Including questions about ADHD on national or regional surveys helps us learn more about the number of children with ADHD, their use of ADHD treatments, and the impact of ADHD on children and their families.ĬDC also conducts community-based studies to better understand the impact of ADHD and other mental and behavioral health conditions. Researchers then selected a sample of children with many symptoms of ADHD, as well as a sample of children with few or no symptoms, and asked parents for a more in-depth assessment.ĬDC monitors the number of children who have been diagnosed with ADHD through the use of national survey data.

Parents need to be aware of the findings because ADHD is complex and can be difficult to assess and diagnose parents who have concerns about a child with behavioral problems should seek treatment from an experienced professional who can conduct a thorough evaluation.Clinicians need to be aware of the findings because they show that differences in how criteria are used to diagnose ADHD can affect how many children are diagnosed.

1 in 9 children (11%) had ADHD if researchers required that a teacher also reports symptoms-further reducing the estimated prevalence of ADHD by half.Īpplying each DSM-5 criterion reduces the percentage of children aged 4-13 years who fit diagnostic criteria for ADHDĭownload icon Download Image Main Findings Implications.1 in 5 children (22%) had ADHD if researchers also included those who had the symptoms by age 12 years and showed functional impairment.Nearly 1 in 3 children (30%) had ADHD if a parent reported 6 or more symptoms of ADHD.There was a steady decrease in estimated prevalence as more diagnostic criteria were used. The percentage of children (4-13 years old) meeting criteria for ADHD was higher if the DSM-5 criteria are used than if the DSM-IV criteria are used (11% versus 9%) because the age of onset of symptoms requirement was changed from being less than 7 years old to being less than 12 years old. Often all of the criteria are not used, but as the results of this study showed, using only some of the criteria clearly has an effect on the estimated prevalence. More than one type of person observes and reports on the child’s symptoms (e.g., parent and teacher).Symptoms cause impairment in more than one setting (e.g., home and school), and.
First, they estimated the percentage of children aged 4 to 13 years who meet criteria for ADHD using the most recent version of the American Psychiatric Association’s Diagnostic and Statistical Manual, Fifth edition (DSM-5). Researchers from the CDC, the University of Oklahoma Health Sciences Center, and the University of South Carolina found that the estimates of ADHD prevalence vary greatly by which ADHD criteria are applied.ĭata from the Project to Learn about ADHD in Youth (PLAY) was used to examine the impact of using different diagnostic criteria to estimate the prevalence of children with ADHD. The Journal of the American Academy of Child and Adolescent Psychiatry has published a study, The Impact of Case Definition on ADHD Prevalence Estimates in Community-Based Samples of School-Aged Children, looking at the difference in the estimated percentage of children who have Attention-Deficit/Hyperactivity Disorder (ADHD) when the condition is defined in different ways.
