OCD is no longer classified as an anxiety disorder, nevertheless anxiety is a primary component of the disorder. Disgust and guilt are other emotions that may be experienced. Severe distress is accompanied by a cycle of obsessions and compulsions that characterize OCD.
Many people can relate to superstitious beliefs or to being "obsessive" about cleanliness or safety, but OCD is when these beliefs and behaviors begin to interfere with one's life in that it takes up more than an hour each day, causes a significant amount of distress, and impairs functioning in relationships, at school, at work, or in daily life.
Obsessions are intrusive, unwanted thoughts, images, or impulses that trigger intense distress. Obsessions are not the same as everyday worries in that oftentimes obsessions have little or no basis in terms of realistic probabilities of harm. Common obsessions include:
Compulsions are routines or rituals that are meant to prevent or reduce the distress that comes from the obsessions, and unlike gambling or drinking, compulsions are not experienced as pleasurable but rather torturous and time consuming. Common compulsions include:
The Obsessive Concerns Checklist provides a thorough list of common obsessions while the Compulsive Activities Checklist provides a thorough list of common compulsions.
The Yale-Brown Obsessive Compulsive Scale is also a list of common obsessions and compulsions along with questions to assess the severity of symptoms.
These measures are not meant to diagnose OCD but can give an understanding of the typical thoughts and behaviors that may be causing distress.
UNWANTED, INTRUSIVE THOUGHTS
The obsessions listed on the Obsessive Concerns Checklist are not specific to those with OCD, and in fact, studies have shown that most people in the general population acknowledge having had similar unwanted, intrusive thoughts at some point in their lives. The question then is, what might be the difference between those who develop OCD and those who do? The answer may be a combination of a highly active thought generating system, hyperawareness of dangerous thoughts, and a highly sensitive alarm system, all described below.
An explanation for why we have these spontaneous thoughts is that our brains are equipped with an ability to generate new ideas, which enables us as humans to create art, produce original solutions, or invent something new. It comes from systems in the brain that act collectively as a “thought generator.”
Some of these thoughts may be truly original ideas or they could be random connections to something we had heard, seen, or imagined. Sometimes thoughts may pop up just because there is a part of us that believes we should NOT think these thoughts, especially if they are thought to be scary, immoral, or socially inappropriate.
The OCD Spotlight:
Findings have shown over and over that there are few differences between those with OCD and those without regarding the content of unwanted, intrusive thoughts. In other words, the content of the thought generator described above appears to be similar in those who suffer from OCD and those who do not..
A difference though is that for those who do not suffer from OCD, unwanted, intrusive thoughts are usually evaluated as merely strange or perhaps disturbing, but no matter how repulsive or horrific the thoughts may be, they are experienced as just thoughts and thus not particularly problematic.
The thoughts may come uninvited, but for the most part, these fringe thoughts have to be accessed purposefully such as for a creative writing project or when recalling a horror movie. Either way, these thoughts are usually not processed any further and are quickly forgotten.
For those who struggle with OCD, these same thoughts present as loud, intense, and persistent making them difficult to ignore. It is as if the thoughts are being lit up by a bright spotlight. It is important to recognize that the intensity of the thought does not necessarily make the thought more important, just as the loudness of a voice does not necessarily make a message more meaningful nor does the size of a font make a message more real, though they do make the messages incredibly difficult to ignore.
Danger detection system:
Threatening thoughts that are brightly lit are more likely to be interpreted by the parts of our brains dedicated to self-preservation. This “danger detection system” is designed to anticipate, notice, and react to danger in a way to protect us from harm. Anxiety is part of this danger detection system.
An important part of our brains that is involved in the “danger detection system” and the experience of anxiety is the amygdala. The amygdala is part of our primitive brains and is involved in triggering the "fight or flight" response that is meant to protect us from danger. It is adaptive. It is protective. It is instinctual.
