How Anxiety Can Lead to Disruptive Behavior 3/21/2019

It is common for children and families to present to their primary care providers with concerns about behavioral problems and/or wanting to rule out ADHD. The typical presenting problem is severe temper tantrums or disruptive behavior in school. In some of these cases, the appropriate diagnosis is ADHD or another disruptive behavior disorder and treatment involves medication and/or behavioral therapy and parent management training. But in many of these cases, the underlying diagnosis leading to the behavioral problems is something else. A not uncommon reason behind disruptive behavior is underlying anxiety. Are there signs that this might be the case that can be elicited in the primary care office?

A child who appears to be oppositional or aggressive may be reacting to anxiety—anxiety he may, depending on his age, not be able to articulate effectively, or not even fully recognize that he’s feeling. Anxiety is based on the body’s physiological response to a threat in the environment, as a response to maximize the body’s ability to either face danger or escape danger. Some children show their anxiety by becoming quiet, shrinking away from situations that make them anxious, and having trouble separating from their parents. These symptoms of anxiety are easy to detect for most providers.

However the above symptoms are not the only way that anxiety manifests itself. Other children react with an overwhelming need to break out of an uncomfortable situation, which can be misread as anger or opposition. What people on the outside see is intense anger that is out of proportion to the situation, property destruction, elopement and aggression. In this way, anxiety can be a great masquerader.

Anxiety can present in the school setting as disruptive behavior. A child might be find the academic work hard or become frustrated if he can’t do it perfectly. A child might have a hard time taking feedback or criticism from the teacher or peers. A child might be overwhelmed with the noise level in the classroom or a crowded classroom.

When a child presents with disruptive behavior, it is important to ask screening questions in other mental health areas as well, including depression, anxiety, OCD and ASD. If any of these screening questions are positive, consider asking more detailed questions or obtaining screening questionnaires to elicit more details. Referral for a more thorough diagnostic evaluation with a psychologist could be helpful as well in cases that are diagnostically confusing.

This distinction is important to make sure a child has the right diagnosis. But it also impacts treatment. The therapy approach for anxiety is different than the therapy approach for disruptive behavior disorders. CBT is helpful for anxiety while behavioral therapy and/or parent management training is helpful for disruptive behaviors. Psychotropic medication, if being considered, would be different as well. The SSRIs would be first line medication treatment for anxiety which the stimulants or non-stimulants like the alpha agonists (guanfacine and clonidine) or atomoxetine would be first line medication treatment for ADHD and other disruptive behavior disorders. If one is considering medication treatment for the behavioral dysregulation that is seen with anxiety, the alpha agonists can be helpful specifically for that. The stimulants can actually make the anxiety worse in these clinical situations.

It is our hope that this primer on how anxiety can lead to disruptive behavior and masquerade as a disruptive behavior disorder is helpful.
