Impairments in social and nonsocial cognition have been demonstrated in both patients suffering from bipolar disorder (BD) and their unaffected relatives and might therefore represent a heritable marker of risk. This study investigated the relevance of emotional intelligence (EI) as part of the emotion processing domain of social cognition in this regard.
A total of 54 outpatients suffering from BD, 54 unaffected siblings, and 80 control subjects were investigated using the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT) and the Brief Assessment of Cognition in Schizophrenia (BACS). Analyses of covariance (ANCOVAs) were performed with adjustment for the BACS composite score. The three groups were compared by one-way analysis of variance or chi-square test, depending on the variable type. As the three groups differed significantly in their level of education, additional ANCOVAs with adjustment for education were performed.
Patients achieved significantly lower levels of overall EI and overall nonsocial cognitive functioning compared to unaffected siblings and controls, whereas performance of the latter two groups was comparable in both domains.
Due to comparable levels of EI in unaffected siblings of patients suffering from BD and control subjects, EI assessed by means of the MSCEIT does not represent an endophenotype for BD.
社交和非社交认知方面的障碍在双相情感障碍（BD）患者及其未受影响的亲属中均有表现，因此可能代表一种可遗传的风险标志物。本研究旨在探讨情绪智力（EI）作为社会认知的情绪处理领域的一部分，在这方面的相关性。
共纳入 54 名 BD 门诊患者、54 名未受影响的兄弟姐妹和 80 名对照组参与者，采用 Mayer-Salovey-Caruso 情绪智力测验（MSCEIT）和简明精神分裂症认知评估量表（BACS）进行测试。协方差分析（ANCOVA）在调整 BACS 综合评分后进行。根据变量类型，采用单因素方差分析或卡方检验对三组进行比较。由于三组在受教育程度上存在显著差异，因此进行了额外的调整教育因素的协方差分析。
患者的总体 EI 和非社交认知功能水平明显低于未受影响的兄弟姐妹和对照组，而后两组在这两个领域的表现相当。
由于 BD 患者未受影响的兄弟姐妹和对照组的 EI 水平相当，因此 MSCEIT 评估的 EI 不能代表 BD 的内表型。
