What is the difference between blinding and masking?
“Masking” (or “blinding”) refers to the steps taken to ensure that all persons involved in a trial are unaware of the type of treatment that each participant receives. Blinding can also be extended to include other personnel and data analysts.
What is the difference between masking and blinding in clinical trials?
In addition, masking is sometimes used to describe how treatments are made indistinguishable [18, 19, 25, 26], whereas blinding usually indicates which groups are unaware of treatment assignment [1,2,3,4,5,6].
What is the blinding method?
Blinding, in research, refers to a practice where study participants are prevented from knowing certain information that may somehow influence them—thereby tainting the results.
What does masking in a study mean?
Blinding or masking (the process of keeping the study group assignment hidden after allocation) is commonly used to reduce the risk of bias in clinical trials with two or more study groups.
Are all RCTs blinded?
Although blinding may not be feasible in all RCTs, it is especially important that it be implemented when the outcome is subjective (e.g., pain or energy level). The nature of the intervention determines the level of blinding possible.
What type of bias is prevented by masking?
The goal of masking is to prevent ascertainment bias. In contrast to allocation concealment, masking cannot always be incorporated into a randomized controlled trial.
What is the difference between blinding and double blinding?
In a single blind study, the participants in the clinical trial do not know if they are receiving the placebo or the real treatment. In a double-blind study, both the participants and the experimenters do not know which group got the placebo and which got the experimental treatment.
What is blinded endpoint?
The benefits associated with a strict randomization procedure are maintained and the incorporation of clearly defined, blinded endpoints helps to eliminate bias by allowing objective comparison of therapies and evaluation of the study results by an independent body.
What is a masked design?
Typically, a study design in which the investigator, but not the subject, knows the identity of the treatment assignment. Occasionally the subject, but not the investigator, knows the assignment. Sometimes called “single-blind design.”
What are types of blinding?
Types of blinding
| Type | Description |
|---|---|
| Single blind or single-masked | Only the participant is unaware of the treatment they receive |
| Double blind or double-masked | The participant and the clinicians / data collectors are unaware of the treatment the participant receives |
What is triple blinding?
[trip´l blind] pertaining to a clinical trial or other experiment in which neither the subject nor the person administering treatment nor the person evaluating the response to treatment knows which subjects are receiving a particular treatment or lack of treatment; see also placebo.
What are blinded studies?
Listen to pronunciation. (BLINE-ded STUH-dee) A type of study in which the patients (single-blinded) or the patients and their doctors (double-blinded) do not know which drug or treatment is being given. The opposite of a blinded study is an open label study.
Which is better, blinding or masking in trial design?
In contrast, the term “masking” is defined as “to cover in order to conceal, protect, or disguise.” We can see that the word masking in itself is a better description of what we intend to do in a trial—no matter what specialty is involved. Thus we suggest that the term blinding should be avoided in trial design.
Which is better, blinding or masking eye care?
Masking is better than blinding. As a medical term blindness does not really have a strict definition, but it has a much greater resonance in its sociocultural meaning. This common meaning is emotive enough outside eye care services, but within them the word is rarely used by practitioners and dreaded by patients.

Which is less emotive, blinding or masking?
Thus the word blinding is deeply ingrained in the language of trial design and evidence based medicine. 6 To replace this word with a less emotive one requires a term that conveys the same obvious meaning of concealment of treatment. What is an alternative?
