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.

  • Provides resources and lists of psychological treatments with published evidence of efficacy.

  • List intended for a diverse audience including clinicians, educators, researchers, and the public.

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.
