Reliability of the Arabic Glasgow children’s benefit inventory

OBJECTIVES: To translate the Glasgow Children’s Benefit Inventory (GCBI) questionnaire into Arabic language and assess its validity and reliability in scoring the benefit of patients after cochlear implantation in children. METHODS: A cross-sectional study for a group of consecutive pediatric patients who underwent cochlear implantation between November 2018 and February 2020. The GCBI original questionnaire was translated into Arabic language and translated back to English by 2 different experts. The patients/parents were asked to complete the questionnaire given to them. RESULTS: Seventy children were included in the study. The age at implantation ranged from 7 months to 13 years with a mean of 3.4 years (SD=2.3 years). The mean GCBI score was 52.2 (SD=24.0) ranging from -6.25 to 100.00. The internal consistency of the questionnaire was high (Cronbach’s α=0.9). The 4-factor dimensions explained 55.1% of the variance. CONCLUSION: The GCBI questionnaire (Arabic version) is reliable tool to evaluate retrospectively the quality of life after an intervention in pediatric age for Arabic speaking population.
