Variability in Prevalence, Clinical Identification, and Treatment of ADHD in Children (1 of 5)

The information in this slide lists conclusions on the variability in prevalence, diagnosis, and treatment of ADHD in children associated with potential moderating factors. For these conclusions, the literature was searched using the methodology of a systematic review; however, the selection of papers for inclusion was not subject to the same constraints as the rest of the report. Other relevant papers were added via peer review feedback. These findings were included to provide context, and any studies considered pertinent to the topic of variability in ADHD prevalence, diagnosis, and treatment were included.


  • Cultural differences influence how ADHD is understood and treated in different countries.
  • After taking into account differences in research methodologies between countries, the underlying prevalence does not appear to vary much among countries.
  • Rates of diagnosis vary considerably due to cultural context, access to local health care services, and providers available in the area.
  • There are significant regional variations in clinical identification across the United States.
  • Rates of treatment vary considerably due to location and access to health care providers—internationally, regionally, and even within the same community.
