Intrinsic consistency and retest confidence table in the Chinese version of Brief Pain Inventory （BPI-C） in cancer patients

Objetive To study the intrinsic consistency and retest confidence in the Chinese version of Brief Pain Inventory（BPI-C） in cancer patients. Methods Fifty cancer patients were enrolled in this study. The intrinsic consistency and retest confidence were tested in cancer patients using the BPI-C by experienced nurses independently in the morning and afternoon. Results The Cronbach alpha coefficient of BPI-C was 0.954 and 0.958, respectively. The Cronbach’s alpha and intra-class correlation（ICC） coefficients of 12 items in the BPI-C were 0.947-0.961 and 0.774-0.89, respectively. Conclusion The intrinsic consistency and retest confidence in BPI-C are rather good in cancer patients. The results of this study may provide reference for the use of BPI-C.
