As many as 20% of children and adolescents may have a diagnosable mental health disorder that causes some sort of impairment. The risk of being diagnosed with a mental health disorder increases with age. By some estimates, about 30% of adolescents between the ages of 13 and 17 meet the criteria for two or more mental health disorders. Environmental stressors (eg, the COVID-19 pandemic) may disrupt critical routines and relationships enough to make even otherwise resilient children and adolescents more vulnerable to mental health disorders.

With a few exceptions, symptoms of mental health disorders tend to be similar to feelings that every child experiences, such as sadness, anger, suspicion, excitement, withdrawal, and loneliness. The difference between a disorder and a normal feeling is the extent to which the feeling becomes so powerful as to overwhelm and interfere with the activities of normal life or cause the child to suffer. Thus, doctors must use a significant degree of judgment to determine when particular thoughts and emotions stop being a normal component of childhood experience and represent a disorder.

Diagnosis of Mental Health Disorders in Children

  • Observations

  • Sometimes specialized interview and assessment tools

No test can confirm the diagnosis of a mental health disorder. Doctors rely on an interview with the child or adolescent and observations of parents and teachers and on those made during the office visit to help determine whether a mental health disorder is present. Sometimes doctors refer the child or adolescent to a mental health care practitioner who is trained to diagnose and treat mental health disorders in children and adolescents. These practitioners may use specially designed interview and assessment tools to evaluate the child.
