Creation and Investigation of the Reliability and Validity of the Japanese version of the Back Beliefs Questionnaire

Abstract

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.

The Hausa Back Beliefs Questionnaire: Translation, cross-cultural adaptation and psychometric assessment in mixed urban and rural Nigerian populations with chronic low back pain

“…Thus, it can be inferred that beliefs about negative consequences of LBP may not be exclusively related to pain intensity. In line with our study, low or no correlations ( r or rho = –0.04 to –0.15) between back beliefs and pain intensity were generally reported in the literature [ 32 , 35 , 36 , 39 , 40 , 66 ].…”

“…Our alpha coefficient is slightly higher than the 0.70 reported for the original English measure [ 20 ], and the range of 0.67−0.77 reported by many language versions [ 31 , 32 , 34 , 36 , 37 , 42 , 43 ]. Other adaptations, however, reported slightly higher alpha coefficients (α range = 0.79–0.82) [ 33 , 35 , 38 , 39 , 40 ] ( Table 6 ). Though item 8 shows redundancy (weak correlation < 0.30) as also revealed by the factor analysis, deletion of this item, however, did not significantly improve the internal consistency (α = 0.75 vs .…”

“…Cronbach’s α coefficients were interpreted as “inadequate” (< 0.70), “adequate” (0.70–0.79), “good” (0.80–0.89), and “excellent” (> 0.90) [ 62 ]. We hypothesized that the Cronbach’s α coefficients for the Hausa-BBQ would lie within the range of 0.70–0.82 to be considered acceptable [ 31 , 33 , 36 , 40 , 42 ].…”

“…Furthermore, it has been shown to predict recovery rate from LBP [29]. The original English BBQ proved to be valid and reliable [20,30], and has been adapted and validated for use in several languages/cultures [31][32][33][34][35][36][37][38][39][40][41].…”
