Validation of the Electronic Form of the Persian Version of Health-related Quality of Life Questionnaire for Iranian Patients With COVID-19

Background and Objectives: Validation of the tools used for assessing the quality of life (QoL) can help address the problems of patients with COVID-19 in Iran. Therefore, this study aims to validate the electronic form of the Persian version of health-related quality of life (HRQoL) questionnaire for Iranian patients with COVID-19. Methods: This is a psychometric study. The study population included all patients with COVID-19 in Tehran, Iran. Samples were selected by a cluster sampling method. In this regard, 100 patients were selected for determining the criterion validity and 330 were selected for assessing the convergence validity. The research data were collected electronically by using Hlubocky et al.’s HRQoL questionnaire and the World Health Organization quality of life-BREEF (WHOQoL-BREF) questionnaire. Content validity, convergence validity, and factor analysis methods were used to evaluate the psychometric properties of the Persian HRQoL. The reliability was assessed by internal consistency and split-half methods. Results: The results of exploratory factor analysis showed that the questionnaire had two factors. It had also good validity and reliability. The second-order confirmatory factor analysis confirmed its two-factor structure. Its score had good relationship with the score of WHOQoOL-BREF. Conclusion: The electronic form of the Persian HRQoL can be used to assess the QoL of patients with COVID-19 in Iran.
