Compulsive behavior in children is one of the symptoms of obsessive-compulsive neurosis, which mostly occurs in children between the ages of 10 and 12. Although some “compulsions” can occur in normal children at a young age, such as kicking stones when walking or touching poles with their hands, they are transient and disappear naturally as they get older. Unlike children with pathological compulsive behaviors, they are not easy to correct on their own, and if they are not allowed to repeat these actions, they will feel unbearable, anxious and even lose their temper, and will only be comfortable if they do it repeatedly. Unlike adults with compulsive behavior, children do not feel distressed or regretful about this abnormal behavior. The formation of compulsive behavior in children is related to a variety of factors such as innate qualities, their own personalities, poor parental character, and improper educational methods. Such children often have overly serious, formal, timid, thoughtful, stereotypical, tidy and other personality characteristics before the disease. Their parents also have mostly psychotic personality traits, such as timid and fearful, overly cautious, lack of self-confidence, do things muttering, etc.. The bad personality combined with improper education, demanding parents and other factors, it is easy for the child to induce obsessive-compulsive symptoms. Children who suffer from certain diseases or have a history of head trauma or psychological trauma are also susceptible to the development of this disorder. What can be done to prevent compulsive behavior in children? Generally, no medication is needed, but education and psychological support should be the main focus. Parents should correctly understand the pathological behavior of the affected child and should not scold or punish. They should help their children to find the causes and encourage them to restrain themselves. Let them participate in group activities and have more contact with the outside world to distract them from the compulsive behavior, which can be slowly reduced or disappeared. Parents must improve their education methods, more praise and encouragement, less blame and ridicule, so that the child is not psychologically stimulated. In severe cases, psychotherapy and behavioral treatment can be provided by a specialist (psychiatrist).
