Everything you need to know about the Placebo Effect Psychology
What are medications for? The answer is simple - to alleviate the symptoms you are experiencing from the illness. But did you know that many of these medications carry some serious side effects? Wouldn't it be nice if you can reap the benefits without facing the blunt end of its respective side effects? Well, you can do that, and it's called the placebo effect psychology. This piece will try to provide a comprehensive overview of what it means and how it impacts on your psychology.
What is it exactly? Basically, to have a better understanding of this phenomenon. Professor Ted Kaptchuk of Harvard-affiliated Beth Israel Deaconess Medical Center provided an easy explanation - "The placebo effect is more than positive thinking — believing a treatment or procedure will work. It's about creating a stronger connection between the brain and body and how they work together,"
Although placebos won't be working on your cholesterol levels and neither will it shrink your tumor. It works on symptoms that your brain modulates. To that, Kaptchuk added, "They have been shown to be most effective for conditions like pain management, stress-related insomnia, and cancer treatment side effects like fatigue and nausea."
What are the advantages of using Placebo?
One of the major influences that Placebo has over psychological and medical studies is it allows researchers to minimize or eliminate the effect that your expectations have over the outcome. If researchers want to find a specific result, they will insert clues unknowingly which are known as demand characteristics - it leads the participants to anticipate what the researchers are trying to find. This has proven to change participant behavior.
However, to minimize the chances of such changes, researchers often conduct a double-blind study. This is a study where both the participants and the experimenters are oblivious of who's receiving the real or false treatment. By this method, the subtle biases that influence the study are minimized and researchers have a better viewing angle in discovering the effects of the drug and the placebo.
To make it simpler, let's break the process down with an expansive example - you participated in a volunteer program for a study that will conduct the effects of new headache medicine. After you take the pill, you find out that the headache of yours has quickly disappeared. However, you came to know that the medicine you were given was just a sugar pill.
According to an approximate understanding, 30% to 60% of the volunteers feel their pain dissipating after taking a placebo pill. In some studied cases, real medical treatment has benefited patients from the same placebo effect psychology. Researchers have exclaimed that the effectiveness of treatment has positive impacts if the physician recommending it does it under positive undertones.
What exactly causes the placebo effect?
One of the many theories suggests that if you have higher expectations on a pill to work, it's likely that it will. This can be described as a mind-over-matter instance where you believed so strongly that it happened. If the pill you were taking was to fix your headache, then you will be expecting it to work - which means that you had a conditioned response. (A conditioned response happens when you have an acquainted response over a specific stimulus). And, in this case, the stimulus was to take the medicine and feel better afterwards.
Another theory suggests that your brain tricks you into believing that the pill is doing its job. In some researches, the brain scans have found that people given a placebo pill will show the same brain activity as a person given the real treatment.
The only commonality these theories have is the combination of affirmative actions both from you and your doctor leading to a decreased level of stress. Anxiety and stress have adverse effects on your body, and it increases the focus of your symptoms largely. So, a reduction of stress may also reduce your physical symptoms.
How are they used?
Scientists are using a placebo to evaluate the effectiveness real medicines have over people. They are comparing the effects of placebo to that of the real medicine to find if the improvement was mentally induced or due to the active ingredients in the medication.
In a 2014 study conducted on migraine patients, concluded that the placebos were still effective even when the patients taking them were aware of taking a placebo. The outcome was quite surprising since the placebo consumption lessened the migraine as opposed to real medicine. The study concluded on the note that 50% of that medicine's effect was because of the placebo effect.
Placebo does offer some of the best alternatives and that too without any side effects. Therefore more researches are being conducted to sort the complexity placebo has over the human brain and neurotransmitters producing the effect. This, perhaps, requires more time but the placebo effect cannot be ruled out as a single phenomenon. So, it is more of an accumulated result due to biochemical, anatomical and psychological factors. So, now to wrap this once and for all, let’s see what else Kaptchuk had to add - "Even if they know it's not medicine, the action itself can stimulate the brain into thinking the body is being healed."
