Validity and reliability of a french version of the olfactory disorders questionnaire.

ABSTRACT:

Objective

To validate a French version of the Olfactory Disorders Questionnaire (Fr-ODQ).

Methods

Patients with olfactory disorder (OD) and controls were enrolled from two medical centers. Individuals completed the Fr-ODQ and the French version of the sinonasal outcome tool-22 (SNOT-22). The extended Sniffin'Sticks procedure was used to test odor Threshold, Discrimination, and Identification (TDI). Cronbach's alpha was used to measure the internal consistency of Fr-ODQ. The reliability and the external validity were evaluated through a test-retest approach and by correlating Fr-ODQ and SNOT-22 scores.

Results

Eighty-nine patients with OD and 65 healthy individuals completed the evaluations. The Cronbach's alpha was 0.827, reporting adequate internal consistency. The test-retest reliability was high (r_s = 0.944, p = 0.001). The external validity was adequate regarding the significant correlation between Fr-ODQ and SNOT-22 (r_s = 0.498; p = 0.001). Patients with OD reported a significant higher score of Fr-ODQ than healthy individuals (p < 0.001), indicating a high internal validity. The baseline Fr-ODQ significantly improved after 3-month olfactory training, which corroborated the improvement of TDI scores.

Conclusion

The Fr-ODQ is the first patient-reported outcome questionnaire validated for French speaking patients. Fr-ODQ is reliable and valid for the evaluation of the olfactory dysfunction and the related impact on quality of life of French-speaking patients.

Project description:Background Olfaction plays an enormous role in every aspect of life including health, emotions, social life, and safety. This is why olfactory dysfunction will leave a great impact on a person’s life. During the recent pandemic hit of coronavirus 2019 (COVID-19), much importance was given to olfaction and its sequelae post-COVID-19. There is various questionnaire being used for determining olfactory disorders worldwide. In Malaysia, Malay language is widely conversed among the local population hence an assessment tool for an olfactory specific quality of life is necessary. Method This is a cross-sectional study performed in the Otorhinolaryngology clinic in a tertiary hospital. The short Questionnaire of Olfactory Disorders-Negative Statements (sQOD-NS) is a validated questionnaire that is a simple and easy tool to assess the impact of olfactory dysfunction in daily life. The original version of the short Questionnaire of Olfactory Disorders-Negative Statements (sQOD-NS) questionnaire was translated into the Malay language. A forward-backwards translation, validity, and reliability study was done on this questionnaire. A Malay version of sQOD-NS was responded to by a total of 70 participants including 35 patients of normosia and 35 patients with smell dysfunction and repeated after 2 weeks via phone call response. The discriminant validity, internal consistency, and test re-test reliability were assessed. Results The pilot study revealed that participants who were normosmic had a higher mean score than smell dysfunction. A Student t test shows mean 20.5 ± 1.22 in normosmic group and 6.06 ± 2.41 in hyposmic group which are significant with p value of < 0.01. The coefficient of correlation (r) between test and retest scores was 0.77 (P < 0.001). Conclusion The Malay translation of sQOD-NS is a validated questionnaire that can be used both in clinical practice and in academics.

Project description:BackgroundNowadays, digital gaming occupies a central position in the entertainment industry where it has developed into a cherished kind of entertainment in markets all over the world. In addition, it provides other sectors with various social and economic benefits. The Game Experience Questionnaire (GEQ) is a free, quantitative, and comprehensive self-report measure that was developed to assess the player game experience. Despite having been widely used by many research projects in the past, it has not been adapted into Arabic. Furthermore, several components of the scale proved problematic from a psychometric point of view. Therefore, a modified version of the scale is needed to measure the gaming experience of the Arab population.ObjectiveThe aim of this study was to validate and examine the psychometrics of an adapted Arabic version of the GEQ in Tunisia.MethodsA total of 771 volunteer participants completed an online survey, which included an Arabic version of the GEQ, gaming data, and a sociodemographic questionnaire. Subjects were randomized in order to complete two phases of the study: exploratory and confirmatory. The exploratory data were acquired from 360 respondents whose mean age was 23.89 (SD 2.29) years. Out of 360 respondents, 111 (30.8%) were female and 249 (69.2%) were male. Confirmatory data were obtained from the remaining 411 subjects whose mean age was 21.94 (SD 1.80) years. Out of 411 subjects, 169 (41.1%) were female and 242 (58.9%) were male.ResultsAfter the elimination of two items, the exploratory and the confirmatory factor analyses provided an adequate factor structure of the Arabic version of the GEQ. In addition, the internal consistency coefficients suggested the reliability of the instrument. Significant differences were revealed for three subcomponents: flow by age (η2=0.013, P=.002), gender (η2=0.007, P=.02), and game type (η2=0.03, P<.001). For competence (η2=0.01, P=.03) and immersion (η2=0.02, P=.01), significant differences were highlighted by the type of game. The discriminant and convergent validities of the instrument were supported by calculating the average variance extracted (AVE) and comparing the square roots of the AVE values to the correlation coefficients, respectively.ConclusionsThe Arabic adapted version of the GEQ is valid and reliable and can be administered to measure the game experience in Arab countries.
