Ethical considerations in qualitative research with vulnerable groups: exploring lesbians' and gay men's experiences of health care--a personal perspective.

It is rare to find honest accounts of the difficulties and dilemmas encountered when conducting sensitive research with vulnerable research populations. This account explores some of the ethical issues raised by a qualitative interview study with lesbians and gay men about their experiences of nursing care. There is tension between the moral duty to conduct research with vulnerable and stigmatized groups in order to improve care, and the inevitable lack of resources that go with such a venture. This increases the risk of harm during the process of research. The risk of harm to both the researchers and the researched is explored and the need for a support structure for both groups is raised. There is a pressing need to develop further understanding about the ways in which the dissemination of research can potentially harm already vulnerable research populations.
