The reliability and validity of the Korean version of the Japanese orthopaedic association back pain evaluation questionnaire.

[Purpose] The purpose of this study was to establish the reliability and validity of the Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ) translated into Korean for use with patients' low back pain. [Subjects and Methods] Sixty-two subjects with low back pain, 28 men and 34 women, participated in the study. Reliability was determined by using the intra class correlation coefficient and Cronbach's alpha for internal consistency. Validity was examined by correlating the JOABPEQ scores with the 36 item short form health survey (SF 36). [Results] Test-retest reliability was 0.75-0.83. The criterion-related validity was established by comparison with the Korean version of the SF 36. [Conclusion] The Korean version of the JOABPEQ was shown to be a reliable and valid instrument for assessing low back pain.
