RT Journal Article T1 Validity and reliability of Spanish PROMIS pediatric pain interference short form A1 Ceniza Bordallo, Guillermo A1 Gómez Fraile, Andrés A1 Martín Casas, Patricia A1 López De Uralde Villanueva, Ibai Julio AB Background: The goal of this study was to analyze psychometric properties of the Spanish PROMIS Pediatric Pain Interference short form (PROMIS-PPI) in a sample of Spanish children and adolescents.Methods: In a hospital pediatric sample itwas studied the structure scale (exploratory and confirmatory analysis), construct validity, convergent validity, and reliability (internal consistency).Findings: 163 children and adolescents (mean age 13.3 years; SD 2.01; 39.26% female) with and without chronic pain completed measures pertaining to their pain experience. Psychometric analysis showed the PROMIS-PPI Spanish version maintains the original one-factor model of the scale, excellent internal consistency (Cronbach's α coefficient 0.90 (95% CI 0.88–0.92)), and convergent validity (showed a positive, significant, and moderate magnitude correlation [r from 0.330 to 0.604] with pediatric quality of life, child and parent pain intensity, and showed a low correlation with the number of medical consultations in the last year).Discussion: The Spanish PROMIS-PPI scale is a valid and reliable tool. It is recommended for research and clinical care in pediatric populations.Application to practice: The results provide evidence that the Spanish version of PROMIS-PPI is valid and reliable tool. Health professionals who work with children in risk to develop persistent pain, will have access to short tool with highest evidence, for assess pain interference.
