We aim to translate the Glasgow benefit inventory (GBI) questionnaire into Arabic language and assess its reliability in scoring the benefit of patients after otolaryngology interventions. This is a pilot study of an ongoing prospective cohort study. The original GBI questionnaire was translated into Arabic language and back-translated into English by two different experts. The questionnaire was given to patients who were asked to fill it themselves. A group of consecutive adult patients were included in the study. Fifty-one patients were included. Reliability using Cronbach's α was higher than 0.70 for total score and the three subscales. Five loading factors explained 72.9% of the variance reached. The mean benefit of the GBI total score was 30.0 ± 36.37. Subscales scores were as follows: 35.21 ± 25.98 for the general health, 25.81 ± 45.98 for the physical benefit and 29.08 ± 34.45 for the social support. The Arabic GBI questionnaire is reliable to evaluate the quality of life after otolaryngology interventions for Arabic speaking population.

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.
