Development and Validation of EVANpedia for the Assessment of Perioperative Experience in Pediatric Patients
Authors' conclusion
EVANpedia is a psychometrically robust self-reported instrument for assessing the perioperative experience in children and adolescents.
Study context
- Population
- Children and adolescents (7 to 17 yr old) within 24 h after surgery and anesthesia, four anesthesia departments4 anesthesia departments
- Participants
- 600 children
- Outcome
- Psychometric properties of EVANpedia, a self-reported instrument of perioperative experience (structure, unidimensionality, reliability, convergent and external validity)
- Follow-up
- Within 24 h after surgery

Further findings
| Outcome | Reported disappointment | Other children | P value |
|---|---|---|---|
| Overall EVANpedia score by reported disappointment with perioperative experienceSignificantly lower overall EVANpedia scores | 50.1 ± 12.1 | 62.8 ± 15.1 | P < 0.001 |
- Overall EVANpedia score by reported disappointment with perioperative experience — Children reporting disappointment with perioperative experience
- Nine percent
Responsiveness (sensitivity to clinical change)
- Overall and all dimensional EVANpedia scores showed excellent sensitivity to clinical change
Convergent validity
- Correlations between EVANpedia scores and all concurrent measures supported convergent validity
