Acute Stress Disorder (ASD) in DSM-5 is defined to capture clinically significant, early reactions to trauma that occur within days to weeks of the event, so it can be identified and treated promptly. DSM-5 key points: ASD applies when symptoms begin within 3 days of the trauma and last from 3 days up to 1 month; if symptoms persist beyond 1 month, PTSD is considered. ASD requires a threshold of symptoms (nine or more) drawn from five symptom clusters (intrusion, negative mood, dissociation, avoidance, and arousal), reflecting a severe acute response.

Step-by-step reasoning:
1. Time course: ASD window = 3 days to 1 month after trauma. PTSD requires symptoms for more than 1 month. Therefore ASD is specifically the early diagnosis, not a replacement for later PTSD.
2. Clinical purpose: Including ASD in DSM-5 highlights people with severe immediate reactions and supports early identification and intervention—making them eligible for prompt clinical care to reduce suffering and potentially lower risk of chronic PTSD.
3. Predictive relationship: ASD is a predictor of PTSD risk—many who meet ASD criteria are at increased risk of developing PTSD—but it is not a guaranteed protective or exclusionary diagnosis.

Why the correct option is correct:
- The stated option accurately reflects DSM-5’s intent: to flag early severe trauma reactions and facilitate early treatment.

Why the other options are incorrect:
- Option 2: Incorrect because ASD is not used “instead of PTSD” when symptoms begin 6 months after trauma; delayed-onset PTSD is a separate issue and ASD is limited to the first month.
- Option 3: Incorrect because ASD often predicts higher risk for subsequent PTSD; saying “most do not eventually develop PTSD” is an overgeneralization and misleading.
- Option 4: Incorrect because not everyone exposed to trauma develops PTSD; only a subset do.

Conclusion: The correct answer is the first option: Acute stress disorder (ASD) is included in DSM-5 to highlight early severe reactions to trauma and to ensure that people experiencing ASD are eligible to receive immediate treatment.
