Child abuse raises public passion and professional concern, which demands a
careful review of the evidence of its longer term psychosocial impact. The
field is controversial, compounded by inadvertent 'professional iatrogenes
is' involving all disciplines, including general practitioners and psychiat
rists. Definitions and the prevalence of 'abuse' are explored and the psych
osocial consequences of the different types of abuse, including its extreme
s, a murdered child, are reviewed. Evidence is presented for the need for r
ediscovering the central importance of the psychiatric and poverty dimensio
ns in the child protection interface, which should lead to an integrated, e
vidence-based treatment/policy approach that is necessary for child protect
ion. New evidence is offered in considering the appropriateness of a 'Megan
's Law' for Britain.
