People should only be asked to contribute to research that will give meaningful results. Design the research carefully and think about how you are going to use or analyse the results before you ask people to contribute to your work by being research participants.
If your project involves asking questions, you could try them first
on your friends or relatives to determine whether they appear
reasonable and acceptable, particularly from a stranger if that is how
it will be posed.
When you ask people to participate in your research, you need to tell them, in a language they can easily understand:
It is best to give this information to people in a written form and
to give them a chance to think about it and to ask any questions,
before they make any decisions.
Any research that involves bodily fluids or the ingesting of material (eg such as taking any kind of medication, ingesting substances, testing body tissue, saliva, skin scrapes, use of pain or deprivation of basic food or drink) should only be done under the guidance of a medical person. It is very unlikely that you will be doing such projects while still at school.
Any project should only involve minimal risk ie any adverse effect
should be very small, and the probability of that effect occurring
should be low. For instance, if one is asking people for
information, it should only be the sort of information it would be
safe, easily volunteered and appropriate to ask in an ordinary
conversation, or if you are asking people to exert themselves,
physically it should only be to a level that that person might do in
everyday life.
A parent or guardian needs to give their permission for anybody under 16, as well as the young person agreeing. The parent or guardian needs to have all the information that you would give a research participant. You should keep records of who has given consent and how it has been given whenever the research involves more than observation of individuals in their normal activities.
