Yes, the use of combined diagnostic tools, such as pairing the ADOS‑2 and ADI‑R within streamlined, multi-method assessments, is increasingly under evaluation in clinical trials and research. These approaches aim to integrate structured observation with caregiver interviews to boost efficiency and accuracy in autism diagnosis.

What Combined Tools Are Being Tested?

Several studies and pilot trials are exploring integrated assessment methods:

Clustering of ADOS and ADI-R Data

A data-driven study involving 2,310 participants used machine learning to analyse ADOS and ADI-R responses together. This revealed distinct symptom subtypes and suggested that subsets of items from both tools can effectively distinguish autism presentations with high accuracy (over 90%) in certain groups.

Questionnaire and Video-Based Screening

Emerging models combine parent-report questionnaires with home video analysis. A machine-learning study found this hybrid method offered faster, cost-effective screening while preserving reliability comparable to traditional tools like ADI‑R.

Multimodal Neuroimaging Models

Research combining EEG, fMRI and machine learning is trialling ways to supplement behavioural tools with biological data. These multi-method assessments aim to improve early detection and understanding of autism’s neural markers.

Why Combined Methods Are Promising

These integrated routes matter because:

They mirror real-world diagnostic practice, where structured interviews and observations are used together for better clarity and consistency.

Brief cross-tool screening strategies could shorten waitlists and reduce clinician burden.

Early findings indicate potential for high accuracy while supporting integrated screening in both clinical and community contexts.

Overall, combined diagnostic tools are an exciting frontier, backed by trials seeking to deliver faster, more accessible, and equally reliable autism assessment pathways. For trusted evaluation integrating both traditional tools and emerging methods, visit providers like Autism Detect.
