Objectives : The aims of the current study were to assess the reliability and validity of the CoRe-Ditec-BS Questionnaire-II (BSQ-II; Blood stasis questionnaire-II) with 8 items including 5 items related women added to BSQ-I that was consisted of 36 items and developed in 2013.
Methods : Between May 2014 and November 2014, 411 patients from 3 traditional Korean medical hospitals were asked to complete the BSQ-II. Each patient was independently diagnosed with BSS by two traditional Korean medical physicians from the same site. We estimated the internal consistency using Cronbach¡¯s ¥á coefficient, the discriminant validity using the means score of BSS, and the predictive validity using logistic regression (sensitivity and specificity).
Results : The BSQ-II had satisfactory internal consistency (Cronbach¡¯s ¥á coefficient=0.765) and validity, with significant differences in the mean scores between the BSS(63.60¡¾9.56) and non-BSS groups(48.36¡¾5.93). The area under the receiver operating curve was about 98%, and the sensitivity and specificity were 91.4% and 94.9%, respectively.
Conclusions : These results suggest that the CoRE-Ditec-BSQ-II is more reliable and valid instrument for estimating BSS than BSQ-I.
