Background: The chronic rhinosinusitis patient-reported outcome (CRS-PRO) is a recently published disease-specific questionnaire designed for CRS patients, with fewer entries and ease of completion. This study aimed to translate the CRS-PRO questionnaire into Chinese and assess its reliability, validity, and responsiveness to provide Chinese patients with a more concise and efficient subjective assessment instrument. Methods: The Chinese version of the CRS-PRO was created through forwardbackward translations and cultural adaptation. Here, 168 CRS patients (118 patients CRS with nasal polyps [CRSwNP] and 50 patients with CRS without nasal polyps [CRSsNP]) and 43 healthy individuals were enrolled. All participants completed the CRS-PRO, 22-item Sinonasal Outcome Test (SNOT-22), and EuroQol five dimensions questionnaire (EQ-5D) questionnaires preoperatively as well as 3 and 6 months after surgery. Results: The Chinese version of the CRS-PRO demonstrated good internal consistency, with a Cronbach's a of 0.813. It also exhibited a higher criterion validity (r=0.65, p<0.05) than the SNOT-22.Amoderate associationwas found between the CRS-PRO and objective indicators such as the Lund-Mackay and endoscopic scores. Furthermore, the CRS-PRO, like the SNOT-22, could clearly distinguish CRS patients from healthy subjects (p < 0.01), as well as between the CRSwNP and CRSsNP subtypes (p < 0.01). Additionally, changes in the CRS-PRO exhibited a larger effect size compared to changes in the SNOT-22 (Cohen's d = 1.05 and 0.93 vs. 0.71 and 0.90 for 3 and 6 months, respectively, all p < 0.01). Conclusions: The Chinese version of the CRS-PRO is a concise, reliable, and responsive instrument that can be utilized as a novel subjective evaluation tool for future clinical practice.
