PTSD is a diagnosis that is quite often made by psychiatrists after a single interview for say an hour. It is important that additional information is gathered and evaluated in relation to the diagnostic criteria. DSM-IV is quite demanding in the clinical features that compose the syndrome.

Our assessment of a person with who has been exposed to trauma will probably be at least 2.5 hours. We gather much background information and if necessary may interview reliable informants to corroborate symptoms, loss of mental function and other relevant detail. Diagnosis is not a tick-box exercise. We explore the reality of the clients symptoms and connect that to any functional issues.

Our assessments may include psychometric testing as an adjunct to clinical diagnosis. See the criteria below.

Diagnostic criteria for 309.81 Posttraumatic Stress Disorder in DSM-IV:

1. The person has been exposed to a traumatic event in which both of the following were present:
   1. the person experienced, witnessed, or was confronted with an event or events that involved actual or threatened death or serious injury, or a threat to the physical integrity of self or others
   2. the person’s response involved intense fear, helplessness, or horror. Note: In children, this may be expressed instead by disorganised or agitated behaviour
2. The traumatic event is persistently reexperienced in one (or more) of the following ways:
   1. recurrent and intrusive distressing recollections of the event, including images, thoughts, or perceptions. Note: In young children, repetitive play may occur in which themes or aspects of the trauma are expressed.
   2. recurrent distressing dreams of the event. Note: In children, there may be frightening dreams without recognisable content.
   3. acting or feeling as if the traumatic event were recurring (includes a sense of reliving the experience, illusions, hallucinations, and dissociative flashback episodes, including those that occur on awakening or when intoxicated). Note: In young children, trauma-specific reenactment may occur.
   4. intense psychological distress at exposure to internal or external cues that symbolise or resemble an aspect of the traumatic event
   5. physiological reactivity on exposure to internal or external cues that symbolise or resemble an aspect of the traumatic event
