Child neglect (also called psychological abuse) is commonly defined as a failure by a child's caretaker to meet a child's physical, emotional, educational, or medical needs.
Child maltreatment can be defined either using abusive or neglectful adult behaviours (e.g., the definition of child physical abuse would comprise parental behaviours such as hitting or shaking), or by the harm caused to the child as a result of such behaviours (e.g., child physical abuse would be indicated if the child displayed physical symptoms such as bruising or swelling).
