ABSTRACT
Introduction: Fatigue is defined as a condition of unusual tiredness, weakness, and exhaustion and significantly lowers patients' quality of life. Being a subjective scale, FAS must be available in different languages to record the fatigue level.
Aims: The aim is to translate the FAS in Gujarati language and to test its validity and reliability in normal population.
Methods and Material: This is a cross-sectional study which was conducted in Ahmedabad, Gujarat from July 2022 to September 2022 with the permission from original author. The study was conducted in 3 steps that is translation, face and content validity and test-retest reliability. Beaton’s guidelines were followed for the process of translation. Total 10 experts were taken for the process.
Result: Mean age of 34.89 ± 17.81years, total 120 participants were included. Statistically, CVR ratio for item 4 and 10 was 0.8 and 1 for all other items of the scale. The I-CVI value for item 4 and 10 was 0.9 and 1 for all other items. The α value was 0.91 and Correlation Coefficient value was 0.92 showed that the Gujarati FAS has excellent test-retest reliability. For content validity, the kappa value of k=0.75 (95%CI: 0.749, 0.755, p = 0.000), which indicates substantial agreement between the raters.
Conclusion: The Gujarati FAS scale is a brief, easy-to-use, reliable, and valid scale for assessing fatigue in healthy Gujarati population.
