抗凝治疗量表中文版效度及信度分析

目的 抗凝治疗量表（anti clot treatment scale, ACTS）是评价患者抗凝治疗满意度的有效工具，该量表分为负担和获益两个维度。本文对中文版ACTS信度及效度进行评估。方法 通过多阶段抽样法，抽取服用抗凝药物4周以上心房颤动患者，调查其ACTS评分，采用结构效度、内部信度和重测信度分别对量表的信度和效度进行评价。结果 共计1 379例患者完成量表评价，通过主成分分析提取4个因子，共同因子累计总变异解释率为67.164%；内部信度分析抗凝负担维度（13条目）及抗凝获益维度（4条目）Cronbach's α系数分别为0.823及0.968；重测信度分析提示组间相关系数在负担和获益维度分别为0.783和0.674（P<0.01）。结论 中文版ACTS具有良好效度及信度，为抗凝治疗患者自测满意度提供良好评估工具。

Validity and reliability analysis of Chinese version of Anti Clot Treatment Scale

Objective Anti Clot Treatment Scale (ACTS) is an effective tool to evaluate patients' satisfaction with anticoagulant treatment. The scale is divided into two dimensions: burden and benefit. The reliability and validity of the Chinese version of ACTS were evaluated. Methods ACTS were tested for atrial fibrillation patients that had been on oral anticoagulants (OACs) therapy for more than 4 weeks by multi stage sampling method. The reliability and validity of the scale were evaluated by structure validity, internal consistency and test retest reliability. Results ACTS data were collected in 1 379 patients. Four common factors were extracted by principal component analysis, and the total　cumulative variance contribution rate of common factors was 67.164%. Internal consistency analysis showed that Cronbach's coefficient α of ACTS Burdens scale (13 items) and Benefits scale (4 items) were 0.823 and 0.968, respectively. The test retest reliability analysis suggested that the intergroup correlation coefficients for ACTS Burdens and Benefits were 0.783 and 0.674, respectively (P<0.01). Conclusion Chinese version of ACTS has good validity and reliability, providing a scientific assessment tool for patient reported treatment satisfaction with OACs in self test.
