Evaluating the Oxford Virtual Autism Assessment Tool OVAAT for Diagnosing Autism in Teens Aged 13 to 18

What this Trial Is About

Researchers are evaluating the Oxford Virtual Autism Assessment Tool OVAAT, a new online diagnostic tool for Autism Spectrum Disorder ASD. The study aims to see if the OVAAT can identify autistic traits, distinguish between autistic and non-autistic young people, and compare its performance to the existing ADOS-2 observational tool. This research addresses the need for a standardised virtual assessment that captures both observable and self-reported ASD features, especially for young people who prefer online assessments. Participants are divided into two groups Group 1 includes 13 to 18 year olds awaiting an autism assessment within the Oxfordshire CAMHS Neurodevelopmental Conditions pathway, who will complete both the OVAAT and the ADOS-2 assessments. Group 2 consists of neurotypical young people aged 13 to 18 with no neurodevelopmental or mental health conditions, who will complete screening questionnaires and the OVAAT only. The OVAAT assessments are video and audio recorded via Microsoft Teams to allow a second clinical researcher to verify the findings. Throughout the study, participants will complete questionnaires that assess features of autism, ADHD, and common mental health conditions. The recordings from the OVAAT will be kept only until reviewed by a second researcher. Participants may receive a 10 Amazon voucher after completing the required assessments. The primary outcome is the evaluation of the OVAAT up to three weeks after recruitment. Secondary measures include established scales like the Revised Childrens Anxiety and Depression Scale and the Autism Diagnostic Observation Schedule ADOS-2. Safety monitoring includes confidentiality protections and pathways for further support if mental health concerns arise.
