Background: A simple and self-administered ‘scratch & sniff’ test kit like the TIBSIT smell kit based on the Taiwan Smell Identification Test (TWSIT), provides a safe and quick assessment of olfaction. The original TIBSIT has been validated for use in Taiwan with age specific scores for different age groups and diagnosis. The main aim of this study is to examine if TIBSIT can be applicable for the Malaysian population and perform cultural adaptation as necessary to allow a more accurate assessment using this tool. Method and Material: A preliminary study of the original TIBSIT (Phase 1) followed by cultural adaption (Phase 2) were carried out on volunteers from various neighbourhoods in Klang Valley, Malaysia comprising of age group 16-80 years. A total of 150 test subjects and 50 test subjects were recruited for Phase 1 and Phase 2 respectively. Cultural adaptation was done with changes to the distractors that were found to be confusing. In addition, modifications included added language translation and visual reinforcement with images of the odour's substance of origin. Results: 109 out of the 150 responses were accepted for Phase 1. A detection rate of less than 75 was found in three of the odours with the remaining showing an average rate of 87.2 to 97.7. These three odours were culturally adapted for Phase 2. All 50 responses for Phase 2 were accepted; two of the odours’ detection rates improved to 98 but the plum odour was only detected 53 of the time. Conclusion: TIBSIT provides a quick office-based olfaction testing. The culturally adapted test kit is a potentially useful screening test for the Malaysian population. It is also safe and excludes the need of the clinician to carry out the test. This becomes especially useful in testing any dysosmia (hyposmia/anosmia) cases suspected of SARS-COV-2 virus infection (COVID-19). © 2021, Malaysian Medical Association. All rights reserved.
