Research about child abuse and neglect is very complex methodologicall
y and ethically. There are not yet uniform research definitions of the
problem and the lack of prospective population-based research limits
the ability to make progress. To date researchers have been reluctant
to ask children directly about their maltreatment experiences because
of perceptions of ethical and legal responsibilities. This article beg
ins with a brief review of existing research about the scope and conse
quences of child abuse and neglect We address methodological considera
tions that are especially pertinent to research about child maltreatme
nt, including the definition of the problem, study design, and issues
of causality and bias. We conclude with a discussion of ethical and le
gal issues that arise in the course of carrying out such research, inc
luding issues related to subject recruitment, informed consent, confid
entiality, and reporting.
