Autism Diagnostic Interview-Revised
Should My Child Have an ADI-R Assessment?
The ADI-R is a structured, in-depth interview a trained clinician conducts with the parent — covering early development, communication, social connection and behaviour patterns — to help inform an autism evaluation. It takes roughly 1.5–2.5 hours, is usually paired with a direct child assessment, and is one tool within a fuller picture. Whether your child needs it is decided by a qualified clinician, never from an online form.
Wondering if the ADI-R is the right step for your child? Here's what it actually is — and how it fits into getting clear, caring answers.
In short
The Autism Diagnostic Interview-Revised (ADI-R) is a structured, in-depth interview that a trained clinician conducts with you, the parent or carer — not directly with your child. It explores your child's early development, communication, social connection and patterns of behaviour to help inform an autism evaluation. Whether your child needs it is a decision a qualified clinician makes after meeting you both; it is one tool within a fuller assessment, never a stand-alone verdict.What the ADI-R involves
The ADI-R is a detailed, gentle conversation — typically 1.5 to 2.5 hours — guided by a clinician who asks you about your child:- Early history. Questions about your child's development in the first years — first words, gestures, how they played and connected.
- Communication. How your child uses and understands language, gestures and conversation, now and earlier.
- Social connection. Eye contact, sharing enjoyment, friendships, and responding to others.
- Patterns and interests. Repetitive behaviours, routines, and focused interests.
Because it draws on your knowledge of your child across their whole life, your everyday observations are exactly what makes it valuable. It is usually paired with a direct play-and-interaction assessment of the child (such as the ADOS) and a developmental review, so the clinician sees a complete picture rather than a single snapshot.
Should your child have one?
The ADI-R is most useful when there are existing developmental concerns and a clinician is working toward — or carefully ruling out — an autism profile. It is not a screening tool you request on a whim, and not every child needs it. The right starting point is a developmental check: from there your clinician decides which assessments genuinely add clarity for your child. There is no harm in asking; the answer is always individual.The Pinnacle way
A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under the care of a qualified clinician — never from an online form or a single questionnaire. Our clinicians use structured tools like the ADI-R alongside our own clinician-administered AbilityScore® to understand your child against their own baseline, then build a practical plan. Backed by 4.95 lakh+ families served across 70+ centres, we turn assessment into action through autism support and therapy. You can read how our measure works here: what the AbilityScore is and how it's calculated.Trusted sources

What to watch
Watch for whether developmental concerns are ongoing — differences in communication, social connection, play or repetitive routines — as these are what make a structured tool like the ADI-R useful. Note your child's early history (first words, gestures, eye contact) since the interview draws on your memories. If concerns are new or unclear, start with a general developmental check rather than requesting a specific tool.
Try this at home
Before any assessment, jot down small everyday observations — when your child first spoke, how they play, how they respond to their name. These real-life notes make the parent interview far richer and help the clinician see your child clearly.

Frequently asked
Is the ADI-R done with my child or with me?
The ADI-R is conducted with you, the parent or carer — not directly with your child. The clinician asks about your child's development, communication, social connection and behaviour, drawing on your detailed knowledge across their whole life.
How long does an ADI-R take?
It is typically a 1.5 to 2.5 hour structured interview. It is usually combined with a direct play-and-interaction assessment of the child and a developmental review for a complete picture.
Does an ADI-R give a diagnosis on its own?
No. The ADI-R is one informative tool within a fuller evaluation. A diagnosis is formed by a qualified clinician who weighs multiple sources of information — never from a single questionnaire or interview.
How do I know if my child needs an ADI-R?
That decision is made by a clinician after meeting you and your child. The best starting point is a general developmental check; from there your clinician advises which assessments genuinely add clarity for your child.
