How does ASD differ from PTSD regarding timing?

• A. ASD occurs within 3 days to 1 month after trauma; PTSD symptoms persist beyond 1 month.
• B. ASD duration is the same as PTSD.
• C. ASD lasts more than a year.
• D. PTSD can be diagnosed after months of symptoms.

Answer: (A)

Timing is the key difference. Acute Stress Disorder occurs when symptoms begin within 3 days to 1 month after the traumatic event and are limited to that early post-event period. If symptoms persist beyond 1 month, the diagnosis is Posttraumatic Stress Disorder, reflecting a more prolonged pattern. This distinction matters because ASD can indicate who is at risk for developing PTSD and may prompt early intervention. The other statements don’t fit because ASD is not defined as lasting longer than a month, and PTSD is not defined as requiring symptoms that appeared after several months—rather, it requires symptoms to persist beyond one month after the trauma.
