公安民警的创伤后应激症状对执行功能的影响—基于Stroop范式的探究

摘要/Abstract

摘要： 公安民警常常身临应激和危险情境中，是创伤事件的易感人群，但其创伤后应激症状对执行功能的影响研究尚且缺乏。已有研究发现，具有创伤后应激症状的个体的执行功能存在缺陷，表现在对冲突信息的抑制能力受损以及对创伤相关信息的注意偏向和情绪唤起。本研究以公安民警为实验组被试，据其创伤后应激症状分为高低两组，在校大学生为对照组被试，采用Stroop范式探究创伤后应激症状对公安民警“冷”、“热”执行功能的影响。结果表明，具有创伤后应激症状的公安民警在“冷”、“热”执行功能上不存在缺陷，但仍在一定程度上受到创伤后应激症状的影响。启示对具有创伤后应激症状的公安民警进行干预时，应关注其症状的严重程度，在“热”执行功能上寻求更有效的干预方式。

Abstract: Confronting dangerous and stressful situations frequently, police officers are the susceptible population of traumatic events. However, there is still a lack of researches on the impact of post-traumatic stress symptoms (PTSS) on executive function among police officers. Previous studies have found that patients with post-traumatic stress symptoms have a defective executive function, which is manifested in impaired ability on suppressing conflict information, also manifested in attention bias and emotional arousal to trauma-related information. We recruited police officers as the experimental group, and divided them into two groups according to their PTSS level, while the college students were recruited as the control group. Stroop paradigm was adopted to explore the influence of post-traumatic stress symptoms on the “cold” and “hot” executive functions of police officers. Results indicated that the police officers with PTSS didn’t have a deficiency in executive function, however, they were still affected by PTSS. It is suggested that researchers should pay more attention to the severity of the symptoms of post-traumatic stress and seek more effective interventions according to the “hot” executive function.

Key words: posttraumatic stress symptom, executive function, the Stroop task, police officers
