Not sure where to start? A screening consultation can help
If you’re unsure whether to have a full neurodevelopmental assessment, or which assessment might suit you best, a screening consultation is a good first step.
The consultation lasts one hour and can take place in person or remotely. A Clinical Psychologist will carry out a structured clinical interview to explore your mental health and neurodevelopmental history, using validated screening tools suited to your needs.
At the end of the session, you’ll receive personalised recommendations – which might include a neurodevelopmental assessment, psychological therapy, or a psychiatry consultation. If you’d like to go ahead, we can arrange any internal referrals, and you’ll receive a written summary that can be shared with your GP.
Stage 1: your initial consultation
This appointment covers an overview of the assessment process and potential outcomes, along with a comprehensive clinical interview discussing your background, daily functioning, relationship history, education and employment, medical and mental health history, and symptoms or experiences relevant to ADHD and autism.
Length: up to 90 minutes
With: a Consultant Psychiatrist
Who should attend: alone, or with someone who knows you well
How: online or in person
Stage 2: DIVA-5 and developmental history
The DIVA-5 (Diagnostic Interview for ADHD in Adults, Fifth Edition) is a structured clinical interview assessing symptoms of ADHD in childhood and adulthood, in line with DSM-5 criteria – exploring inattention, hyperactivity, and impulsivity through real-life examples of their presence, severity, and impact.
This stage also includes a comprehensive developmental history, helping establish whether symptoms were present in childhood, through early behaviour, school experiences, family context, and social development.
Length: up to two hours
With: a Consultant Psychiatrist or Clinical Psychologist
Who should attend: please bring someone who’s known you well since you were a baby or young child, if possible
How: online or in person
Stage 3: the ADOS-2
The ADOS-2 (Autism Diagnostic Observation Schedule, Second Edition) is an evidence-based assessment tool that helps clinicians understand whether someone may be autistic. It’s a structured but relaxed session, guiding you through conversational topics and activities exploring communication style, social interaction, imagination, and patterns of behaviour. There are no “right” or “wrong” answers – it’s an opportunity to be yourself, while the clinician observes how you naturally communicate and engage.
Length: up to 90 minutes
With: a Clinical Psychologist or Speech and Language Therapist
Who should attend: you attend this appointment alone
How: in person
Stage 4: team discussion
Our multidisciplinary team comes together to carefully review everything gathered – interviews, observations, questionnaires, and developmental history – ensuring any diagnosis of ADHD and/or autism is based on clear, evidence-based DSM-5 criteria, and that conclusions and recommendations are thoughtful and tailored to you.
Stage 5: your feedback appointment
At your feedback appointment, we take time to talk through your results clearly and supportively – explaining what we found, how it relates to your experiences, and whether the findings are consistent with autism and/or ADHD. There’s plenty of space for questions and reflection.
We’ll talk through personalised recommendations, which may include strategies, support options, psychological approaches, and/or medication, and highlight your individual strengths and differences.
Length: up to one hour
With: the same Consultant Psychiatrist you met at your first appointment
Who should attend: alone, or with someone you’d like to bring
How: online or in person
Your report and further appointments
A comprehensive report is sent to you and your GP around 4 weeks after your feedback appointment.
If further appointments are needed out with the full assessment, these may incur additional charges.
FAQs
It’s a comprehensive evaluation designed to assess for both Autism Spectrum Disorder and Attention‑Deficit/Hyperactivity Disorder in one coordinated process, rather than doing two separate assessments. This helps clinicians understand how traits of both conditions may present and interact for an individual.
Assessments are led by experienced clinicians — including Consultant Psychiatrists, Clinical Psychologists, and our Speech and Language Therapist — who specialise in neurodevelopmental conditions such as autism and ADHD.
Once all the assessments, questionnaires and developmental history have been reviewed, a feedback session is scheduled. In this session the clinician explains whether ADHD, autism, both or neither are present, and discusses next steps including support options.
