What is the main purpose of a clinical trial?

To evaluate the effectiveness of a treatment
To measure the potential side effects of a treatment
To prove the efficacy of a psychological treatment
To analyze the results of a psychological experiment

The correct answer is: To evaluate the effectiveness of a treatment

A clinical trial is a research study conducted to determine the effectiveness of a treatment. The main purpose of a clinical trial is to evaluate whether a treatment is safe and beneficial for a specific condition or disease. Other options, such as measuring potential side effects and analyzing results of an experiment, may also be part of a clinical trial, but they are not the main purpose. Furthermore, option C, proving the efficacy of a psychological treatment, is specific to psychological treatments and may not apply to all clinical trials. Thus, the main purpose of a clinical trial is to evaluate the effectiveness of a treatment, making option A the correct answer.
