Fundamentos: En la última década se han desarrollado diversas medidas de calidad de vida relacionada con la salud para uso exclusivo en niños/as y adolescentes. No obstante, existen pocos instrumentos de estas características adaptados en España. El Vecú et Sante Perçue de l'adolescent (VSP-A) es un instrumento genérico de calidad de vida relacionada con la salud para adolescentes de 11 a 17 años desarrollado en Francia. El objetivo de este estudio fue adaptar al español el VSP-A, como primera fase para la obtención del cuestionario. Métodos: Se adaptó la versión del VSP-A de 39 preguntas siguiendo la metodología de traducción directa e inversa incluyendo: 2 traducciones al español, puntuación del grado de dificultad (0 min-10 máx) y clasificación de equivalencia semántica y cultural, 2 reuniones y discusión en paneles de adolescentes, así como reuniones de consenso del equipo de investigación. Finalmente se realizó una traducción inversa (retro-traducción) al francés y se administró la versión final pre-test en la prueba piloto. Resultados: La mayoría de las preguntas se clasificaron como equivalentes (24 sobre 39). Tras las reuniones con adolescentes se modificaron algunas preguntas. Tras la retro-traducción, 3 preguntas necesitaron cambios menores. Conclusiones: La versión española del VSP-A parece semántica y culturalmente equivalente a la versión original en francés y adecuada para adolescentes en España. La sencillez de las preguntas, los comentarios de los adolescentes y la participación de los autores originales en el proceso de adaptación ha permitido obtener una versión pre-test adecuada. La siguiente fase del estudio es la comprobación de la fiabilidad y validez. Se espera que el VSP-A sea de utilidad para medir la calidad de vida relacionada con la salud en encuestas de salud o como instrumento de cribado en colegios o centros de atención primaria en nuestro medio.

Objective: The Short Form-36 Health Survey (SF-36) is one of the most widely used and evaluated generic health-related quality of life (HRQL) questionnaires. After almost a decade of use in Spain, the present article critically reviews the content and metric properties of the Spanish version, as well as its new developments., Methods: A review of indexed articles that used the Spanish version of the SF-36 was performed in Medline (PubMed), the Spanish bibliographic databases IBECS and IME. Articles that provided information on the measurement model, reliability, validity, and responsiveness to change of the instrument were selected., Results: Seventy-nine articles were found, of which 17 evaluated the metric characteristics of the questionnaire. The reliability of the SF-36 scales was higher than the suggested standard (Cronbach's alpha) of 0.7 in 96% of the evaluations. Grouped evaluations obtained by meta-analysis were higher than 0.7 in all cases. The SF-36 showed good discrimination among severity groups, moderate correlations with clinical indicators, and high correlations with other HRQL instruments. Moreover, questionnaire scores predicted mortality and were able to detect improvement due to therapeutic interventions such as coronary angioplasty, benign prostatic hyperplasia surgery, and non-invasive positive pressure home ventilation. The new developments (norm-based scoring, version 2, the SF-12 and SF-8) improved both the metric properties and interpretation of the questionnaire., Conclusions: The Spanish version of the SF-36 and its recently developed versions is a suitable instrument for use in medical research, as well as in clinical practice.

Background: Different measures of health related quality of life for use exclusively in children and adolescents have been developed over the last ten years. However, few instruments of this type have been adapted in Spain. The VSP-A is a generic health related quality of life measure for adolescents aged 11-17 developed in France. The objective of this study was to adapt the VSP-A into Spanish as a first step towards obtaining this questionnaire., Methods: The version of the VSP-A including 39 questions was adapted following the forward-backward translation methodology, including two translations into Spanish, scoring of difficulty (0 min-10 max.) and classification of semantic and conceptual equivalence, two panel discussions with adolescents, as well as meetings of consensus with the original authors. Finally, a backward translation (translation back into the original language) was carried out into French, and the final pre-test version was administered in a pilot test., Results: Most of the questions were classified as equivalent (24/39). Following the meetings with adolescents, changes were made in some questions. After the back-translation into French, three questions required some minor changes., Conclusions: The Spanish version of the VSP-A seems to be semantically and culturally equivalent to the original version and suitable for adolescents in Spain. The inclusion of easy statements in the original version, the comments of the adolescents and the involvement in the adaptation process of the original authors has offered the possibility of achieving a suitable pre-test version. The next phase of the study will involve the questionnaire's reliability and validity testing. The VSP-A is expected to be useful for measuring the health-related quality of life in health surveys or as a screening tool in schools and primary care centers in Spain.
