What to Expect in Your First Month of ERP Therapy

Starting therapy for OCD can bring up a mix of hope, anxiety, and uncertainty. Many people wonder what to expect in their first month of ERP therapy, especially if they have heard that ERP is challenging or intense. You may be asking yourself whether you will be pushed too quickly, how difficult ERP therapy really is, or how you will know if it is working for you.

The first month of ERP therapy is often misunderstood. Rather than jumping straight into the most distressing exposures, early ERP focuses on proper assessment of your OCD symptoms, learning how OCD operates, and building a foundation for meaningful change. This post walks through what happens in the first month of ERP therapy, addresses common fears about beginning treatment, and explains what early progress can look like. It is also important to normalize the fact that progress can look different for every individual. This post also outlines an alternative evidence-based option for OCD treatment for those who may find ERP is not the right fit.

What happens in the first month of ERP therapy?

The first month of ERP therapy is typically fairly structured and intentional. The goal is not to overwhelm you, but for your therapist and you to better understand your symptoms of OCD. This will properly inform treatment planning and allow for treatment goals to be clarified. Treatment will also begin to focus on understanding how you can change your relationship with intrusive thoughts and compulsions in a manageable way. This can allow you to see that change is possible and you can handle what comes your way during treatment.

Week 1: Assessment, hierarchy building, and psychoeducation

Early ERP sessions focus on understanding how OCD shows up for you specifically. This includes discussing your intrusive thoughts, compulsive behaviours, avoidance patterns, and reassurance seeking. You and your therapist work together to identify triggers and understand how attempts to reduce distress may be unintentionally maintaining symptoms.

Psychoeducation in ERP therapy is central during this phase. You will learn how OCD operates, why compulsions provide only temporary relief, and how response prevention may help to retrain the brain over time.

A key part of this phase is also ERP assessment and hierarchy building. There are different ways that an exposure hierarchy can be created between you and your therapist. A traditional type of exposure hierarchy will be a structured list of situations or triggers that provoke distress, ranked from less distressing to more challenging. This hierarchy helps guide treatment and ensures that exposure work progresses gradually rather than abruptly. 

There are other ways that an exposure hierarchy can be constructed. Your therapist can also create more of what Dr. Taube-Schiff calls an ERP roadmap. This allows you to think about items that might be less difficult, moderately difficult, and extremely difficult in a more levelled way. You can always jump around any type of graduated hierarchy in a way that is meaningful for you.

At Forward Thinking Psychological Services®, we also infuse a values-based approach into our ERP work. We will discuss which exposure work feels most meaningful to you so that you are not doing exposure work just for the sake of being distressed. But you are also able to see real value and life changes from what you choose to do.

Weeks 2–4: Starting exposures and learning response prevention

Once the foundation is in place, ERP therapy begins to introduce behavioural change. This typically involves starting exposures in ERP that are drawn from the lower end of your hierarchy or that you choose because they are very meaningful to you. Exposures are designed to help you experience distress or uncertainty without engaging in compulsions.

At the same time, you will begin learning response prevention, which involves resisting urges to perform rituals, seek reassurance, or avoid feared situations. This is often the most challenging part of ERP, but it is also the part that leads to lasting change.

There are different tools that can help individuals when learning response prevention. For example, learning cognitive strategies can help individuals to reappraise the thoughts that compel them to engage in rituals and this can be a powerful tool during ERP therapy. This speaks more to the idea of cognitive strategies in the context of ERP therapy. These tools can be woven into your ERP work. An advanced CBT therapist for OCD will be trained to do this with you in a manner that you find to be most helpful.

During these early weeks, the focus is not on eliminating distress and anxiety but on learning that distress, anxiety and uncertainty can be tolerated without compulsive action. Sessions often include review, problem-solving, and adjustments based on how exposures are experienced.

Is ERP therapy hard at first?

This is one of the most common questions we hear people ask our team when starting ERP therapy for OCD. The honest answer is that ERP can feel difficult at times, especially early on, but it is not meant to be overwhelming or punitive. In the long run, it is meant to give you your life back and allow you to do things that are meaningful to you. 

While anxiety may be part of the experience, OCD treatment focuses less on reducing anxiety and more on changing how intrusive thoughts and urges are responded to over time.

Common fears about beginning ERP therapy

Many people worry that ERP therapy will involve being forced to face their worst fears immediately or that they will be unable to cope with the distress. Others fear that their anxiety will spiral out of control or that they will fail if they struggle. 

Common concerns include:

• Is ERP therapy hard at first?
• Is ERP therapy overwhelming?
• What if I cannot tolerate the anxiety?
• What if ERP makes my symptoms worse?

