Objective. Epidemiological research has examined post-traumatic stress disorder (PTSD) related to the World Trade Center (WTC) attacks on September 11, 2001 (9/11) in the general population. However, there is a paucity of work documenting the consequences among those most directly affected by the disaster. This dissertation determined the prevalence of PTSD among tower survivors and examined whether social structure and direct exposure were PTSD risk factors.

520 $a Objective. Epidemiological research has examined post-traumatic stress disorder (PTSD) related to the World Trade Center (WTC) attacks on September 11, 2001 (9/11) in the general population. However, there is a paucity of work documenting the consequences among those most directly affected by the disaster. This dissertation determined the prevalence of PTSD among tower survivors and examined whether social structure and direct exposure were PTSD risk factors.
520 $a Methods. The sample included 3,271 adults who evacuated WTC Towers 1 and 2 on 9/11. Purposive sampling via employer and security badge lists was used along with self-enrollment via telephone or web. Baseline data was collected between 9/2003 and 11/2004. Probable PTSD was measured using the PTSD Checklist. Direct exposure was operationalized through details of respondents' experiences on September 11. Univariate procedures were used to describe the prevalence of PTSD. Logistic regression was used to identify the independent effects of social structure and direct exposure on PTSD. A score was created and tested to describe the cumulative effect of direct exposures on PTSD.
520 $a Results. Prevalence estimates of current PTSD ranged from 15.0% (based on a PCL score=50+) to 22.3% (based on DSM-IV criteria). Women and minorities were more likely to screen positive. After controlling for other risk factors, a strong inverse relationship was observed between household income and PTSD. Direct exposure stressors predicting PTSD in a multivariable model included late evacuation, dust cloud exposure, witnessing horror, injury, and working for a company with 9/11 fatalities. A cumulative effect of direct exposure was observed in which an increase of life threat stressors experienced on 9/11 resulted in an increase of post-traumatic stress symptoms and PTSD.
520 $a Conclusion. A few years after the WTC attacks, significant amounts of post-traumatic stress symptoms and PTSD were observed among tower survivors. While survivors shared a collective experience on 9/11, individuals who were of lower social status or exposed to the most life threatening or disturbing stressors were at the greatest risk for PTSD. These findings suggest the effect of 9/11 is long-lasting. Further research is warranted on the course of PTSD and comorbidity with other sequelae.
