Objective This study aims modify the SFAR tropical climate, translate modified from English Malay Language, and validate this Malaysian version of (MySFAR). Methods cross-sectional at an outpatient Otorhinolaryngology clinic tertiary center. There were 2 phases study: (1) translation validation (2) testing diagnostic accuracy. Two different groups participants recruited respective phase. Results In phase 1, total MySFAR score showed good discriminant validity between AR healthy controls (13.44 ± 1.58 v 1.00 2.12, p < 0.01). The internal consistency test–retest reliability excellent with Cronbach’s alpha 0.92 (95% CI 0.90–0.94) intraclass correlation coefficient 0.97, 0.01. 2, gave AUC 0.98 = 0.96–1.00, 0.01), cut-off > 9 ( J 0.92) determined based on highest Youden index. 97.8% sensitive 93.9% specific predicting non-allergic rhinitis. Conclusion present among population. able predict would be useful screening tool studies countries.