When the amygdala triggers the fight or flight response, there is an immediate whoosh of anxiety that is meant to propel us towards safety. This initial whoosh of anxiety, or primary anxiety response, is automatic, reflexive, conditioned, habitual, unconscious...it is outside of our conscious control. Furthermore, once the fight or flight response has been initiated, it takes time for the effects to dissipate, perhaps because it is adaptive for our bodies and brains to have a system that stays alert in case danger returns.
See the section on Understanding Anxiety and Anxiety and the Brain for a more thorough description of the fight or flight response and of the neurological explanations of anxiety.
The amygdala learns through experience that certain thoughts trigger an anxious fight or flight response, and each time this pairing occurs, the connection between thought and fear response becomes stronger and more intense. A saying is, "Neurons that fire together, wire together," meaning that the pathway between certain thoughts and the fear response becomes tread in so deeply that eventually a thought can automatically and rapidly trigger an intense physiological response - that initial whoosh of anxiety.
For those with OCD, the danger detection system may be very sensitively wired so that it readily detects any sign of potential danger, noticing signs that those without OCD may miss. The alarm that gets triggered may also be loud, intense, and frightening like you might imagine happening in a bomb shelter. On the other hand, those without OCD may hear an alarm similar to a smoke alarm, which generates fear and movement towards safety but is not nearly as overwhelming and challenging.
In summary, for those who suffer from OCD, the “thought generator” may be highly active, the “spotlight” may be brightly lit, and the “danger detection system” may be very sensitive so that these systems interact and react as if their lives are in imminent danger. These systems may be related to inheritable traits in brain chemistry or brain circuitry that are made even more sensitive by stress, fatigue, illness, or excessive drinking or marijuana use.
IIMPORTANCE PLACED ON THOUGHTS/COGNITIVE APPRAISALS
As mentioned above, the initial thought, the loudness of that thought, and the initial whoosh of anxiety, are outside of conscious control. These reactions are automatic. They are reflexive. They are conditioned. With OCD, though, there is another series of thoughts that occur in response to the initial thoughts and the initial whoosh of anxiety and add another layer of fear that can turn anxiety into terror.
These thoughts appraise the initial thoughts and initial anxiety as - Dangerous! Important! Bad! Disgusting! Immoral! Urgent! and also says, I need to be 100% certain there is no danger! I need to control this! I can't handle this! I have to get rid of this!
These thoughts are believed to occur in the cortex, or the "thinking brain," and have the potential to amplify the amygdala's alarm system, which adds fuel to the fire and creates a second more powerful surge of anxiety. This is secondary anxiety.
The more importance that is placed on the thought and on controlling the anxiety, the greater the distress and the more likely the obsession. Therefore, it is not surprising that harm obsessions often occur with gentle people, sexual obsessions occur with highly moral people, religious obsessions occur with religious people, and obsessions with mistakes occur with perfectionistic people.
The goal of therapy is to engage the cortex in a way that allows for more flexibility in thinking. This might look like, "OCD is making these thoughts seem really scary and seem really likely and is making me feel strong urges to do something about it, but I am choosing to take the risk, to tolerate uncertainty and to sit with discomfort, because I do not want OCD to control my life. I am choosing anxiety in the short term for freedom in the long."
The goal of therapy is not to provide reassurance that these thoughts are not true or that nothing bad will happen. The goal is to learn to learn to tolerate uncertainty and doubt and to learn to tolerate the discomfort that comes with this so that one can begin to say,
This does not get rid of the anxiety, as the initial whoosh of anxiety has already been triggered. Instead, this helps to minimize the second surge of intense anxiety so that the urge to engage in a compulsion is decreased to a manageable level.
There appear to be common themes underlying these appraisals in those who suffer from OCD. These beliefs tend to be rigid and absolute and contribute to the development and maintenance of OCD. These beliefs can be categorized as:
The Obsessional Beliefs Questionnaire is used to assess common beliefs about thoughts in those who suffer from OCD.
Scoring for the Obsessional Beliefs Questionnaire is here.
