Fibromyalgia is a chronic pain condition associated with reduced quality of life, psychological symptoms, cognitive impairment, and low adherence to exercise-based interventions. Immersive virtual reality (IVR) has gained attention as a rehabilitation approach; however, the relationship between user experience, adherence, and clinical outcomes remains unclear. This post hoc exploratory secondary analysis was derived from a randomized controlled clinical trial (NCT07605143) and included 16 women with fibromyalgia who completed a six-week IVR-based rehabilitation program. Associations between user experience, adherence, and clinical outcomes were explored among participants exposed to IVR. Quality of life was assessed using the Fibromyalgia Impact Questionnaire-Revised (FIQ-R), psychological symptoms using the Depression Anxiety Stress Scales (DASS-21), and user experience using the Player Experience of Need Satisfaction (PENS) questionnaire. Within-group changes were observed in FIQ-R scores (p = 0.001; d = 1.08) and DASS-21 stress levels (p = 0.025). Participants demonstrated favorable adherence and positive user experience. A significant correlation was identified between intuitive control and changes in depression scores (ρ = 0.63, p = 0.008). This exploratory analysis identified favorable user experience and adherence among women participating in an IVR-based rehabilitation program. However, due to the absence of a concurrent control group, no conclusions regarding treatment efficacy can be drawn. These findings should be considered hypothesis-generating.
