Researchers looked at the impact of a new medication on the behaviour of cats with anxiety. Cats were randomly assigned to received either the medication or an inactive substance, and their behaviour was observed Statement 1 A placebo was not used in this study. (true or false) Statement 2 A control group was used in this study. (true or false) Statement 3 Blinding was used in this study. (true or false)

Researchers looked at the effect of a new medication on the behaviour of horses with anxiety. Horses were randomly assigned to received either the medication or an inactive substance, and their behaviour was observed. The researchers collecting and analysing the data dit not know whether the horses had received the medication or the inactive substance. Use the information about the study to decide if each of the following three statements are TRUE or FALSE. Statement 1 A placebo was not used in this study. Statement 2 Blinding was not used in this study. Statement 3 A control group was not used in this study.

Few of the patients undergoing treatment for phobic disorder agree to participate in a clinical trial of a new antidepressant medication. The patients are randomly divided into two groups. Both groups receive pills to be taken on a daily basis, but only one of the groups receives pills with the newly produced active ingredients. The other group's pills contain no active ingredients. In this study, the pills that do not contain any active ingredients are said to beMultiple Choiceipsatives.normatives.nocebo.placebos.

You design a study to evaluate the effect of a new treatment for an anxiety disorder.  In the study, one group of participants (Group 1) receive the new treatment for 1 hour per week, for 8 weeks. Another group of participants (Group 2) receive nothing for 8 weeks, they are waiting to receive the treatment later.  Before the treatment and after the treatment, you measure the level of anxiety in both groups.  At the end of the treatment, you find that both groups improved slightly, and to the same degree.  What is your conclusion? Group of answer choicesboth groups got better as a result of placebo effectsthis is not possible, there was a mistake in the designthe treatment was effective for Group 1the treatment was effective for both groupsboth groups got better as a result of time passing

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.

The control group in a study looking at the effects of a drug on behavior would probably be administered a to make them think they were getting the drug.
