Background: The Fear-Avoidance Beliefs Questionnaire (FABQ) is useful for measuring fear avoidance beliefs in patients with low back pain (LBP); however, no psychometrically validated Gujarati version is available. Study Design: Cultural translation and psychometric testing. Objective: To translate and test the psychometric properties of Gujarati versions of the FABQ. Summary of Background Data: Although commonly used, no previous reports exist on the translation process or the testing of the psychometric properties of the Guajarati version of the FABQ to be used in India. Methods: Translation and cross-cultural adaptation of the original English versions of the FABQ was performed according to published guidelines. A panel of 20 healthcare professionals completed the content validity form. Test-retest reliability for the FABQ-G was examined in 30 CLBP patients. Patients completed the questionnaire twice with an interval of 48 hours. Results: The Content validity and Face validity was found to be excellent. FABQ-G exhibited excellent internal consistency shown by a Cronbachs α value of 0.843 and subscales FABQ-G-W and FABQ-G-PA also showed good internal consistencies (α=0.652 and 0.654 respectively). The test-retest reliability was excellent in chronic low back pain (CLBP) patients (ICC=0.915) and (ICC=0.864 & 0.818 for the FABQ-W and FABQ-PA, respectively). Pain intensity score had high correlation with FABQ-W (r=0.819; p
