该研究调查了理论推导的认知变量预测创伤后应激障碍（PTSD）、旅行恐惧症和机动车事故（MVA）受伤后抑郁症的能力。MVA幸存者（N = 147）在事故发生当天以及2周、1个月、3个月和6个月后在急诊科接受评估。诊断建立与DSM-IV的结构化临床访谈。预测因子包括初始症状的严重程度、E. J. Ozer，S. R.最好的T L. Lipsey和D. S.韦斯（2003）荟萃分析;以及来自PTSD、恐惧症和抑郁症认知模型的变量。非参数多元回归分析的结果表明，认知变量预测随后的创伤后应激障碍和抑郁症的严重程度超过和以上可以预测从最初的症状水平。它们也显示出比已建立的预测因子更大的预测能力，尽管后者显示出与荟萃分析相似的效应大小。此外，来自PTSD和抑郁症的认知模型的预测因子是疾病特异性的。研究结果支持认知因素在创伤后情绪障碍的维持中的作用。
The study investigated the power of theoretically derived cognitive variables to predict posttraumatic stress disorder (PTSD), travel phobia, and depression following injury in a motor vehicle accident (MVA). MVA survivors (N = 147) were assessed at the emergency department on the day of their accident and 2 weeks, 1 month, 3 months, and 6 months later. Diagnoses were established with the Structured Clinical Interview for DSM-IV. Predictors included initial symptom severities; variables established as predictors of PTSD in E. J. Ozer, S. R. Best, T. L. Lipsey, and D. S. Weiss's (2003) meta-analysis; and variables derived from cognitive models of PTSD, phobia, and depression. Results of nonparametric multiple regression analyses showed that the cognitive variables predicted subsequent PTSD and depression severities over and above what could be predicted from initial symptom levels. They also showed greater predictive power than the established predictors, although the latter showed similar effect sizes as in the meta-analysis. In addition, the predictors derived from cognitive models of PTSD and depression were disorder-specific. The results support the role of cognitive factors in the maintenance of emotional disorders following trauma.
