Which of the following events is most likely to result in post-traumatic stress disorder (PTSD)? 
Select and explain. 
A. Divorce, B. Bankruptcy, C. Diagnosis of diabetes mellitus, D. Robbery at knifepoint
D: Robbery at knifepoint
Answer: D: Robbery at knifepoint 
Explanation: Robbery at knifepoint, a life-threatening event, is most likely to result in post-traumatic stress disorder (PTSD). While life events such as divorce, bankruptcy, illness, and changing residence are stressful, they are rarely life-threatening. Psychological symptoms occurring after such less severe events may result in adjustment disorder, not PTSD.
