BACKGROUND: Vision Related Quality of Life (VRQoL) in visual impairment children was accessed in The IVI-C questionnaire was translated to many languages and validated in many countries such as China(1) , Germany(2) , India(3) and Australia(4) using different translation of the Impact Vision Impairment of Children (IVI_C) questionnaire. However, VRQoL in visual impairment children in Saudi Arabia (SA) was not accessed. This is because there is no Arabic valid tool in the literature that can be used to access VRQoL. Therefore, there is a need for Arabic valid and reliable instrument that can be used to assess VRQoL in children with visual impairment. AIM: The aim of this study was to test the validity and reliability of the Arabic version of the 23-item of IVI_C questionnaire on school-aged children with visual impairment in SA. METHODS: This is a cross sectional study conducted in many low vision clinics in Riyadh, SA. The questionnaire was administered face-to-face to seventy-seven children with visual impairment who aged was ranged between 8 to 18 years old. Visual examinations include distance and near visual acuity were measured for all the participants. Rasch analysis was used to test the reliability and validity of the translated questionnaire. RESULTS: The 23-item IVI-C questionnaire fit the Rasch analysis(5), person separation was 2.21, person reliability was 0.83 and the Cronbach alpha was 0.87. However, misfitted items were present. After deleting the misfitted items, the 14-item questionnaire had good validity and reliability as demonstrated by person separation and reliability (2.43, 0.86 respectively). The Cronbach alpha was 0.88. Personitem map of the 14-item showed good matching between children’s abilities and item difficulties. CONCLUSION: The 14-item of the Arabic version of IVI-C questionnaire is valid and reliable tool on school aged children with vision impairment in SA, which can be used to assess VRQOL in children with visual impairment in Arabian countries. These items include several VRQoL domains such as accessed school/ specialist instruction, social interaction, family, community and vision impairment peer interaction. Keywords: low vision, children, questionnaire, vision-related quality of life, Rasch analysis.
