Introduction: Epilepsy has a high impact on the quality of life of the child, so it is important to have validated and consistent instruments to evaluate it.
Aim: To compare the validity and reliability of a new quality of life scale for paediatric epileptic patients (ECAVIPEP) from a Mexican hospital against the widely validated CAVE scale.
Patients and methods: A comparative study was conducted to test the validity and realiability of a new scale for evaluating epilepsy in children. The test, conducted on a sample of epileptic children between 4 and 10 years of age, involved the application of a new quality of life scale and comparing it with the widely validated CAVE scale. Cronbach's alpha and Spearman's rho were used for validity and consistency.
Results: There were 114 patients, 72 (63.2%) male and 42 (36.8%) female. Internal consistency yielded a Cronbach's alpha value of 0.673. For the analysis of convergent validity, scores obtained by CAVE and ECAVIPEP Spearman's rho correlation was 0.670 (p lower than 0).
Conclusions: ECAVIPEP scale is valid and consistent to assess epilepsy in children from 4 to 10 years.
Objetivo Comparar la validez y consistencia de una nueva escala de calidad de vida para pacientes epilépticos pediátricos (ECAVIPEP) de un hospital mexicano con la escala CAVE ampliamente validada.
Pacientes y métodos Estudio comparativo, en el que se analiza la validez y consistencia de una nueva escala para evaluar la epilepsia en niños. Se realizó en niños epilépticos de 4-10 años mediante la aplicación de una escala de calidad de vida, comparándola con la escala CAVE ampliamente validada. Se utilizó el alfa de Cronbach y la rho de Spearman para la validez y la consistencia.
Resultados Fueron 114 pacientes, 72 (63,1%) niños y 42 (36,8%) niñas. La consistencia interna dio un valor del alfa de Cronbach de 0,673. Para el análisis de validez convergente, comparando las puntuaciones obtenidas por la CAVE y por la ECAVIPEP, se obtuvo una rho de Spearman de 0,670 (p < 0).
Conclusión La ECAVIPEP es una escala válida y consistente para la evaluación en niños de 4-10 años con epilepsia.
