What is a validated screener?
Short answer
A validated screener is a questionnaire that researchers have tested to check that it gives consistent results and that its results line up with a more thorough reference, such as a clinical interview, in a particular group of people. Validation is a process, not a stamp. It does not turn a screener into a diagnosis, and results depend on who was studied.
The word "validated" appears on many quiz websites, often with no explanation. In research it has a specific meaning. Understanding it helps you tell a carefully built questionnaire from one that only borrows the vocabulary.
Validation as a research process
Reliability
Validity
Comparing a screen with a reference standard
This is why a screener can perform one way in one group of people and differently in another. "Validated" always means validated somewhere, with someone.
An example: how the ASRS was studied
That pattern, developing a tool in one sample and then checking it in another, is a typical part of validation. The ASRS v1.1 screener used on this site comes from an earlier stage of the same research program.
What "validated" does not mean
- It does not mean the screener diagnoses anything.
- It does not mean every result is right for every person.
- It does not mean the tool works equally well in every group or setting.
- It does not mean a website's own rewording of the questions is validated too.
That last point matters. Changing wording, the number of answer options, or the scoring rule creates a different tool, which would need its own testing.
It also helps to remember what a screener is for. Even a carefully studied one is designed to sort people into "worth a closer look" and "probably not right now" on the basis of a few questions. That is useful, but it is a narrow job. The fuller picture, including history, daily life, and other explanations, still comes from a clinical evaluation.
How to check a claim of validation
- Look for the name of the published questionnaire.
- Look for a citation or link to the research.
- Check that the questions and scoring match the published version.
- Be cautious of any quiz that says it can give you a diagnosis or prove anything about you.

Is a validated screener the same as a diagnostic test?
No. A screener flags who might benefit from a fuller evaluation. Diagnosis needs a clinical assessment by a qualified professional.
Is the ADHDFalcon Attention Profile validated?
No. It is an original, non-clinical self-reflection tool, descriptive only, with no norms. It is not an ADHD measure.
Why do researchers keep studying screeners that are already validated?
Because validation is ongoing. Tools are checked in new groups and settings, and diagnostic standards change, which can lead to updated versions.
