Quizplus · Accepted Answer

In a double-blind control study, neither the treatment provider nor the research participants are aware of who is in the treatment group and who is in the control group. This is important for reducing bias and ensuring that the results are more accurate. Option A is incorrect because the treatment provider may know whether the treatment is effective, but they will not know which participants are receiving it. Option B is incorrect because it is important for the treatment provider and research participants to be aware of the research findings, but only after the study has been completed. Option D is incorrect because research participants must be aware that they are participating in a study and give informed consent.
