What is secondary traumatic stress and how does it differ from PTSD?

• A. STS is identical to PTSD.
• B. STS results from direct exposure to trauma; PTSD results from indirect exposure.
• C. STS results from exposure to others' trauma and shares symptoms like intrusion and hyperarousal, but it stems from vicarious exposure; PTSD arises from directly experiencing a traumatic event.
• D. STS is unrelated to caregiving work.

Answer: (C)

Secondary traumatic stress is the distress that develops in people who are repeatedly exposed to others’ traumatic experiences through their work. It can produce symptoms similar to PTSD—such as intrusive thoughts or images, hyperarousal, sleep disturbance, and avoidance—but these arise from vicarious exposure, not from a traumatic event happening to the observer.

The essential distinction is the source of exposure. STS comes from hearing about or witnessing others’ trauma as a result of caring for them or working with trauma survivors. PTSD, on the other hand, stems from directly experiencing or witnessing a traumatic event yourself (or in some cases, learning that a close family member was exposed to such an event). So, the option describing STS as arising from exposure to others’ trauma and sharing similar symptoms, but rooted in indirect/vicarious exposure, while PTSD arises from direct personal experience, best captures the difference.
