With Dr Sonney Gullu-McPhee, Psy.D, MA, MSc, BSc (Hons)
Chartered Clinical Psychologist | HCPC & BPS Registered | ISST Certified Advanced Schema Therapist
Private ADHD assessments for adults aged 17+ available in Petersfield, Hampshire and online across the UK.
Many adults who come to me have spent years - sometimes decades - trying to understand why certain things feel harder than they seem to for others.
They are often capable, high-functioning, and managing on the surface, yet exhausted by the effort it takes to keep up.
If you’ve been wondering whether ADHD might explain some of these long-standing patterns, this assessment is designed to give you a clear and thoughtful understanding of your experiences.
IS THIS RIGHT FOR YOU?
You may benefit from an ADHD assessment if you:
- Have struggled with focus or organisation for years
- Feel overwhelmed by everyday responsibilities
- Suspect ADHD may explain long-standing patterns
- Want a clear, professional understanding of what's going on
HOW I CAN HELP
A Clear, Structured Understanding
If ADHD may be part of your experience, this assessment provides a clear, structured understanding of what’s going on and what to do next.
This is a careful, comprehensive assessment designed to understand your experiences in depth – across different stages of life and areas of functioning, not a quick checklist or test-based diagnosis.
WHAT YOU WILL RECEIVE
Your Assessment Includes
- A thorough, evidence-based assessment informed by NICE guideline NG87 for ADHD
- A comprehensive written report you can use with your GP, employer, or insurer
- Personalised recommendations tailored to your specific profile
- Honest, clear feedback, whether or not ADHD is diagnosed
- Guidance on next steps, including medication referral where relevant
The aim is for you to leave with a clearer understanding of how your experiences have developed over time, how they affect your day-to-day functioning, and a sense of direction about what to do next.
ASSESSMENT PROCESS
A Thorough, Considered Process
This is a careful, comprehensive process, not a high-volume service. I take a small number of new clients each month specifically so that each assessment gets the depth and attention it deserves.
Step 1
Free 15-minute consultation
A brief, no-obligation call to talk through your concerns, answer your questions, and explore whether an assessment feels like the right next step for you.
Step 2
Screening consultation (60 minutes)
An in-depth session exploring your current difficulties, background history, and whether proceeding to a full assessment is clinically appropriate. This session alone often brings significant clarity.
Step 3
Full ADHD assessment (2 hours)
A detailed clinical assessment exploring your experiences across childhood and adulthood, including patterns of attention, organisation, and emotional regulation over time. This includes a structured clinical interview, developmental history, and consideration of how your difficulties present across different areas of life, including work, relationships, and day-to-day responsibilities.
The assessment also considers how these patterns occur across different settings, in line with recognised diagnostic standards. Where appropriate, standardised measures may be used to support clinical understanding, alongside information from multiple sources where available.
Step 4
Feedback session and written report (30-60 minutes)
I will provide a clear explanation of the outcome, along with a comprehensive written report and personalised recommendations, including guidance on medication pathways where appropriate.
WHY PEOPLE CHOOSE THIS ASSESSMENT
What Sets This Assessment Apart
Conducted by an experienced Chartered Clinical Psychologist
This is not a high-volume or questionnaire-based service. I hold a Doctorate in Clinical Psychology and have extensive postdoctoral training in comprehensive psychological assessment. I personally carry out and interpret every assessment.
Rigorous, multi-method assessment
Rather than relying on a single questionnaire or self-report tool, I draw on clinical interview, developmental history, and where appropriate, standardised psychometric measures, considered together with clinical judgement.
Careful consideration of the full picture
ADHD does not exist in isolation. Where other factors such as anxiety, depression, trauma, or autism may overlap or better explain your experiences, these will be carefully considered and reflected clearly in the report.
Available in Hampshire and online across the UK
Remote assessments are conducted via secure video call and carry the same clinical depth as in-person sessions. Whether you are in Petersfield or elsewhere in the UK, you will receive the same thorough and personalised service.
DO THESE DIFFICULTIES FEEL FAMILIAR?
Common Patterns in Adult ADHD
ADHD doesn’t always look the way people expect, especially in adults. You might recognise some of these patterns in yourself:
Attention and focus
- Struggling to stay focused, especially on tasks that don’t interest you
- Your mind drifting or switching quickly between thoughts
- Finding it hard to finish tasks, even when you’ve started with good intentions
Organisation and daily life
- Feeling disorganised or overwhelmed by everyday responsibilities
- Losing track of important things like keys, appointments, or deadlines
- Difficulty planning or breaking tasks into manageable steps
Time and follow-through
- Chronic procrastination or leaving things until the last minute
- Underestimating how long things will take
- Feeling like you are always trying to catch up
Motivation and task initiation
- Struggling to get started on tasks, even when they feel important
- Needing pressure or urgency to begin
- Feeling stuck or unable to follow through despite good intentions
Emotional experience
- Feeling easily overwhelmed or mentally overloaded
- Emotional ups and downs or sensitivity to stress
- Frustration with yourself for not doing things the way you “should”
Restlessness and mental activity
- A busy or constantly active mind
- Difficulty switching off or relaxing
- Feeling internally restless, even if you don’t appear hyperactive
Many people come to an ADHD assessment after years of trying to understand themselves. This process is designed to provide clarity, not judgement.
CLINICAL APPROACH
How the Assessment Works
My approach to ADHD assessment is structured, comprehensive, and grounded in recognised UK clinical standards.
Rather than relying on a single test or checklist, I take a formulation-led approach, drawing together your history, current experiences, and the context in which your difficulties occur.
The aim is to develop a clear and balanced understanding of your individual profile, considering both strengths and challenges, and whether ADHD or other factors may best explain your experiences.
LOOKING FOR A BROADER UNDERSTANDING?
Beyond a Single Diagnosis
For some people, the goal is not to identify a specific diagnosis, but to gain a deeper and more complete understanding of themselves.
If you are looking for a structured and in-depth understanding of your personality, emotional patterns, and how your experiences fit together, I also offer a comprehensive psychological profiling assessment.
Comprehensive Psychological Profile
A comprehensive psychological assessment designed to develop a clear and integrated understanding of your psychological functioning. This is a formulation-led process focused on understanding the whole person, rather than assessing for a specific condition or diagnosis.
COMMON QUESTIONS
Frequently Asked Questions
How is this different from an NHS assessment?
NHS waiting lists for adult ADHD assessment currently run to several years in many areas. This service offers the same clinical rigour with no waiting list, a more thorough process, and a detailed written report suitable for use with employers, academic institutions, or your GP.
Will the report be shared with anyone?
No. Your report is confidential and shared only with you. You decide who to share it with. A shorter summary letter can also be provided if needed.
What if I don't meet the criteria for ADHD?
This is more common than people expect, and it does not mean the process has been wasted. You will leave with a clear understanding of what is affecting you and what to do next.
How long does the report take?
The written report is typically provided within two weeks of your assessment session.
Can I explore medication if ADHD is diagnosed?
Yes. If ADHD is diagnosed and medication feels appropriate, a referral to a medical professional will be provided.
Are online assessments as thorough as in-person ones?
Yes. Remote assessments follow the same clinical process and depth, and many clients find them more comfortable and convenient.
