Symptom counts as the basis for Post-Traumatic Stress Disorder (PTSD) diagnoses in the DSM presume each symptom is equally reflective of underlying disorder severity. However, the “equal weight” assumption fails to fit PTSD symptom data when tested. The present study developed an enhanced PTSD diagnosis based on (a) a conventional PTSD diagnosis from a clinical interview and (b) an empirical classification of full PTSD that reflected the relative clinical weights of each symptom.

不同症状权重估计潜在 PTSD 严重程度的经验阈值：迈向诊断的“白金”标准？

DSM 中的症状被视为创伤后应激障碍 (PTSD) 诊断的基础，假定每种症状同样反映了潜在疾病的严重程度。然而，在测试时，“等权”假设并不符合 PTSD 症状数据。本研究基于（a）来自临床访谈的传统 PTSD 诊断和（b）反映每种症状的相对临床权重的完整 PTSD 的经验分类，开发了一种增强的 PTSD 诊断。
