Obsessive-compulsive disorder (OCD) is a condition typically depicted in popular media as one of behaviors rather than thought. In popular TV shows and movies, an individual with OCD may exhibit behaviors such as arranging items, tapping surfaces, and flipping light switches on and off. While these compulsions can be an accurate depiction of the condition, obsessive-compulsive disorder can be more complicated, often involving thought patterns that aren’t noticeable to others. 

Pure obsessional OCD is a form of OCD that involves obsessive thoughts without physical compulsions. While this type of OCD may be viewed as a less severe form, pure O OCD can be distressing and disruptive to daily life and is a valid form of OCD.

What is obsessive-compulsive disorder?

Obsessive-compulsive disorder is a mental health condition classified by intrusive and obsessive thoughts and ritualistic behaviors that are often used to relieve these thoughts. 

Causes of obsessive-compulsive disorder

Like many mental health conditions, scientists have not identified a single cause of obsessive-compulsive disorder. Rather, they hypothesize that an individual develops OCD as the outcome of several contributing genetic, environmental, and social factors. Some of these factors can include a family history of OCD or other mental disorders, the presence of certain personality traits, and experiencing traumatic events.

Experiencing OCD without the compulsions

Pure O OCD (also known as purely obsessional OCD or primarily obsessional OCD) is thought by some experts to be considered a misnomer. While a person with this disorder does not exhibit visible physical compulsions, they often do experience mental compulsions or mental rituals in response to their intrusive thoughts. These hidden mental rituals exist to “fix” the scary, wrong, or disturbing cycle of thoughts. 

Symptoms of pure O obsessive-compulsive disorder

Pure O OCD can be difficult to diagnose because it is not a clinical diagnosis in the latest edition of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). Instead, it falls under the general diagnosis of OCD. In addition, clients may be reluctant to share their symptoms, as these intrusive thoughts and mental compulsions are often embarrassing. Having a patient mental health practitioner and open-ended questioning may help encourage clients to discuss the symptoms of this disorder, which may include but aren’t limited to the following: 

  • Repetitive and distressing thoughts, images, or impulses
  • Continual and often exhausting attempts to neutralize these patterns of obsessive thought
  • Continually seeking reassurance from others
  • Mentally repeating specific words
  • Mentally re-doing certain actions
  • Avoiding stressful situations or people 

Because the symptoms of obsessive OCD are occurring in the individual’s mind, it can be challenging for others to know they’re happening. Friends and family members may perceive constant requests for reassurance as “neediness” and may not recognize them as symptoms of a mental health disorder.

Common pure O OCD obsessions and compulsions 

The intrusive and obsessive thoughts of an individual experiencing OCD can vary but typically fall into one of several common categories, including the following: 

  • Doubt about a romantic partner or relationship 
  • Disturbing or inappropriate sexual acts
  • Aggressive or violent ideas
  • Fear of something bad happening to a loved one
  • Sacrilegious thoughts
  • Tracking or worrying over somatic actions (breathing, swallowing, blinking)
  • Doing something embarrassing

In response to these repetitive and disruptive thoughts, an individual may try to find the answer behind them or “fix” them through the following mental compulsive behaviors:

  • Reassuring themselves about their motives and thoughts
  • Mentally reviewing memories, experiences, and ideas
  • Trying to neutralize thoughts through rationalization
  • Seeking reassurance from others
  • Avoiding situations that incite obsessive thoughts 
  • Performing superstitious rituals (mentally)
  • Continually questioning their own motives

How pure O OCD can impact mental health

Obsessive-compulsive disorder can be emotionally, mentally, and physically exhausting. Large amounts of energy are spent on obsessing over thoughts and in the rituals intended to fix those thoughts. Pure O OCD can be especially difficult to diagnose as symptoms can be more challenging to identify by oneself or by loved ones since it plays out in your head. Because these symptoms are not widely recognized, they can cause damage in relationships if loved ones become frustrated by the individual’s constant need for reassurance. 

Treatment options for obsessive-compulsive disorder

When it comes to treatment, pure obsessional OCD symptoms may be managed by a combination of psychotherapy, medication, and healthy lifestyle habits. 

Medications for OCD

Common medications prescribed for obsessive-compulsive disorder include selective serotonin reuptake inhibitors (SSRIs) and certain tricyclic antidepressants. In some cases, these medications may be augmented with second-generation antipsychotics.

Common therapies for OCD

Research indicates that specific psychotherapy approaches can be highly effective in treating Pure O, including cognitive-behavioral therapy (CBT), exposure and response prevention (ERP), and mindfulness-based cognitive behavioral therapy (MB-CBT). 

Self-care practices for mental health

Specific strategies that promote mental and physical health may be recommended to help manage symptoms of Pure O, including but not limited to the following: 

  • Getting regular physical activity
  • Practicing relaxation exercises such as meditation, progressive muscle relaxation, and deep breathing 
  • Maintaining strong social connections
  • Seeking community through OCD support groups

Therapy for obsessive-compulsive disorder

Talk therapy is one of the primary treatments for pure O and related disorders like anxiety. Some individuals choose not to take medication, and even when prescribed medication, therapy is recommended to address the obsessive thoughts and compulsions experienced with this disorder. Cognitive-behavioral therapy is the most common and effective form of therapy for pure O. In addition to treating symptoms, a licensed therapist can also provide stress management tools and teach coping strategies that reduce challenges and improve one’s overall quality of life.

Online treatment for OCD

For some individuals, scheduling in-person therapy appointments may be difficult or impossible. There may not be a licensed therapist available in their area who specializes in pure O, or they may find it emotionally taxing to meet with a therapist in person. Online therapy offers a convenient and effective solution to these challenges. 

Research has demonstrated that online therapy can be as effective as in-person therapy. With an online platform like BetterHelp, you can complete an online questionnaire to be matched with a licensed professional who meets your personal needs. Additionally, you can access resources such as weekly support groups and worksheets to support your mental health journey. 

Takeaway

While often considered a less severe form of OCD, pure O OCD can be extremely distressing and disrupt daily life and relationships. Symptoms are treatable, but it can be difficult for a person experiencing this disorder to share their mental experience with others due to embarrassment over their intrusive thoughts. Recognize that these thoughts are common in this form of disorder and therapy can often offer significant relief. If you suspect that intrusive thoughts may be related to pure O OCD, don’t hesitate to reach out to a professional in your area or an online platform to reduce symptoms and improve your overall mental health and wellness.
