Response prevention – OCD
Response prevention is a cognitive-behavioral therapy method used for obsessive-compulsive disorder. This module takes place after the five psychotherapy sessions preceding exposure to virtual reality, and is intended for patients suffering from OCD.

Key takeaways
- Response prevention is a CBT module for OCD, applied after exposure sessions in virtual reality.
- Practitioners list every ritual (behavioral or thought-related) before starting modifications.
- Rituals are reduced gradually by adjusting frequency, duration and delay before the act.
- Removing associated elements (e.g. changing soap brand) helps extinguish the ritual.
- Impulse phobia is intrusive-thought OCD, not a true phobia.
THE BEGINNING OF THE RITUALS
Patients with OCD need rituals (hand washing, cup counting). The exposure therapy you do with your patient afterwards will get them to stop doing their rituals. You can't ask a patient to stop doing them, it's too abrupt and will traumatize the patient. You have to do things slowly and gradually so that they can decrease them as they go along. To do this, you will have to touch several parameters of these rituals. This means that you need to be aware of your patients' practices. For example: How long do they last? What triggers them? What do you use?
The first thing to do with your patient is to list the situations in which they occur. Structure it in a way that answers the questions: When? How? With whom? How long? You can also give him a sheet of paper with about 50 empty boxes so that he can count them. Beforehand, you should list all the situations and rituals, whether they are behavioral (checking the locks, cleaning) or thought-related (counting). Once all the key situations and rituals are outlined, you can begin to modify them with the patient. On the basis of the parameters mentioned, you will progressively modify each of the parameters which will lead to a cessation of this ritual after several months, or even after a year.
THE FREQUENCY OF THE RITUAL
The first parameter to change is the frequency of the ritual. If the patient washes their hands 50 times a day, you can reduce that to 45 times. To change it, patients have to be committed and have to be able to do it. The goal is that they can actually change that frequency in that ritual. Ask, "If we go from 60 times a day to 45 times a day, can you do it?" Once the commitment is made, you can give her another chart with the ground rules. (I must change my rituals, I must follow my therapies, I must apply my therapies). The other parameter on which we can play is the duration of the ritual, if your patient washes his hands for 5 min, you can propose to him to wash them only 4 min 30.
TRIGGERING THE RITUAL
Another factor to consider is the delay in initiating the ritual. For example, tell your patients that when they are anxious and wash their hands, it is possible for them not to wash their hands right away, but to wait 30 seconds. In the meantime, suggest that they do some meditation, some relaxation methods, repeat slogans, mental imagery seen in previous therapies.
REMOVAL OF THE ELEMENTS
It is also possible to play on the removal of certain elements associated with rituals. For example: the use of a specific brand of soap to wash the hands. Suggest that they change the brand of soap. In the example seen throughout this article, the patient who is going to wash his hands 50 times a day will no longer wash 50 times but 40 times and not 5 min but 4 min 30, so he will be delayed by 30 seconds and will not wash with the same soap. All these modifications, associated with the ritual, will be noted on the patient's chart so that he/she will remember them.
The parameters will be modified progressively by playing on the frequency and duration until the ritual is completely extinguished. If unfortunately the patient has not been able to follow the modifications of all these parameters, propose only one or two.

THE IMPULSE PHOBIA
Let's talk in this last part about impulse phobia. This is a false friend, it's not a phobia but an impulse OCD. These are patients who will say: instead of falling down, I'm going to throw myself, or I'm going to strangle my husband, I'm going to kick the grandmother's poodle. Everyone has this kind of thought, most people just don't pay attention. In impulse phobia, patients will stay focused on these thoughts. By trying to stay in control and trying not to think about it, they will reinforce these thoughts and they will keep coming back. Having crazy thoughts is a normal phenomenon, it is the process of brain function. It is normal to have violent, blasphemous, transgressive thoughts. In the impulse toc, there is no acting out because the patient is afraid of acting out.

Frequently asked questions about response prevention in OCD and virtual reality
What is response prevention in OCD?
It is a cognitive behavioural therapy method for patients with obsessive-compulsive disorder. It is introduced after five psychotherapy sessions preceding virtual reality exposure and aims to gradually reduce rituals.
Can patients be asked to stop their rituals immediately?
No. Stopping abruptly can be too distressing and may be traumatic for the patient. The practitioner should gradually modify the parameters of the ritual, such as its frequency, duration and triggers, over several months or even a year.
How can the frequency of a ritual be reduced?
The practitioner gradually reduces the number of repetitions, for example from 50 to 45 times per day. The patient should commit to this reduction and confirm that they can maintain it before moving on to the next stage.
How can the start of a ritual be delayed?
The practitioner may ask the patient to wait, for example 30 seconds, before performing the ritual. During this delay, relaxation techniques, coping statements or mental imagery learned during previous therapy sessions can be used.
What is harm OCD?
It is not a phobia but a form of OCD involving intrusive thoughts. The patient remains focused on unwanted thoughts, which may be violent or transgressive, without acting on them, despite the anxiety-driven fear that they might.
Can I feel nauseous when using a virtual reality headset?
Yes, this can happen. This phenomenon is known as cybersickness and affects part of the population. It is reversible. It is recommended to begin with static environments before gradually introducing movement.
What is the role of the AI assistant Camille in this module?
The AI assistant Camille supports the patient without judgment during exposure sessions and provides a trusted source of support where they can share their concerns. The virtual characters in the scenarios reproduce realistic social behaviours.
What should I do if I have a problem with the headset or software?
