Posttraumatic Growth Following the Terrorist Attacks of September 11, 2001: Cognitive, Coping, and Trauma Symptom Predictors in an Internet Convenience Sample

Abstract

Cognitive, coping, and trauma symptom predictors of posttraumatic growth (PTG; measured with the Posttraumatic Growth Inventory) were examined in a large convenience sample (n =1505) participating in a longitudinal Internet-based study following the terrorist attacks of 9/11/01. Results indicate that initial PTG levels (mean 9 weeks post-attacks) were generally associated with higher trauma symptoms (measured with the PTSD Checklist - Specific), positive changes in worldview (measured with the Changes in Outlook Questionnaire), more denial, and less behavioral disengagement (measured with the Brief COPE). Additionally, PTG had a curvilinear association with level of trauma symptoms, such that those reporting symptoms at intermediate levels reported the highest levels of growth. Levels of PTG declined somewhat over time with the exception of Spiritual Change. As expected, PTG levels at follow-up (mean 6.5 months post-attacks) were primarily predicted by initial PTG levels; however, decreases from baseline ...
