Cardiologists are involved in the management of patients with multiple cardiovascular risk factors and chronic heart diseases, so empathy is a necessary feature to deal with them. The aim of the study was to evaluate the validity and reliability of the Spanish version of the Jefferson Scale of Physician Empathy (JSPE) among Argentine cardiologists and to explore the potential differences by age, gender, and subspecialty.
Between August and September 2012, we performed a survey in a non-randomized sample of 566 Spanish-speaking cardiologists of Argentina. A Principle Component Analysis (PCA) was used to explore the link between observed variables and latent variables in order to identify the factor structure. The PCA criteria for identifying the factor structure were examined with the Kaiser-Meyer-Olkin (KMO) analysis.
The KMO measure of sampling adequacy was 0.86 and Bartlett's test of sphericity was highly significant (p = 0.000), determining the suitability of the data set for factor analysis. The PCA of 20 items yielded a three factor model that accounted for 40.6% of the variance. The JSPE mean rank score for women was 307.9 vs. 275.0 for men (p = 0.017). The comparison of mean rank score according to age (quartiles) showed a significant relation between older age and empathy. No difference was found when the mean rank scores were compared by respondent subspecialty.
JSPE provides a valid and reliable scale to measure Argentine cardiologists' attitudes towards empathy. Female cardiologists seem to be more empathic than their male colleagues, and a positive relationship between age and empathy was found.
心脏病专家参与患有多种心血管危险因素和慢性心脏病患者的管理，因此同理心是与他们打交道的必要特征。本研究的目的是评估阿根廷心脏病专家中西班牙语版杰斐逊医生同理心量表（JSPE）的有效性和可靠性，并探讨年龄、性别和亚专业之间的潜在差异。
2012年8月至9月期间，我们对阿根廷566名讲西班牙语的心脏病专家进行了非随机抽样调查。采用主成分分析（PCA）来探索观察变量和潜在变量之间的联系，以确定因素结构。用凯泽-迈耶-奥尔金（KMO）分析来检验确定因素结构的PCA标准。
抽样适当性的KMO度量值为0.86，巴特利特球形检验高度显著（p = 0.000），确定数据集适合进行因素分析。对20个项目的主成分分析产生了一个三因素模型，该模型解释了40.6%的方差。女性的JSPE平均排名得分是307.9，而男性为275.0（p = 0.017）。根据年龄（四分位数）对平均排名得分进行比较，结果显示年龄较大与同理心之间存在显著关系。按受访者亚专业比较平均排名得分时未发现差异。
JSPE提供了一个有效且可靠的量表，用于衡量阿根廷心脏病专家对同理心的态度。女性心脏病专家似乎比男性同事更具同理心，并且发现年龄与同理心之间存在正相关关系。
