This study tested a conceptual model merging anxiety buffer disruption and social-cognitive theories to predict persistent grief severity among students who lost a close friend, significant other, and/or professor/teacher in tragic university campus shootings. A regression-based path model tested posttraumatic stress (PTS) symptom severity 3 to 4 months postshooting (Time 1) as a predictor of grief severity 1 year postshootings (Time 2), both directly and indirectly through cognitive processes (self-efficacy and disrupted worldview). Results revealed a model that predicted 61% of the variance in Time 2 grief severity. Hypotheses were supported, demonstrating that Time 1 PTS severity indirectly, positively predicted Time 2 grief severity through undermining self-efficacy and more severely disrupting worldview. Findings and theoretical interpretation yield important insights for future research and clinical application.
本研究通过融合焦虑缓冲破坏和社会认知理论，检验了一个概念模型，以预测在悲剧性的大学校园枪击事件中失去亲密朋友、重要他人和/或教授/教师的学生持续的悲伤严重程度。基于回归的路径模型检验了创伤后应激（PTS）症状严重程度在枪击事件发生后 3 至 4 个月（时间 1）作为枪击事件发生后 1 年（时间 2）悲伤严重程度的直接和间接预测指标，通过认知过程（自我效能和世界观破坏）。结果显示，该模型可以预测时间 2 悲伤严重程度的 61%。假设得到了支持，表明时间 1 PTS 严重程度通过破坏自我效能和更严重地破坏世界观，间接地、积极地预测了时间 2 悲伤严重程度。研究结果和理论解释为未来的研究和临床应用提供了重要的见解。
