Objective: To develop a French Short Version of the Questionnaire of Olfactory Disorders-Negative Statements (Fr-sQOD) to assess the quality of life impairments of patients with olfactory dysfunction (OD). Methods: Patients with OD and controls were enrolled from 2 academic centers. Individuals completed the Fr-sQOD, an OD visual analog scale severity, and the French version of the sinonasal outcome tool-22 (SNOT-22). Cronbach α was used to measure the internal consistency of Fr-sQOD. The reliability and the external validity of Fr-sQOD were assessed through a test–retest approach and by correlating Fr-sQOD with SNOT-22 scores, respectively. The external validity was assessed by correlation analysis between Fr-sQOD and the result of an assessment of the severity of OD on a visual analog scale. Results: Eighty patients completed the evaluations. The internal consistency was adequate (Cronbach α.96), and the test–retest reliability was high in the entire cohort (r
s = 0.877, P <.001). The correlation between Fr-sQOD total scores and the severity of OD was moderate but significant (rs = −0.431; P =.001) supporting an acceptable external validity. Patients with OD had a significantly higher score of Fr-sQOD than healthy individuals (P <.001), indicating a high internal validity. Conclusion: The Fr-sQOD is a reliable and valid self-administered tool in the evaluation of the impact of OD on quality of life of French-speaking patients. [ABSTRACT FROM AUTHOR]- Published
