目的：研制一种可重复使用的、有效的视觉模拟评分(VAS)问卷，用于评估狗的疼痛和跛行。样本群体-48只轻到中度跛行的客户拥有的狗。在48只狗中，19只用于重复性评估，48只用于主成分分析，44只用于模型选择和有效性检验。在狗身上进行了重复性的测试，垂直峰力变化了10%。使用测力台作为检测跛行的标准参考标准。主成分分析用于描述数据的维度。在多元回归模型中，可重复问题被用作解释变量来预测测力板测量值。垂直峰值、头尾骨和相关的冲动是用来量化跛行的力量。结果在39个问题中，有19个问题是可重复的，以Spearman等级相关分界点为>；0.6。模型选择程序产生了三个重叠的问题子集，这些问题被认为是测量的力(垂直峰值、垂直冲量和推进峰值)的有效表示。每个简化的模型都符合数据和完整模型。结论和临床相关性-VAS问卷可重复使用，可用于评估狗的轻到中度跛行程度。
Objective-To develop a visual analogue scale (VAS) questionnaire that is repeatable and valid for use in assessing pain and lameness in dogs.Sample Population-48 client-owned dogs with mild to moderate lameness.Procedure-The dogs were from 3 studies conducted during a 3-year period. Of the 48 dogs, 19 were used in repeatability assessment, 48 were used in principal component analysis, and 44 were used in model selection procedures and validity testing. A test-retest measure of repeatability was conducted on dogs with a change of < 10% in vertical peak force. A force platform was used as the criterion-referenced standard for detecting lameness. Principal component analysis was used to describe dimensionality of the data. Repeatable questions were used as explanatory variables in multiple regression models to predict force plate measurements. Peak vertical, craniocaudal, and associated impulses were the forces used to quantify lameness. The regression models were used to test the criterion validity of the questionnaire.Results-19 of 39 questions were found to be repeatable on the basis of a Spearman rank-correlation cut point of > 0.6. Model selection procedures resulted in 3 overlapping subsets of questions that were considered valid representations of the forces measured (vertical peak, vertical impulse, and propulsion peak). Each reduced model fit the data as well as the full model.Conclusions and Clinical Relevance-The VAS questionnaire was repeatable and valid for use in assessing the degree of mild to moderate lameness in dogs.
