Reliability of the Arabic Glasgow benefit inventory after otolaryngology interventions

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.
