CDC researchers have published a National Health Statistics Report, Diagnostic Experiences of Children with Attention-Deficit/Hyperactivity Disorder. It is the first national study presenting greater detail on how ADHD diagnoses take place among a representative sample of children who have ADHD, as described by their parents. Findings from this report can be compared to American Academy of Pediatrics’ (AAP) clinical practice guidelines for ADHD, which recommend using standardized rating scales to diagnose ADHD and information from multiple sources (parents, teachers, other family members, etc.).

CDC researchers found from parent reports that about half of children were diagnosed by a primary care physician, behavior rating scales were used for 9 in 10 children to assess for ADHD, and about 8 in 10 diagnoses incorporated information from an adult other than a family member.

This is important information for healthcare providers, public health officials, and researchers who seek to determine how closely current practice matches with best practice for diagnosing ADHD. These findings provide new information on who is diagnosing ADHD and describes some of the features of those initial diagnostic visits. The estimates suggest that physicians who diagnose ADHD are largely using two recommended practices—behavior rating scales and incorporating feedback from adults other than family members—in their diagnosis of ADHD in children. This information will also inform future efforts to make sure that the diagnosis of ADHD reflects best practice recommendations.

Main Findings

Based on the parent’s report about their child’s ADHD diagnosis

  • About three-quarters of children with ADHD were diagnosed before age 9 and one-third of those by age 6;
  • A family member (which can include a parent) was usually the one first concerned about a child’s behavior, than someone from the child’s school or daycare;
  • A primary care physician (usually a pediatrician) first made the diagnosis for about half of the children;
  • Children with ADHD first diagnosed by a psychiatrist were more likely to be under 6 years of age than older;
  • Children with ADHD first diagnosed by a psychologist were more likely to be older than 6 years of age than under 6;
  • Healthcare providers nearly always had a conversation with a parent about their child’s behavior;
  • Healthcare providers used behavior rating scales or checklists to assess 9 in 10 children for ADHD; and
  • An adult outside of the family was usually involved in the diagnostic process.

About this Study

Researchers used data from the 2014 National Survey of the Diagnosis and Treatment of ADHD and Tourette Syndrome (NS-DATA)–a follow-up survey of the 2011-2012 National Survey of Children’s Health (NSCH). The NSCH examined health and well-being among children in the United States. The NS-DATA survey was conducted in 2014 to collect additional information about the diagnosis and treatment of ADHD and/or Tourette syndrome (TS) from parents who had previously reported that their child had ADHD or TS. Parents were asked whether they had ever been told that their child had ADHD and at what age; the type of healthcare professional who made the diagnosis; the first person who was concerned about the child’s behavior; the methods used to assess for ADHD; and whether information was sought from other individuals about the child and from whom (e.g. teachers, coaches, childcare providers, other family members etc.).
