Rates of psychotropic medication use in children with ASD compared to presence and severity of problem behaviors

There is a scarcity of research on the relationship between presence of problem behaviors and psychotropic medication use in children with autism spectrum disorder (ASD). Participants in the current study were children and adolescents ages 3-17 years who were sorted into four groups: ASD on psychotropic medication (N = 100), ASD not on psychotropic medication (N = 147), typically developing on medication (N = 48), and typically developing not on medication (N = 168). A one-way multivariate analysis of covariance (MANCOVA) was conducted to determine the relationship between medication use and rates of internalizing and externalizing behaviors. Post hoc analyses revealed that children with ASD on psychotropic medication evinced significantly more externalizing behaviors than children with ASD not on medication. However, the two groups did not significantly differ on rates of internalizing behaviors. These results suggest that psychotropic medications may often be prescribed to manage externalizing behaviors. Implications of these findings are discussed in relation to the existing literature.
