Investigators encounter many legal and ethical issues when they conduct res
earch an partner abuse. Balancing abused women's rights to privacy with leg
ally mandated reporting requirements involves considerable thought and plan
ning. Failure to protect participants may result in escalation of abuse as
well as loss of children to protective services. Various perspectives on ma
intaining participant privacy while conforming to legal mandates to report
child abuse, homicidality, and suicidality are discussed. The role of confi
dentiality certificates in providing legal immunity for researchers and the
method of obtaining the certificates are presented. In addition, the autho
rs describe the strategies for participant protection that are implemented
in a federally funded study of abuse, women's self-care, and pregnancy outc
omes. The decision to clearly and specifically inform abused women of the l
imits of confidentiality allows participants to make informed decisions abo
ut disclosures, but may result in diminished recruitment.
