Background: While research has largely focused on the relationship between sensory processing patterns and internalizing behaviors (e.g., anxiety, depression) in children with autism spectrum disorder or attention deficit hyperactivity disorder, this relationship is not fully understood among the general population or across development.

Method: This scoping review addressed the following research question: How are sensory processing patterns associated with internalizing behaviors (e.g., anxiety, depression) among children with various conditions as well as typically developing children from birth to 22 years of age?
