Final answer:
Option E (Experiencing repeated exposure to aversive details of a traumatic event) is not a criterion of PTSD. The correct criteria for PTSD include reexperiencing the event, increased arousal, and avoidance of stimuli associated with the trauma, with symptoms lasting more than one month, not 'more than 2 months' as mentioned in option D.
Step-by-step explanation:
To answer the question which one of the following is not a criterion of posttraumatic stress disorder (PTSD), option E, Experiencing repeated exposure to aversive details of a traumatic event, is not a criterion of PTSD as listed in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) by the American Psychiatric Association. Instead, the criteria for PTSD include reexperiencing the traumatic event (A), increased arousal (B), avoidance of stimuli associated with the trauma (C), and the requirement that the duration of the disturbance is more than one month (D). The criterion related to duration contradicts the assertion mentioned in option D, which incorrectly states 'more than 2 months'. It is also important to clarify that exposure to the initial traumatic event is a prerequisite for PTSD, but repeated exposure to aversive details is not a criterion for the disorder itself, though it may exacerbate symptoms.
