摘　　要：目的:考察不同创伤后成长(PTG)水平意外创伤者的注意偏向特点。方法:采用简体中文版创伤后成长问卷筛选出15名高分组被试和15名低分组被试,以积极、消极和中性表情图片为实验材料进行2(表情对性质:正性、负性)×2(探测点与表情图片一致性:一致、不一致)×2(高PTG水平、低PTG水平)混合设计的点探测实验。结果:低PTG水平的伤者对负性情绪表情图片存在注意偏向和注意脱离困难,注意偏向值(D)和脱离指数(DI)均显著大于0(P<0.05);高PTG水平的伤者对正性和负性情绪刺激均不存在注意偏向;在探测点与负性情绪表情图片位置不一致时,高PTG水平伤者的反应时要显著少于低PTG水平伤者,P<0.05。结论:PTG水平不同的伤者对情绪刺激的注意偏差存在不同,两者具有不同的内隐认知加工方式,可据此指导意外创伤者心理干预的开展。Objective： To explore the characteristics of attention bias in accidentally injured patients with different levels of Posttraumatic growth（PTG）. Methods： Total score of PTG was adopted to screen out 15 high-PTG group and low- PTG group respectively among accidentally injured patients. Dot probe task was used with positive, negative and neutral facial expression pictures as experimental materials. An experimental design of 2（facial expression： positive and negative）×2 （consistency of probe point and facial expression： consistent and inconsistent）~ 2（PTG level： high and low） was employed. Results： Patients with low PTG level had attention bias toward the negative emotional stimuli, and difficulty in distraction from the negative emotional pictures. The value of D and DI were both significantly greater than 0（P〈0.05）. Patients with high PTG level did not demonstrate significant attention bias toward positive or negative emotional stimuli. The responding time of patients with high PTG level was significantly shorter than that in patients with low PTG level in the incongruent task （P〈0.05）. Conclusion： There are different characteristics of implicit cognitive processing in patients with different level of PTG, suggesting the necessity of psychological intervention on the accidentally injured patients.
