Understanding Obsessive-Compulsive Disorder

Obsessive-Compulsive Disorder (OCD) is characterised by recurring intrusive thoughts, images, urges or doubts, alongside behaviours or mental acts performed to reduce distress, prevent a feared outcome, or achieve a sense that things feel complete or “just right”.

Compulsions are not always visible. They can include checking, reassurance seeking, washing or cleaning, repeating, arranging, reviewing memories, mentally checking, neutralising thoughts, or repeatedly trying to reach certainty.

Although compulsions can provide temporary relief, they can also reinforce the cycle by preventing the person from learning that uncertainty, discomfort or intrusive experiences can be tolerated without performing the usual response.

Exposure and Response Prevention (ERP)

Exposure and Response Prevention (ERP) is a behavioural intervention for OCD. It involves gradually approaching situations, thoughts, sensations or uncertainties that trigger obsessive-compulsive responses, while reducing or preventing the compulsions that would usually follow.

ERP is not simply about reducing anxiety or becoming accustomed to discomfort. The aim is to create opportunities to learn that intrusive thoughts, uncertainty and uncomfortable internal experiences can be experienced without needing to resolve, neutralise or control them through compulsive behaviour.

Exposure experiments are individually designed around the person’s particular fears, predictions and compulsive responses. This may involve working with overt behaviours, such as checking or washing, as well as less visible responses such as mental reviewing, reassurance seeking, rumination or attempts to achieve certainty.

Is ERP Right for Me?

ERP is individually formulated rather than delivered as a standardised set of exposure exercises. The specific approach depends on the experiences that trigger the obsessive-compulsive cycle, the responses that follow, and what those responses are intended to achieve.

For some people, the central difficulty is fear of a particular outcome. For others, it may involve uncertainty, responsibility, incompleteness, sensory discomfort or a need for things to feel “just right”. Compulsions may also be overt, largely mental, or intertwined with tic-like or repetitive behaviours.

Assessment is therefore used to understand the processes maintaining the difficulty and to determine how ERP should be structured for the individual.

How the OCD Cycle Is Maintained

OCD can be understood as a repeating cycle. An intrusive thought, image, urge, sensation or doubt triggers discomfort or a sense that something is wrong, incomplete or uncertain. The person then performs a compulsion or other response intended to resolve that experience.

Intrusion or trigger → discomfort / uncertainty → compulsion → temporary relief → cycle reinforced

The temporary relief that follows a compulsion can reinforce the response, making it more likely to occur again when a similar trigger appears. Over time, the person may become increasingly reliant on checking, avoidance, reassurance, mental reviewing or other strategies to restore a sense of safety or certainty.

Behavioural intervention aims to interrupt this cycle. Rather than repeatedly resolving the discomfort, ERP creates opportunities for the brain to learn that the experience can be tolerated and that the usual compulsive response is not necessary.

When OCD Involves Incompleteness or “Not Just Right” Experiences

Not all obsessive-compulsive experiences are primarily driven by fear or anxiety. Some people describe a powerful sense of incompleteness, internal tension, or a feeling that something is “not just right”.

This can lead to behaviours being repeated until they feel correct, symmetrical, complete or resolved. Examples can include rereading, rewriting, arranging, touching, repeating movements, restarting tasks or performing actions according to particular internal rules.

Assessment therefore considers what is driving the behaviour, rather than focusing only on what the behaviour looks like. Understanding whether a response is linked to fear, uncertainty, incompleteness, sensory discomfort or another internal experience can help determine how behavioural intervention is structured.

Complex OCD Presentations

OCD does not always present as obvious rituals or avoidance. Some compulsive responses can occur almost entirely internally, making the pattern more difficult to recognise.

These may include repeatedly reviewing memories, analysing thoughts, checking feelings, testing whether something feels true, mentally rehearsing events, seeking internal certainty, neutralising thoughts, or becoming caught in prolonged rumination.

OCD can also become intertwined with perfectionism, responsibility, morality, relationships, health concerns, identity or fears about losing control. The specific content can vary considerably, but the behavioural cycle may remain similar.

Intervention therefore focuses not only on the content of the obsession, but on identifying the responses that keep the cycle going and creating opportunities to respond differently.

When OCD and Tic Overlap

OCD and tic disorders can sometimes overlap in ways that make individual behaviours difficult to classify. A repetitive action may be influenced by an obsessive fear, a premonitory urge, a sense of incompleteness or “not just right” experience, or a combination of these.

Some people describe behaviours that have features of both tics and compulsions. For example, an action may need to be repeated until a particular sensation is relieved or until the movement feels complete, rather than being performed solely to prevent a feared consequence.

Careful assessment of the experience preceding the behaviour, what the person is trying to achieve by performing it, and what happens when they resist it can help clarify the pattern.

Where tic and obsessive-compulsive symptoms overlap, behavioural intervention can be individually formulated using elements of Exposure and Response Prevention (ERP) and Habit Reversal Training (HRT) where appropriate.

Assessment

Assessment focuses on developing a detailed understanding of the person’s obsessive-compulsive experiences and the processes that maintain them. This includes identifying intrusive thoughts, images, urges or doubts; overt and mental compulsions; avoidance; reassurance seeking; and the role of uncertainty, fear, sensory discomfort or incompleteness.

Where relevant, assessment also considers tic symptoms, premonitory urges and repetitive behaviours, particularly when it is unclear whether an experience is better understood as a tic, compulsion, or a combination of both.

Assessment can be completed in person in London or online. Following assessment, an individual formulation is used to determine whether ERP or another behavioural approach is appropriate and how the intervention should be individually structured.

About Dr. Patel

Dr. Dipesh Patel is a HCPC-registered Practitioner Psychologist with specialist experience in behavioural interventions for tic disorders and obsessive-compulsive symptoms.

He works within the Tourette Syndrome Service at the National Hospital for Neurology and Neurosurgery (NHNN) and is completing a PhD at the UCL Queen Square Institute of Neurology, investigating behavioural interventions for people experiencing co-occurring tic disorders and obsessive-compulsive symptoms.

His clinical approach draws on behavioural psychology and neuroscience, with a particular interest in understanding the relationship between urges, intrusive experiences, compulsions and repetitive behaviours, and using this understanding to develop individually formulated interventions.

Frequently Asked Questions

1. What is ERP for OCD?

ERP is an established behavioural intervention for OCD. It involves approaching situations, thoughts, sensations or uncertainties that trigger obsessive-compulsive responses while reducing the compulsions that would usually follow.

2. Do I need to have visible compulsions for ERP to be helpful?

No. Compulsions can be behavioural or mental. Mental reviewing, analysing, neutralising thoughts, checking feelings, seeking certainty and reassurance can all form part of an obsessive-compulsive cycle.

3. What if my OCD does not seem to be driven by anxiety?

OCD can also involve incompleteness, internal tension or “not just right” experiences. Assessment focuses on understanding what drives the repetitive response so that behavioural experiments can be designed around the individual pattern.

4. Can you work with OCD and tic disorders together?

Yes. When tics and obsessive-compulsive symptoms overlap, assessment considers the experiences and processes underlying each behaviour. Where appropriate, intervention can incorporate elements of both ERP and HRT.
