Introduction: This thesis examined the impact of PTSD with Major Depressive Disorder on PTSD severity among Toronto Transit Commission employees who were exposed to a workplace traumatic event, and also the predictors of PTSD severity, mental health treatment seeking, and return to work over the six month study period.
Methods: This study utilized data that was collected prospectively from the APT study participants. Information about Axis-I diagnosis and PTSD severity were collected from the SCID-I and the Modified PTSD Symptom Scale respectively.
Results: PTSD without MDD (N=29) and PTSD with MDD (N=37) groups were compared. The variables: depression severity (p=0.01), female (p=0.01), non-Caucasian (p=0.01), workplace related stress (p=0.02), and lifetime trauma (p=0.01) significantly predicted PTSD severity. The BPI group significantly predicted mental health treatment seeking (p<0.01) after controlling other variables.
Conclusion: This study highlights the substantial risk for experiencing greater PTSD severity after a workplace traumatic event in TTC employees.
