In recent years I have been focusing on obsessive-compulsive disorder and its spectrum disorders, and over time I have discovered that obsessive-compulsive symptoms have characteristics that were not previously described in textbooks. Among these are generalization, involvement, and addiction, which are three features that have not been described before but need to be recognized. During the development of OCD, compulsive symptoms are characterized by generalization, involvement, and addiction. In this process, there is a single effect of positive reinforcement, a single effect of negative reinforcement, and a single effect of reinforcement of both natures, making the compulsive symptoms increasingly severe. Generalization refers to an increase in the number of compulsive thoughts and compulsive behaviors within the same level of symptoms. For example, a patient who is worried about having an infectious disease of the digestive tract due to contamination with unclean substances may be concerned at the beginning of the disease with the possibility of the disease being caused by contact with unclean substances by hand. After the disease has progressed to a certain level, they may become concerned about the possibility of getting sick by inhaling unclean substances through the respiratory tract. In the past, the anxiety of contacting unclean objects with hands could be alleviated by performing cleaning rituals such as washing, but now, the anxiety of ingesting unclean objects such as dust through the oral cavity can be alleviated by performing cleaning rituals such as spitting and weezing, and the anxiety of inhaling disease-causing ingredients through the nasal and upper respiratory tracts can be alleviated by performing cleaning rituals such as coughing, spitting, and even spitting. I believe that this form of “pancake staging” to increase the content of compulsive symptoms is a form of generalization of compulsive symptoms. Entanglement refers to an increase in the form and content of obsessive-compulsive thoughts and behaviors in different symptom categories that may not be logically related. For example, the same patient with OCD whose core compulsive thinking is the fear of contamination with unclean objects is an example. In the initial stages they may simply be afraid to enter the hospital to touch objects in the hospital for fear of being infected with the disease. As the disease progresses, patients may begin to be afraid to eat at restaurants near the hospital, fearing that medical staff or patients and their families will eat at these restaurants, that there will be potentially disease-causing impurities left on the tables, chairs, or utensils they touch, or that they will inadvertently touch any vehicles they see entering or leaving the hospital, and even engage in avoidance behaviors accordingly. As the disease progresses, the patient’s fears become more and more complicated, such as fearing that there are disease-causing agents in the dust and being heavily armed to guard against them, fearing that someone on the building is throwing garbage and accidentally injuring or defiling their bodies and stopping frequently to watch, fearing that they are allergic to inhaled pollen and avoiding flowers, and so on. This is a form of “snowballing” that increases the content of obsessive-compulsive symptoms. Addicton means that once a person’s compulsive symptoms start to become more and more complicated, his or her compulsive behavior may become more and more complicated through the pattern of addictive behavior, and then form a continuous, programmed ritual behavior. According to the definition of addictive behaviors, addictive behaviors (ADDICTIVE BEHAVIOR) is an additional overwhelming addiction and habituation that develops through stimulation of the central nervous system resulting in a feeling of euphoria or pleasure. The concept of addiction comes from drug addiction and refers to an individual’s uncontrollable and repeated craving to engage in a certain activity or abuse a certain drug, which is uncontrollable despite the fact that doing so will bring or has brought various unmeasured consequences to oneself. Compulsive behavior is also characterized by the ability to reduce or alleviate the anxiety and fear induced by compulsive thinking, and the patient’s ability to “supplement” and “refine” the compulsive behavior in the process of doing so, almost without restraint, in order to achieve the greatest possible reduction of anxiety and fear. At the same time, the compulsive behaviors are constantly “supplemented” and “refined” in the process of implementation in order to achieve better anxiety relief. Moreover, the patient’s anxiolytic effect is temporarily enhanced by increasing the complexity of the compulsive behavior and progressively refining the “perfection” of the compulsive behavior, so that the patient enjoys it. Even if the patient later discovers that the implementation of the newly increased complexity of the compulsive behaviors only ends up putting him or her back in more painful “chains,” the patient will not give up the hemlock. During the period of compulsive behavior, the patient will continue to engage in the compulsive behavior as long as there are no strong interventions in the environment to stop the compulsive behavior or stimuli that produce a stronger temporary relief of anxiety and fear than the compulsive behavior. In the behavioral treatment of OCD, it is based on this principle that the compulsive behavior is either forcibly prevented or replaced with other activities that have a more effective anxiolytic effect. Patients have even been known to play video games to reduce the compulsive behaviors that can cause them more pain. This is a form of addiction that increases the complexity and time spent on compulsive behaviors, like the mobile game “Snake”. Both the ease of generalization, the ease of involvement, and the ease of addiction reflect the pursuit of “perfection”, “infallibility”, and “I would rather kill a thousand by mistake than release one by mistake” in the development of OCD. “The pattern of pathological mental activities or stereotypes of thinking and behavior.
