The aim of this study was to perform the initial psychometric evaluation of the Portuguese version of the Canine Orthopaedic Index (COI).
In a prospective, randomized study, a group of 50 police working dogs with bilateral hip osteoarthritis was assessed. A copy of the translated Portuguese version of the COI was completed by canine handlers, native Portuguese speakers. This result was compared with that of 50 sound dogs. Construct validity was determined by comparing sound dogs and dogs with osteoarthritis scores with the Mann-Whitney test. Additionally, the Kaiser-Meyer-Olin measure of sampling adequacy, eigenvalue, and scree-plot analysis were performed. Internal consistency was tested with Cronbach's α.
A significant difference was observed between osteoarthritis and sound dogs in all dimensions of the COI ( < 0.01 for all), indicating construct validity. Two factors accounted for 87.8% of the total variance. Cronbach's α was 0.98, with a high interitem correlation, accounting for strong internal consistency.
We presented criterion and construct validity of the Portuguese version of the COI. It is a step in providing clinicians with a validated and accessible tool to evaluate orthopaedic patients. Further studies are required.
本研究旨在对犬科骨科指数（COI）的葡萄牙语版本进行初步心理计量学评估。
在一项前瞻性、随机研究中，对 50 只双侧髋关节骨关节炎的警犬进行了评估。犬类饲养员（以葡萄牙语为母语的人）填写了经过翻译的 COI 葡萄牙语版本副本。将这一结果与 50 只健康犬进行了比较。通过曼-惠特尼检验比较健康犬和骨关节炎犬的得分，以确定结构效度。此外，还进行了 Kaiser-Meyer-Olin 采样充分性度量、特征值和碎石图分析。采用 Cronbach's α 检验内部一致性。
COI 的所有维度在骨关节炎犬和健康犬之间均存在显著差异（所有维度均为 < 0.01），表明具有结构效度。两个因素占总方差的 87.8%。Cronbach's α 为 0.98，各项目间相关性高，表明具有较强的内部一致性。
我们提出了 COI 葡萄牙语版本的标准和结构效度。这是为临床医生提供一种经过验证且易于使用的工具来评估骨科患者的重要一步。还需要进一步的研究。
