The word “delusion” in obsessive-compulsive disorder explains the absence of insight, not fixed belief associated with psychosis. Insight and pathological doubt provide clues about how psychological treatment might work differently for each person on the obsessive-compulsive spectrum and show whether this treatment is likely to be useful or not.
How does a clinician assess insight?
This would usually be taken into account during assessment with the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS II). If not, any signs would typically be revealed during treatment. The same goes for pathological doubt.
First, intrusive thoughts or obsessions can be described as involuntary interruptions that get sandwiched between every-day regular thoughts. While intrusive thoughts interfere, they do not exist outside of a person’s awareness and do not convert to action. People who have good insight into their OCD know this, but have doubts about it.
So they still desire certainty, is that right?
Yes, doubt versus certainty plays a significant role in OCD. A person’s search for reassurance strengthens the obsession, so reinforcing this concept in therapy is a must.
Why else is this concept reinforced?
Some patients convince themselves their fear has or will come true, even though the emphasis is that emotional reasoning supports those assumptions. They find it hard to grasp that feelings and guess-work are not factual evidence and thus miss the “threat” factor. So it’s vital to help them understand the difference between emotion mind and rational mind.
What is the “threat” factor?
This is when a problem is perceived as a threat. For example, a person who has a harm obsession thinks about it with an irrational concept which links to over-importance of thoughts and catastrophising. Subsequently, emotional reasoning further clouds rational thinking and the person tends to question their actual values.
Can you expand on that?
Yes. Someone who has harm OCD (or another disturbing obsession) shows their actual values, which is, paradoxically, that they care deeply about people. The problem is that they cannot get past the barriers that confuse them when their intrusive thoughts “say” otherwise. They feel pinned down by OCD, fearing they are capable of putting thoughts to action. It’s not so simple to eradicate fears despite OCD being an incomprehensible disorder. People who have OCD are in conflict, they go over the relentless doubts when trying to understand thoughts in their head that can never be subject to analysis.
How can someone grasp this concept?
One example is known as The Theory A and Theory B experiment (Salkovskis & Bass, 1997). The person would look at their problem as worrying (theory B) about the thing that bothers them instead of fearing to be under threat (theory A).
How does this experiment work?
First, worry (theory B) is to feel anxious about something unpleasant that may have happened or could happen in the future; and threat (theory A) comes with “warning signals”. A person agrees in therapy to test out theory B by finding workable solutions to overcome their worry, thus removing the threat element. So on the subject of say contamination fears, one suggestion is for the patient to observe others interacting with each other and noting down the different types of responses that occur in this type of situation, which allows for rational concept. An example of both theories might be:
Theory A: The problem is that I feel anxious when I'm interacting with people; it's like they're all infected with HIV and I'm terrified I will contract this disease even without person-to-person contact.
Theory B: The problem is that I care very much about interacting with people and the thought of contracting HIV from someone causes me great distress.
By working on rational concepts for theory B means the threat element (theory A) starts to weaken, noted before.
Is it true that false memory confuses insight?
Well, let’s say memory tends to play tricks for a person who has OCD. When this happens, they will ruminate at length, searching their minds for abstract recollections. However, while they might remember an existing memory, even when some of that memory is lost, they will never recall a “vague” memory because it never existed.
It’s essential, therefore, to work with the person to locate the pieces of information that are true and filtering out the rest. As an example, let’s go back to the person who has a harm obsession. Let’s assume they were in the same area at a time when someone was hurt in an accident. Later, they might “add” to the memory a non-existent one in which they fear they might have been the one who harmed that same person. They have this fear because they were wearing a blue jacket similar to the person who caused the accident. Learning to live with uncertainty would be reinforced in therapy.
So living with uncertainty is one of the factors for reaching recovery, right?
Yes, this is one of the factors that is involved in the treatment plan for OCD and works better for people who have good insight.
Can a person’s insight improve?
Sometimes. Cognitive restructuring can help a person alter thinking errors linked to faulty ideas, although some often lose sight of their new healthier beliefs because their need for certainty overrides this. Pathological doubt clouds insight and drives behaviours to prove obsessions right or wrong, which makes exposure response prevention (ERP) more of a challenge when the person cannot grab hold of certainty. Improved insight can help them know that while they want this type of assurance that living with uncertainty is the better option. They start to see that feeling under irrational threat forever keeps the OCD going in a circle.
Can obsessions turn into delusions?
Yes, obsessions can turn into delusions and delusions can turn into obsessions. A person’s misconceptions in this instance aren’t to be confused with those seen in psychosis. For example, if insight into an obsession is poor/lacking then this shifts from overvalued idea to delusional belief; a belief in psychosis, however, is fixed and does not follow the regular OCD cycle.
For delusion in OCD, insight can be worked on with cognitive restructuring of thoughts to change the pattern or significance of those thoughts. When the delusion turns into an obsession, it shows that cognitive restructuring has illuminated insight, also exposure response prevention since practising exposures squeezes the obsession, improving insight.
A new perspective, plus a reduction in symptoms, allows the person to comprehend the significance of false versus real events concerning the obsession and to see that all real events are separate from it. For example, it’s true that the person was wearing a blue jacket at the scene involving injury, but this does not make valid the perception “What if I was the one who hurt the injured person”?
What else helps a person reach recovery?
Mindfulness techniques are helpful because these help someone do what I call the 3 A’s. These are to Acknowledge, Accept and Allow intrusive thoughts to come and go in the present without passing judgement. Including the 3 A’s into exposures is also helpful since this technique contributes to building distress tolerance in which ERP leads ultimately to remission.
First, cognitive restructuring helps alter thoughts, feelings and behaviours and improves insight. Subsequently, agreeing to face obsessions (exposures) and resist compulsions (response prevention) shows how this active process eventually weakens obsessions and aids in one’s recovery. When treatment comes to an end, a personal blueprint helps people maintain their gains. This blueprint details a new set of healthier beliefs together with behavioural/exposure strategies that worked during treatment, and to prevent a full-blown relapse in the future.
