行为抑制（BI）是一种以回避行为来应对新刺激的气质偏差，是创伤后应激障碍（PTSD）的危险因素。目前尚不清楚BI是否解释了PTSD症状严重程度的额外差异，而不仅仅是一般焦虑。在这里，109名退伍军人（平均年龄50.4岁，9.2%女性）提供了自我评估的PTSD症状，状态和特质焦虑，战斗暴露，和当前（成人）和回顾性（儿童）BI。成人HI与焦虑和PTSD症状严重程度相关，尤其是C组（回避）症状，但与战斗暴露无关。包括成人BI、状态和特质焦虑以及战斗暴露的回归模型能够根据严重PTSD症状的存在或不存在对超过80%的参与者进行正确分类。由于回避行为是PTSD的核心组成部分，BI的自我评估可能是理解PTSD和潜在评估易患该疾病的重要工具。出版社：Elsevier爱尔兰Ltd.
Behavioral inhibition (BI), a temperamental bias to respond to novel stimuli with avoidance behaviors, is a risk factor for posttraumatic stress disorder (PTSD). It is unclear whether BI accounts for additional variance in PTSD symptom severity beyond that accounted for by general anxiety. Here, 109 veterans (mean age 50.4 years, 9.2% female) provided self-assessment of PTSD symptoms, state and trait anxiety, combat exposure, and current (adult) and retrospective (childhood) BI. Adult HI was correlated with anxiety and PTSD symptom severity, especially cluster C (avoidance) symptoms, but not with combat exposure. A regression model including adult BI, state and trait anxiety, and combat exposure was able to correctly classify over 80% of participants according to presence or absence of severe PTSD symptoms. Because avoidance behaviors are a core component of PTSD, self-assessments of BI may be an important tool in understanding PTSD and potentially assessing vulnerability to the disorder.
