This study assessed the internal consistency reliability validity and responsiveness of the Brief Pain Inventory BPI among patients with OA undergoing total hip replacement THR . Methods We prospectively included 250 of 356 patients who were accepted to the waiting list for primary THR surgery. All participants responded to the BPI WOMAC and SF-36 at baseline and 1 year after surgery. Results Internal consistency reliability Cronbach s a was 0.80 for the BPI the WOMAC and five of the eight SF-36 scales The pattern of associations of the two BPI scales with corresponding and non-corresponding scales of the WOMAC and SF-36 largely supported the construct validity of the BPI. The responsiveness indices for change from baseline to 1 year after THR ranged from 1.52 to 2.05 for the BPI scales from 1.69 to 2.84 for the WOMAC scales and from 0.25 general health to 2.77 bodily pain for the SF-36 scales. Conclusions The BPI showed acceptable reliability construct validity and responsiveness in patients with OA undergoing THR. BPI is short and therefore is easy to use and score though the instrument offers few advantages over and duplicates scales of more comprehensive instruments such as the WOMAC and SF-36. Background Primary total hip joint replacement THR is an effective intervention for severe osteoarthritis OA of the hip that relieves the patients pain increases physical functioning and improves health related quality of life HRQoL . Previously evaluation of surgery for OA of the hip has typically been done with functional .
