequate feasibility and acceptability, with participant satisfaction ratings above 80%.
1-8 weeks (during VR)
Qualitative feedback with Semi-structured interviews for participants that received VR
Semi-structured interviews with 20 random participants (6-7 from each group) who received the VR treatment to capture participants' subjective experiences at the midpoint and end of the intervention. The interview questions will focus on emotional changes, engagement levels, and feedback on the intervention's implementation.
Weeks 9-10, Weeks 20- 21
Enrollment rate
Feasibility will be assessed via enrollment. Recruitment will be quantified by enrollment rates relative to the number of eligibility screenings.
Recruitment period (2 years)
Retention rates
Feasibility: Retention will be evaluated through the percentage of participants who complete the entire study duration, targeting a benchmark of at least 70%.
Baseline - 21 weeks
Adherence to VR intervention
Feasibility: Adherence to 5-15-minute sessions 3 times per week over 8 weeks
8-week VR intervention

Study Arms (3)
Virtual reality plus standard care (SC) then SC alone - randomized group
EXPERIMENTALParticipants in this group are maintained on antidepressants or psychotherapy and will receive VR nature sessions alongside participants' current depression treatments. This will be followed by a 1-week washout period, after which they crossover to standard care only.
Standard care alone then Virtual reality plus SC- randomized group
EXPERIMENTALParticipants in this group are maintained on standard depression treatments and will continue standard care for eight weeks. This will be followed by a 1-week washout period and crossover to VR plus Standard Care.
Virtual Reality - non-randomized group
EXPERIMENTALParticipants that are not receiving any treatment for depression will receive VR nature sessions for 8 weeks without depression treatments for eight weeks followed by 1 week washout and 8 weeks of no VR.
Interventions
Participant will have 8 weeks of immersive VR nature-based experiences. Participants are expected to use the VR headset three times per week. Headsets will contain a prototype application (app) developed by Explore POV. This app will include approximately one hour of footage showcasing 15-25 different nature experiences, that will shuffle every time participants access it. Participants will have the option to choose between 5, 10, or 15 minutes, sessions while answering weekly surveys regarding their experiences.
Participants that are in the randomized groups will continue on antidepressants or psychotherapy during the study per their standard care. Participants in the non-randomized group don't receive any treatment for their depression and will continue not to receive anything for this during the study.
Eligibility Criteria
You may qualify if:
- Confirmed diagnosis of progressive Multiple Sclerosis (MS, primary or secondary) by a neurologist or an MS center
- Patient-Reported Outcomes Measurement Information System (PROMIS) Depression T-scores \>55 at baseline
- Ability to provide informed consent and participate in VR sessions at home
- For Some Participants (Groups 1 and 2) currently receiving antidepressant or psychotherapy treatments (Selective Serotonin Reuptake Inhibitors (SSRIs), Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs), or psychotherapy) for the management of depression
You may not qualify if:
- Severe cognitive impairments or visual deficits that may interfere with VR use, including contraindications like agoraphobia, claustrophobia, or motion sickness
- Current participation in other clinical trials targeting depression
- Severe psychiatric conditions that require hospitalization, or suicidal ideation, passive or active, psychosis, or active substance and alcohol abuse (score greater than 1 on CAGE (Cut down, Annoyed, Guilty, Eye-opener) Adapted to Include Drugs (CAGE-AID))
- Another neurological or autoimmune disease per protocol
- Participants that require vision correction, unless that vision correction is mild (± 1), or the participant has prescription contact lenses.
