Objective

Interventions to increase asthma knowledge enable children and/or their parents to acquire skills needed for the prevention and/or appropriate management of crises. Periods of illness caused by the disease can thereby be reduced. However, no validated instrument for quantifying knowledge of asthma is available in Spanish. The aim of the present study was to develop and validate an asthma knowledge questionnaire that could be self-administered by parents and/or persons charged with caring for asthmatic children.

Material and methods

The 17 items that make up the questionnaire were obtained on the basis of a review of the literature, focus group discussions, the professional experience of the researchers, and pilot studies. We evaluated the instrument's face, content, and concurrent validity and analyzed its factorial structure. The test-retest reliability of the questionnaire and its sensitivity to change were also assessed.

Results

A total of 120 pediatric patients with a mean (SD) age of 4.5 (3.7) years participated. Factor analysis demonstrated a probable structure of 3 factors that together explained 85% of the total variance in results. The opinion of an interdisciplinary group of experts on asthma confirmed the face validity of the instrument. The questionnaire's ability to distinguish between parents with high and low asthma knowledge demonstrated its concurrent validity. Test-retest reliability was demonstrated, as was sensitivity to change between 2 different testing moments.

Conclusions

The asthma knowledge questionnaire developed is useful and reliable for quantifying the baseline level of asthma knowledge of parents of asthmatic children as well as to assess the efficacy of an educational intervention aiming to increase knowledge and understanding of the disease.

Objetivo

Una intervención educativa destinada a aumen-tar el conocimiento acerca del asma permite a los niños y/o sus padres adquirir habilidades que les permitan prevenir y/o manejar adecuadamente las crisis asmáticas, disminuyendo la morbilidad producida por la enfermedad. Sin embargo, en nuestro medio no contamos con un instrumento validado que nos permita cuantificar el nivel de conocimiento de asma. El objetivo del presente estudio ha sido desarrollar y validar un cuestionario de conocimientos acerca del asma para ser cumplimentado por los padres y/o personas encargadas del cuidado de pacientes pediátricos asmáticos.

Material y métodos

LOS 17 ítems que conforman el cuestionario se obtuvieron de la revisión de la bibliografía, la realización de grupos focales, la experiencia profesional de los investigadores y la realización de pruebas piloto. Se evaluó la validez de apariencia, de contenido y de criterio concurrente del instrumento; asimismo se determinaron la estructura factorial, la fiabilidad test-retest y la sensibilidad al cambio del cuestionario.

Resultados

Se incluyó a 120 pacientes pediátricos con una edad promedio (± desviación estándar) de 4,5 ± 3,7 años. El análisis factorial demostró una estructura probable de 3 factores, que en conjunto explican el 85% de la varianza total de los resultados. La validez de apariencia y de contenido se basó en el concepto de un grupo multidisciplinario de expertos en el tema. La validez de criterio concurrente se demostró mediante la habilidad del cuestionario para distinguir a los padres con alto y con bajo conocimiento acerca del asma. Se demostraron además una adecuada fiabilidad test-retest y una adecuada sensibilidad al cambio al comparar la puntuación del cuestionario administrado en 2 ocasiones distintas.

Conclusiones

El cuestionario de conocimientos de asma desarrollado en el estudio es una herramienta útil y fiable para cuantificar el nivel basal de conocimiento acerca del asma en padres de niños asmáticos, así como para determi-nar la eficacia de una intervención educativa destinada a au-mentar el conocimiento y la comprensión de la enfermedad.
