Our adult Autism (ASD) assessments are designed to help you gain a clear understanding of whether autism may be influencing the way you experience, interpret, and interact with the world around you. Each assessment is carried out by experienced clinicians and follows national best practice and NICE (National Institute for Health and Care Excellence) guidelines to ensure accuracy, consistency, and respect for each individual’s experience.

How the Assessment Works

1. Initial Screening & Background Information

   The process begins with a structured screening stage. You’ll be asked to complete background questionnaires and provide developmental history where possible (for example, early childhood information from family members, if available). This helps our team understand your communication style, sensory profile, relationships, education and work history, and everyday challenges or strengths.

2. Comprehensive Diagnostic Assessment

   You’ll then meet with one of our specialist clinicians for an in-depth online assessment. This is usually conducted by a specialist ASD clinician typically a Registered Mental Health Nurse, consultant psychiatrist and clinical psychologist. 

   The assessment uses recognised diagnostic tools such as:

   • ADOS-2 (Autism Diagnostic Observation Schedule, 2nd Edition) modules adapted for adults

   • ADI-R (Autism Diagnostic Interview – Revised) where developmental input is available

   • Standardised self-report and observer questionnaires (e.g. AQ, RAADS-R, EQ)

   • Clinical interview exploring social communication, repetitive behaviours, sensory sensitivities, and adaptive functioning

   The goal is to build a detailed understanding of how your experiences align (or do not align) with current diagnostic criteria for Autism Spectrum Disorder, while acknowledging your individuality and strengths.

3. Diagnostic Formulation & Clinical Review

   Following your appointment, the clinician reviews all gathered information — including your interview, questionnaires, and collateral reports if available — to reach a diagnostic conclusion in line with DSM-5 and/or ICD-11 criteria. Where needed, the case may be discussed at a multi-disciplinary team (MDT) meeting to ensure a balanced, evidence-based outcome.

4. Written Diagnostic Report & Feedback Session

   You’ll receive a detailed written report summarising:

   • The diagnostic outcome (confirmed, not confirmed, or inconclusive)

   • A clear explanation of how the decision was reached

   • Your unique strengths and support needs

   • Recommendations for workplace or educational adjustments, and signposts for further support

   A short follow-up feedback call can be arranged to discuss your report and next steps.

Important Information About Follow-Up

The initial assessment package covers the full diagnostic process described above — from screening to written report.

Post-diagnostic support and follow-up sessions are not included in this package.

However, we offer separate post-diagnostic packages that can include:

• One-to-one guidance sessions

• Workplace or university liaison reports

• Referrals for counselling, coaching, or occupational therapy

• Medication or mental health reviews (if indicated)

These options can be arranged once your diagnostic report is complete, so you remain fully supported at your own pace.
