One EMDR session may be enough to make meaningful progress with a target, while some concerns may benefit from additional sessions over time.

Is One EMDR Session Enough?

Short Answer: One Eye Movement Desensitization and Reprocessing (EMDR) session may be enough to make progress with a particular target, but there is no set number of sessions that works for everyone. Some targets may change noticeably in one session, while others may take several sessions or be connected to other memories, thoughts, emotions, or beliefs that you want to work with separately. You do not need to decide in advance exactly how many EMDR sessions you will need. You can see how a session goes and decide whether there is more you want to work on.

Key Takeaways

  • One EMDR session may be useful, but it is not possible to predict that one session will be enough for everyone.
  • A specific target may change significantly during one session, while another may take longer.
  • The number of sessions can depend on what you are working on and how the process unfolds.
  • You do not have to completely process a target in one sitting.
  • More sessions are not automatically better if you already feel you have accomplished what you wanted with a target.
  • You can return to the same target later or work with a different target in another session.
  • With self-guided EMDR, you can decide whether and when you want to do another session.

Can EMDR Work in Just One Session?

It can be useful to separate two questions:

Can something change during one EMDR session?

Yes.

Does that mean one session will always be enough?

No.

During an EMDR session, you focus on a target while using bilateral stimulation, such as guided eye movements, alternating sounds, or tapping. As the session progresses, the way you think or feel about the target may change.

For some targets, that change may happen relatively quickly.

For others, you may reach the end of the session and feel that there is still more you want to work on.

Both experiences are possible.

There is no requirement that every target take a certain number of sessions.

What Does “Enough” Mean?

The word “enough” can mean several different things.

You might be asking whether one session is enough to:

  • Notice some change
  • Feel differently about a particular memory
  • Reduce how upsetting a target feels
  • Work through one specific issue
  • Address everything connected to a larger problem

Those are not necessarily the same goal.

For example, you might notice a meaningful change in one memory during a single session but still have other memories or situations that you want to address later.

That does not make the first session incomplete.

It simply means that one session addressed one part of what you wanted to work on.

For someone working with memories or emotional reactions connected to phobias, one target may feel different from another in how much work it needs.

Some Targets May Take More Than One Session

EMDR targets can differ considerably.

A particular memory may feel specific and contained. Another target may connect with several other memories, thoughts, emotions, beliefs, or physical sensations.

As you work with one target, you may also notice something else that you want to address.

For example, a memory that initially seemed like the main issue may remind you of an earlier experience or a related situation.

You do not have to work through all of that material at once.

You can stop at a reasonable point and decide later whether you want to return to the original target or work with something else.

This is one reason the number of EMDR sessions can vary.

One Session Can Still Be Meaningful Even If You Continue Later

Needing or wanting another session does not erase what happened during the first one.

You may notice that a memory feels less upsetting even though it still bothers you somewhat.

You may notice that a negative belief feels less convincing.

You may think about the event differently.

Or you may simply notice that something has shifted without feeling that the target is completely resolved.

Those changes can still be meaningful.

EMDR does not have to produce an all-or-nothing result in a single sitting.

If you decide to return to the target later, the next session can begin from where you are then rather than treating the first session as if it did not count.

Do You Have to Finish a Target in One Session?

No.

There is no requirement that you completely work through a target every time you begin an EMDR session.

Sometimes you may reach a natural stopping point before the target feels completely different.

You can stop there.

You can return to it in another session if you want to continue.

This is especially useful to remember with self-guided EMDR because you control when the session ends.

You do not need to extend a session simply because you want to finish everything that day.

EMDR can take place across multiple sessions.

How Do You Know Whether You Want Another Session?

After a session, you can notice how the target feels rather than immediately deciding that you either must or must not do more EMDR.

You might ask yourself:

  • Does this memory still feel like something I want to work on?
  • Has the way I think about it changed?
  • Does the issue still feel important to address?
  • Did another related target come to mind?
  • Do I feel satisfied with where I stopped?

