Eye Movement Desensitization & Reprocessing
EMDR is an individual therapy typically delivered one to two times per week for a total of 6-12 sessions, although some people benefit from fewer sessions.
The Adaptive Information Processing model considers symptoms of PTSD and other disorders that result from past disturbing experiences that continue to cause distress because the memory was not adequately processed. These unprocessed memories contain the emotions, thoughts, beliefs and physical sensations that occurred at the time of the event. When the memories are triggered these stored disturbing elements are experienced and cause the symptoms of PTSD and/or other disorders.
EMDR therapy focuses directly on the memory, and is intended to change the way that the memory is stored in the brain, thus reducing and eliminating the problematic symptoms.
During EMDR therapy, clinical observations suggest that an accelerated learning process is stimulated by EMDR’s standardized procedures, which incorporate the use of eye movements and other forms of rhythmic left-right (bilateral) stimulation (e.g., tones or taps). While clients briefly focus on the trauma memory and simultaneously experience bilateral stimulation (BLS), the vividness and emotion of the memory are reduced.
Structured 8-phase approach
History
In addition to getting a full history and conducting appropriate assessment, the therapist and client work together to identify targets for treatment. Targets include past memories, current triggers and future goals.
Preparation
The therapist offers an explanation for the treatment, and introduces the client to the procedures, practicing the eye movement and/or other BLS components. The therapist ensures that the client has adequate resources for affect management, leading the client through the Safe/Calm Place exercise.
Assessment
The third phase of EMDR, assessment, activates the memory that is being targeted in the session, by identifying and assessing each of the memory components: image, cognition, affect and body sensation.
Two measures are used during EMDR therapy sessions to evaluate changes in emotion and cognition: the Subjective Units of Disturbance (SUD) scale and the Validity of Cognition (VOC) scale. Both measures are used again during the treatment process, in accordance with the standardized procedures:
Desensitization
During this phase, the client focuses on the memory, while engaging in eye movements or other BLS. Then the client reports whatever new thoughts have emerged. The therapist determines the focus of each set of BLS using standardized procedures. Usually the associated material becomes the focus of the next set of brief BLS. This process continues until the client reports that the memory is no longer distressing.
Installation
The fifth phase of EMDR is installation, which strengthens the preferred positive cognition.
Body Scan
The sixth phase of EMDR is the body scan, in which clients are asked to observe their physical response while thinking of the incident and the positive cognition, and identify any residual somatic distress. If the client reports any disturbance, standardized procedures involving the BLS are used to process it.
Closure
Closure is used to end the session. If the targeted memory was not fully processed in the session, specific instructions and techniques are used to provide containment and ensure safety until the next session.
Reevaluation
The next session starts with phase eight, re-evaluation, during which the therapist evaluates the client's current psychological state, whether treatment effects have maintained, what memories may have emerged since the last session, and works with the client to identify targets for the current session.
