The Current Evidence for Acute Stress Disorder

Area of Science:

• Psychiatry
• Trauma Studies
• Clinical Psychology

Background:

• Acute stress disorder (ASD) was conceptualized to predict posttraumatic stress disorder (PTSD).
• Understanding the trajectories of posttraumatic stress is crucial for effective intervention.
• Recent research challenges the predictive validity of ASD for PTSD.

Purpose of the Study:

• To review current evidence on the course of acute and chronic posttraumatic stress.
• To evaluate the diagnostic utility of ASD in predicting PTSD.
• To summarize effective treatments for ASD and prevention strategies for PTSD.

Main Methods:

• Review of longitudinal studies on posttraumatic stress trajectories.
• Analysis of latent growth mixture modeling in trauma-exposed populations.
• Synthesis of evidence on treatments for ASD and PTSD prevention.

Main Results:

• Longitudinal studies show ASD is not an accurate predictor of PTSD.
• Four distinct trajectories identified: resilient, worsening, recovery, and chronically distressed.
• Trauma-focused cognitive behavior therapy (CBT) is the treatment of choice for ASD, reducing chronic PTSD.
• Pharmacological interventions, like corticosterone, show promise in early PTSD prevention.

Conclusions:

• The complexity of posttraumatic stress courses limits ASD's predictive capacity.
• ASD diagnosis identifies individuals with severe distress post-trauma.
• Early provision of CBT is the most effective strategy for limiting subsequent PTSD.
