Obsessive-compulsive disorder (OCD) is a group of mental disorders characterized by recurrent intrusive thoughts, impulsive ideation and stereotyped, repetitive behaviors, most of which start in adolescence and are prolonged, with varying degrees of functional impairment. The clinical manifestations of obsessive-compulsive disorder (OCD) mainly include both obsessive thinking and obsessive-compulsive behavior, which belongs to a type of anxiety disorder. The onset of OCD is related to psychosocial, personality, genetic and neuroendocrine factors. The first two of these can be intervened, so how should they be intervened and treated? Some children in different stages of development, there will be some similar obsessive-compulsive behaviors, such as going up the stairs to count the number of steps, crossing the crosswalk to count the grids on the road, touching objects other than the body will keep washing their hands, checking the windows and doors over and over again to see whether they are closed tightly, the quilt must be repeated to the corners of the quilt to be neatly aligned, and the shoes must be placed in a fixed position and placed in a fixed way, etc. If these behaviors do not cause to the child If these behaviors do not cause strong emotional fluctuations in children and do not affect their normal learning and life, they will slowly disappear when they grow up. If there is a traumatic experience in childhood, or if the needs are not met due to parental neglect, this is a negative factor for the child, which will cause the child to have different degrees of influence on the individual’s cognitive and behavioral aspects, which will lead to the individual’s behavioral, cognitive, and emotional disorders. In childhood, parental discipline, denial and rejection will prompt some children to form a high standard of self-requirement, resulting in their failure to meet the requirements and often self-condemnation, a sense of shame, which will provide the conditions for the emergence of obsessive-compulsive disorder (OCD), prompting some children to become a compulsive thinking perfectionist. The pursuit of perfection is a personality trait tendency, in order to get the attention and praise of parents, they always set some high or unrealistic goals for themselves, excessive pursuit of perfection and often in the self-complaints, obsessive-compulsive thinking often causes self-perception defects. This kind of perfectionism will also be manifested in the behavior, manifested as repeated thinking, repeated checking and other obsessive-compulsive symptoms. For example, you have to check the same thing many times before you feel relieved; you always worry that you will forget something important, such as forgetting to lock the door of your room; you always think that you are afraid of being dirty, germs, chemicals, etc., and thus take excessive baths and wash your hands over and over again; you keep things at home that you think you can’t throw away, which are actually not useful; you are always worried that you will have offensive words or behaviors, and therefore you will avoid some people and scenes deliberately. some people and scenes, etc. Although patients experience that such thoughts or impulses come from themselves and try their best to resist them, they are never able to control them, and the strong conflict between the two makes them feel great pain and anxiety, which affects their work and study, interpersonal interactions and even their daily life. Some parents of OCD patients often have some psychological problems, such as depression, anxiety, obsessive-compulsive, hostile, paranoia, interpersonal relationships, somatization and other mental symptoms will be higher than normal, their parenting style will often affect the quality of life of the child, and have a negative impact on him or her. Some parents also adopt an overprotective parenting style for their children, which puts them in a state of low social functioning, or adopt an overly strict approach to educating their children, forcing them to become perfectionists with lowered self-esteem. Therefore, in order to better improve the quality of life of patients with OCD, it is also very necessary to provide psychological intervention for patients’ parents. So that the patient’s parents learn to treat the patient in a correct and scientific way, do not hold too high expectations and excessive worries, do not strengthen the child’s behavioral concepts because of their own pathological concepts and behaviors, and work together to face life with a positive and calm mindset, creating a good family environment for the patient’s treatment and recovery. If you have OCD, you should actively go to the hospital to receive systematic medical intervention. Pharmacological intervention To maximize the relief of patients’ symptoms, reduce the frequency of attacks, let patients understand the importance of medication, improve patients’ adherence to medication, so as to improve patients’ mental symptoms and improve their quality of life. Psychological intervention 1. Cognitive comprehension therapy. Usually the psychiatrist discusses and analyzes the nature of the clinical manifestations of the symptoms directly with the patients, so that they recognize the childishness of the pathological feelings and behaviors, and realize that these feelings and behaviors are the psychological and behavioral patterns of a young child, which are incompatible with his actual age and identity, and thus voluntarily give up these thoughts and behaviors. 2. Behavioral intervention. Adopt exposure therapy and reaction prevention method, let the patient imagine or closely contact with uncomfortable scenes and things, not allowed to do ritual actions, so that he gradually adapt to the patient when the patient appeared to compulsive actions to divert his attention in time, so as to reduce compulsive actions, to restrict his compulsive behavior, and encourage the patient to take part in physical exercise and public recreational activities. 3.Supportive intervention. Provide comfort and guidance for the unpleasant and painful emotions and mental factors, explain that the bad emotions are generated by the obsessive-compulsive concepts, relieve the psychological pressure of the patients, make the patients realize that all kinds of misgivings are unrealistic, thus correcting the patients’ misperceptions to alleviate the sense of insecurity, not excessively pursuing the perfection, and adopting a tolerant and accepting attitude towards themselves and things, so as to improve their own character. 4.Family intervention. A good family environment and the healthy concepts and behaviors of family members play a role in promoting the recovery of patients. As parents should build a harmonious, stable and safe living environment for their children, do not be overly demanding of their children, communicate more with their children, and deal with things more flexibly, in order to promote the construction of a sound personality of the child.
