Yes, a clinician-led ADI-R can be administered without a parent or caregiver, especially in adult cases. The ADI-R (Autism Diagnostic Interview-Revised) is traditionally designed to be conducted with someone who knew the individual during early development, but in situations where that is not possible, clinicians can adapt the approach using their expertise.

How Clinicians Administer the ADI-R Independently

Here’s how a clinician-led ADI-R works when caregivers are unavailable:

Professional Interview

The clinician uses structured questions from the ADI-R to gather detailed developmental information. In the absence of a parent or carer, they may conduct a professional interview with the individual or draw on past records and alternative information to gather necessary insights.

No Caregiver

While the ADI-R was designed with caregiver input in mind, diagnosis can still proceed with no caregiver present. This is particularly relevant for adults who may not have access to someone who can recall their early development. Clinicians may instead use corroborating information from other sources to support their conclusions.

Clinical Flexibility

Skilled professionals adapt the tool depending on context, ensuring clinical flexibility without compromising the quality of the assessment. A well-conducted, clinician-led ADI-R can still contribute meaningfully to a diagnosis when combined with other observations and tools.

The clinician-led ADI-R is a flexible option for those navigating autism assessment without caregiver input. For supportive and professional diagnostic services, visit providers like Autism Detect for consultations.
