Validation of an Arabic Version of the Obesity-Related Wellbeing (ORWELL 97) Questionnaire in Adults with Obesity

摘要

Background: No specific questionnaire that evaluates Health-Related Quality Of Life(HRQOL) in individuals with obesity is available in the Arabic language. The aim of this study wastherefore to propose and examine the validity and reliability of an Arabic language version of theORWELL 97, a validated obesity-related HRQOL questionnaire.Methods: The ORWELL 97 questionnaire was translated from English to Arabic language and administeredto 318 Arabic-speaking participants (106 from clinical and 212 from community samples), andunderwent internal consistency, test–retest reliability, construct and discriminative validity analysis.Results: Internal consistency and the test–retest reliability were excellent for ORWELL 97 globalscores in the clinical sample. Participants with obesity displayed significantly higher ORWELL 97scores than participants from the community sample, confirming the good discriminant validity of thequestionnaire. Confirmatory factor analysis in the clinical sample revealed a good fit for a modifiedtwo-factor structure.Conclusion: Overall, the Arabic version of the ORWELL 97 can be considered validated in Arabicadult patients with obesity, paving the way to further assessment of its responsiveness in measuringchanges in health-related quality of life associated with obesity treatment.
