Abstract
Background: Rhinosinusitis is an inflammatory disease of the nose and paranasal sinus that disrupts personal, professional, and social life. The Rhino Quality of Life (RhinoQOL) questionnaire is a short and self-administered questionnaire for assessing the symptoms and quality of life of patients with chronic rhinosinusitis (CRS). Methods: This cross-sectional study is conducted at the otorhinolaryngology (ORL) clinic in the Hospital Raja Perempuan Zainab II and Hospital Universiti Sains Malaysia. The forward and backward translation of the RhinoQOL questionnaire into the Malay language was performed and tested for content and face validity. The comparison between patient and control groups were evaluated using the independent t-test and Pearson chi-square. The psychometric properties (validity, reliability, reproducibility, and responsiveness) were assessed. Results: We observed 114 patients (64 patients and 50 controls). The mean age was 46 years old, and 65% were male patients. CRS patients with nasal polyp account for 76.7%. The Pearson's correlation demonstrated that all the symptom scales correlate and measure the same things. The Cronbach's α coefficient value for each symptom scale was acceptable, within 0.6-0.9. Test-retest evaluation was good, with the value of intraclass correlation (ICC) more than 0.70. After the surgery, there was a significant improvement from baseline for all sub-scale scores, indicating clinical improvement. Conclusions: The Malay version of the RhinoQOL is equivalent to the original English version. It is an effective tool to assess the CRS patients' symptoms and quality of life based on the validity, reliability, reproducibility, and responsiveness values obtained. Therefore, its use is recommended in daily practice.
