Yes, the ADI-R for adult diagnosis is considered safe and effective when used correctly. Originally designed for children, the Autism Diagnostic Interview-Revised (ADI-R) can still offer valuable insights into adult diagnoses, especially when historical information from caregivers is available and the assessment is adapted to suit mature individuals.

How Safe and Valid Is ADI-R for Adults?

Here’s what to consider when using the ADI-R for adult diagnosis:

Interview Validity

The tool relies heavily on early developmental history, usually collected from a parent or caregiver. In adults, this can raise concerns about interview validity, particularly if accurate recall is difficult or caregivers are unavailable. Despite this, when thorough records or reliable informants are present, the ADI-R remains a solid foundation for identifying longstanding traits of autism.

Diagnostic Safety

The structured nature of the ADI-R offers diagnostic safety by reducing subjective bias. However, it’s important to pair the results with current behavioural assessments, as adults may have developed coping strategies that mask symptoms. Using the ADI-R as part of a broader diagnostic process helps avoid misinterpretation and ensures a well-rounded evaluation.

Mature Assessment

Adults often require a more nuanced and respectful approach. The ADI-R, when used with sensitivity and in tandem with other tools, contributes to a mature assessment that recognises both past and present experiences.

In summary, the ADI-R for adult diagnosis is safe and useful, especially when handled by experienced clinicians. For personalised support, visit providers like Autism Detect for tailored adult consultations.
