What role does anxiety play in OCD?
Summary
Obsessive-compulsive disorder (OCD) and anxiety are closely related. In most cases, anxiety perpetuates obsessive-compulsive symptoms , reinforcing the maladaptive relationship between obsessions and compulsions. In fact, historically, OCD was classified as an anxiety disorder and only in more recent diagnostic classifications was it defined as a distinct disorder.
What is the relationship between OCD and anxiety? Why is there a reinforcing cycle between them? What treatment options exist in these cases? What coping strategies can people with OCD and anxiety, and their families, use?
Relationship between OCD and anxiety
OCD is characterized by the presence of obsessions, which can manifest as intrusive thoughts and images or unwanted impulses. These obsessions are associated with a significant increase in suffering, distress, and guilt, which in most cases translate into anxiety.
Anxiety manifests through a wide variety of symptoms. Among the cognitive or mental symptoms are:
- Difficulty concentrating.
- Feeling of loss of control.
- Insomnia.
- Irritability.
- Perceptual disturbances (in more extreme cases).
Physical symptoms are also common, such as:
- Alteration of bowel movement pattern (frequency, consistency and ease with which a person evacuates their feces)
- Headaches.
- Stomach aches.
- Nonspecific neurological symptoms.
It is not uncommon for people, faced with these symptoms, to frequently consult medical services, without finding a physical cause to justify the somatic complaints.
How mindfulness can help manage OCD symptoms
On the other hand, OCD is characterized by compulsions, which consist of repetitive behaviors or mental rituals aimed at reducing the anxiety and discomfort caused by obsessions. Thus, the function of a compulsion is to prevent or temporarily reduce the anxiety generated by the obsession . However, the repetitive behaviors or mental repetitions that make up compulsions are, in most cases, not realistically related to what they intend to neutralize, avoid, or reduce, and are usually excessive and disproportionate. Furthermore, compulsions only relieve anxiety for a short period; when the obsessive thought reappears, the cycle restarts, progressively reinforcing the disorder.
A clear example would be a person with checking obsessions, one of whose obsessions is the possibility of having left their front door open. This person will experience anxiety every time they leave the house and will check again if they have left the door open. This checking becomes a compulsion when they need to do it repeatedly (checking if they have locked the door up to 10 times or more) and when it affects their functioning, for example, by causing them to be repeatedly late for appointments or even to the point of being unable to leave the house due to the perceived anxiety.
Compulsions relieve anxiety only for a short period of time; when the obsessive thought reappears, the cycle restarts, progressively reinforcing the disorder.
Another common example is that of a child or adolescent with obsessions related to harm: they may have intrusive thoughts about hurting a family member without meaning to. To reduce the anxiety these thoughts cause, they may avoid being alone with that person or perform constant mental rituals to "make sure" nothing will happen.
In some cases, compulsions take the form of rigid rituals or seemingly strange behaviors that the people themselves cannot clearly explain.
By definition, obsessions and compulsions in OCD are described as ego-dystonic , meaning the individual recognizes their obsessive thoughts as unpleasant, alien to their own thoughts, and uncontrollable. Although compulsions are performed to alleviate the distress caused by the obsessions, the person is often critical of them and perceives them as exaggerated or absurd. However, in childhood and adolescence, OCD symptoms may not be perceived as ego-dystonic; that is, individuals may not question their thoughts as much or perceive them as strange, which can sometimes complicate both diagnosis and therapeutic intervention.
Managing anxiety, a part of the treatment
The primary treatment for OCD is cognitive behavioral therapy , specifically exposure and response prevention therapy . In this therapy, individuals confront their obsessions, learning to manage the anxiety they provoke without performing the compulsions, thereby breaking the cycle of negative reinforcement that perpetuates OCD symptoms.
The treatment is structured and always guided by a qualified psychologist. Initially, a hierarchy of obsessions is collaboratively developed to serve as a model for gradual exposure therapy. Obsessions are ranked from least to most anxiety-inducing, with the goal of starting with the easiest exposures and gradually increasing the intensity. During exposure therapy, it is important to allow individuals to become accustomed to or learn to tolerate the anxiety before moving on to more intense exposures. By confronting their obsessions, they learn that the feared consequences are unlikely to occur and experience a gradual decrease in anxiety naturally, without performing the compulsion. They then realize that it is not necessary to constantly resort to their compulsions.
Anxiety and OCD are closely related, as it is one of the main protagonists of the negative reinforcement cycle that maintains obsessions and compulsions.
For example, in the case of a person with contamination obsessions and cleaning compulsions, a list is created, ranking situations from least to most anxiety-inducing (from touching seemingly clean spaces to touching spaces considered highly contaminated, such as a garbage container or using public transportation). The initial, less stressful exposures can even be done through imagery or imagination, gradually progressing to in vivo exposures as the person learns to tolerate the anxiety and is able to refrain from performing the compulsion to alleviate the discomfort.
In moderate to severe cases of OCD, medication is indicated as an adjunct to cognitive behavioral therapy. Specifically, selective serotonin reuptake inhibitors (SSRIs) are considered the first-line medication for OCD. In most cases, higher doses than those used for other disorders are necessary to achieve an adequate clinical response, always under medical supervision.

Recommendations for families
Based on the information provided, we highlight below some key aspects that families should keep in mind:
- Anxiety is a component of OCD . Anxiety and OCD are closely related, with anxiety being a key player in the negative reinforcement cycle that perpetuates obsessions and compulsions. Understanding this will help us understand certain behaviors of affected individuals, who often feel trapped in this obsession-compulsion cycle.
- Compulsions don't follow a realistic logic ; they are exaggerated and disproportionate. Maintaining an understanding and non-judgmental attitude within families will reduce conflict and make it easier for the person to talk openly about their symptoms.
- Helping to identify obsessions and externalizing OCD . Naming the problem as something external ("this is OCD, not you") helps the person cope with the symptoms in a more adaptive way and with a greater sense of control. This encourages them to develop confidence and resist giving in to obsessions and compulsions.
- Anxiety is also part of the treatment. Learning to tolerate it is key. For example, a child with a fear of contamination might be asked to touch a contaminated surface (e.g., a doorknob), to remain with the anxiety until they naturally become accustomed to it or learn to tolerate the distress, and eventually to refrain from the compulsion to wash their hands. Once the task has been repeated and mastered, exposures will progress to slightly more challenging tasks.
- The role of families is essential. Families participate in developing the exposure hierarchy and help keep exposures out of therapy sessions. They also receive psychoeducation to model appropriate coping strategies and create a cohesive family environment to combat OCD symptoms.
- Reducing family accommodation . Family involvement in therapy is especially important when there is significant accommodation of symptoms in daily routines. Adapting routines, facilitating rituals, or avoiding situations to reduce the affected person's discomfort, although well-intentioned, reinforces the symptoms of OCD. Identifying and gradually reducing these behaviors is key to interrupting the persistence of symptoms and improving the person's functioning.
- Caring for the family is also important . OCD can be very emotionally draining. Seeking support, resolving doubts with professionals, and validating the caregivers' own emotions are equally important.
- Surrounding yourself with a specialized professional team , including a psychologist and psychiatrist, is essential for an effective approach to OCD.
