The regulations regarding informed consent are complex. Generally speaking, research subjects need to have sufficient information in the project in which they are being asked to become involved, and should voluntary agree to participate. The information given to the prospective subjects or the representatives needs to be in language they can understand. For those less than 18 years of age, the researcher must obtain the informed consent of parents or legal guardians.
The informed consent must include the following in sequential order and in language which the participants can understand:
In situations where participants will be deceived, items 1 and 2 are omitted and participants are told (on the signed form) that disclosure of the purpose and/or methodology could bias the outcome of the study. In this case, after the study is complete, each participant must be presented with a description of the purpose and methodology as carried out and this document must be signed by the participants "after the fact" in order to guarantee informed consent.
