Objective: To explore the relationship between posttraumatic stress disorder (PTSD) and major depressive disorder (MDD) in veterans with spinal cord injury and to compare those results with results found in veterans who had sustained other traumatic injuries. Method. To investigate the relationship between PTSD and MDD in persons with spinal cord injury, the authors examined whether individuals endorsed overlapping items on measures of both disorders, evaluated the contribution of overlapping items to comorbid diagnosis, and conducted an exploratory factor analysis. Results: The overlapping symptoms between the 2 disorders did not fully explain the high rate of comorbidity, although participants who endorsed a symptom common to MDD and PTSD on I measure were likely to endorse the corresponding item on another measure. In both samples, items loaded on separate PTSD and MDD factors. Conclusion: MDD and PTSD appear to represent independent reactions to trauma in those individuals who had experienced either a nonspinal cord injury or a spinal cord injury. This research also provides an initial investigation of some of the possible ways that MDD and PTSD are related by addressing psychometric issues inherent in their measurement.
