The basic principles of therapeutic intervention for acute stress disorder are promptness, proximity, conciseness, and tight focus. Because the disorder is caused by an intensely stressful life event, psychotherapy is of great importance. Getting the patient out of the traumatic environment and avoiding further stimulation as soon as possible is of primary importance; establishing a good doctor-patient relationship, talking with the patient on a knee-to-knee basis, and providing interpretive and supportive psychotherapy to the patient may achieve good results when the patient is accessible; helping the patient to establish a self-referential and powerful psychological stress coping style, to play a personal buffering role, and to avoid excessive harm; and not avoid discussing the stressful event with the patient, but rather ask the patient to recall in detail what happened, what the patient saw and did. Such a discussion will help reduce the negative evaluation of their feelings that some patients may have. Patients should be told that in most cases, people are unlikely to do more satisfactorily when faced with an emergency accident. Medications are primarily symptomatic, but they are also one of the measures taken in the acute phase. Appropriate medication can provide faster relief of the patient’s symptoms and facilitate the development and effectiveness of psychotherapy.
