作者利用对口面部损伤幸存者（N = 264）的纵向研究数据，研究了体位应激障碍症状群之间的时间关系。他们进行了交叉滞后的小组分析，在损伤后1、6和12个月收集了自我报告的症状数据。结果表明，高唤醒是一个强有力的预测因素，随后的症状再体验和回避以及高唤醒。相比之下，随着时间的推移，再体验和回避都与其他症状群无关。这些发现强调了随着时间的推移，过度觉醒在创伤后心理困扰表现中的独特性质。对理论、临床干预和未来研究的意义进行了讨论。
The authors examined the temporal relation among posturaumatic stress disorder symptom clusters, using data derived from a longitudinal study of survivors of orofacial injury (N = 264). They conducted cross-lagged panel analyses, with self-reported symptom data collected at 1, 6, and 12 months postinjury. Results demonstrate that hyperarousal was a potent predictor of subsequent symptoms of reexperiencing and avoidance as well as hyperarousal. By contrast, neither reexperiencing nor avoidance was significantly related to other symptom clusters other than themselves over time. These findings underscore the distinctive nature of hyperarousal in the manifestation of posttraumatic psychological distress over time. Implications for theory, clinical intervention, and future research are discussed.