These fears are understandable, particularly for individuals who have spent years trying to reduce or avoid anxiety. People will go to great lengths to avoid their triggers. And it is very understandable. Dr. Taube-Schiff will often say to the people she works with, “No one is saying sign me up to experience anxiety and distress, including myself!” However, that is not what we want to do when working with you. ERP is structured to move gradually and collaboratively, with ongoing support and adjustment. And there are different skills and tools we integrate into ERP therapy to ensure you are working at a pace that is manageable and bringing you closer to the life you want to lead.

How difficult is ERP therapy really?

ERP therapy challenges avoidance, rituals and compulsions, which can feel uncomfortable. These strategies are often used in response to intrusive thoughts or obsessional doubts. However, the difficulty when resisting compulsions or rituals may be less intense than anticipated. It is important to speak about this with your therapist. Early exposures are typically designed to be manageable and achievable, not extreme. Learning about distress tolerance skills and distress reappraisal is also an integral part of CBT-based ERP therapy. Your therapist will want you to feel equipped and supported to do the work that will bring you back to where you want to be. 

Importantly, we want you to remember that experiencing distress and difficulty does not at all mean that treatment is not working for you or that you are a “failure”. In fact, feeling some anxiety and distress is an expected part of the learning process that happens during ERP. And there is a lot of learning that does take place. In fact, there is the Inhibitory Learning Approach to Exposure and Response Prevention Therapy that speaks to the importance of learning that takes place during ERP. 

Traditional ERP relies on the idea of habituation, which means that our fears and doubts should “extinguish” when engaging in ERP. However, it does not always seem to be the case that people just unlearn things, although it might happen sometimes. Inhibitory Learning Theory posits that ERP actually teaches us new information about the safety of the situation. Therefore, following a successful exposure, a previous trigger would retain its original fear-based meaning (e.g., if the lock is open, someone will break in and harm my family) as well as the new safety meaning that was learned (e.g., I live in a safe neighbourhood and I can safely tolerate not checking to see whether I locked the door).

Overall, Inhibitory Learning Theory suggests that ERP should help people to learn this experience of safety in a manner that is strong enough to remove (or inhibit) the original fear that the person had. This is the underpinning of inhibitory learning. If your therapist is approaching ERP with this lens, you will learn skills to pay attention to the important learning that takes place during exposure work.

Over time, with ongoing exposure therapy, many people find that anxiety and distress become more predictable and less controlling, even if these emotions do not disappear entirely.

How will I know if ERP therapy is working early on?

People often expect progress to look like rapid symptom reduction. In reality, early signs ERP therapy is working are often more subtle and cognitive than behavioural. It is important to remember that listening to your OCD and acting on your compulsions may have become a well-worn pattern. And, of course, it is difficult to change well-worn patterns overnight. It takes time, learning and self-compassion to not judge yourself too harshly if things do not change right away.

You have done the hard work of searching for a therapist and starting the therapy journey. It is hard to do and it is important to feel proud of yourself for being brave and showing up to therapy, ready to learn and make changes over time. 

Early signs ERP therapy is working

Early progress may include:

• Increased awareness of compulsive urges before acting on them
• Shorter duration of compulsive behaviours
• Greater willingness to tolerate uncertainty or distress
• Reduced reliance on reassurance or avoidance
• Feeling less driven to “solve” intrusive thoughts or obsessional doubts immediately

These changes reflect shifts in how you respond to OCD rather than the absence of intrusive thoughts. And this is an important goal to keep in mind. Many people continue to experience intrusive thoughts (at times) and obsessional doubts occasionally. Our minds can throw a lot of thoughts our way. By doing ERP-based CBT, you are learning important skills to be able to manage these thoughts, respond to them differently and navigate your life in a way that works for you. 

What improvement looks like in the first month

During the first month, improvement often looks like increased flexibility rather than comfort. You may still feel distress at times or feelings of anxiety, but you may notice that the distress and anxiety feel less urgent or less convincing. You may also begin to recognize patterns more clearly and feel more confident applying skills outside of sessions.

ERP therapy is a process of learning, not a quick fix. Early progress sets the stage for bigger and more sustained change later in treatment. At Forward Thinking Psychological Services®, we talk about the ERP lifestyle. This means that you start to live your life by navigating organic, unplanned ERPs that come your way. In doing so, you will approach previous triggers differently and learn to resist compulsions naturally.

Is ERP the only treatment for OCD?

Exposure and Response Prevention (ERP) is often described as the gold-standard treatment for OCD, and for many people it can be highly effective. That said, ERP is not the only evidence-based treatment for OCD, and it is not the right fit for everyone. Presenting ERP as the sole option can unintentionally leave people feeling discouraged or stuck if exposure-based work feels overwhelming or inaccessible. Some individuals we see will say, “I don’t want to white-knuckle through ERP” or “ERP worked for me in the past, but my OCD symptoms have gotten worse and I would like to try another approach”.

