“…The internal consistency value of the Fr-sQOD-NS is comparable to the value of the original paper of Simopoulos et al who reported a Cronbach a of .88. 4 In the Spanish version of sQOD-NS, Chiesa-Estomba et al 14 found a Cronbach a of .861, which was also comparable to ours. 6 In the same vein, the test-retest reliability of Fr-sQOD-NS, also named external reliability, was high for total scores (r s ¼ 0.877, P < .001) and moderate-to-high for item scores.…”

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 (rs = 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.

“…No other translation of this specific questionnaire is available in the literature, but our results for the QOD-NS subscale can be compared to those from Mattos' QOD-NS 10 and its adaptations. In fact, the French translation of QOD-NS (Fr-sQOD-NS) 2,3 had α = 0.96, while the internal consistency of Chiesa-Estomba's Spanish version 22 measured with Cronbach α was 0.86. As far as the reliability of the Brief-IT-QOD is concerned, the scores obtained in the test-retest analysis support the hypothesis that Brief-IT-QOD has high stability and reproducibility over time.…”

Objective. To evaluate the reliability and validity of the Italian version of the Brief Questionnaire of Olfactory Disorders (Brief-IT-QOD). Methods. The study consisted of six phases: item generation, reliability analysis (112 dysosmic patients for internal consistency analysis and 61 for test-retest reliability analysis), normative data generation (303 normosmic subjects), validity analysis (comparison of Brief-IT-QOD scores of healthy and dysosmic subjects and scores correlation with psychophysical olfactory testing TDI and SNOT-22 scores), responsiveness analysis (10 dysosmic chronic rhinosinusitis with nasal polyps patients before and after biologic therapy), and cutoff value determination (ROC curve analysis of Brief-IT-QOD sensitivity and specificity). Results. All subjects completed the Brief-IT-QOD. Internal consistency (α > 0.70) and test-retest reliability (ICC > 0.7) were acceptable and satisfactory for both questionnaire subscales. A significant difference between dysosmic and control subjects was found in both subscales (p < 0.05). Significant correlations between subscales scores and TDI and SNOT-22 scores were observed. Brief-IT-QOD scores before treatment were significantly higher than after biological therapy. Conclusions. Brief-IT-QOD is reliable, valid, responsive to changes in QoL, and recommended for clinical practice and outcome research.

“…27 The shorter version was developed to increase the response rate and reduce the patient's mental processing when answering the questionnaire. It was translated in Spanish 28 and Italian 6 and was used to investigate impact of olfactory dysfunction on quality of life among COVID-19 patients. 29 The short version was used due to good reliability, ease of answering which requires a short amount of time, and relevance of the 4 subdomains covered.…”

ABSTRACTObjective: To determine the quality of life among SARS-CoV-2 (COVID-19) positive patients with anosmia using the Short Version Questionnaire of Olfactory Disorders - Negative Statements translated in Filipino (sQOD-NS Ph). Methods: Design: Cross-Sectional Study Setting: Tertiary Government Training Hospital Participants: SARS-CoV-2 (COVID-19) RT-PCR positive patients aged 18 years old and above with COVID-19 symptoms and anosmia in a tertiary government hospital who consulted from March 2020 to August 2021 answered the short version of sQOD-NS Ph. Results: Out of 108 participants with positive SARS-CoV-2 (COVID-19) RT-PCR test, 72 (66%) presented with anosmia, and sQOD-NS Ph scores ranged from 1 to 21 with a mean of 14.78. Thirty two (44%) encountered problems in eating while 21 (29%) had feelings of isolation due to loss of smell. There was an inverse correlation of -0.478 between recovery time of olfaction and QoL score, hence the longer the recovery time, the lower the QoL score, while the shorter the recovery time, the higher the QoL score (p < .0001). Conclusion: Majority of COVID-19 patients with anosmia had mild or negligible impairment, while a small percentage had impaired quality of life. The low percentage may be due to high number of patients who may have recovered their sense of smell along the course of the disease.
