About this trial
Participants with chronic back pain will complete an online Qualtrics eligibility survey. After signing a consent form, eligible participants enter a two-week baseline period ("Baseline Period"), during which they complete two assessments of the Primary and Secondary Outcome Measures and Potential Mediators. After the baseline period, participants are randomized into a Virtual Reality group: VR Distraction-based Therapy or VR Skills-based Therapy, with a 1:1 allocation ratio of participants to each treatment. Both groups receive education on pain neuroscience and complete training on the use of the VR hardware and software. Next, both groups complete an intervention for 8 weeks ("Treatment Period"), after which they return the VR equipment. Several surveys are administered online during the Treatment Period. After the Treatment Period, both groups complete three post-treatment surveys at weeks 8, 20, and 32.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers

Treatments tested in this trial
Skills-based Virtual Reality Therapy
Device1. A 34-minute education video session on the science behind chronic pain and the scientific principles of the therapy. 2. VR skills-based therapy: a virtual reality therapy consisting of different psychological training exercises
Distraction-based Virtual Reality Therapy
Device1\. A 7-minute education video session on the science behind pain-focused attention and distraction. 2. VR distraction-based therapy: a virtual reality therapy that encourages passive attention and minimizes external cognitive demands.
Treatment groups
Trial outcomes
Primary outcomes
Change in Pain Intensity and Interference
Brief Pain Inventory-short form (BPI-SF). Measured on a Scale of 0 to 10, 0 = no pain, 10 = worst pain imaginable.
Secondary outcomes
Pain Interference
Brief Pain Inventory-short form (BPI-SF). Measured on a Scale of 0 to 10, 0 = no interference, 10 = severe interference.
Disability
Oswestry Low Back Pain Disability Questionnaire (OLBPQ). Measured on a scale of 0-100%, 0-20% = minimal disability, 80-100% = patients are bed-bound or exaggerating symptoms.
Physical Function
Physical Function (PROMIS). 5-point Likert scale: 5 = without any difficulty, 1 = unable to do (worse outcome).
Sleep Disturbance
Sleep Disturbance (PROMIS). 5-point Likert scale: 1 = very good, 5 = very poor (worst outcome).
Other outcomes
Cybersickness
Single item questionnaire: "Did you experience any motion sickness or nausea while using VR?". 4-point Likert Scale: 0 = never, 3 = always (worst outcome).
Global Improvement
Patient's Global Impression of Change (PGIC). 10-point Likert scale: 0 = much better, 10 = much worse (worst outcome).
Treatment Satisfaction
Treatment satisfaction (single item). 7-point Likert scale: extremely satisfied, extremely dissatisfied (worst outcome).
System Usability
System usability (SUS). 5-point Likert scale: 1 = strongly disagree, 5 = strongly agree.
