Abstract

Background. Quality of life questionnaires provide valuable information in assessing the effects of health interventions and public health campaigns. In the Philippines, we only have a few validated questionnaires targeted specifically for children.

Objective. To translate to Filipino and validate the translated Impact of Vision Impairment for Children Questionnaire (IVI_C).

Methods. This is a translation and validation study of the IVI_C. The IVI_C was translated following international guidelines of forward–translation and back-translation methods. After completion of the Filipino IVI_C version, pretesting was performed on school-aged children 8 to 18 years old through convenience sampling in the outpatient department and Pediatric Ophthalmology and Motility Clinic at Sentro Oftalmologico Jose Rizal, Philippine General Hospital from January 1 to August 31, 2018.

Results. We included 130 participants in the study. The calculated Cronbach’s alpha coefficient of 0.88 for the translated Filipino version of the IVI_C suggested high reliability and internal consistency. Rasch analysis showed comparability of the Filipino translation to the original English version of the questionnaire.

Conclusion. Our study showed that the Filipino version of IVI_C questionnaire was of high reliability and validity.