These questions are not a test.

They are simply ways to decide whether there is more you want to work with.

If the target no longer feels important to continue with, you do not need another session simply to increase your session count.

If there is more you want to address, you can return to it.

Does One Session Have to Make the Memory Stop Bothering You?

No.

A useful EMDR session does not have to end with a memory feeling completely neutral.

Changes can happen gradually.

You may notice that the memory feels somewhat less upsetting, that a particular thought has shifted, or that you see the experience differently.

At another session, you may notice further changes.

There is no need to judge the entire process based on whether everything changed in one sitting.

Likewise, if you notice a substantial change during one session, you do not have to assume that you need several more sessions simply because EMDR is usually described as a multi-session process.

What matters is what remains relevant for you to work on.

Can a Simple Target Take Less Time?

Potentially.

A specific, clearly defined target may sometimes require less time than an issue connected to many experiences.

For example, working with one particular event may be different from working with a broader pattern that developed across many experiences.

However, it is difficult to predict exactly how any individual target will unfold before you begin.

A memory that initially seems straightforward may connect with other material.

Another memory that seems significant may change relatively quickly.

For this reason, it is more useful to treat session numbers as flexible rather than trying to predict exactly how many sessions a target will require.

What If You Feel Much Better After One Session?

If the target feels substantially different after one session, you can notice that change without assuming you have to continue working with it immediately.

You may decide that you are satisfied with where the target is.

You may also want to see how it feels when you encounter related thoughts or situations in ordinary life.

If there are other targets you want to address, you can work with those separately.

There is no requirement to keep repeating the same target simply because you expected EMDR to take longer.

More sessions are not automatically better.

What If the Target Still Feels the Same?

Sometimes you may finish one session without noticing a major change.

That does not tell you exactly what will happen in a future session.

EMDR can unfold differently from one session to another, and not every session produces an obvious immediate shift.

You may decide that you want to return to the same target another time.

You may also reconsider how you are defining the target or notice that another related memory seems more relevant.

The important point is that one session does not have to produce a dramatic result in order for you to decide whether you want to continue.

Does a Strong Reaction Mean One Session Was Enough?

Not necessarily.

The intensity of your reaction is not a simple measure of how much progress occurred.

Crying, feeling emotional, feeling tired, or having another noticeable response does not automatically mean that the target has been completely processed.

Likewise, having a calm session does not mean that nothing happened.

You do not need a dramatic reaction for an EMDR session to be meaningful.

A better way to think about whether you want another session is to consider how the target itself feels and whether there is still something you want to work on.

Does a Longer Session Reduce the Number of Sessions You Need?

Not necessarily.

A longer EMDR session does not automatically replace several shorter sessions.

Adding more minutes to a session does not guarantee that a target will be completed faster.

Sometimes you may want more time with a target. At other times, a shorter session may be enough for what you want to do that day.

There is no need to make one session unusually long in an attempt to avoid doing another session.

You can stop when you have done enough and return another time if needed.

Is More EMDR Always Better?

No.

More EMDR is not automatically better simply because it means more sessions.

If you have already reached the point you wanted to reach with a particular target, there is no need to continue working with it just to add another session.

Likewise, if you have more you want to address, there is no need to treat needing another session as a problem.

The useful number of sessions is the number that fits what you are working on.

This may be different for different targets.

Can You Return to a Target Later?

Yes.

You do not have to make a permanent decision about a target when one session ends.

You might finish a session feeling satisfied with where you stopped and later realize that you want to return to the same memory.

You can.

You may also find that the original target no longer feels especially important but that another related issue now stands out.

EMDR can be flexible in this way.

A session does not have to resolve every possible part of an experience before you move on.

What If You Have Several Things You Want to Work On?

One EMDR session may focus mainly on one target, while you still have other targets you want to address.

For example, you may have several memories connected to a difficult period of your life.

