The present investigation examined the impact of anxiety sensitivity (AS) and media exposure on posttraumatic stress disorder (PTSD) symptoms. Reactions from 143 undergraduate students in Hamilton, Ontario were assessed in the Fall of 2003 to gather information on anxiety, media coverage, and PTSD symptoms related to exposure to a remote traumatic event (September 11th). Regression analyses revealed that the Anxiety Sensitivity Index (ASI; [Peterson, R. A., & Reiss, S. (1992). Anxiety Sensitivity Index manual, 2nd ed. Worthington, Ohio: International Diagnostic Systems]) and State-Trait Anxiety Inventory trait form (STAI-T; [Spielberger, C. D., Gorsuch, R. L., & Lushene, R. E. (1970). State-trait anxiety inventory. Palo Alto, California: Consulting Psychologists Press]) total scores were significant predictors of PTSD symptoms in general. The ASI total score was also a significant predictor of hyperarousal and avoidance symptoms. Subsequent analyses further demonstrated differential relationships based on subscales and symptom clusters. Specifically, media exposure and trait anxiety predicted hyperarousal and re-experiencing symptoms, whereas the ASI fear of somatic sensations subscale significantly predicted avoidance and overall PTSD symptoms. Implications and directions for future research are discussed.
本研究考察了焦虑敏感性（AS）和媒体接触对创伤后应激障碍（PTSD）症状的影响。2003年秋季，对安大略省汉密尔顿市的143名本科生的反应进行了评估，以收集有关焦虑、媒体报道以及与接触远距离创伤事件（9·11事件）相关的PTSD症状的信息。回归分析显示，焦虑敏感性指数（ASI；[彼得森，R.A.，& 赖斯，S.（1992年）。《焦虑敏感性指数手册》，第2版。俄亥俄州沃辛顿：国际诊断系统公司]）和状态 - 特质焦虑量表特质形式（STAI - T；[斯皮尔伯格，C.D.，戈尔苏奇，R.L.，& 卢申内，R.E.（1970年）。《状态 - 特质焦虑量表》。加利福尼亚州帕洛阿尔托：咨询心理学家出版社]）总分总体上是PTSD症状的显著预测指标。ASI总分也是过度警觉和回避症状的显著预测指标。后续分析进一步证明了基于分量表和症状群的差异关系。具体而言，媒体接触和特质焦虑预测过度警觉和重新体验症状，而ASI对躯体感觉的恐惧分量表显著预测回避和总体PTSD症状。讨论了未来研究的意义和方向。
