[Validation of a Spanish questionnaire to evaluate habits, attitudes, and understanding of exposure to sunlight: "the beach questionnaire"]. / Validación de un cuestionario en español sobre comportamientos, actitudes y conocimientos relacionados con la exposición solar: <>

BACKGROUND: Questionnaires are the usual method for investigating sun-related behavior. However,such tools must be validated through evaluation of their measurement properties.The aim of the present study was to assess the validity and reliability of a Spanish questionnaire evaluating habits, attitudes, and understanding of exposure to sunlight. PATIENTS AND METHODS: In a cross-sectional study, the questionnaire was administered to a sample of 422 participants found on beaches. For the test-retest analysis, 70 hospital-based health professionals were interviewed on 2 separate occasions.The construct validity, internal consistency, and reproducibility were analyzed. RESULTS: Factorial analysis of the principal components confirmed the construct validity with commonalities and factor saturations > 0.50, and revealed multiple dimensions with Cronbach a values > 0.70.The items on habits and understanding showed intraclass correlation and d coefficient values > 0.70, but those on attitude had lower stability values (0.50-0.80). CONCLUSIONS: This is the first Spanish questionnaire with demonstrated validity and reliability for evaluating habits, attitudes, and understanding of exposure to sunlight. It will be a useful instrument for future epidemiologic studies and research into the prevention of skin cancer in Spain.

Validación de un cuestionario en español sobre comportamientos, actitudes y conocimientos relacionados con la exposición solar: «Cuestionario a pie de playa» / Validation of a Spanish Questionnaire to Evaluate Habits, Attitudes, and Understanding of Exposure to Sunlight: 'The beach questionnaire'

Introducción. Los cuestionarios son el método habitual de investigación de las conductas relacionadas con la exposición solar. Sin embargo, para que un instrumento sea válido debe acreditar sus propiedades de medición. El objetivo del presente trabajo fue evaluar la validez y la fiabilidad de un cuestionario en español sobre comportamientos, actitudes y conocimientos relacionados con la exposición solar en la playa. Pacientes y método. Se realizó un estudio de corte transversal administrándose el cuestionario a una muestra de 422 participantes a pie de playa. Para la prueba del test-retest se encuestó a 70 participantes del medio hospitalario en dos ocasiones diferentes. Se analizaron la validez, la consistencia interna y la reproducibilidad de los ítems del instrumento. Resultados. El análisis factorial de los componentes principales mostró valores de comunalidades y saturaciones factoriales > 0,50, y reveló la presencia de múltiples dimensiones que presentaron valores de coeficiente alfa de Cronbach > 0,70. Los ítems de comportamientos y conocimientos evidenciaron coeficientes de correlación intraclase y delta > 0,70. Los ítems del apartado de actitudes mostraron valores moderados de estabilidad (0,50-0,80). Conclusiones. Se presenta el primer cuestionario sobre comportamientos, actitudes y conocimientos relacionados con la exposición solar, elaborado en español, con garantías de validez y fiabilidad. Este instrumento constituirá una herramienta de utilidad en la investigación epidemiológica y del ámbito de la prevención primaria del cáncer de piel en España (AU)

[Clinical and performance results of functional endoscopic sinus surgery]. / Resultados clínicos y asistenciales de la cirugía endoscópica nasosinusal.

Our aim was to know the clinical performance and management results of Functional Endoscopic Sinus Surgery (FESS) in Spanish hospitals. We sent a survey on the use and results of FESS to 160 Spanish public hospitals in June of 2002, obtaining a response rate of 69%. 82.9% of the interviewed hospitals carried out FESS and 17.1% of the remaining used the classic techniques of approaching the paranasal sinuses. The reported length of stay in hospital was 1.4 days for the FESS and 2.4 for the traditional surgery. The surgical time was 15 minutes shorter for the CENS, and the rate of recurrence was 16% less than for the classic surgery. As years of experience in the practice of the CENS go by, the surgical times tend to decrease, that didn't happen with the rate of recurrence. In conclusion, we consider that FESS seems to improve the analyzed clinical performance and assistential results.

Resultados clínicos y asistenciales de la cirugía endoscópica nasosinusal / Clinical and performance results of functional endoscopic sinus surgery

Nuestro objetivo fue conocer los resultados clínicos y asistenciales de la Cirugía Endoscópica Nasosinusal (CENS) en hospitales españoles. Enviamos una encuesta sobre su utilización y resultados a 160 hospitales públicos españoles en junio de 2002, obteniendo una tasa de respuesta del 69 por ciento de los centros. El 82,9 por ciento de los hospitales encuestados realizaba CENS y el 17,1 por ciento restante utilizaba las técnicas clásicas de abordaje de senos paranasales. La estancia media hospitalaria declarada fue de 1,4 días para la CENS y 2,4 para la cirugía tradicional. El tiempo quirúrgico medio fue 15 minutos menor para la CENS, obteniéndose un 16 por ciento menos de recidivas frente a la cirugía clásica. A más años de experiencia en la práctica de la CENS, los tiempos quirúrgicos tienden a reducirse, lo que no ocurrió con el porcentaje de recidivas. En conclusión, consideramos que la CENS parece mejorar los parámetros clínicos y asistenciales analizados (AU)
