In order to decide if a child or adolescent has an Anxiety Disorder, professionals will need information as to how often the child has been anxious and if it has continued despite steps taken to alleviate it. They will decide if the fears are normal for the child's age and will evaluate the degree to which the anxiety interferes with the child's life. A professional will also take a close look at people or situations that may be unwittingly reinforcing the child's anxious behaviors. Some children and adolescents with anxiety disorders benefit from a combination of treatments.
