The purpose of this study was to test the reliability and validity of the Korean version of the fear of daily activities questionnaire (FDAQ) for low back pain patients. Seventy-three subjects with low back pain were participated in this study. The subjects completed ten standardized self-administered questionnaires that measure fear of specific daily activities. The reliability of the acquired data was determined by the intra-class correlation coefficient (ICC) and the Cronbach's ${\alpha}$ for internal consistency. Constructive validity was analyzed by factor analysis, and concurrent validity was acquired from comparison FDAQ scores to the visual analogue scale (VAS) and Oswestry disability index (ODI) scores. The test-retest reliability of the Korean version of the FDAQ showed good ICC (2,1)= 0.96 (95%CI and Cronbach's alpha value was 0.93. Factor analysis suggested two factors solution consisting of spinal loading and spinal movement/posture, it explained 76.1% of the total variance. The concurrent validity was moderately related with pain and disability. Therefore, the Korean version of the FDAQ is a useful method for measuring the fear of daily activities of patients with low back pain.