Working with one of those memories does not necessarily address every other memory automatically.

You can decide which targets still feel relevant and work with them separately.

This is another reason it can be misleading to ask whether a certain number of sessions is “enough” without considering what you are trying to accomplish.

Some people may also have several memories or beliefs connected to self-esteem that they prefer to work on as separate targets.

One session may be enough for one target but not for everything you want to work on.

How Many EMDR Sessions Do People Usually Need?

There is no single number that applies to everyone.

Traditional therapist-guided EMDR is generally delivered across multiple sessions, but the total number can vary depending on what is being addressed and how the person responds.

A more focused concern may take fewer sessions than a broader history involving several related experiences.

However, averages cannot tell you exactly how many sessions a particular target will take.

For self-guided EMDR, there is also no established number of sessions that everyone needs to complete.

Rather than trying to reach a predetermined session count, you can consider what you want to work on and whether there is more you want to address after each session.

Do You Need to Decide on a Number of Sessions Before Starting?

No.

You do not have to decide, “I am going to do five sessions,” or “I am going to finish this in one session.”

You can begin with the target you want to work on and see how the process unfolds.

Afterward, you can decide what makes sense next.

That might mean returning to the same target, choosing another target, or deciding that you do not currently have anything else you want to address.

This keeps the focus on the work itself rather than on reaching a predetermined number.

One Session With Virtual EMDR

Virtual EMDR is a specific self-guided online EMDR program. This is different from the general phrase “virtual EMDR,” which may also be used to describe therapist-guided EMDR conducted remotely through video.

With Virtual EMDR, you decide when to do a session and manage your own pacing.

You do not need to decide in advance exactly how many sessions a particular target will require.

After a session, you can consider whether you want to return to the same target, work with something different, or stop there for now.

Because the format is self-guided, you can make that decision based on what remains relevant to you rather than on a predetermined number of appointments.

Conclusion

One EMDR session may be enough to make meaningful progress with a particular target, but there is no set number of sessions that works for everyone.

Some targets may change noticeably during one session. Others may take several sessions or lead to other memories, thoughts, emotions, or beliefs that you want to work with separately.

You do not have to completely process a target in one sitting, and you do not need to keep doing sessions simply to reach a particular number.

A stronger reaction, a longer session, or more sessions does not automatically mean more progress.

Instead, you can pay attention to how the target feels and whether there is still something you want to work on.

With self-guided EMDR, you can return to the same target another time, choose a different one, or decide that you have done enough for now.

Frequently Asked Questions

Can EMDR work after just one session? +
Some people may notice meaningful changes in a particular target during one EMDR session. However, one session will not necessarily be enough for every target or every person.
How many EMDR sessions do you usually need? +
There is no universal number. Therapist-guided EMDR is generally delivered across multiple sessions, but the total can vary considerably depending on what someone is working on and how the process unfolds.
Can one EMDR session completely process a memory? +
It may happen with some targets, but it cannot be expected for every memory. Some targets may take more than one session.
What if I still feel bothered by the target after one session? +
You can return to the same target in another session if you want to continue working with it. A target does not have to be completely resolved in one sitting.
Do I need another session if I feel better after the first one? +
Not necessarily. If you feel satisfied with where the target is, you do not need another session simply to increase the number of sessions you have completed.
Are more EMDR sessions always better? +
No. More sessions are not automatically better. The useful number depends on what you want to work on and whether there is still something you want to address.
Can I work on a different target in my next EMDR session? +
Yes. You may return to the same target or choose another one depending on what feels most relevant to you.
Does a strong emotional reaction mean the session worked? +
Not necessarily. The strength of an emotional reaction is not a simple measure of EMDR effectiveness. A session does not need to feel dramatic to be meaningful.
Should I make my first EMDR session longer so I can finish in one session? +
Not necessarily. A longer session does not guarantee that you will complete a target in one sitting. You can stop at a reasonable point and return to the target another time.
