Abstract
Background and objectives

The chronic otitis media questionnaire-12 (COMQ-12) and chronic otitis media benefit inventory (COMBI) aim to assess the quality of life related to chronic otitis media or its surgical treatment. The objective of this study was to validate the Spanish adaptation of the COMQ-12 and COMBI.

Patients and methods

Multicentre prospective instrument validation study. guidelines for the cross-cultural adaptation process were followed. The psychometric properties of the Spanish versions (“COMQ-12-Spa” for “COMQ-12-Spanish” and “COMBI-Spa” for “COMBI-Spanish”) were assessed in 25 consecutive adults undergoing tympanoplasty and in a separate cohort of 25 unaffected adults.

Results

COMQ-12-Spa: test–retest reliability, r=0.98; internal consistency reliability, α=0.92. Item-subscale and item-total coefficients, ≥0.40. Between-group discrimination, p<0.0001. COMBI-Spa: internal consistency, α=0.96. A high-intensity relationship between the variables was shown, ≥0.40. Correlation between the COMBI-Spa and the Spanish Glasgow Benefit Inventory (GBI), r=0.89; p<0.01.

Conclusion

Psychometric testing of the Spanish versions of the COMQ-12-Spa and COMBI-Spa yielded satisfactory results, thus allowing pre- and postintervention assessment of the subjective severity of chronic otitis media in adult patients.

Resumen
Antecedentes y objetivo

El Cuestionario de otitis media crónica-12 (COMQ-12) y el Inventario de beneficios en otitis media crónica (COMBI) valoran la calidad de vida relacionada con la otitis media crónica o su tratamiento quirúrgico. El objetivo del estudio fue validar la adaptación española de los originales británicos.

Pacientes y métodos

Estudio multicéntrico prospectivo de validación de instrumento. Se siguieron las pautas para el proceso de adaptación transcultural. Las propiedades psicométricas de las versiones españolas, COMQ-12-Spa y COMBI-Spa, fueron evaluadas en 25 adultos consecutivos intervenidos de timpanoplastia y en una cohorte separada de 25 adultos sanos.

Resultados

COMQ-12-Spa: fiabilidad test-retest, r=0,98; consistencia interna, α=0,92; coeficientes ítem-subescala e ítem-total, ≥0,40; discriminación entre grupos, p<0,0001. COMBI-Spa: consistencia interna, α=0.96. Se encontró una relación de intensidad elevada entre las variables, ≥0,40. Correlación entre COMBI-Spa y Glasgow Benefit Inventory español (GBI), r=0,89; p<0,01.

Conclusiones

Las pruebas psicométricas de las versiones españolas COMQ-12-Spa y COMBI-Spa ofrecieron resultados satisfactorios, lo que permite la valoración pre y postintervención de la severidad subjetiva de la otitis media crónica en pacientes adultos.
