Reexperiencing of the trauma, avoidance, and arousal, as defined in the criteria for PTSD, must also exist.

The focus of this disorder is on dissociative features, and, consequently, the symptom criteria include at least three of the following: a sense of numbing, detachment, or lack of emotional responsiveness, a reduction in awareness of surroundings (e.g., being in a daze), derealization, depersonalization, and dissociative amnesia.

The disadvantage is its rigidity and the possibility that one symptom can determine diagnostic membership.

Second, the ICD-IO does not recognize the numbing symptoms, which together with flashbacks and nightmares are thought to be cardinal features of PTSD.

Posttraumatic Stress Disorder, as described in DSM-IV, is a set of symptoms that begins after a trauma and persists for at least 1 month. First, the individual must reexperience the trauma in one of the following ways: nightmares, flashbacks, or intrusive and distressing thoughts about the event; or intense emotional distress or physiological reactivity when reminded of the event.

A diagnosis of Acute Stress Disorder is warranted when such symptoms last between 2 days and 1 month, occur within 1 month of the trauma, and interfere significantly with daily functioning.Adult assessment tools are reviewed in the next section.Although some measures have also been developed for children, they are outside the scope of this paper.These three criteria must all be met within 6 months of the traumatic event for a diagnosis to be given.Several differences between the two definitions can be identified. Thus, events such as anticipated death of a loved one, job loss, or divorce would not qualify as a trauma in this formulation. In the Diagnostic and Statistical Manual (DSM-IV) published by the American Psychiatric Association in 1994, a trauma is defined as an experienced or witnessed event that involves threat of death or serious injury, and which evokes feelings of terror, horror, or helplessness.For instance, it is not clear that the symptoms of behavioral avoidance and emotional numbing are similar and belong in the same category.The ICD-IO criteria for PTSD also include some reexperiencing symptoms (nightmares, flashbacks, distress on exposure to reminders), actual or preferred avoidance of trauma reminders, and either an inability to recall important aspects of the trauma or sustained psychological sensitivity and arousal (sleep disturbance, hypervigilance, difficulty concentrating).Third, arousal symptoms are optional in the ICD-IO but are required in the DSM-IE Clinical observation and theoretical accounts of PTSD support the importance of these symptoms and render the ICD-IO diagnostic criteria less satisfactory. For the majority of individuals, symptoms begin immediately after the trauma, although some appear to have a delayed reaction.During the first 3 months after the trauma, the individual is said to have acute PTSD, whereas chronic PTSD is defined as symptoms persisting beyond 3 months.
