在精神分裂症谱系障碍中,共情能力缺损是一种十分普遍的社会认知障碍。近年的研究发现,述情障碍可能是这种缺损的内在机制。为了验证这一理论,本研究在811名大学生中采用《人际反映指针(IRI)量表》测量共情,采用《多伦多述情障碍量表(TAS)》测量述情障碍。分裂型特质代表非临床群体中出现的类似精神分裂症症状的行为表现,本研究中采用查普曼精神病倾向量表进行测量,包括躯体快感缺乏量表(PhAS)、社会快感缺乏量表(SAS)、知觉异常量表(PAS)及神秘观念量表(MIS)。数据分析使用网络分析方法,以IRI、TAS和查普曼精神病倾向量表的共11个分量表为节点分别构建了男性、女性和总体的偏相关网络。在一个网络中,节点之间的连接代表分量表得分之间的偏相关,节点的中心性(centrality)代表该节点在网络中的重要程度。结果显示,1)共情 -“个人痛苦”分量表与述情障碍 -“难以识别情绪”分量表存在正相关,与述情障碍-“外向性思维”分量表呈负相关;2)共情 -“共情关注”分量表与社会快感缺失呈显著负相关;共情 -“个人痛苦”分量表与躯体快感缺失呈显著负相关;3)述情障碍-“难以识别情绪”分量表的中心性最高,表明它可能是网络中最重要、与其他节点联系最紧密的变量。综上,网络分析表明共情和述情障碍、分裂型特质之间具有密切的关系,共情中的“个人痛苦”尤其受到述情障碍的影响,以上结果提示述情障碍在分裂型特质人群共情缺损中具有一定的作用,可能是精神分裂症谱系障碍人群共情缺损的内在机制和潜在的干预方向。

Other Abstract

Impaired empathy is one of the major dysfunctions commonly found in patients with schizophrenia, with alexithymia being its possible underlying cause. To test this speculation, we administered the Interpersonal Reactivity Index (IRI) to measure cognitive and affective empathy, the Toronto Alexithymia Scale (TAS) to measure alexithymia, and the Chapman scales (Chapman Scale for Social Anhedonia, CRSAS; Chapman Scale for Physical Anhedonia Scale, CPAS) to evaluate an individual’s schizotypy score. Atotal of 811 college students were queried on the IRI, TAS, and the Chapman scales. Networkanalysis method was used to explore the relationships of the above factors. In particular,regularized partial correlation (LASSO) networks of male and female participants were estimated. In the visualization of the model, items are displayed as nodes, edges represent regularized partial correlations between the nodes. Centrality denotes a node's connectedness with other nodes in the network. Negative edges were found among nodes belonging to the IRI and Chapman scale as well as among nodes belonging to TAS and IRI. Node representing the subscale TAS-F1 (“difficulty identifying feelings”) showed the highest strength centrality score. The network accuracy and stability were tested, edges and node centrality order were accurately estimated. Results show that 1) the IRI-F1(“personal distress”) is associated with TAS-F1(“difficulty identifying feelings”), while perspective taking negatively was correlated with physical anhedonia and TAS-F3 (“externally oriented thinking”); 2) the IRI-F4 (“empathic concern”) is significantly negatively correlated to social anhedonia; 3) the IRI-F1(“personal distress”) lies in the center of these relationships. These results suggest an important role of alexithymia in schizotypy individuals’ empathic deficits, especially for empathy’s sub-component “personal distress”. Overall, network analysis has highlightedthe connections between sub-components of empathy and alexithymia, implying that alexithymia may serve as a potential intervention target for the empathy deficits in schizophrenia spectrum disorders.
