目标:负面影响,述情障碍,和其他易感特征(如健康焦虑)可以影响个体的症状感知。在这项研究中,我们使用了情感图片范式(APP,Bogaerts等人。,2010)使用情感图片刺激诱发症状。我们旨在横截面测试高频和低频症状查询的效果,并分析APP的时间过程,包括与健康焦虑和躯体症状困扰的相互作用。
方法:参与者(N=124)完成了修改后的APP并填写了各种问卷。在APP中,参与者被随机分配到高频查询条件(18项症状检查表)或低频查询条件(6项检查表).数据采用方差分析,交叉滞后面板模型,适度模型,和多层次模型。
结果:两组症状基线值相当,但是,一旦实验开始,与频率较低的人相比,频率较高的人报告的症状水平显着升高(F(1,120)=14.319,p<.001,η2=.107)。症状水平在实验过程中保持稳定,并且通过在实验中的较早时间点的症状水平最好地预测(β=0.43和β=0.68,均p<.001)。健康焦虑水平显着预测症状水平(F(1,121)=10.054,p=.002,η2=.077),并缓和了病情和症状水平之间的关系(F(2,121)=16.253,p<.001,η2=.212)。
结论:就预测处理模型而言(例如,[1]),负面情感线索后的重复症状查询可能会激活先前对症状的信念,导致与健康焦虑相互作用的症状报告水平升高。
OBJECTIVE: Negative
affect, alexithymia, and other predisposing traits (such as health anxiety) can influence an individual\'s symptom perception. In this study, we used the affective picture paradigm (APP, Bogaerts et al., 2010) to induce symptoms using affective picture stimuli. We aimed to cross-sectionally test the effect of high vs low-frequency symptom queries and analyze the time course of the APP, including interactions with health anxiety and somatic symptom distress.
METHODS: Participants (N = 124) completed a modified APP and filled out various questionnaires. In the APP, participants were randomized to either a highly-frequent-query condition (18 symptom checklists) or a less-frequent-query condition (6 checklists). Data were analyzed using ANOVAs, cross-lagged panel models, moderation models, and multilevel models.
RESULTS: Both groups had comparable symptom baseline values, but people in the highly frequent as opposed to less frequent condition reported significantly higher symptom levels once the experiment started (F (1,120) = 14.319, p < .001, η2=.107). Symptom levels stayed stable over the course of the experiment and were best predicted by symptom levels at earlier timepoints in the experiment (β = 0.43 and β = 0.68, both p < .001). Health anxiety levels significantly predicted symptom levels (F(1,121) = 10.054, p = .002, η2=.077) and moderated the relation between condition and symptom levels (F(2,121) = 16.253, p < .001, η2=.212).
CONCLUSIONS: In terms of the predictive processing model (e.g.,[1]), repeated symptom queries following negative affective cues may activate prior beliefs about symptoms, resulting in elevated levels of symptom
reports in interaction with health anxiety.
