Overview

Validation study demonstrates reliability of the Spanish Pediatric Refractive Error Profile in children wearing glasses, indicating its utility for evaluating vision-related quality of life.

Key Points

To translate, culturally adapt, and evaluate the initial reliability and validity of the Pediatric Refractive Error Profile questionnaire in Spanish for children wearing spectacles.
Translated and culturally adapted the questionnaire using a standardized five-step protocol.
Administered the Spanish version to 124 children aged 8–14 years with refractive errors and at least one year of spectacle wear.
Assessed internal consistency with Cronbach's alpha, test-retest reliability with intraclass correlation coefficients in 18 participants, and validity via clinical visual parameters and a visual analogue scale.
Internal consistency was strong across all 10 scales (Cronbach's alpha range: 0.754 to 0.918), and test-retest reliability demonstrated moderate to excellent stability (ICC range: 0.541 to 0.921).
Item-scale correlations exceeded 0.40, with visual acuity correlating significantly with vision-related scales and visual analogue scale scores associating with appearance, satisfaction, and activity scales.
Participants with visual acuity deficits scored significantly lower across multiple quality-of-life domains compared to peers with better visual acuity.
