Publisher: Pinnacle Blooms Network / Bharath Healthcare Laboratories Private Limited

The ADI-R (Autism Diagnostic Interview–Revised) is a detailed, structured interview a trained clinician conducts with a parent or caregiver, exploring a child's development, communication, social relating and repetitive behaviours. It is used as one part of a fuller autism assessment, never alone, and Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional. under qualified clinician care.

*The ADI-R is a careful, in-depth conversation with you about your child's development — one of the most trusted tools clinicians use to understand autism.*

## In short
The **Autism Diagnostic Interview–Revised (ADI-R)** is a detailed, structured interview that a trained clinician conducts with a parent or main caregiver. It gently explores your child's early development, communication, social relating and any repetitive behaviours or special interests. It is not a test *for* your child to sit — it draws on your everyday knowledge of them, and it is used as one part of a fuller assessment, never on its own.

## What the ADI-R actually involves
- **It's a conversation with you.** A trained interviewer asks open questions about your child's history and current behaviour — how they communicate, play, relate to others and respond to changes in routine.
- **It covers key developmental areas.** Questions group around social interaction, language and communication, and repetitive or restricted behaviours and interests, including a look back at the early years.
- **It is standardised.** Every family is asked in a consistent, research-validated way, so the picture that emerges is reliable and comparable.
- **It pairs with direct observation.** Clinicians usually combine the ADI-R (your account) with a play-and-interaction observation of the child, plus developmental and medical history, to form a rounded understanding.
- **It takes time — and that's a good thing.** A thorough interview honours the detail of your child's story rather than rushing to a label.

Think of it as the clinician borrowing your years of close observation, and organising it into something clear and useful.

## When it's used
The ADI-R supports the assessment of children where autism is being considered, alongside other tools. It is administered by clinicians with specific training. A diagnosis is never made from any single interview or questionnaire — it comes from a qualified clinician weighing the whole picture together.

## The Pinnacle way
AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional — never from an online form or a single questionnaire. Our clinicians use structured, internationally recognised approaches as part of a warm, child-friendly [autism assessment](/autism-therapy), then build a plan around your child's strengths. Learn how our own clinician-administered [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) brings this together, or start at our [home of child development](/).
