为了改进和测试用于评估接受卵巢子宫切除术的猫的急性术后疼痛的复合疼痛量表的结构效度和可靠性，样本人群-在先前的研究中接受卵巢子宫切除术的40只猫。程序-在先前的随机、双盲、安慰剂对照研究中，开发了复合疼痛量表以评估接受安慰剂或止痛剂的猫的术后疼痛。（曲马多、维达洛芬或曲马多-维达洛芬组合）。在本研究中，该量表通过项目分析（分布频率和发生率），非参数方差分析和项目与总分的相关性进行了改进。结构效度通过因素分析和已知组的歧视，和信度进行了评估，通过评估内部consistency.Results-Respiratory率和呼吸模式项目分析后被拒绝。因子分析得到5个维度（F1 [心理变化]，姿势，舒适度，活动，精神状态和其他行为; F2 [伤口区域保护]，对手术伤口触诊和腹部和侧腹触诊的反应; F3 [生理变量]，收缩期动脉血压和食欲; F4 [疼痛的声音表达]，发声;和F5 [心率]）。整体量表以及F2和F3的内部一致性非常好; F4非常好; F5不可接受。除了心率，确定的因素和规模总得分可以用来检测镇痛剂和安慰剂组之间的差异和镇痛treatment.Conclusions和临床相关性，结果之间的差异提供了初步证据的多维复合工具，用于评估急性术后疼痛猫卵巢子宫切除术的结构效度和可靠性。(Am J Vet Res 2011;72：174-183）
Objective-To refine and test construct validity and reliability of a composite pain scale for use in assessing acute postoperative pain in cats undergoing ovariohysterectomy.Sample Population-40 cats that underwent ovariohysterectomy in a previous study.Procedures-In a previous randomized, double-blind, placebo-controlled study, a composite pain scale was developed to assess postoperative pain in cats that received a placebo or an analgesic (tramadol, vedaprofen, or tramadol-vedaprofen combination). In the present study, the scale was refined via item analysis (distribution frequency and occurrence), a nonparametric ANOVA, and item-to-total score correlation. Construct validity was assessed via factor analysis and known-groups discrimination, and reliability was measured by assessing internal consistency.Results-Respiratory rate and respiratory pattern were rejected after item analysis. Factor analysis resulted in 5 dimensions (F1 [psychomotor change], posture, comfort, activity, mental status, and miscellaneous behaviors; F2 [protection of wound area], reaction to palpation of the surgical wound and palpation of the abdomen and flank; F3 [physiologic variables], systolic arterial blood pressure and appetite; F4 [vocal expression of pain], vocalization; and F5 [heart rate]). Internal consistency was excellent for the overall scale and for, F2, and F3; very good for F4; and unacceptable for F5. Except for heart rate, the identified factors and scale total score could be used to detect differences between the analgesic and placebo groups and differences among the analgesic treatments.Conclusions and Clinical Relevance-Results provided initial evidence of construct validity and reliability of a multidimensional composite tool for use in assessing acute postoperative pain in cats undergoing ovariohysterectomy.