OCD is a heterogeneous condition, meaning it does not operate the same way for everyone. Some individuals experience OCD primarily through overt behavioural compulsions and avoidance, while others are more impacted by persistent doubt, mental compulsions, and rumination. Because of this variability, different treatment approaches may be more or less helpful depending on how OCD shows up for a particular person. It is important to keep an open mind when your therapist is telling you about the different approaches. It can also be advantageous to go to a clinic where they offer different evidence-based approaches for OCD. This allows for you to have a choice for therapy and fully understand all your options. 

Alternatives to ERP for OCD

For individuals who struggle with the behavioural demands of ERP or who want to try an approach that does not involve exposure therapy, Inference-Based Cognitive Behavioural Therapy (I-CBT) offers an alternative evidence-based pathway. Inference-Based CBT (I-CBT) focuses on how obsessive doubts are constructed and maintained. Inferential confusion is a key concept and suggests that OCD focuses on reasoning processes that highlight imagined possibilities over those which we understand through our perceptual reasoning processes in the here and now.. 

When learning I-CBT for OCD, individuals learn skills to remain in the present moment of reality and not move into the imaginary narrative that their OCD has built for them. This is a very different approach and can be helpful for many individuals to be able to learn the what and the why of their OCD and how they can identify these faulty reasoning processes. 

Choosing an alternative approach to ERP does not mean avoiding treatment or taking a less effective approach. Especially because research has demonstrated that both therapeutic approaches are effective choices for symptoms of OCD. 

What it does mean is that you have been well educated about different ways that treatment can be effectively provided. And you have been able to think through what might be most helpful for you and your treatment preference at this moment in time. Exploring your options can also support your engagement, reduce the chances of dropout, and increase a sense of agency in the therapy process. These are all very important factors for your ability to succeed and remain engaged with your treatment providers. 

ERP vs inference-based CBT

As described, ERP focuses on changing behaviour by helping individuals face feared situations and resist compulsions. I-CBT, by contrast, focuses on how obsessive doubts are formed and maintained. Rather than emphasizing exposure, I-CBT works to dismantle the reasoning processes that lead people to step into their obsessional narrative and leave what they actually know to be true in the here and now of this moment. 

It is important to remember that both are evidence-based approaches. Therefore, the ability to choose between them will depend on different factors. As discussed, these may include treatments you have tried in the past, what approach resonated with you in this moment and what you feel most able and willing to jump into. It is wonderful that we have rigorous treatment options for OCD, and it is important to ensure that people can access them in a timely way. 

When ERP may not feel like the right fit

ERP may feel less suitable for individuals who:

• struggle primarily with mental compulsions and rumination
• feel overwhelmed by behavioural exposure
• are highly stuck in obsessive reasoning rather than avoidance

In these cases (and others), exploring alternatives to ERP for OCD can be an important part of informed treatment planning. See the table below for a comparison and ERP and I-CBT and how they operate early on in your OCD treatment process

Table: ERP and an I-CBT Approaches in Early OCD Treatment

How do I know which OCD treatment approach is right for me?

Deciding which treatment approach to pursue is not always straightforward, especially early on. Some people find the behavioural focus of ERP clear and motivating, while others feel more comfortable starting with an approach that targets obsessional doubt and obsessional reasoning processes. There is no single “correct” choice, and the best fit often depends on how OCD shows up for you, what feels manageable at this stage of treatment, and how ready you feel to engage with different types of therapy-related work. 

What matters most is that the approach is evidence-based and that you feel supported, informed, and actively involved in the process. For some individuals, ERP provides a clear behavioural treatment pathway forward and this allows people to feel that they are “doing something” right from the get go of their therapy engagement. For others, an alternative such as inference-based CBT may feel more accessible. And people may benefit from raising their awareness right away regarding faulty reasoning processes within OCD that are maintaining your symptoms. Overall, there is much to be gained from both approaches.

In many cases, treatment planning involves careful discussion, clarification, and adjustment over time rather than a one-time decision. Working with a clinician who is experienced in different types of evidence-based OCD treatments can help you understand your options and choose an approach that aligns with both your symptoms and your capacity, particularly during the early stages of therapy.

Conclusion

The first month of ERP therapy is often less about confronting extreme fears and more about learning how OCD operates and how change happens. Feeling anxious, uncertain, or hesitant early on is common and does not indicate failure. Early progress often shows up as greater awareness, increased flexibility, and a growing ability to tolerate uncertainty.

ERP is a well-supported treatment for OCD, but it is not the only option. Understanding what to expect and knowing that alternatives exist can help you make informed decisions about your care. As discussed in our post, Inference-Based CBT for OCD is another effective evidence-based approach that will also help you with your OCD symptoms.

If you are considering starting therapy or are unsure which approach is right for you, working with a clinician experienced in OCD treatment can help you navigate the next steps with clarity and confidence. If you’re considering therapy and feel unsure which approach is right for you, speaking with a clinician who specializes in OCD can help clarify your options. At Forward Thinking Psychological Services®, we offer online therapy so individuals, teens, couples, and families can explore treatment approaches and next steps in a way that feels accessible and manageable.
