It is not a test the child sits and is never used alone. It explores a child's developmental history across three areas: communication and language, reciprocal social interaction, and restricted or repetitive behaviours and interests. Clinicians often pair it with a play-based child observation to form one rounded understanding.","answer_md":"*A careful, structured conversation with parents that helps clinicians understand a child's developmental story — that is the heart of the ADI-R.*\n\n## In short\nThe **Autism Diagnostic Interview-Revised (ADI-R)** is a structured, in-depth interview that a trained clinician conducts with a parent or main caregiver to gather a detailed developmental history of a child being assessed for autism. It is not a test the child sits, and it is never used alone — it is one trusted piece of a wider assessment. The interview gently explores three core areas: communication and language, social interaction, and repetitive or restricted behaviours and interests.\n\n## What the ADI-R assesses\nBecause you, the parent, know your child best, the ADI-R draws on your everyday observations. A trained interviewer asks open, structured questions about both your child's current behaviour and how they developed in their early years. The conversation focuses on three domains:\n\n- **Communication and language** — how your child uses words, gestures, and back-and-forth conversation, and how language unfolded over time.\n- **Reciprocal social interaction** — how your child shares attention, plays with others, makes eye contact, and responds to people emotionally.\n- **Restricted, repetitive behaviours and interests** — patterns such as intense focused interests, routines, or repetitive movements.\n\nThe interview is detailed and can take a couple of hours, because its strength lies in capturing the full developmental picture rather than a single snapshot. Clinicians often pair it with a play-based, child-facing observation (such as the ADOS) so that what is reported and what is seen come together into one rounded understanding.\n\n## When it is used\nThe ADI-R is used by qualified clinicians as part of a comprehensive autism assessment, usually when there are already questions or observations worth exploring carefully. It is a clinical tool, not a screening checklist or an online quiz — and a warm, unhurried conversation with the right professional is exactly where it belongs.\n\n## The Pinnacle way\nThis is general information, not a diagnosis — a clinical [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care, never from an app or form. Our team brings together structured tools like the [ADI-R](/adi-r) alongside play-based observation and, where helpful, [autism therapy](/autism-therapy) to understand the whole child and build an individualised plan.\n\n## Trusted sources\nWHO ICD-11 framing of autism spectrum disorder; the American Academy of Pediatrics and HealthyChildren guidance on autism evaluation; ASHA resources on communication assessment in autism.\n\n**Next step —** If you have questions or observations about your child's development, book a developmental review with a Pinnacle clinician to understand the right next steps for your family.","canonical":"https://pinnacleblooms.org/ask/what-is-the-autism-diagnostic-interview-revised-adi-r-and-what-does-it-assess","editorial":{"reviewed_at":"2026-06-11T20:12:18.613642+00:00","reviewed_by":null,"developed_by":"SETU Consortium · Pinnacle Blooms Network"},"alternates":[{"href":"https://pinnacleblooms.org/ask/what-is-the-autism-diagnostic-interview-revised-adi-r-and-what-does-it-assess","lang":"en","indexable":true}],"dimensions":[{"key":"assessments","label":"Assessments"}],"meta_title":"ADI-R: What It Is & What It Assesses","meta_robots":"index, follow, max-image-preview:large","everyday_tip":"Before any assessment, jot down notes about your child's early development — first words, how they play with others, and any routines or favourite repeated activities.
