The old Chinese saying “no break, no stand” refers to the process of changing things by eliminating the old factors that hinder the healthy development of things, cultivating and promoting the new factors that are conducive to the healthy development of things, and ultimately making things change in accordance with people’s wishes. For the treatment of obsessive-compulsive disorder (OCD), there is also the same requirement of not breaking and breaking. To a large extent, the mental activities of patients with obsessive-compulsive disorder (OCD) are dominated by obsessive-compulsive symptoms; they are trapped in the quagmire of obsessive-compulsive symptoms, and they also have the “bitter love” that accompanies obsessive-compulsive symptoms, which leads to the corresponding functional damage, and they also establish the balance or homeostasis of the interrelationships between their intrinsic mental activities and the external world. Therefore, most of the diagnostic criteria for OCD use the degree of subjective suffering caused by the obsessive-compulsive symptoms and the length of time consumed by the obsessive-compulsive symptoms as a measure of the degree of functional impairment and the corresponding severity criteria. In strategies for treating OCD, reducing the degree of subjective distress caused by obsessive-compulsive symptoms and reducing the length of time consumed by obsessive-compulsive symptoms are important criteria for determining the effectiveness of the treatment measure. Since the clinical manifestation of OCD consists of three interrelated symptoms: obsessive-compulsive thinking as the initial symptom, anxiety or other emotional symptoms caused by obsessive-compulsive thinking, and behavioral symptoms such as compulsive behaviors to reduce anxiety caused by obsessive-compulsive thinking, treatment strategies or methods will be chosen to address these three symptoms. For example, cognitive therapy can be used to treat obsessive-compulsive thoughts that come into the mind involuntarily, and to reduce the patient’s concern and emotional reaction to the abnormal experience. For anxiety, anti-anxiety treatment with medication and biofeedback can be used to reduce the emotional response. For obsessive-compulsive behaviors, behavioral therapy with exposure and response prevention as the core method can be used to reduce the frequency of their committing obsessive-compulsive behaviors. The combined application of these three measures has shown definite efficacy in OCD. However, regardless of any of these treatments, the balance or homeostasis of the interrelationship between the patient’s inner mental activities and the external world, which the patient has been better adapted to prior to treatment, will be disrupted, and the patient will need to establish a new balance or homeostasis in a timely manner. Before receiving formal treatment, a considerable amount of the patient’s inner mental activity and energy and time are adhered to or consumed by the obsessive-compulsive symptoms, making it impossible for him or her to have enough time and energy to establish a sufficiently effective connection with the external world. In other words, the patient is more absorbed in the subjective world constructed by his or her obsessive-compulsive disorder than in the objective real world, and becomes an “addict” and “dependent” on the obsessive-compulsive symptoms. After the beginning of treatment, the patient’s obsessive-compulsive symptoms will gradually decrease, and the obsessive-compulsive component of his internal mental activity will become less and less. In most patients, after the reduction of obsessive-compulsive symptoms, there is a “gap” in mental activity that used to be filled by obsessive-compulsive symptoms, and the patient may even become “maladaptive”. At this time, to help or guide the patient to find some with the patient’s interest, age, identity of the healthy activities such as socialization, development training, interest camps, collective nature of the sports, etc., can make it easier for patients from the obsessive-compulsive symptoms of the entanglement of the release, and more likely to get a better therapeutic effect. Therefore, in the treatment of obsessive-compulsive disorder, we need to take into account the “break” and “establish”. The so-called “breaking” means eliminating the original behavioral patterns with obsessive-compulsive characteristics and the tendency of “addiction” and “dependence” on obsessive-compulsive symptoms. The so-called “establishment” means to establish a behavioral pattern and interest activities that can completely get rid of OCD. Only in this way can OCD be truly cured.
