Editorial: Shifting the Landscape of Child Psychiatric Epidemiology

The results of recent surveys that show high levels of symptoms of anxiety and depression have generated widespread concern about the mental health of US youth. Although such increases and their causes require immediate action, these symptoms alone do not indicate an epidemic of mental disorders in the US because they do not reflect mental disorders that are characterized by protracted duration and educational or social impairment. Unfortunately, there are no recent comparable data on the full range of common mental disorders. (e.g., Anxiety, Attention Deficit Hyperactivity Disorder, Major Depression, etc.) in nationally representative samples of US youth to provide a baseline for the reported increased distress in recent surveys. Therefore, we must rely on indirect information derived from surveys of subsets of symptoms and behaviors or of restricted age groups, and web-based samples with unknown biases and limited generalizability. This editorial describes how the findings from a recent report of prevalence of mental disorders in 9-10-year-old youths from the ABCD study can contribute to the national profile of mental disorders in youth. We highlight the need to address the lack of systematic data on youth emotional and behavioral disorders in the US through concerted efforts to coordinate the multi-agency sources of data on youth mental health. This will require harmonization of sampling and methods, informed application of internet-based tools based on systematic sampling and non-probability sampling methods and promotion of efforts to bridge the gap between population-based research and interventions at both the societal and individual levels.
