The American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) specifies that, for a diagnosis of ASD, at least nine of 14 symptoms from any of five categories—intrusion, negative mood, dissociation, avoidance, and arousal—must have begun or worsened after the traumatic event.
The other diagnostic criteria include the following:
Exposure to actual or threatened death, serious injury, or sexual violation either directly, through learning of or witnessing the event, or through experiencing repeated or extreme exposure to the aversive details of the event(s)
The duration of the disturbance is 3 days to 1 month after trauma exposure. ASD may progress to post-traumatic stress disorder (PTSD) after a month
The disturbance causes clinically significant distress or impairment in social, occupational, or other important areas of functioning
The disturbance cannot be attributed to the physiologic effects of a substance (eg, a medication or alcohol) or another medical condition (eg, mild traumatic brain injury) and cannot be better explained by a diagnosis of brief psychotic disorder
