Which of the following is a common symptom of PTSD in officers?

Flashbacks are indeed a common symptom of PTSD, particularly among officers who may have experienced traumatic events in the line of duty. Flashbacks are intense and vivid re-experiences of the trauma, where individuals feel as though they are reliving the event. This symptom can be incredibly distressing and disruptive, affecting an officer's ability to function in their personal and professional life.

In the context of law enforcement, experiencing flashbacks can be triggered by reminders of the traumatic incident, such as sounds, smells, or other sensory inputs related to the event. This makes it vital for officers to receive appropriate support and interventions to manage PTSD symptoms effectively. In contrast, the other options do not align as closely with the typical symptoms associated with PTSD, making flashbacks the most recognizable symptom in this context.
