Industrial workers have shown high rates of trauma exposure in addition to high rates of posttraumatic stress disorder (PTSD) and major depressive disorder (MDD). While previous research has studied the symptoms of PTSD after trauma, none have examined PTSD and MDD symptoms together. In a sample of 182 Canadian industrial workers after trauma exposure, exploratory factor analyses (EFA) were conducted using item responses from the PTSD Checklist-5 (PCL-5), a measure of PTSD, and the Patient Health Questionnaire-9 (PHQ-9), a measure of depression. This study initially used an EFA on the item responses of the PCL-5 to assess the factor structure of PTSD symptoms, revealing a three-factor structure. A second EFA was conducted using the item responses to the PCL-5 and PHQ-9, to examine the association between PTSD and MDD following trauma and resulted in depression accounting for the preponderance of distress in the four factors that resulted. The resulting structure from examining PTSD and MDD symptoms together provides a greater understanding of emotional distress following an occupational trauma. Limitations, implications, and suggestions for future research are presented.
