Creation and investigation of the reliability and validity of the japanese version of the back beliefs questionnaire

Abstract

[Purpose] To create a Japanese version of the Back Beliefs Questionnaire (BBQ), and to investigate its reliability and validity. [Subjects] A total of 127 caregivers working at facilities who complained of back pain. [Methods] Cronbach's α coefficient for the Japanese version of the BBQ was calculated. In addition, correlations between scores on the Japanese version of the BBQ and work performance, ADL ability, and degree of back pain were investigated. [Results] The Japanese version of the BBQ had a Cronbach's alpha coefficient of 0.82. A significantly negative correlation was observed between scores on the Japanese version of the BBQ and work performance and ADL ability, but no significant correlation was observed for the degree of back pain. [Conclusions] The reliability and validity of the Japanese version of the BBQ were demonstrated. © 2012, The Society of Physical Therapy Science. All rights reserved.
