Eye movement desensitization and reprocessing (EMDR) therapy is a highly effective treatment for trauma, anxiety, and other mental health issues. Unlike traditional talk therapy, which can take years to uncover and process painful memories, EMDR follows a structured, research-backed process that often leads to improvements in a relatively short period of time. If you’re considering EMDR, you might wonder whether it has a set timeline.
The answer: yes and no. EMDR is highly structured, but the duration of therapy varies based on individual needs, history, and the complexity of a person’s trauma. Here are the factors that influence the timeline of EMDR therapy and what you can expect.
The Eight Phases of EMDR and Their Timeline

EMDR’s structured approach is designed to help clients process distressing memories and reduce their emotional intensity. Each phase contributes to the overall timeline:
1. History-taking and treatment planning
The therapist gathers information about your history, symptoms, and treatment goals.
Duration: This can take one to several sessions, depending on the complexity of your history.
2. Preparation
The therapist helps you build coping skills and emotional regulation techniques.
Duration: One to four sessions, though more may be needed for those with more serious emotional dysregulation.
3. Assessment
You and your therapist determine the specific memories to target and establish your baseline distress levels.
Duration: Usually a single session per memory, but more may be needed for complex trauma.
4. Desensitization
Using bilateral stimulation (eye movements, tapping, or auditory tones), the therapist helps you reprocess the target memory.
Duration: Some people experience relief in a single session, while others require multiple sessions per memory.
5. Installation
Your therapist helps you install positive beliefs about yourself to replace negative thoughts associated with the trauma.
Duration: Typically, part of the same session is desensitization, but additional time may be needed.
6. Body scan
Afterward, you’ll check for residual distress in your body and address any lingering sensations.
Duration: Often brief, but may require extra work for people with trauma stored in the body.
7. Closure
Your therapist ensures you’re emotionally stable before ending a session.
Duration: A few minutes to a full session, depending on the level of distress.
8. Reevaluation
Together, you and your therapist review your progress and decide whether further processing is needed.
Duration: Ongoing throughout therapy.
Factors in the duration of EMDR therapy
While EMDR does follow a structured schedule, individual timelines vary. Some important factors include:
Complexity of trauma: Single-event traumas (e.g. a car accident) often take fewer sessions to process than complex trauma (like prolonged abuse or childhood neglect).
Number of target memories: Someone with several distressing memories will have a longer treatment process.
Emotional readiness: Some clients require more time in the preparation phase to build coping strategies before they can safely engage in trauma processing.
Co-occurring conditions: Anxiety, depression, or dissociation can impact how quickly someone progresses through EMDR. These conditions might affect how ready they are to use coping strategies or how distressed they feel after the installation phase.
Session frequency: Weekly or biweekly sessions generally lead to faster results compared to less frequent therapy.
How Long Does EMDR Take for Most People?
For some, EMDR can ease symptoms in as few as three to six sessions. This is more common for people working through a single traumatic event or memory. For those with more complex trauma, treatment can take months or even longer. A typical course of EMDR ranges from 6 to 20 sessions, but there is no universal timeline — it’s unique to each person’s needs.
