Psychometric properties of the Brazilian version of the Canine Brief Pain Inventory (CBPI) for dogs with clinical signs of osteoarthritis and preliminary evidence of its clinical utility

ABSTRACT This study aimed to determine the psychometric properties and clinical use of Brazilian version Canine Brief Pain Inventory (CBPI) in dogs with hip dysplasia (HD). Forty-three HD 16 clinically normal were enrolled. The treated daily 4.4mg/kg carprofen (GT = 21) or placebo (GP 19), for four weeks. Owners completed CBPI at two weeks (W-2) immediately before start treatment (W0), (W2) (W4) during treatment, (W6) after end treatment. internal structure was accessed, Cronbach’s alpha coefficient 0.97, indicating high consistency instrument. Principal Component Analysis (PCA) suggested retention one component, which accounted 78% variability. ROC curve analysis concluded that score 3 has an excellent performance discriminate between possible (AUC 0.973). There no difference versus placebo. instrument Portuguese showed construct criterion validity reliability be used HD.
