Fiabilidad y validez del cuestionario de salud y calidad de vida para adolescentes Vecú et Santé Perçue de l'Adolescent (VSP-A)

Abstract

Objective. To assess the psychometric properties of the Spanish version of the Vécu et Santé Perçue de l'Adolescent (VSP-A) in terms of reliability and validity. Design. Cross-sectional study. Setting. Pilot study parallel to the European Kidscreen project. Two secondary schools, one public and one private, were selected for their suitability in Barcelona and Gerona (Catalonia, Spain). The sample unit was the classroom. Participants. A sample of 354 adolescents aged 12 to 18 years old was selected. Main measurements. The Spanish VSP-A questionnaire was administered, and again a week later to check its test-retest stability. The KINDL questionnaire was administered in parallel. Results. The response rate was 82% (n=291). The Spanish version of the VSP-A showed good internal consistency and acceptable test-retest reliability (Cronbach's α: 0.69-0.92, intraclass correlation coefficient [ICC]: 0.69-0.74) in most domains. Domains measuring a similar concept in the VSP-A and KINDL had closer correlation coefficients than those measuring different constructs (P
