When evaluating clinical research, you cannot always take the results at face value. Even well-designed studies on how exercise treats depression can be influenced by hidden flaws. These flaws are known as biases, and they can make a treatment appear more or less effective than it truly is.
For your psychology entrance exams, simply knowing the results of a study is not enough. You must be able to critically analyze how the study was conducted. If a study claims that yoga is just as effective as an SSRI for major depressive disorder, you need to ask: Were the participants aware of the treatment they received? Did the researchers have a specific outcome in mind? Are we only seeing the positive results?
This lesson explores the common biases that affect clinical psychology research. You will learn how to identify these flaws, understand the unique challenges of exercise studies, and build the critical thinking skills required to evaluate research effectively on your exam.
