摘要：

目的:探讨胃肠病患者对躯体相关负性刺激的思维偏向及主观健康感受的中介作用。方法:采用16个经过标准化的模棱两可情境对30名健康人和40名胃肠病患者进行实验。结果:胃肠病患者存在明显的思维偏向。在模糊情境中,患者对负性事件发生可能性的评估显著高于健康人,而对中性事件发生可能性的评估与健康人没有差异。胃肠病患者的主观健康感受显著低于健康人。主观健康感受在健康状况与思维偏向的关系中起到完全中介作用。结论:胃肠病患者比健康人具有明显更高的思维偏向;客观健康状况并不直接导致思维偏向,而是通过主观健康感受起作用。

Objective:To explore the thinking bias towards somatic related negative stimulus and the mediating effect of perceived health in gastrointestinal disorder patients.Methods: 30 healthy participants and 40 gastrointestinal disorder patients were investigated on 16 standardized ambiguous situations.Results: Gastrointestinal disorder patients showed obvious thinking bias.In ambiguous situations, patients gave higher possibilities than healthy participants in the evaluation of negative events, while the evaluation of neutral events had no difference between the two groups.Patients had lower level of perceived health than health participants.Findings supported the complete mediating effect of perceived health on the relationship between health condition and thinking bias.Conclusion: Gastrointestinal disorder patients had high level of thinking bias toward negative information, which is not originated from the objective health condition directly, but indirectly from the patients' perceived health status.
