In nearly two decades of child and adolescent psychological and mental health work, often see some delayed diagnosis of intervention children, while seeing parents in children’s mental mental health often have certain misconceptions: 1, the importance of intellectual ability, self-brewed bitter wine: some parents only value academic performance, the misconception that children learn well enough; a day from morning to night only require children ” Learning, learning, learning again,” and think that “points, points, points, the life of the student”; but do not pay attention to the comprehensive quality of children’s training, sound psychological development and social adaptability, for the first signs of psychological problems parents do not pay enough attention, think that good learning can replace everything. As a result, “good students” are at a loss when they enter the society, and even reveal their psychological problems during university and study abroad, and perform such lamentable tragedies as “Lu Gang” and “Liu Yang”. 2, poor knowledge, not enough attention: parents lack knowledge of children’s mental health, think that some of the child’s behavior, emotional disorders are just children do not know how to, naughty, or think that some performance in the child can be self-healing when they grow up, and failed to mention the psychological disorders to the intervention agenda. Indeed, some children’s mental disorders such as attention deficit hyperactivity disorder will be reduced or even disappear as the neurological development gradually becomes sound with age; however, inattentive and impulsive behavior will continue into adulthood, which will seriously affect their academic performance and social adaptability, and the negative attitudes of parents and teachers toward the affected children caused by the hyperactivity stage can affect the child’s psychological development This can also affect the child’s psychological development and personality formation. Some scholars have found that the socioeconomic status of children with attention deficit hyperactivity disorder in adulthood is relatively lower than that of people without a history of ADHD. Parents are aware of their children’s psychological problems but are afraid of being looked down upon by others, and do not choose to see a child mental health professional because of their “reputation”. In fact, mental illness and physical illness should be treated equally, both have their biological basis, and both should see a specialist according to different body systems. Only after diagnosis by a specialist can we distinguish whether it is a normal emotional reaction, a mild psychological problem, or a serious mental illness, and professional treatment with a clear diagnosis can curb the development of the disease. In particular, the limited number of doctors nationwide in the child and adolescent mental health industry should be chosen carefully. Often encounter children with several twists and turns of medical treatment to no avail, gradually appeared some accompanying symptoms, the condition is becoming more and more powerful; therefore, to see a specialist medical treatment, or eventually delay the disease. 4, lack of communication, each holding their own views: most of the child’s time is spent in school, the teacher’s observation and help is essential, frank communication with the teacher to work together to make the child have a more conducive to its development environment. This also requires a great deal of love and a scientific concept of health: two parents reported that the teacher “kindly” discouraged the child from seeing a doctor when the parents thought they had doubts about whether the child was ill, and that the child would be fine when he or she was older; although some manifestations may disappear with age, the child’s psychological development is affected during the course of the illness. The child’s psychological development is greatly affected during the course of the illness. Teachers should take a holistic and long-term view of the child. Therefore, only through communication and cooperation between parents, teachers and doctors can children develop normally and comprehensively. 5, the root of the parents, family discord: parents work under great pressure, after returning home in front of the child too relaxed, some bad habits are on display, the child learned some bad behavior. In addition, parents work under pressure, can not find the problem in time, and will not take the child to the doctor in time, delaying the child’s treatment time. In addition, the relationship between husband and wife is not good, the family environment is not good, resulting in children and adolescents psychological development is not sound, and even very young children will have emotional and behavioral problems. Even if the child suppresses the childhood psychological conflict, as an adult, this seed is likely to grow bad branches in a certain situation. Some scholarly research indicates: ADHD children’s family intimacy, emotional expression, knowledge, success is lower than normal children’s families, and family conflict is high. 6, avoiding the important, because of the small loss: parents are overly concerned about drug side effects, and reluctance to take medication. However, the consequences of not taking medication is the delay of the disease, affecting the psychological development of children and adolescents. The consequences greatly exceed those caused by the side effects of drugs. This should be seen in the context of a doctor’s opinion. There was a child with Tourette’s syndrome who was secretly transferred to a Chinese medicine doctor after taking medication to improve his condition, and six months later his condition rekindled. All of the above factors can affect the treatment of children and adolescents, thus affecting the normal growth of children. This shows that a comprehensive, macro, long-term, scientific view of children’s psychological problems is the wise thing to do for parents. At the same time, the healthy psychological growth of children and teenagers can only really improve the quality of the population of the next generation if it is taken seriously by the whole society. Let’s pay attention to the mental health of children and teenagers together!
