Recently the U.S. Preventive Services Task Force issued a formal recommendation that adolescents and children as young as 8 should be screened for anxiety.1 The advice was based on a review of the research that concluded that anxiety disorders were common in youth (prevalence around 8%), screening was not overly burdensome or dangerous, and treatments were available and effective.
While pediatricians fully appreciate how common clinically significant anxiety is and its impact on the lives of youth, the reception for the recommendations have been mixed. Some are concerned that it could lead to the overprescribing of medications. Arguably, the biggest pushback, however, relates to the question of what to do when a child screens positive in a time when finding an available child and adolescent psychiatrist or other type of pediatric mental health professional can feel next to impossible. The hope of this article is to fill in some of those gaps.

Screening for anxiety disorders
The recommendations suggest using a rating scale as part of the screen but doesn’t dictate which one. A common instrument that has been employed is the Screen for Child Anxiety and Related Disorders, which is a freely available 41-item instrument that has versions for youth self-report and parent-report. A shorter 7-item rating scale, the General Anxiety Disorder–7, and the even shorter GAD-2 (the first two questions of the GAD-7), are also popular but focus, as the name applies, on general anxiety disorder and not related conditions such as social or separation anxiety that can have some different symptoms. These instruments can be given to patients and families in the waiting room or administered with the help of a nurse, physician, or embedded mental health professional. The recommendations do not include specific guidance on how often the screening should be done but repeated screenings are likely important at some interval.
Confirming the diagnosis
Of course, a screening isn’t a formal diagnosis. The American Academy of Pediatrics has expressed the view that the initial diagnosis and treatment for anxiety disorders is well within a pediatrician’s scope of practice, which means further steps are likely required beyond a referral. Fortunately, going from a positive screen to an initial diagnosis does not have to overly laborious and can focus on reviewing the DSM-5 criteria for key anxiety disorders while also ensuring that there isn’t a nonpsychiatric cause driving the symptoms, such as the often cited but rarely seen pheochromocytoma. More common rule-outs include medication-induced anxiety or substance use, excessive caffeine intake, and cardiac arrhythmias. Assessing for current and past trauma or specific causes of the anxiety such as bullying are also important.
It is important to note that it is the rule rather than the exception that youth with clinical levels of anxiety will frequently endorse a number of criteria that span multiple diagnoses including generalized anxiety disorder, social anxiety disorder, and separation anxiety disorder.2 Spending a lot of effort to narrow things down to a single anxiety diagnosis often is unnecessary, as both pharmacologic and nonpharmacologic treatments don’t change all that much between individual diagnoses.
