CAAAS Research Study

Research Study

About this study
We're recruiting parents or carers of children aged 4-17 years in a study to psychometrically validate a new tool to measure symptoms that commonly co-occur with autism spectrum disorder (ASD).

This study aims to determine the psychometric properties of a new user-friendly scale to measure the frequency and impact of symptoms that commonly co-occur with autism on daily functioning, in children aged 4-17 years.

Who is this study for - eligibility criteria
- Parents or carers or children aged 4-17 years with a formal diagnosis of autism spectrum disorder (ASD)
- Fluent in English (written and verbal)
- US Resident

What does the study involve?

- If the ADI-R or ADOS has not previously been administered, or results cannot be provided, the ADI-R will be conducted by one of our qualified psychometrists. This is a 45 to 90 minute interview with the parent or carer by phone or Zoom.
- Completing the new autism measure - the CAAAS, Child (10-15 minutes), and providing feedback (3-5 minutes)
- Completing the following additional questionnaires about your child: Aberrant Behaviour Checklist (ABC-2) (10 minutes), Social Responsiveness Scale (SRS-2) (15 minutes), Autism Treatment Evaluation Checklist (ATEC) (10 minutes), the Autism treatment network GI signs & symptoms Inventory-17 (8 minutes), and three additional questions on medical symptoms (2 minutes).
- Completing the CAAAS, Child a second time (for test-re-rest reliability) approximately two weeks after the original completion of the CAAAS, Child

Participants will be compensated with a $50USD gift card for their time.

Importance of this study
Although many questionnaires have been developed for autism, most were originally developed as diagnostic tools. Further, the majority were developed to assess only core autism symptomatology, and not symptoms that also commonly co-occur with autism. This study will help psychometrically validate a new tool to measure symptoms that commonly co-occur with autism, and evaluate the effectiveness of interventions.
