Quizplus · Accepted Answer

The balanced placebo design is a research method used to measure the role of expectancy in the effects of a drug. In this design, participants are randomly assigned to one of four groups: those who receive the drug and are told they are receiving the drug, those who receive the drug but are told they are receiving a placebo, those who receive a placebo but are told they are receiving the drug, and those who receive a placebo and are told they are receiving a placebo. By comparing the physiological and psychological effects of the drug in the four groups, researchers can tease apart the effects of the drug versus the effects of expectation. Marlatt and his colleagues specifically used this design to study the role of expectancy in alcohol's effects.
