中文摘要：

目的考察不同反刍性沉思类型的意外创伤者的注意偏向特点。方法采用中文版反刍性沉思问卷,筛选目的性反刍性沉思、侵入性反刍性沉思的被试创伤者各30名,以正性、负性、中性情绪图片为试验材料进行点探测试验。结果目的性反刍性沉思伤者存在对正性情绪图片的注意偏向,其正性情绪图片的注意偏向及指向指数均显著大于0（P〈0.05）;侵入性反刍性沉思伤者存在对负性情绪图片的注意偏向及注意脱离困难,其负性情绪图片的注意偏向及注意脱离指数均显著大于0（P〈0.05）。结论不同反刍性沉思类型伤者的注意偏向特点或可为临床开展意外创伤者创伤后认知应对的心理干预提供依据。

Objective To explore the characteristics of attentional bias in accidentally injured patients with different types of rumination.Methods Chinese version of event-related rumination inventory was adopted to screen out 30 deliberate rumination group and intrusive rumination group respectively among accidentally inj ured patients.Dot probe task was used with positive,negative and neutral facial expression pictures as experimental materials.Results Patients with deliberate rumination had attentional bias and attentional orienting towards the positive emotional stimuli.The value of attentional bias and orienting index were both significantly higher than 0（P〈0.05）.Patients with intrusive rumination had attentional bias towards the negative emotional stimuli,and difficulty in distraction from the negative emotional pictures.The value of attentional bias and disengaging index were both significantly higher than 0 （P〈0.05 ）.Conclusion There are different characteristics of attention bias in patients with different types of rumination,sugges-ting the necessity for psychological intervention on the accidentally inj ured patients.
