In the clinical work of diagnosing and treating patients with obsessive-compulsive disorder (OCD), I often find that the obsessive thinking and various forms of obsessive behaviors of OCD patients, including the concept of hypervalence, have a specific meaning that is “determined”, “set” or “prescribed” by the patients themselves. The specific meaning of the obsessive thinking and various forms of compulsive behaviors, including overvalued ideas, is “determined”, “set” or “prescribed” by the patients themselves, which does not need to be verified by logical scientific methods or confirmed or falsified by the experience of other people, and which I collectively refer to as the characteristic of “self-righteousness”. It is for this reason that the obsessive-compulsive symptoms of OCD are so critically misperceived that they are ideally suited for Cognitive Behavioral Therapy (CBT). All of the obsessive thoughts of people with OCD have a self-identified meaning. For example, most people with the so-called “cleanliness” type of OCD identify almost everything and everyone in their environment as “dirty”. They may feel that the seats and armrests of the bus are “dirty”, and subjectively believe that some passengers may be suffering from infectious diseases such as “AIDS” or “hepatitis”, and may be infected by touching the seats or the armrests. The subjective belief that some passengers may have infectious diseases such as “AIDS” or “hepatitis” and may spread the virus by touching the seats or armrests, and that they may be infected with these diseases if they sit on the seats or touch the armrests that they have sat on. They may think that the door handles or flush buttons of public toilets have been soiled by unhygienic people, and they may be infected with the disease if they touch these contaminated door handles or flush buttons directly with their hands. These patients have not investigated whether there are AIDS or hepatitis patients among passengers, nor have they systematically studied the knowledge of related infectious diseases, let alone using medical means to test whether there are disease-causing microorganisms on the bus seats or handrails, and have formed the corresponding conclusions entirely on the basis of the self-identification of “a flash of insight”. Similarly, those patients who believe that public toilet door handles and flush buttons are unclean have not done so, but also through such self-identification to make judgments and decisions. By extension, patients with other forms of OCD also follow this pattern of self-identification of corresponding “dangers” such as burglary of a home by leaving the door unlocked, or fire by leaving the power plug unplugged, and so on, in the same way. Based on such absurd “identification” which has no scientific or empirical basis, the patient’s fear and anxiety are aroused, and the patient has the impulse to carry out compulsive behaviors, and the patient is bound to carry out the compulsive behaviors which are initially able to alleviate the anxiety, and then the effect of alleviation of anxiety decreases with the prolongation of the course of the disease. Similarly, all the compulsive behaviors of the obsessive-compulsive disorder patients are also self-identified or “set”. Take “cleanliness fetish” as an example, some patients achieve the goal of “cleaning dirt” through “forced washing”, i.e., by repeating the washing behavior in a stereotypical manner, to achieve what they consider to be the goal of “cleaning dirt”. Some patients achieve the goal of “cleansing dirt” through cleaning rituals such as “forced washing”, i.e., the stereotypical repetitive washing behaviors to achieve the degree of “cleanliness” that they consider themselves to be, while others complete intricate, complicated, and procedural rituals or “routines” with the meaning of “avoiding disasters” through cleaning rituals to relieve their inner fear of “avoiding disasters” and “avoiding disasters”. Other patients complete intricate, complicated, and programmed rituals or “routines” through cleansing rituals, which have the connotation of “avoiding disaster”, in order to alleviate their inner fear of “disastrous consequences” brought about by washing that does not conform to the program. For the first type of washing, I define it as “washing for nothing,” meaning washing for the purpose of cleansing. For the latter, I define it as “washing the program”, meaning that it is oriented towards the completion of its fixed “routine”. Among these compulsive behaviors, “ritualized compulsive behaviors” that target certain obsessive overvalued concepts are characterized by both self-identification and self-setting. For example, the patient’s conviction that if he does not repeat an action according to his predetermined number of “lucky numbers”, he will be in big trouble, and the role assigned to the compulsive behavior is self-identified, and his choice of lucky numbers (e.g., “three” or “six”) is self-identified, as is his choice of “three” or “six”. The role assigned to the compulsive behavior is self-identified, and the choice of lucky numbers (e.g., choosing “three” or “six”) is self-imposed. Other forms of obsessive-compulsive behaviors are often self-identified or set, such as the use of repeatedly checking the number of times a door is locked, repeatedly checking whether the items carried in the handbag are complete, etc., which all have similar “self-identified” or “self-set” characteristics. Both obsessive thinking and obsessive behavior are characterized by “self-righteousness”. In layman’s terms, this kind of self-righteous obsessive-compulsive symptom is that the patient digs a huge pit for himself, and then jumps into the pit and buries the earth very hard on himself, which ultimately causes him to fall deeply into it and be unable to extricate himself from it, and his quality of life and social function are seriously impaired. The reason for this phenomenon boils down to relatively naive mental activity and especially naive level of cognitive functioning, and cognitive-behavioral therapy is important for such cognitive patterns.
