Experimental: Autistic

This will be participants who are waiting for an autism assessment in the Oxfordshire CAMHS Neurodevelopmental Conditions (NDC) pathway. The participant are will complete the OVAAT and an ADOS-2 assessment.~The participant will have a neurodevelopmental assessment using the ADOS-2 is an existing tool that we use to assess autism and a developmental history - this is the current standard assessment process. They will receive feedback from this appointment. The second appointment will be using the OVAAT. This assessment will be video and audio recorded (through Microsoft Teams) so that we can check whether another clinical researcher comes to the same conclusion as the person providing the OVAAT. We will only keep the recording until the 2nd researcher has watched and listened to the recording.

Experimental: Neurotypical

These participants will be neurotypical young people recruited from the general population of Oxfordshire. They will only receive an OVAAT appointment.~The participants will first complete screening measures to assess their eligibility for the study. If they are still eligible, an OVAAT appointment will be arranged. This will be the same process as group 1. This assessment will be video and audio recorded (through Microsoft Teams) so that we can check whether another clinical researcher comes to the same conclusion as the person providing the OVAAT. We will only keep the recording until the 2nd researcher has watched and listened to the recording.
