Researches involving the children have become omnipresent in the field of social sciences, which is attributed to the emphasis on child rights and seeing children as experts for childhood. Such research entails special ethical questions before, during and after the research. In this paper, the focus is on ethical challenges in the research on child abuse and neglect as a particularly sensitive research topic with vulnerable population, which requires much reflection and increased sensitivity of researchers for ethical procedures. The paper presents ethical aspects of research with children, reflecting on socially sensitive topics, then the ethical aspects of research on child abuse and neglect and than the ethical dilemmas that emerge in the implementation of these research. The ethical dilemmas described above relate to the issue of consent or willingnes for participation, informed consent, disclosure and confidentiality of data, risk management and child welfare in the research process and the conflict of professional role of researchers and helper. Finally, based on the literature, a proposal for guidelines for ensuring ethical conduct in research on child abuse and neglect was presented. The emphasis is on good and detailed preparation by researchers to conduct such research and constant reflexivity on ethics in research. That is why it is very desirable for researchers to report about the dilemmas they encountered and how they were solved. This would help to create clearer ethical guidelines for dealing with specific situations that researchers may encounter while conducting research on child abuse and neglect.
