ABSTRACT
ABSTRACT
Exercise adherence is essential for achieving optimal rehabilitation outcomes; however, adherence to prescribed home exercise programs is often low. Accurate assessment requires reliable and culturally appropriate tools. The Exercise Adherence Rating Scale (EARS) is a validated self-reported measure of exercise adherence, but no Gujarati version is currently available. Therefore, this study aimed to translate, culturally adapt, and evaluate the reliability and validity of the Gujarati version of EARS (G-EARS).
Methods: This methodological study followed Beaton’s guidelines for cross-cultural adaptation, including forward translation, synthesis, back translation, and expert committee review. For psychometric evaluation, 42 participants (mean age: 43.47 ± 8.84 years) with Type 2 Diabetes Mellitus (T2DM), back pain, and early osteoarthritis were recruited. Content validity was assessed using Content Validity Ratio (CVR), Item-Level Content Validity Index (I-CVI), and modified kappa statistics. Reliability was evaluated using test–retest reliability (Intraclass Correlation Coefficient, ICC) and internal consistency (Cronbach’s alpha).
Results: All items demonstrated excellent content validity (CVR = 1; I-CVI > 0.79; k = 1). The G-EARS showed excellent test–retest reliability (ICC = 0.87) and high internal consistency (Cronbach’s alpha = 0.93), indicating strong reliability.
Conclusion: The Gujarati version of EARS (G-EARS) is a reliable and valid tool for assessing adherence to prescribed home exercise programs and can be effectively used in clinical and research settings among Gujarati-speaking populations.
