• The research must be well designed.
• The investigator must give a rational explanation and appropriate justification for the use of deception.
• All protocols involving deception must be thoroughly reviewed by CPHS weighing those elements against the risk/benefit correlation for the subject.

When deception is part of the research design, the deception must be absolutely necessary to the research and participants must be thoroughly debriefed after their participation is complete. For such protocols we suggest the following language be added to the consent form:

"We are going to tell you the overall intent of the research in which you are being asked to be a subject but not all of the details because this might influence the way in which you participate. Once your participation is complete, you have every right to know all of the details and the research physician or staff will inform you of the details."

and/or

"The research may contain elements of deception, but the CPHS reviews all research protocols to ensure that you are informed of any part of the research that might cause you harm. Once your participation is complete, the researcher will inform you of the details."
