EMDR Therapy and Effectiveness
EMDR – Eye Movement Desensitization and Reprocessing in PTSD
Overview of EMDR Therapy
EMDR is a psychotherapy treatment designed to alleviate distress associated with traumatic memories.
Phases of EMDR Therapy
Phase 1: History and Treatment Planning
Discussion of the client's history and development of a treatment plan.
Attention to pacing of therapy and selection of traumatic events for treatment.
Assessment of the client’s internal and external resources.
Phase 2: Preparation
The therapist explains the EMDR therapy process, terminology, and sets expectations for therapy.
Collaboration between therapist and client to prepare techniques for coping with emotional disturbances.
Some clients may require extended time in Phases 1 and 2 to feel prepared for subsequent phases.
Phase 3: Assessment
Identification of the target event for reprocessing.
This includes gathering related images, beliefs, feelings, and physical sensations pertaining to the event.
Initial baseline measures are established to track progress.
Phase 4: Desensitization
Utilization of bilateral stimulation through side-to-side eye movements, sounds, or taps while focusing on the traumatic event.
This phase continues until the client’s Subjective Units of Distress (SUD) rating reduces to zero (or to a score of 1 if appropriate).
New thoughts, sensations, images, and feelings may emerge during this process.
Phase 5: Installation
Once desensitization is complete, the focus shifts to strengthening a positive belief related to the target event.
The client works to associate the positive belief until it feels fully true and authentic.
Phase 6: Body Scan
The client holds the target event and the positive belief in mind while scanning their body from head to toe.
Any lingering physical disturbances associated with the memory are reprocessed and addressed.
Phase 7: Closure
Each reprocessing session concludes with closure; assisting the client to return to a state of calm regardless of reprocessing completeness.
An event is deemed fully reprocessed when the client feels neutral about it, the positive belief feels completely true, and there is no physical disturbance reported.
Phase 8: Reevaluation
Each new session begins with a reevaluation of previously processed memories.
The therapist and client discuss any remaining distress and the strength of the positive cognition.
Future target events and treatment directions are established at this stage.
Ethics of Efficiency
Exploration of ethical and legal issues surrounding the efficiency of therapies.
Effectiveness and Efficiency of EMDR
Effectiveness
Examines whether the therapy has any impact on alleviating symptoms of PTSD.
Efficiency
Addresses how quickly the therapy works and the time commitment required.
Comparison to other therapies regarding speed and efficacy.
The intersection of ethics and therapeutic efficiency is discussed.
Measures of Efficiency
Research methodologies include randomized control trials evaluating symptoms as objective outcome measures.
Requires appropriate control and experimental groups.
Use of meta-analysis to synthesize multiple results and determine overall effect sizes.
Client satisfaction is also a critical measure of therapy outcome and efficiency.
Control Groups in Research
Discusses types of control groups that may be utilized:
Placebo control group.
Waitlist control group.
Non-treatment control group.
Non-directive supportive therapy (NDST) as per Carl Rogers' principles.
The counselor-client relationship dynamic, emphasizing unconditional positive regard and person-centered techniques to foster self-knowledge.
Considerations Before Implementing a Method
Understand the method thoroughly along with the evidence supporting its effectiveness.
Recognize the boundaries and limitations of the method's effectiveness.
Communicate these limitations clearly with clients.
Maintain a critical perspective toward the method's community and its practices.
Evidence Supporting EMDR Therapy
Study 1: Individual Trauma-Focused Cognitive Behavioral Therapy (TFCBT) and EMDR are found to be equally effective in treating PTSD.
Study 2: EMDR and brief eclectic psychotherapy are both effective for PTSD, with EMDR showing a faster reduction in symptoms.
Study 3: EMDR therapy demonstrated greater improvements compared to non-trauma-focused CBT in treating oncological patients.
Study 4: EMDR is reported to be no more effective than other exposure techniques, and the eye movements may not be necessary for treatment efficacy.
Society of Clinical Psychology
American Psychological Association's Division 12 has identified best research evidence as a major component of evidence-based practice.

Theoretical Example of Therapy
Purple Hat Therapy Hypothetical Case: A doctor may suggest that clients with driving phobias wear a large purple hat while using relaxation and cognitive coping skills in real-life practice scenarios, illustrating an innovative therapeutic approach (Rosen & Davidson, 2003).
Pitfalls of Choosing a Method
Risk factors include:
Reliance on anecdotal evidence.
Influence of peer pressure.
Confirmation bias influencing outcomes.
Publication bias affecting visibility of positive versus negative results in the literature.
