我们提出的概念基础和经验证据考虑回避和麻木作为不同的创伤后应激障碍（PTSD）症状群。大部分的数据从因素分析研究支持的立场，回避和麻木是不同的症状群。此外，现有数据表明：（a）不同的治疗方式对减少回避但不减少麻木有不同的效果，（B）治疗前麻木更严重的患者治疗效果较差，（c）回避和麻木与抑郁症的相关性不同，（d）它们与注意力生理指标的相关性不同。我们的结论是，回避和麻木是不同的PTSD症状集群。这一区别对修订现行诊断标准具有重要意义。认识到这种区别可能会导致对PTSD的理解和治疗的进步。
We present the conceptual basis and empirical evidence for considering avoidance and numbing as distinct posttraumatic stress disorder (PTSD) symptom clusters. The majority of data from factor analytic studies supports the position that avoidance and numbing are distinct symptom clusters. As well, the available data suggest that (a) different treatment modalities have differential effects on reducing avoidance but not numbing, (b) patients with more severe pretreatment numbing have poorer treatment outcomes, (c) avoidance and numbing have different patterns of correlation with depression, and (d) they have different correlations with physiological indices of attention. We conclude that avoidance and numbing are distinct PTSD symptom clusters. This distinction has implications for revising current diagnostic criteria. The recognition of this distinction may lead to advances in understanding and treating PTSD.
