Which of the following is included in reliving/re-experiencing trauma?

• A. Avoidant behaviors and emotional numbness
• B. Negative beliefs about the world
• C. Intrusive thoughts, memories, nightmares, or sensory triggers
• D. Hypervigilance and startle response

Answer: (C)

Reliving/re-experiencing trauma involves intrusive, involuntary experiences that pull you back into the traumatic event. This includes distressing memories or flashbacks, frightening dreams or nightmares about the event, and sensory cues (sounds, smells, sights) that suddenly trigger a vivid re-experience. These symptoms are characteristic of the intrusion or re-experiencing cluster of PTSD and are driven by the mind trying to process trauma without conscious control at times.

The other patterns represent different symptom clusters: avoidance and emotional numbness describe efforts to avoid reminders and a diminished range of emotions; negative beliefs about the world reflect cognitive and mood alterations such as pervasive mistrust or hopelessness; and hypervigilance with a heightened startle response denotes chronic arousal and readiness for danger. While related, they do not capture the hallmark of re-experiencing, which is the vivid, involuntary, distressing re-living of the trauma through thoughts, memories, nightmares, or sensory triggers.