Once these beliefs are identified, they become easier to recognize when they are happening. They also become signs that it is likely OCD at work, and that it is discomfort and doubt, not danger.
COPING STRATEGIES in OCD
When importance is attached to the presence of a thought or the content of the thought, then the thought is experienced as dangerous, disgusting, or unbearable. The fight or flight response may also be triggered.
The natural protective response to these distressing emotions and feelings is a desire to get rid of the thought, control the thought, or put the fear to rest in some way.
Thought suppression, neutralization strategies, and avoidance behaviors are the most common coping strategies that contribute to the cycle of obsessive thoughts and compulsive behaviors.
In the beginning, these coping behaviors lead to a decrease in distress, and because there is some relief, these behaviors become reinforced and are more likely to occur the next time the distressing thought or feelings are experienced.
Eventually these behaviors become habits that feel automatic and uncontrollable. Unfortunately, in the long run, attempts to suppress, neutralize, or avoid the thoughts or feelings of fear:
An increase in thoughts and fear likely occur because the efforts put into getting rid of or avoiding the thought or situation tells the brain that these thoughts or situations are important, meaningful, and dangerous.
The brain then becomes fearful and alert, making it more likely for the thoughts to return, for baselines levels of anxiety to be higher, and for the anxious response to be greater. This then strengthens the feeling that these thoughts need to be controlled.
Because avoidant strategies do not directly address the source of the problem (the OCD), the cycle continues to spiral out of control creating additional problems.
Ultimately, the obsession and the anxiety are not the greatest problem, but rather it is the desire to avoid anxious feelings completely that becomes the biggest hurdle to living a full and meaningful life.
THOUGHT SUPPRESSION: The Paradoxical Effect
One common reaction to this surge of anxiety that accompanies the obsessive thought is to try to NOT think of the thought. The problem with this strategy is that there is a paradoxical effect where the more you try NOT to think of a thought, the more the thought will come to mind.
For example, if you were asked to close your eyes and try to think of polar bears for 2 minutes, you will find that various thoughts and images of polar bears cross through your mind, sometimes disappearing and reappearing outside of your control.
Now, if you try to NOT think of polar bears for the next 2 minutes, you will find that your thoughts are interrupted by thoughts or images of polar bears. If you were asked to do it for 20 minutes and pay $100 each time the thought or image occurred, the stakes become higher, and the task becomes impossible at worst, exhausting at best.
The reality is that we have little mental control over the thoughts that come into our mind and the more we attempt to control it, the worse the problem becomes.
NEUTRALIZATION STRATEGIES: Compulsions
Compulsions are external behaviors or mental rituals that are also attempts to neutralize, avoid, or remove the distress caused by the obsessions. Because compulsions do provide some immediate relief, the behaviors become reinforced, meaning they are more likely to happen again in the future in response to distress.
The problem with compulsions is that because of the polar bear effect described above, any attempts to remove or suppress the thoughts strengthens the importance placed on the thoughts making the thoughts more likely to return. This strategy, which seemed logical at first, becomes part of the problem.
Unfortunately, the relief provided by engaging in compulsions is often temporary and partial. The anxiety does not quite return to baseline, and when the thoughts returns, anxiety often returns with greater intensity. It is as if engaging in compulsions, confirms to the brain that the obsessions are dangerous or important and must be taken very seriously and with immediate action.
Another consequence is that compulsions, which are essentially responses to false alarms, do not allow the brain to learn that the thoughts or situations are not as dangerous as they seem and do not require immediate attention and also that the anxiety will eventually decrease all on its own and can be managed.
On the other hand, if there is no avoidance, there is no partial decrease in anxiety, but there is a natural habituation curve where the anxiety first increases rapidly, plateaus, and then slowly decreases. This is the natural curve of the anxious response.
With neutralization, there is never a chance to learn that the anxiety will decrease all on its own and that the feared consequence does not happen.
Another common coping strategy for dealing with fear is avoidance. Avoidance can include a wide variety of triggers such as situations, people, objects, information, physical sensations, emotional states, or thoughts.
