Children and youths are valuable informants, and are entitled to be heard, also in the context of research. This also applies to Internet research on children and youths. Such research raises special challenges because it is part of children's activities, which are often beyond the control of adults, and the boundaries between the worlds of children and of adults are not very clear. However, this does nothing to diminish the requirement to obtain parental consent for children's participation in research, even though this may prove more difficult in practice (point 12). Here it is also important to verify the respondents' actual biological age. The children themselves must also grant informed consent to participate in the research.

In some cases, a better way to respect children's right to protection may be to use established research methods that do not involve the Internet as a research tool, even when collecting data on the Internet.
