Brief Pain Inventory score identifying and discriminating neuropathic and nociceptive pain

WOS: 000325464200010PubMed: 23594114ObjectiveThe aim of this study was to evaluate the psychometric properties of the Brief Pain Inventory (BPI) as well as tests of its reliability, validity, and discriminative utility for estimating the status of chronic pain in neuropathic and nociceptive pain patients. Method and patientsWe enrolled 224 chronic pain (126 neuropathic pain and 98 nociceptive pain) patients. The original version of the BPI was translated into Turkish by standard procedures. An independent clinician determined the pain type. The factor analysis, reliability (internal consistency and test-retest reliability), and validity (agreement with the reference diagnosis and sensitivity, specificity, and positive and negative predictive values) were determined. Discriminant function analysis was then employed to determine whether BPI could differentiate between neuropathic and nociceptive pain. ResultsCronbach's -coefficient was 0.84 for the test and 0.83 for the retest. BPI scores for subjects did not significantly differ between applications r:0.96 (P