The problem is that efforts to avoid the trigger places greater importance on the thoughts that are being avoided. In addition, with avoidance, there is no learning that the thoughts are thoughts that you can learn to handle and that the anxiety will decrease eventually on its own.
Also, avoidance leads to constant scanning of the environment for any other triggers. The list of triggers to detect and avoid grows longer and life becomes more restrictive.
Another common coping strategy in OCD is reassurance seeking. Like the other strategies discussed, reassurance seeking often lowers anxiety only temporarily but enough that the urge for reassurance gets stronger each time around.
Reassurance is often specific to a time and situation and thus any changes to the situation or any small doubt about the reassurance or the source of reassurance will require another round of reassurance seeking.
The problem is that the reassurance that is being sought is 100% certainty regarding a situation, and because this is not possible, there is a continuous need for reassurance.
Reassurance seeking can include asking someone about the obsession, researching the obsession, confessing to try to get reassurance, and self-reassurance such as mentally reviewing actions for reassurance that nothing bad happened.
Like the other avoidant strategies, reassurance seeking increases the importance placed on the thought because of the attention given to the thought which then makes the thought more likely to occur.
Usually the need for reassurance increases over time where each new doubt requires reassurance and any answers that are given only generates more doubts.
As with the other strategies discussed, reassurance seeking does not allow learning to occur that the fears are not likely and that the anxiety will decrease on its own.
Trigger....Thoughts(Obsessions)....Initial Anxiety....Interpretation...Anxiety Surge....Compulsions....Anxiety Relief....Obsessions (repeat)
The development and maintenance of OCD is believed to occur as follows: a thought occurs (with or without a trigger), an initial whoosh of anxiety occurs, the thoughts and the associated anxiety are interpreted as dangerous, important, urgent, or bad, and is accompanied by a demand for 100% certainty and control, which then leads to a second more intense surge of anxiety, which leads to frantic efforts to remove the distress (compulsions), which then makes it more likely for the thoughts to reoccur and become obsessions.
With each cycle, the frequency and intensity of the thoughts increase, which leads to more catastrophic interpretations, which leads to higher levels of anxiety, and which leads to more rigorous use of compulsions. This is the way in which the obsessive compulsive cycle can become debilitating.
The parts of this model that are NOT under voluntary control are the obsessions and the surges of anxiety. These aspects are involuntary in that spontaneous or disturbing thoughts can occur with all people and a surge of anxiety is a normal reaction to the perception of danger.
The parts that are potentially under voluntary control are the importance placed on the thoughts and the strategies used to deal with the distress (the interpretations and the compulsions). In the beginning, it may seem as if these components are also outside of voluntary control but it is just that they have become highly automatic.
Shifting out of thoughts and behaviors that have become automatic takes time and effort but eventually can be replaced by a new, automatic way of dealing with obsessions.
TREATING THE OCD BRAIN
There is a significant amount of information that suggests that OCD is a brain-related disorder that makes it difficult for the mind to let go of thoughts or urges. Dysfunction in certain brain structures (orbitofrontal cortex, basal ganglia) and brain systems (cingulo-opercular network) have been implicated in the development of OCD.
These brain structures and systems are thought to be responsible for generating normal impulses and urges with a built-in brake mechanism to stop these thoughts and urges. In OCD, it seems that the brain is overactive in generating thoughts, images, and impulses, and furthermore, like an itch that won't go away, the mechanism that tells us, "Your hands are clean, you can stop washing," or "The stove is turned off you can go to work now," does not function properly and does not get triggered.
Some people will ask, "If OCD is a brain-related disorder, then is medication the only treatment?" The answer is a pretty solid, "No." Studies have consistently found that cognitive-behavioral therapy can lead to significant reductions in OCD-related symptoms, similar to improvements with medications. More compelling is the evidence through brain scans that show that improvements with cognitive-behavioral therapy lead to similar brain changes as improvements with medications.
