Background and aims: *Low physical health is one consequence that chronic pain encompasses. To improveeffectiveness of Interdisciplinary pain rehabilitation programs (IPRP) theeVISualisation of physical activity and pain (eVIS) intervention was developed. Thepurpose of this study was to evaluate eVIS validity by the aspects of content validityand clinical feasibility in IPRP-context.Methods: *This observational study was performed in 3 phases. Twenty-two field experts (patients,caregivers, researchers) participated, and provided quantitative scores and qualitativecomments on eVIS and its included elements (data collection, visualization,communication). In phase 1, ratings on a four-point Likert scale of each element´scontent validity (relevance, simplicity, safety) were collected through digitalquestionnaires. Three iterative assessment loops were completed, each followed byconsensus panel protocol revisions. Item-level content validity index (I-CVI), averageand overall CVI were calculated, and free-text comments were analyzed. In phase 2,ratings of content validity and elements’ clinical feasibility categorized in 5 focus areas(acceptability, demand, implementation, limited efficacy, practicality), were collectedfrom patients and caregivers after 2-3 weeks test trial. Phase 3 involved follow-up focusgroup interview with caregivers on specific ratings, as well as interviews with expertsin clinical pain management pharmacology.Results: *CVI for relevance, simplicity and safety improved over time and were all rated abovecut-off (0.78). Revisions were mainly made in the visualization element. In phase 2,participants rated eVIS as relevant and feasible to use in clinical IPRP-context.Conclusions: *Patients, caregivers, and researchers found eVIS valid in IPRP-context. Methodicalvalidation was essential to ascertain eVIS’ substantiality before clinical trial.
