社区慢性病共病老年人述情障碍与认知情绪调节策略关系的网络分析

Network analysis of association between alexithymia and cognitive-emotional regulation strategies in older adults with chronic co-morbidities in communities

目的:探讨社区慢性病共病老年人述情障碍与认知情绪调节策略网络中的核心节点和桥梁节点。方法:选取社区慢性病共病老年人436名,采用多伦多述情障碍量表(TAS)和认知情绪调节问卷(CERQ)进行调查。基于R语言进行网络估计、中心性及可预测性测量、准确性及稳定性验证和网络比较,以识别网络中的核心节点和桥梁节点,比较不同性别和居住地的网络结构差异。结果:CERQ灾难化维度是网络中强度最高的节点(strength=1.28),被确定为核心节点。TAS情感识别障碍维度(bridge strength=0.52)的桥梁强度最高,然后是TAS外向型思维维度(bridge strength=0.48)、CERQ自我责难维度(bridge strength=0.41),被确定为桥梁节点。网络比较测试结果显示,不同性别及居住地的慢性病共病老年人述情障碍与认知情绪调节策略网络结构差异无统计学意义(P>0.05),但网络内各节点均紧密连接。结论:慢性病共病老年人以灾难化作为主要的认知情绪调节策略,情感识别障碍、外向型思维和自我责难是其述情障碍与认知情绪调节策略连接的主要途径。

Objective:To explore core and bridge nodes in a network of alexithymia and cognitive emotion regulation strategies in older adults with chronic co-morbidities in the communities.Methods:Totally 436 older a dults with chronic co-morbidities in the communities were selected and surveyed with the Toronto alexithymia Scale(TAS)and Cognitive Emotion Regulation Questionnaire(CERQ).Network estimation,centrality and predictability measurements,accuracy and stability validation,and network comparisons based on the R language were performed to identify core and bridge nodes in the network and to compare differences in net work structure across gender and residence.Results:Catastrophizing was the highest strength node in the network(strength=1.28)and was identi-fied as a core node.The difficulty identifying feelings had the highest bridge strength(bridge strength=0.52),fol-lowed by the externally oriented thoughts(bridge strength=0.48),and blaming oneself(bridge strength=0.41)were identified as bridge nodes.The results of the network comparison test showed that the differences in the struc-ture of the network of alexithymia and cognitive emotion regulation strategies among older adults with chronic co-morbidities across gender and place of residence were not statistically significant(P>0.05),but the nodes within the network were tightly connected.Conclusion:Older adults with chronic co-morbidities use catastrophizing as a primary cognitive-emotional regulation strategy.Difficulty identifying feelings,externally oriented thoughts and self-blame as the main ways in which their alexithymia are connected to cognitive-emotional regu lation strategies.
