Rating scale
Short answer
A rating scale is a standardized questionnaire where answers are given on a fixed range, such as Never to Very Often, so they can be counted and compared. Clinicians often use ADHD rating scales or symptom checklists during evaluations. Guidance from NICE says a diagnosis should not be made on rating scale data alone; scales are helpful added tools.
If you have ever rated a hotel from one to five stars, you have used a rating scale. In health care, the idea is similar: fixed answer options turn experiences into something that can be scored consistently.
What makes it a scale
- Every person sees the same questions in the same order.
- Answers come from a set range, often about frequency or severity.
- There are defined rules for turning answers into a score or outcome.
- It can be completed by the person, by someone who knows them, or by a clinician.
The ASRS v1.1 Screener is a short self-report rating scale. Each of its six questions offers five frequency options, from Never to Very Often, and certain answers fall in shaded boxes that are counted.
Where scales appear in ADHD care
Strengths and blind spots
Scales are quick, consistent and easy to compare over time. They also flatten detail. A five-point answer cannot explain why something happens, what it costs, or whether a recent life event is behind it.
Hypothetically, two people might both choose Often for the same question: one because of a chaotic month after a move, the other because it has been true since school. The scale records the same answer; only a conversation reveals the difference.
Scales also differ in who they are written for and what period they cover. A scale designed for children, or one asking about the past week, measures something different from an adult scale covering six months. Comparing scores across different scales rarely makes sense.
What a score does and does not mean
A score from a validated scale means something specific within that scale's rules, and nothing beyond it. A positive screen on the ASRS v1.1 means a fuller evaluation may help. It does not measure severity, and it does not diagnose. The Attention Profile in Part 2 uses statements and scores too, but it is our original non-clinical reflection, not a validated rating scale, and has no norms.
If a clinician gives you a scale to complete, it is reasonable to ask how they plan to use it and what else the evaluation will include.

Use the six-question rating scaleFrequently asked questions
Is the ASRS a rating scale?
Yes. It is a self-report scale with fixed frequency answers. The six-question screener is a short version used for screening.
Can a rating scale diagnose ADHD?
No. NICE says a diagnosis should not be made solely on rating scale data. Scales support a fuller clinical assessment.
Who fills in ADHD rating scales?
Depending on the scale, the person being evaluated, someone who knows them well, or a clinician.
