The obsessive thinking that involuntarily appears in the minds of patients with obsessive-compulsive disorder (OCD) will lead to obvious anxiety, so the patients will take the initiative to implement some behaviors that have the effect of relieving anxiety induced by obsessive thinking, and these behaviors are obsessive-compulsive behaviors. In the initial stage of OCD, the patient performs compulsive behaviors that have the effect of directly relieving anxiety, but as the disease progresses, the effect of these compulsive behaviors in relieving anxiety is weakened, and they gradually evolve into stereotypical and repetitive ritualized behaviors. Although in psychiatry textbooks, some authors believe that some patients have only obsessive thinking without obsessive behavior, or only obsessive behavior without obsessive thinking, but in my own clinical practice, I have almost never seen the two disjointed obsessive-compulsive patients, that is, as long as there is obsessive thinking, there is obsessive behavior. Because, compulsive thinking is the cause, compulsive behavior is the result, there is no compulsive thinking will not have compulsive behavior, otherwise the compulsive behavior will be the root of the wood, the source of the water. It is only because some compulsive behaviors are more hidden or unobtrusive, making it difficult for doctors to identify them. Although there are many variations and shapes as far as the manifestations of obsessive-compulsive behaviors are concerned, there are essentially some basic characteristics that can be used as a simple classification. Based on my observations of patients with OCD in recent years and my generalization and sorting out of obsessive-compulsive behaviors, it is possible to broadly classify obsessive-compulsive behaviors according to the following two frameworks: first, according to whether the obsessive-compulsive behaviors are externally or internally manifested, and second, according to whether the obsessive-compulsive behaviors are idiosyncratic or non-idiosyncratic. Classifying compulsive behaviors in this way helps both to identify compulsive behaviors and to correct them through behavioral therapeutic means. Overt Compulsive Behavior and Implicit Compulsive Behavior The so-called overt compulsive behavior (overt compulsions) refers to the patient’s use of external behavioral actions that can be observed by others as a measure to alleviate or offset the anxiety induced by obsessive-compulsive thinking during the course of the disease. For example, a patient who suspects that he or she has failed to securely lock the door to his or her home will verify that the door is locked by repeatedly inserting the key into the lock hole and turning it forward and backward, which is an overt compulsion to verify the behavior (overt complsive check). Because overt compulsive behaviors can be observed by others, they are almost invariably correctly identified by psychiatrists and rarely lead to misdiagnosis. Covered compulsions, on the other hand, are programmed internal activities that the person with OCD does to relieve or counteract anxiety, and they serve the same function as overt compulsions. Some of the covered compulsions are based on a pattern of compulsive verification, in which the patient repeatedly recalls every “key” detail of the behavior to confirm that the behavior has been completed perfectly and accurately, instead of actually verifying the results of the behavior in the field. For example, the patient recalls the depth of the key inserted into the lock hole, whether the direction of the key was clockwise or counterclockwise, whether the key was rotated 180 degrees or 360 degrees, and the details of the synchronized events in the surrounding environment during the locking of the door, and uses these impressions as evidence of the completion of the act of locking the door. Some people call this symptom “obsessive-compulsive recall” and consider it to be a symptom of obsessive-compulsive thinking, but I think this is a misclassification. In my opinion, this phenomenon can be compared to “playing a movie” or “playing a live video”. The other part of implicit compulsive behavior is to imagine or fantasize the implementation of certain compulsive behaviors or actions that are difficult to implement in real life situations, also as a substitute for implementing the corresponding explicit compulsive behaviors in real life situations. For example, the patient imagines what action he or she accomplished in the first step, what position he or she took in the second step, how the bystanders in the surrounding environment reacted, and how he or she responded with his or her own words or actions, etc., so that they are presented in a sequential form in the patient’s mind as a perfect substitute for completing a certain behavioral process. In contrast to the analogy of implicit verification behavior as “showing a movie,” this type of implicit compulsive behavior can be compared to “acting out a play,” which is a process in which the patient plays out a script that he or she has developed or fantasized about. This is a process in which the patient plays the role according to a “script” that he or she has developed or fantasized about. The problem that needs to be raised in particular is that it is wrong to define certain implicit compulsive behaviors as obsessive thinking in previous textbooks. For example, one textbook describes obsessive-oppositional thinking as a kind of obsessive-compulsive thinking, stating that a catastrophic concept such as “war” that causes fear and anxiety involuntarily appears in the patient’s mind, and the patient searches for the opposite of the word in his mind with a peaceful meaning such as “peace”, recites it several times silently, and then says “peace” to himself. The patient then searches his mind for the opposite, peaceful concept such as “peace” and recites it several times to counteract the fear induced by the catastrophic concept. In fact, this process gives rise to two separate symptoms – obsessive thinking and obsessive behavior: the involuntary surfacing of the catastrophic concept is obsessive thinking, and the autonomous search for the opposite concept is obsessive behavior. Of course, there are other forms of implicit obsessive-compulsive thinking, such as compulsive counting and compulsive “chanting”, which have been described in textbooks, so I will not repeat them. Specific compulsive behavior and non-specific compulsive behavior The so-called “specific compulsive behavior” (specific compulsion) refers to those who have a specific target to alleviate or counteract the anxiety induced by a particular compulsive thinking compulsive behavior. For example, patients who are worried about staining (taining) unclean objects compulsive thinking, in real contact or subjective suspicion of contact with the unclean objects identified by the patient, when conditions permit, immediately implement the “cleaning rituals”, such as washing, changing clothes, discarded, etc., that is, with the fear of staining unclean objects of the obsessive-compulsive thinking corresponds to the specific compulsion behavior. behavior. Another example of idiosyncratic obsessive-compulsive behavior is the patient’s obsessive suspicion of not locking the door properly. Whether he or she verifies the locking process with explicit obsessive-compulsive verification behavior, or verifies the locking process with implicit verification behavior to alleviate the corresponding anxiety, this kind of verification behavior is idiosyncratic obsessive-compulsive behavior. It can be said that specific compulsive behavior is “one key opens one lock”. Patients with obsessive-compulsive thinking who are contaminated with unclean objects cannot eliminate their anxiety through the obsessive-compulsive verification behavior of checking whether the door locks are locked or not. Conversely, patients with obsessive-compulsive thoughts who worry about unlocked doors cannot reduce their obsessive-compulsive thinking-induced anxiety through cleaning rituals. Non-specific compulsive behaviors (unspecific compulsions) is the obsessive-compulsive disorder patients in the emergence of obsessive thinking-induced anxiety, can not find a specific targeted compulsive behaviors to alleviate their anxiety, will try some less specific targeted behavior, and it happens to be that this behavior can effectively reduce the patient’s anxiety, regardless of this behavior is specifically what behavior is non-specific compulsive behavior. specifically targeted compulsive behavior. For example, a female patient’s mind involuntarily surfaced some obscene images or extreme bloody and violent scenes, making her anxiety fear, open, unbearable, she may go to the school stadium to engage in strenuous sports such as long-distance running to “divert attention”, and then reduce anxiety. In the future, whenever she has obsessive-compulsive thinking that induces anxiety, she will go to the stadium to engage in strenuous sports to alleviate her anxiety. This kind of behavior belongs to non-specific obsessive-compulsive behavior. Non-specific obsessive-compulsive behavior is like a master key that “opens a thousand locks with a single key,” adapted to alleviate or counteract anxiety induced by a variety of obsessive-compulsive thoughts. These patients, if later in the course of the disease, obsessive-compulsive thoughts evolve or change, often used to adopt the strategy of “responding to changes with no change”, repeated use of its “tried and true” non-specific obsessive-compulsive behavior.
