Autism Assessment for Adults

AUTISM ASSESSMENT FOR ADULTS

At Neuroaffinity, we offer high-quality autism assessments for adults across the UK, online and in person.

If you’ve always felt “different,” struggled with social interactions, sensory overload, or maintaining routines and relationships, you may be wondering if autism could be the reason.

Our team of HCPC-registered clinicians provides compassionate, evidence-based adult assessments for autism designed to bring clarity and support, no matter where you are in life.

Why Choose a Private Adult Autism Assessment?

Many people reach adulthood without ever receiving an autism diagnosis. Some may have spent years masking their traits, being misdiagnosed with anxiety or depression, or simply feeling misunderstood.

An assessment for autism in adults can offer important validation and a clearer understanding of yourself, your needs, and your strengths.

Choosing a private autism assessment for adults with Neuroaffinity means:

– Bypassing long NHS waiting lists
– Working with expert psychologists experienced in late-diagnosed autism
– Receiving a clear, well-evidenced diagnosis (if applicable)
– Gaining tools and recommendations to navigate life more confidently

Whether you’re seeking a diagnosis for personal insight, workplace accommodations, or mental health support, your reason is valid, and we’re here to help.

What to Expect from Our Adult Autism Assessment Process

Our autism assessments for adults in the UK follow a clear, clinically rigorous process, while staying supportive and neurodiversity-affirming:

The Autism Assessment Process Includes Several Steps

Initial Screening

You’ll complete rating scales and questionnaires to evaluate autism symptoms and their impact. An assessment fee is charged only if you pass this initial screening.

Additional Background Information

Additional details may be gathered from family members or partners to gain a complete understanding of your symptoms.

Clinical Interview

A specialist autism clinician will conduct a clinical assessment through a face-to-face consultation or via a video conference, which will last between 60 and 90 minutes. For adults, it is beneficial if a family member who has known them since childhood can be present during this assessment.

Observational assessment

A second face-to-face or video conference will be conducted, during which our specialists will observe how you interact in various settings. They will assess important aspects of communication, social skills, and repetitive behaviours. This evaluation may involve assessment tools like the ADOS-2 and can last up to 90 minutes.

Diagnostic Decision and Feedback

Based on the gathered information, a diagnostic decision will be made according to the criteria from the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). This will be done at a separate feedback appointment.
