Researchers extract key elements in youthful blood to make a pill that is called the Fountain of Youth. The researchers have found increased biomarkers of health in adults over 35 after taking this pill. They want to run a double blind, randomized controlled experiment to test the validity of these findings.What is an example of the placebo effect?Hint, displayed belowA participant in the treatment group takes a Fountain of Youth pill and reports feeling more and more beautiful every day that she takes it.A participant in the control group takes a sugar pill but reports feeling more and more beautiful every day that she takes it.A participant in the control group takes a Fountain of Youth pill and reports feeling more and more beautiful every day that she takes it.A participant in the treatment group takes a sugar pill but reports feeling more and more beautiful every day that she takes it.

To study the efficacy of a specific treatment for a particular psychiatric disorder, researchers will often employ a double-blind, placebo-controlled experiment. A double-blind study means that neither the participants nor the researchers know which participants are receiving the placebo, and which participants are receiving the treatment. These studies are designed to compare the results of the introduced treatment with that of a placebo on two groups of randomly selected patients.In the field of psychiatric drug development – also known as psychopharmacological drug development – placebo studies pose a significant problem in that they often result in negative findings. These are trials in which researchers have failed to demonstrate the superiority of the treatment over the placebo condition, and therefore pose a range of issues surrounding the validity of clinical drug development trials. The larger the placebo response, the more difficult it is to prove that an experimental treatment is effective.Describe what is meant by the term ‘placebo problem’ and explain how this can be problematic for psychopharmacological drug developers.

From the key study by Grant et al. (2008) on treating gambling disorder with drugs and placebo:(a) Explain what is meant by a double-blind, placebo-controlled trial as used in this study. [4](b) Suggest one effect if a double-blind trial had not been used in this study. [2](c) Explain two strengths of conducting placebo-controlled trials in studies of gambling disorder.[4
