Consider the following statements about placebo studies. Which of them are right?
- A patient's belief that he or she is receiving treatment can play an important role in recovery even if the treatment is ineffective
- A placebo study involves two or three groups, depending on whether the researcher wants a control group
- If a control group is used, one group receives the treatment, another receives the placebo, and the control group receives nothing
- The decision about group allocation can be made through randomization
A1, 2 and 3
B2, 3 and 4
C1 and 3
DAll of the above ✓ Correct
Correct answer: (D) All of the above — All four statements about placebo studies are right, so the answer is all of the above.
Explanation
★All four statements about placebo studies are right, so the answer is all of the above.
★A patient's belief that he is being treated can aid recovery even when the treatment itself does nothing.
★A placebo study uses two or three groups, depending on whether a control group is wanted.
★With a control group, one gets the real treatment, one the placebo and the control group nothing.
★Group allocation can be decided by randomization to keep the groups fair and comparable.
★Since each statement is correct, all four together are right.
