摘要目的 探讨中文版合理用药自我效能量表用于评价冠心病患者服药依从性的适用性.方法 选取大连市某三甲医院循环科接受治疗的冠心病患者245例,采用中文版合理用药自我效能量表进行调查,评定该量表的信效度.结果 中文版合理用药自我效能量表具有较好的信度,其总量表的Cronbach'sα系数为0.948,2个分量表的Cronbach'sα系数为0.946、0.899,总量表的折半信度为0.954,2个分量表的折半信度为0.942、0.891,总量表的重测信度为0.928,2个分量表的重测信度为0.917、0.700;经探索性因子分析,得到2个公因子,累积贡献率为72.994%,各条目因子负荷量为0.471~0.910,均>0.4,经验证性因子分析,得到2因子模型的数据拟合度较好,经Pearson相关分析得到,量表的效标关联效度为0.881.结论 中文版合理用药自我效能量表具有较好的信、效度,适用于我国冠心病患者服药依从性的测量.

abstractsObjective To explore the applicability of Chinese version Self-efficacy for Appropriate Medication Use Scale (SEAMS) in evaluating the medication adherence of patients with coronary heart disease. Methods A total of 245 patients with coronary heart disease were selected from circulation department of a classⅢ grade A hospital in Dalian using convenience sampling method. The reliability and validity of SEAMS was evaluated in the study.Results SEAMS had a good reliability, with the Cronbach's α of 0.948. The Cronbach's α of the two branch scales were 0.946 and 0.899. The split-half reliability of SEAMS was 0.954, which the split-half reliabilities of the two branch scales were 0.942 and 0.891. The test-retest reliability of SEAMS was 0.928. The test-retest reliabilities of the two branch scales were 0.917 and 0.700. The factor analysis showed that there were two main factors with a cumulative variance rate of 72.994%. Each factor had a load capacity of 0.471-0.910, both of which were over 0.4. The confirmatory factor analysis revealed a good fit of two factors model. The Pearson correlation analysis showed that the criterion-related validity was 0.881.Conclusions The Chinses version SEAMS has a good reliability and validity, and can be used to evaluate the medication adherence of patients with coronary heart disease in our country.
