Summary
Background and Objective
Reflux Symptom Index (RSI), is a nine-item self-administered questionnaire. It is
a noninvasive tool with the purpose of assessing the symptoms of laryngopharyngeal
reflux (LPR). The purposes of the present study were to develop an Arabic version
of the RSI and to evaluate its validity, consistency, and reliability in normal Arabic
population with suspected LPR.
Setting and Design
This is a prospective study that has been carried out at Communication and Swallowing
Disorders Unit, King Saud University, Riyadh, Saudi Arabia.
Subjects and Methods
The generated Arabic RSI was administered to 52 patients with suspected LPR and to
100 control subjects. Internal consistency and test-retest reliability were evaluated.
The results of the patients and the control groups were compared.
Results
The Arabic RSI showed satisfactory internal consistency (Cronbach's α=.72). Also, good test-retest reliability was found for the total scores of the Arabic
RSI (r=0.9799, P=0.001). There was a significant difference between RSI scores of the control and the
LPR group (P<0.001).
Conclusion
This study demonstrated that Arabic RSI is a valid tool for self-assessment of LPR
that can be used by Arabic language speakers.
