OCD is a psychologically complex disorder that is characterized by a lack of confidence in oneself and the need to do something over and over again before one is convinced that one is right. OCD has a major relationship with the overly strict and rigid parenting style of their parents and their pursuit of a perfect life style. It is right to expect children to develop careful habits from an early age, but not to the extreme. Daily life should be combined with an easy-going and flexible style, and the basic requirement is to adapt to the psychological characteristics of society and the majority of people in line, not to deviate seriously. Once a compulsive personality defect is detected, it must be actively corrected by a medical specialist. In addition, it should be understood that the prevention of obsessive-compulsive personality defects is important for the prevention and treatment of OCD. 1. Do not be overly concerned about self-image. Do not pursue perfection too much, do not always ask yourself, “Did I do well? Is this okay? What will others think of me?” And so on. 2, learn to let nature take its course. Another characteristic of OCD is that it likes to think, a sesame grain of things will often come up with a big thing. Therefore, in thinking about the problem to learn to accept others, do not take the bull by the horns, learn to adapt to the environment rather than deliberately change the environment. 3, learn to enjoy the process. Do not put too much emphasis on the results, should be for what is done. Do things to hold an appreciation of feelings, experience the joy of the mood, pay attention to the process do not pay too much attention to the results. 4.Have a correct and objective understanding of your personality characteristics and the disorder you are suffering from. Have a correct and objective judgment of the reality of the situation, throw away the baggage, reduce the sense of insecurity. Learn reasonable stress management methods, enhance self-confidence to reduce their sense of uncertainty, not overly ambitious, not too much pursuit of excellence to reduce their sense of imperfection. 5, family and friends to the patient is neither tolerated, nor overkill. Encourage the patient to actively engage in useful cultural and physical activities, so that they gradually free themselves from the compulsive situation. 6, self-regulation can not solve the problem, if necessary, ask a psychologist to implement psychotherapy. For example: behavior therapy, cognitive therapy, psychoanalysis, etc. Systematic desensitization therapy can also gradually reduce the number and duration of repetitive behavior. 7.Medication. The effect of medication on the treatment of OCD is also very positive, about half of the patients may get rid of OCD through medication.
