This Handbook examines core questions still remaining in the field of child maltreatment. It addresses major challenges in child maltreatment work, starting with the question of what child abuse and neglect is exactly. It then goes on to examine why maltreatment occurs and what its consequences are. Next, it turns to prevention, treatment and intervention, as well as legal perspectives. The book studies the issue from the perspective of the broader international and cross-cultural human experience. Its aim is to review what is known, but even more importantly, to examine what remains to be known to make progress in helping abused children, their families, and their communities.
