Pain assessment is of paramount importance for properly managing dogs with osteoarthritis (OA) pain. The aim of the present study was to develop and psychometrically validate the Italian version of the Helsinki Chronic Pain Index (I-HCPI). Owners of OA painful ( = 87) and healthy dogs ( = 40) were administered the I-HCPI once or twice after an eight-week meloxicam treatment. Sixty-nine owners of healthy and OA dogs also completed the Italian version of the Canine Brief Pain Inventory (I-CBPI). Pain on palpation on a 0-4 scale was assessed on all recruited dogs. Construct validity was tested both with hypothesis testing and principal component analysis, confirming the I-HCPI accurately measured chronic pain. Good convergent and criterion validity were shown through correlations with I-CBPI subscores and distribution among pain on palpation scores ( < 0.0001). The significant difference between the pre- and post-treatment I-HCPI scores ( < 0.0001) and Cohen's effect size (2.27) indicated excellent responsiveness. The I-HCPI was shown to be reliable through communalities (range 0.47-0.90) and Cronbach α (≥0.95). Discriminative ability and cut-off point, as tested through Receiver Operating Characteristic analysis, showed excellent diagnostic accuracy with a threshold value of 11 (specificity 0.98 and sensitivity 0.94). The I-HCPI was confirmed to be a valid, sensitive, reliable, and accurate tool to discriminate between dogs with and without pain.
疼痛评估对于妥善管理患骨关节炎（OA）疼痛的犬只至关重要。本研究的目的是开发并进行心理测量学验证赫尔辛基慢性疼痛指数意大利语版（I-HCPI）。OA疼痛犬（n = 87）和健康犬（n = 40）的主人在接受为期八周的美洛昔康治疗后接受一次或两次I-HCPI测试。69名健康犬和OA犬的主人还完成了犬简短疼痛量表意大利语版（I-CBPI）。对所有招募的犬只进行0-4级触诊疼痛评估。通过假设检验和主成分分析对结构效度进行测试，证实I-HCPI能够准确测量慢性疼痛。通过与I-CBPI子分数的相关性以及触诊疼痛评分的分布（P < 0.0001）显示出良好的收敛效度和效标效度。治疗前和治疗后I-HCPI分数之间的显著差异（P < 0.0001）以及科恩效应量（2.27）表明具有出色的反应性。通过共同度（范围0.47 - 0.90）和克朗巴哈α系数（≥0.95）表明I-HCPI具有可靠性。通过接受者操作特征分析测试的判别能力和临界点显示，阈值为11时具有出色的诊断准确性（特异性0.98，敏感性0.94）。I-HCPI被证实是区分疼痛犬和非疼痛犬的有效、敏感、可靠且准确的工具。
