The core difference is training and role: a psychiatrist is a medical doctor who can make the formal ADHD diagnosis and look after treatment, including medication where clinically appropriate, while a psychologist is an expert in assessment and therapy who leads the in-depth ADHD assessment but does not prescribe. For ADHD in Australia, you usually benefit from both working together.
If you've been trying to work out which one to see, this comparison lays it out plainly — what each profession is trained in, what they do in ADHD care, who diagnoses, who can prescribe, and who to see when. The short version: it's rarely a choice between them, and a good telehealth pathway joins them up for you.
Psychiatrist vs psychologist: the quick comparison
Here's the side-by-side on the points people care about most:
- Training — Psychiatrist: a medical doctor who completed medical school then specialist psychiatry training. Psychologist: a university-trained expert in psychological assessment and therapy, registered with AHPRA, but not a medical doctor.
- Role in ADHD care — Psychiatrist: confirms the medical diagnosis and manages treatment. Psychologist: leads the comprehensive assessment and provides practical strategies and therapy.
- Who diagnoses — Psychiatrist: makes the formal medical diagnosis used for prescribing. Psychologist: assesses in depth and identifies an ADHD presentation, feeding into that diagnosis.
- Who can prescribe — Psychiatrist: yes, where clinically appropriate, with prescribing regulated in Australia. Psychologist: no, psychologists cannot prescribe.
- Main focus — Psychiatrist: the medical picture, diagnosis and treatment. Psychologist: detailed assessment, behavioural strategies and support.
- Referral and Medicare — Psychiatrist: a GP referral is usually needed for a Medicare rebate. Psychologist: a referral may be relevant for some rebates depending on your circumstances.
What does a psychologist do for ADHD?
A registered psychologist usually leads the most detailed part of the process — the comprehensive assessment. They are trained to gather a careful, whole-of-life history and to use standardised, validated tools, building the evidence base that a medical diagnosis relies on.
Typically a psychologist will:
- Take a detailed history of your difficulties across childhood, school or work, relationships and daily life.
- Administer standardised questionnaires, sometimes including input from someone who knows you well.
- Screen for overlapping factors such as sleep, anxiety or mood that can mimic ADHD.
- Offer practical, evidence-based behavioural strategies and therapy to help with day-to-day challenges.
- Produce a clear written summary that informs the medical diagnosis and can be shared with your GP and psychiatrist.
What does a psychiatrist do for ADHD?
A psychiatrist is a medical doctor who specialises in mental health, which is why the medical side of ADHD sits with them. They bring a medical lens to the assessment findings, consider your wider health, confirm the diagnosis where the recognised criteria are met, and take responsibility for treatment.
A psychiatrist will generally:
- Review the assessment findings, including a psychologist's detailed work, through a medical lens.
- Confirm a formal diagnosis where the recognised criteria are met, and explain in plain English what it means for you.
- Develop a treatment plan, which may include medication where it is clinically appropriate — a decision made only after a proper assessment, never promised in advance.
- Oversee ongoing reviews and, over time, coordinate prescribing as shared care with your GP.
Who should I see first for ADHD?
For most people the practical starting point is your GP, who can talk through your concerns, provide a referral, and remain part of your shared care. From there, an in-depth assessment is usually psychologist-led, with the psychiatrist confirming the diagnosis and managing treatment where appropriate.
A simple way to think about who does what:
- See your GP first for a referral and to keep your broader health in the picture.
- See a psychologist for the in-depth assessment and for practical strategies and therapy.
- See a psychiatrist for the formal medical diagnosis and for treatment, including medication where clinically appropriate.
- Lean on shared care with your GP for ongoing management once a plan is in place.
How do they work together in a telehealth pathway?
The most effective ADHD care isn't a single appointment with one professional — it's a coordinated team. The Australian Evidence-Based Clinical Practice Guideline for ADHD, developed by AADPA, supports this kind of multidisciplinary, joined-up approach. At Seen ADHD, a registered psychologist leads the in-depth assessment, a psychiatrist provides input and confirms diagnosis and treatment where clinically appropriate, and your GP is part of shared care — all by secure video, from home, anywhere in Australia.
As a guide to what's involved: an Initial Telehealth Assessment starts from $149, the core Seen ADHD Pathway is $995 for a two-hour psychologist-led assessment with psychiatrist input where appropriate, and ongoing Treatment & Review care starts from $1,495. Rebates are situational and never guaranteed, so confirm what applies to you with your GP. And remember, not everyone who is assessed will meet the criteria for ADHD — an honest "no" is a valid and useful outcome.
