Adult Autism Assessment Cardiff

Our Adult Autism Assessments in Cardiff are grounded in a neuro-affirming, strengths-based approach. We recognise autism as a natural and valid variation in how people experience and interact with the world, rather than something to be treated.

We focus on understanding your lived experience in a respectful and supportive way, including both strengths and challenges, and how autism may present across your daily life.

We provide assessments for adults who may be:

  • Exploring whether they may be autistic for the first time
  • Seeking a formal autism diagnosis for self-understanding
  • Living in Cardiff or South Wales and wanting clarity about lifelong traits
  • Experiencing ongoing challenges related to social interaction, sensory processing, or executive functioning
  • Already diagnosed with ADHD, anxiety, depression, or other neurodivergent conditions and seeking a clearer profile

What Our Adult Autism Assessment in Cardiff Includes

Our comprehensive Adult Autism Assessment in Cardiff follows recognised best practice and is informed by NICE guidance for autism assessment in adults, ensuring a thorough, evidence-based, and person-centred process.

The assessment includes:

  • Detailed developmental history from childhood to present
  • Full clinical interview with an experienced clinician
  • Structured autism assessment tools (such as ADOS-2 where appropriate)
  • Exploration of social communication and interaction differences
  • Assessment of sensory processing differences
  • Understanding of routines, behaviours, and executive functioning
  • Exploration of masking, camouflaging, and coping strategies
  • Consideration of co-occurring conditions (e.g. ADHD, anxiety, depression, trauma)
  • Differential diagnosis to ensure clinical accuracy
  • Functional impact across daily life, relationships, education, and employment

Autism Assessment Pathway for Adults in Cardiff

1. Initial Enquiry & Free Consultation

Your journey begins with an enquiry. We offer a free 15-minute consultation for individuals in Cardiff and across South Wales to discuss your concerns, answer questions, and help you decide whether an Adult Autism Assessment is the right step.

2. Pre-Assessment Questionnaire

You will complete a detailed pre-assessment questionnaire to help us understand your current experiences, developmental history, strengths, and challenges.

3. Informant Information (Where Possible)

Where appropriate, we may ask a partner, family member, or someone who knows you well to provide additional developmental insight. If this is not possible, your clinician will guide you through alternative options.

Your assessment is conducted by experienced clinicians either face-to-face in Cardiff or via secure online consultation for individuals across Wales and the UK. The assessment includes a detailed developmental history, structured clinical interview, and standardised autism assessment tools, alongside consideration of co-occurring conditions.

Following your assessment, all information is carefully reviewed before a diagnostic outcome is reached. You will receive clear feedback and an explanation of the findings, whether or not a diagnosis of autism is made.

  • Assessment findings and diagnostic outcome
