广泛性焦虑障碍患者的灾难化信念、绝对化信念及症状的关系探讨

The relationship between catastrophic belief,absolute belief and symptoms in patients with generalized anxiety disorder

目的:探讨广泛性焦虑障碍患者的灾难化信念、绝对化信念、无法忍受不确定性、应对方式和焦虑症状之间的相互关系。方法:采用汉密尔顿焦虑量表、灾难化信念量表、绝对化信念量表、无法忍受不确定性量表和简易应对方式问卷,对2022年3月至12月就诊于南京脑科医院医学心理科门诊的177例广泛性焦虑障碍患者进行调查,构建心理网络模型,进一步进行中介分析。结果:指向自我的绝对化在网络中的中心性最强(预期影响=1.72),其次是对他人评价的灾难化(预期影响=1.02),二者在认知层面联系最紧密(权重=0.26)。无法忍受不确定性在灾难化信念与焦虑症状中起部分中介作用,中介效应占总效应的45.80%。结论:指向自我的绝对化和对他人评价的灾难化在网络中具有核心特征,灾难化信念通过无法忍受不确定性影响个体的焦虑症状。

Objective:To explore the relationship between catastrophic belief,absolute belief,intolerance of uncertainty,coping style and anxiety symptoms in patients with generalized anxiety disorder.Method:177 patients with generalized anxiety disorder in medical psychology department of the Affiliated Brain Hospital of Nanjing Medical University from March to December 2022 were evaluated by Hamilton anxiety scale,the catastrophic belief scale,the demanding belief scale,intolerance of uncertainty scale and simplified coping style questionnaire.Psychological network model is constructed and mediation analysis is further carried out.Results:The absolutization of self-orientation has the strongest centrality in the network(expected influence=1.72),followed by the catastrotization of the evaluation of others(expected influence=1.02),and they are most closely related at the cognitive level(edge weight=0.26).Intolerance of uncertainty played a partial mediating role in catastrophic belief and anxiety symptoms,and the mediating effect accounted for 45.80%of the total effect.Conclusion:The absolutization of self-orientation and the catastrotization of the evaluation of others have core characteristics in the network,and catastrophic belief affects the anxiety symptoms of individuals through intolerance of uncertainty.
