Trauma- and stressor-related disorders involve the exposure to a stressful or traumatic event. These were previously considered anxiety disorders, but are now considered a distinct category of disorders.
Disorders included in this category include:
- Acute stress disorder
- Adjustment disorders
- Post-traumatic stress disorder
- Reactive attachment disorder
This classification of mental disorders is related to an identifiable source of stress that causes significant emotional and behavioral symptoms.
The diagnostic criteria listed by the DSM-IV diagnostic criteria included:
- (1) Distress that is marked and excessive for what would be expected from the stressor and
- (2) Creates significant impairment in school, work or social environments.
In addition to these requirements, the symptoms must occur within three months of exposure to the stressor, the symptoms must not meet the criteria for an Axis I or Axis II disorder, the symptoms must not be related to bereavement and the symptoms must not last for longer than six months after exposure to the stressor.
