Abstract
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.
