The action of a drug or psychological treatment that is not attributable to any specific operations of the agent. For example, a tranquilizer can reduce anxiety both because of its special biochemical action and because the recipient expects relief. See placebo.
(n) a therapeutic effect observed from an inactive substance (i.e., placebo) which presumably occurs because the patient "believes" that it will occur
The effect a patient’s expectations (or the expectations of medical personnel, as communicated to the patient) can have on the efficacy of a medication or other medical intervention. Positive expectations (the placebo effect) can lead to positive results, negative expectations (the nocebo effect) can lead to negative results. See also, "experimenter effect" and "Perky effect."
The actual medical or psychological benefits of a treatment administered to a patient who believes it has therapeutic powers even though it actually has none.
Effect of medication that has no proven value giving beneficial result.
The phenomenon of seeing an improvement while taking a placebo.
positive effect after an inactive treatment that should have no effect, but is administered in a way that makes the person believe they're receiving an active treatment.
much as in scientific studies where some patients show improvement even though they are getting a placebo (a sugar pill), participants in a control group in a social capital evaluation may also show improvement just because they sense that they are part of some important study.
Improvement in outcome that is consistent but not due to any treatment or non-treatment administered. This is only a factor for human beings and possibly animals where psychology of care can affect outcome. See also Placebo.
any effect that seems to be a consequence of administering a placebo; the change is usually beneficial and is assumed result from the person's faith in the treatment or preconceptions about what the experimental drug was supposed to do; pharmacologists were the first to talk about placebo effects but now the idea has been generalized to many situations having nothing to do with drugs
a beneficial response to a substance, device, or procedure that cannot be accounted for on the basis of pharmacologic or other direct physical action
A positive or therapeutic benefit resulting from the administration of a placebo to someone who believes the treatment is real.
If you believe something will make an improvement, it will make an improvement (usually). A scientific fact so well documented that trials of new drugs are always blind-tested vs. a placebo (something with no "real" effect). The fact that a significant percentage of people taking the placebo are always cured is a rather remarkable proof of the power of the brain. It follows that one is often happier as a stupid believer than as a wiseacre cynic.
The apparently beneficial result of a medication or other therapy that has no proven value or effect in the management of a medical problem. The apparent benefits occur because of an individual's expectation that the therapy will help.
An apparently beneficial result of therapy that occurs because of the patient's expectation that the therapy will help.
The placebo effect is the measurable, observable, and/or felt improvement (or decline) in health, which can not be attributed to the treatment. It is often seen in people who are receiving a placebo treatment in a clinical trial. The reason why an inert substance or fake therapy would produce an effect is not known. Positive effects from a placebo are believed by some to be psychological (i.e. due to belief in the treatment), while others believe that it is due to an illness or injury taking its natural course. Some people believe that the placebo effect is due to the fact that showing attention and care to a patient itself triggers reactions in the body that promotes healing. Some people believe that as long as a treatment is effective, it doesn't matter if the effect is due to the placebo effect or otherwise.
Improvement due to expectation rather than the treatment itself; can occur when participants receive a treatment that they consider likely to be beneficial.
The phenomenon where an otherwise worthless intervenÂtion in a study nevertheless induces an improvement in the patient’s conÂdition or perception of their condition, perhaps due to the expectations of the participants in the study.
the effect on patient outcomes (improved or worsened) that may occur due to the expectation by a patient (or provider) that a particular intervention will have an effect. The placebo effect is independent of the true effect (pharmacological, surgical, etc.) of a particular intervention. To control for this, the control group in a trial may receive a placebo.
A situation where people experience some change or improvement from an empty, fake, or ineffectual treatment.
A psychological phenomenon noted by researchers in which patients who receive a phony medication feel better and report improvements in subjective symptoms such as pain or depression.
A physical or emotional change, occurring after a substance is taken or administered, that is not the result of any special property of the substance. The change may be beneficial, reflecting the expectations of the participant and, often, the expectations of the person giving the substance.
Used to describe improvement in the condition of patients who think they are being treated, but are in fact getting a dummy treatment.
a tendency for a beneficial effect to occur if a person is expecting that a treatment will be therapeutic. A placebo is a neutral treatment (such as an inactive pill) that may nevertheless promote healing because of the hope and confidence placed in it.
The tendency for an ineffectual drug or treatment to improve a patient's condition because he or she believes in its effectiveness.
A beneficial effect of a medical technology that cannot be attributed to properties of the technology itself. Often considered psychologically-engendered well-being or improvement in a condition brought on by the belief of the patient that the technology itself is beneficial.
a change (e.g., a reduction in symptoms) that is attributable to the treatment process itself as opposed to the therapeutic value of the agents or therapies used, most likely due to the expectations of the patient.
Healing effects which are based on the person's own self-healing capacity, but which is triggered by the belief that they are receiving an active medication.
The changes that occur after a person takes a placebo. People often feel effects from placebos, in part because of their expectations about how a drug or device will work.
Improvement of a condition experienced by a patient who believes a treatment has been administered even if the treatment was not actually done.
Beneficial effect observed in some patients when they believe they have received a treatment but in fact have not.
The positive reaction to a pharmacologically inactive or neutral substance by a recipient who believes it will work.
the phenomenon that a patient's symptoms can be alleviated by an otherwise ineffective treatment, since the individual expects or believes that it will work. Some people consider this to be a remarkable aspect of human physiology; others consider it to be an illusion arising from the way medical experiments were conducted.
healing that results from a person's belief in a treatment that has no medicinal value
Placebo Effect was a German dark electro band.
