Abstract
The aim of Tinnitus Primary Function Questionnaire is to focus on
the primary activities impaired by tinnitus so, it is more sensitive to
treatments including thoughts, emotions, hearing, sleep and
concentration. Translation of The Tinnitus Primary Function
Questionnaire into Arabic language will enrich the battery of tinnitus
analysis and improve the outcome of its management in Egypt.
In the current study, The original English version was translated into
literary Arabic after obtaining the permission of the author of the original
version by a forward- and back-translation process according to the
published guidelines for cross-cultural adaptation of health-related
quality-of-life measures. It was applied to 180 patients (100 patients
weren’t complaining of tinnitus, 80 patient with history of chronic
persistent tinnitus (more than 3 months).Validity and reliability of the
questionnaire were then assessed. Reliability includes internal
consistency reliability and test retest reliability. Validity was examined
using Mann-Whitney test and the Receiver operating characteristic
(ROC) curve. The Arabic TPFQ-12 showed high internal consistency
reliability coefficients with Cronbach’s alpha 0.819 for the study group
while control 0.806 and this is consistent with the original English TPFQ-
12 that was 0.89. Test-retest correlation was done after one weak of the
first visit for all items of the questionnaire for study and control groups.
Repeatability of the questionnaire was high for total Arabic TPFQ-12
using Spearman’s correlation (r = 0.999 and 0.998) for study and control
groups respectively. Using Mann-Whitney test there was significant
difference between the study and control groups regarding the mean of
each item and the total score of the Arabic TPFQ-12 , that was higher
