Objectives: To translate, culturally adapt, and validate the Self-Reported Mini Olfactory Questionnaire (Self-MOQ) for use in the Portuguese population.
Materials and Methods: The translation process adhered to internationally recognized guidelines. Validation was performed with 50 participants: a test group of 25 individuals reporting olfactory complaints with confirmed olfactory dysfunction according to the Portuguese Smell Test, and a control group of 25 participants without olfactory complaints. All participants completed the questionnaire twice, with an average interval of three weeks. Statistical analyses were conducted using SPSS.
Results: The Portuguese version of the Self-MOQ demonstrated excellent internal consistency (Cronbach’s α = 0.937) and outstanding test–retest reliability (mean intraclass correlation coefficient = 0.98). Discriminant validity was supported by a statistically significant difference in questionnaire scores between the test and control groups.
Conclusions: The Portuguese version of the Self-MOQ is a reliable and valid instrument for screening olfactory dysfunction.
