What Does This Screening Cover?

How This Screening Differs from Traditional Tests

Traditional tools — the AQ-10, AQ-50, and RAADS-R — use fixed statements rated on a scale. They were developed primarily with male participants and can miss presentation patterns common in women, non-binary people, and late-diagnosed adults. The AQ-10 in particular was designed as a quick clinical triage tool, not a nuanced self-assessment, and its binary framing struggles to capture the complexity of autistic experience across different social contexts.

This screening specifically accounts for masking — the camouflaging of autistic traits — which tools like the CAT-Q measure separately. Many people score “not autistic” on the AQ-10 precisely because they mask so well. The questions don't distinguish between “I don't struggle with this” and “I've learned to hide that I struggle with this.” For women and adults who received no early support, decades of compensatory strategies can make traditional questionnaires almost meaningless as a screening instrument.

AskSheldon's screening uses adaptive questioning that explores multiple domains and captures nuance through AI analysis, rather than a fixed questionnaire with a binary cutoff score. The questions probe not just whether you do something, but whether it is effortful, draining, or requires conscious scripting — distinctions that matter enormously for late-diagnosed adults.

How Is This Different from a Clinical Diagnosis?

A screening identifies traits and patterns consistent with autism. It tells you whether your experiences align with those commonly reported by autistic adults. A formal diagnosis, by contrast, requires a qualified clinician to conduct structured interviews, review developmental history, and apply standardised diagnostic criteria such as DSM-5 or ICD-11.

Screening is a useful first step. It helps you gather your thoughts, articulate your experiences, and arrive at a clinical appointment with structured evidence rather than a vague sense that something feels different.

What Happens After the Screening?

After completing the screening, you receive a detailed summary of your trait profile across each domain. This includes where your responses sit relative to clinical thresholds and what those patterns might mean in everyday life.

If your results suggest further exploration is worthwhile, you have several options. You can ask your GP for an NHS referral, use the Right to Choose pathway to access a provider of your choice, or pursue a private assessment. Our guide on adult autism diagnosis in the UK walks through each route in detail.

You can also continue with AskSheldon's full diagnostic-style assessment, which collects more detailed evidence, invites informants to contribute their observations, and produces a clinical-grade report you can share with your clinician.

If your results suggest autistic traits, you may want to learn about recognising autistic burnout — a common experience for undiagnosed adults. Our sensory overload toolkit also has immediate support tools you can use while processing your results.

What You Can Do Right Now

Whether or not you decide to take a screening, here are practical steps you can take today:

• Talk to your GP. If you suspect you may be autistic, book an appointment and ask for a referral to an autism assessment service. Bring specific examples of how traits affect your daily life.
• Start journaling your experiences. Write down situations where you notice sensory sensitivity, social exhaustion, or need for routine. This personal evidence is useful for both self-understanding and clinical assessment.
• Connect with autistic communities. The National Autistic Society and online peer groups offer spaces to share experiences and learn from people who understand.

AskSheldon goes beyond a simple questionnaire. When you complete a full assessment, your responses are analysed by a multi-disciplinary team (MDT) of five independent AI agents. Each agent examines your evidence from a different clinical perspective before cross-reviewing each other's findings and reaching a consensus formulation. The platform also supports multi-informant evidence gathering. Learn more on our How It Works page.
