Problematic sexual behavior (PSB) in children and adolescents is a significant public health problem. PSB is defined as harmful or developmentally inappropriate behaviors involving sexual organs or regions of the body exhibited by children or adolescents. PSB may be harmful to self or others or be abusive toward another child, adolescent, or adult. Adolescents, typically defined as children 12 years old or older, engaging in PSB can be vulnerable to formal court adjudication as their behaviors may be considered a sexual offense. PSB can result in significant negative consequences for all children and adolescents involved as well as their families. This article will describe sexual behavior in children, normative and problematic, and explore implications for forensic nursing practice.
