A Study to Find Out Test-Retest Reliability And Validity of Gujarati Version of Quality of Life, Enjoyment, and Satisfaction Questionnaire-Short Form (Q-LES-Q-SF) Among Gujarati Speaking Indian Population

Background: The Quality-of-Life Enjoyment and Satisfaction Questionnaire-Short Form (Q-LES-Q-SF) is a widely used tool for evaluating life satisfaction across various domains. Its Gujarati version was developed to address the lack of culturally adapted tools for Gujarati-speaking populations. Method: This cross-sectional study involved the translation and validation of the Q-LES-Q-SF into Gujarati using Beaton's forward-backward translation method. Data from 300 participants aged 16–25 years were analyzed. Reliability was assessed using Cronbach's alpha and test-retest methods, while validity was determined through Pearson’s correlation with the original English version. Results: The Gujarati Q-LES-Q-SF demonstrated good internal consistency (Cronbach’s alpha = 0.802) and excellent test-retest reliability (ICC = 0.85). Concurrent validity showed a strong Pearson’s correlation (0.87, p < 0.001) between the Gujarati and English versions. Descriptive statistics revealed consistent life satisfaction scores with moderate variability. Conclusion: The Gujarati version of Q-LES-Q-SF is a reliable and valid tool for assessing quality of life and satisfaction among Gujarati-speaking individuals, making it valuable for both clinical and research applications.