Psychotherapy can teach you new ways of approaching OCD while medications can help facilitate that process, making it easier to interrupt and redirect OCD thoughts and tolerate the discomfort of change. Therapy can be seen as a tool to help you decide what thoughts and behaviors to "grow," while medications "fertilize" and promote this growth. Once new patterns are established, these changes can be long lasting, even when medications are discontinued.
Education: It is important to have a strong understanding of the model of OCD as described above. This information will be used to help understand obsessive thoughts and appraisals that lead to distress. A more realistic, less catastrophic explanation for the obsessions can help manage the distress related to the obsessions.
It is also important to understand the treatment rationale as aspects of treatment can be challenging and distressing, and understanding WHY these strategies are being used can help make these uncomfortable feelings more tolerable.
Self-monitoring: It is important to understand your own unique obsessions, appraisals, compulsions, and avoidance behaviors. Self-monitoring can help identify patterns in your distress and all this information will help develop a specific treatment plan.
Mindfulness: Analyzing, arguing with, judging, reassuring, or explaining the thoughts tend to entangle the mind with the obsessions by adding importance to the thoughts, which then strengthens the obsession. For this reason, standard cognitive therapy techniques of challenging the fear often fuel the obsessions and increase the anxiety. This is because the OCD is seeking reassurance and unfortunately thoughts cannot be proven with absolute certainty to be untrue or safe.
Mindfulness can be used to train the mind to not react immediately to the worrisome thoughts by pushing them away or by debating them and instead acknowledging them, recognizing them as OCD, and accepting them.
For example, learning to respond with, "I am having thoughts about being uncertainty and harm," is a much different experience than, "I didn't check the stove before I left. If I don't go back and check, the house will burn down and I'll be responsible."
Mindfulness can be seen as the opposite of thought suppression, avoidance, and neutralizing compulsions. Accepting the obsessions does not mean wanting them or enjoying them, but rather acknowledging that they exist in the present moment and sitting with them without adding to the pain and distress that is already a part of the experience. Mindfulness is used to train the mind to observe the distress and also patiently sit with the urge to engage in a compulsion.
Rather than engage with the content of the obsessions, the most effective cognitive therapy tools are to recognize that OCD related distortions in thinking may be occurring and without engaging with the content of the thoughts. Cognitive therapy techniques can also be used to guide thoughts away from the urge to engage in the compulsive response. Maladaptive beliefs can also be explored to see ways in which they may be contributing to the maintenance of OCD.
Exposure and response prevention (ERP):
The primary treatment approach for OCD is called Exposure and Response Prevention.
Exposure means approaching in a graduated and controlled manner thoughts, images, objects, or situations that trigger obsessions.
Response prevention refers to allowing the anxiety to naturally and slowly subside on its own rather than engaging in a compulsive response that only strengthens the OCD. Response prevention allows for learning how to tolerate feelings of discomfort and distress without engaging in compulsions.
The belief is that a moderate level of anxiety is necessary to turn on the anxiety system and prime it for change. By continuously triggering the obsession and the fear and not engaging in a compulsion, the brain eventually habituates to the obsession and builds up tolerance to the experience of discomfort and distress.
Exposures are thus opportunities to rewire the brain by teaching it that feared consequences do not necessarily occur and that the ability to cope is stronger than once believed.
ERP can be the most challenging component of therapy but it is often times the most effective. Trying to think differently about obsessions does not seem to be as effective as experiencing it for yourself. It seems as if the part of the brain that is responsible for the fear response learns best through experience.
To make the process more tolerable, education, self-monitoring, and cognitive techniques are used to prepare for ERP.
FINDING A THERAPIST
Many therapists claim to use cognitive behavioral therapy (CBT) but are in fact using aspects of CBT incorporated into their style of talk therapy. Other therapists may be familiar with the idea of Exposure and Response Prevention (ERP) in the treatment for OCD but may not be well-versed in the complicated nature of the disorder and its treatment.
For the most effective treatment, it is important to find a therapist who has training and experience specifically in ERP for OCD.
