Conservation of resources (COR) theory has proven a useful framework for understanding posttrauma adjustment. A key tenet of this theory is the centrality of resource loss in determining adjustment. However, COR theory research has often been limited by retrospective research design, a focus on material loss (e.g., one's home), and a lack of attention to other adjustment predictors. This study examined whether psychosocial resource loss prospectively predicted PTSD symptomatology both immediately and 8 months following a campus shooting in a sample of college women (n = 691). Results supported that resource loss predicted symptomatology, even after controlling for other predictors, including prior trauma, psychological distress, initial PTSD symptomatology, and shooting exposure. Implications of the results for research and intervention following mass trauma are discussed.
资源守恒（COR）理论已被证明是理解创伤后适应的一个有用框架。该理论的一个关键原则是资源损失在决定适应方面的核心地位。然而，COR理论研究常常受到回顾性研究设计的限制，专注于物质损失（如个人的家），且缺乏对其他适应预测因素的关注。本研究考察了心理社会资源损失是否能前瞻性地预测大学女生样本（n = 691）在校园枪击事件后即刻及8个月时的创伤后应激障碍（PTSD）症状。结果支持了资源损失能预测症状，即使在控制了其他预测因素之后，这些因素包括既往创伤、心理困扰、初始PTSD症状以及枪击暴露。讨论了研究结果对大规模创伤后研究和干预的意义。
