Direct answer

Use the information.
Keep the conclusion proportionate.

Adult ADHD and autism questionnaires may support referral conversations, but diagnosis requires developmental, functional and differential assessment by appropriately qualified professionals.

Current difficulties must be understood alongside childhood and developmental history, education, work, relationships, coping strategies, sleep, mental health, physical health and possible overlapping conditions.

A useful next step

Record examples across more than one setting, gather relevant historic information where available and ask the GP or provider about the local referral and assessment pathway.

Four questions

Question. Context.
Limits. Action.

A complete decision needs more than a compelling label, score or explanation.

01

What is the real question?

Adult ADHD and autism questionnaires may support referral conversations, but diagnosis requires developmental, functional and differential assessment by appropriately qualified professionals.

02

What context changes the meaning?

Current difficulties must be understood alongside childhood and developmental history, education, work, relationships, coping strategies, sleep, mental health, physical health and possible overlapping conditions.

03

What must not be concluded?

A high or low screening score can mislead when treated as proof. Avoid services that offer a diagnosis solely from a brief questionnaire without appropriate clinical assessment.

04

What is the next proportionate action?

Record examples across more than one setting, gather relevant historic information where available and ask the GP or provider about the local referral and assessment pathway.

Practical sequence

Describe. Verify.
Decide. Review.

The sequence supports informed choice without turning wellbeing information into diagnosis or treatment.

01

Describe what is happening

Record observable experiences, timing, frequency and effect on everyday function. Separate what happened from the explanation you currently give it.

02

Verify the relevant information

Use current NHS, NICE, WHO, GOV.UK or another appropriate primary source. Check whether the information applies to the same population, intervention and purpose.

03

Choose a proportionate route

Record examples across more than one setting, gather relevant historic information where available and ask the GP or provider about the local referral and assessment pathway.

04

Agree how the decision will be reviewed

Define what improvement, persistence, deterioration, adverse effect or new information would change the plan or require referral.

Scope and safety

A high or low screening score can mislead when treated as proof. Avoid services that offer a diagnosis solely from a brief questionnaire without appropriate clinical assessment. iMetaWellness provides complementary wellbeing information and support within stated roles. It does not diagnose, prescribe treatment or replace a GP, NHS service or appropriately regulated professional. Use NHS 111 for urgent advice and call 999 where there is immediate danger.

In one sentence

What should the reader take from this guide?

Adult ADHD and autism questionnaires may support referral conversations, but diagnosis requires developmental, functional and differential assessment by appropriately qualified professionals.

Record examples across more than one setting, gather relevant historic information where available and ask the GP or provider about the local referral and assessment pathway.

What is the main boundary?

A high or low screening score can mislead when treated as proof. Avoid services that offer a diagnosis solely from a brief questionnaire without appropriate clinical assessment.

Uncertainty should lead to a clearer question or a more appropriate professional route, not a stronger unsupported claim.
