Criterion A2 causes many controversies in the diagnostic process of posttraumatic stress disorder (PTSD) among young children. Depending on the manner in which the trauma is indirectly experienced, clinical picture of disorder could be formed by different groups of symptoms. Profiles of symptoms groups are dependent of children ability to speak, describe or of play observation by expert.

The study included 8 children younger than 6 with PTSD diagnosis. Children were observed in a routine clinical practice.

Examinees under the age of six, whose can describe traumatic event, produce symptoms that represent compaction of a traumatic event, associated with fantasies and meanings related to previous traumatic experiences. Reexperiencing symptoms associated with A2 criterion (intrusive thoughts, images, scenes of the traumatic event, recurring nightmares with oneiric sequences of the accident) were rare. Avoidance and inhibited reactions were attributable.

Manners in which children younger than 6 experienced the trauma shows a large range from florid symptoms stated by the existing accepted classification. The results point out possible multifactorial cause of PTSD etiology.
