Can a psychologist diagnose ADHD? Yes, Psychologists complete extensive training that equips them to diagnose and treat people with ADHD using testing, interviews and therapeutic strategies. In the guide below, we explain how the ADHD assessment and diagnosis process works, the collaborative roles of psychologists, psychiatrists, and paediatricians, and how Medicare funding and referrals can support access to care.
Different Professionals: Psychologist vs Psychiatrist vs Paediatrician
Understanding who can diagnose ADHD in Australia depends on which professional you consult.
Psychologist
- Psychologists are registered health professionals specialising in human behaviour, assessment and therapy.
- Psychologists are highly trained and qualified to diagnose and treat people with ADHD using testing, interviews and therapeutic strategies.
- While psychologists perform detailed ADHD assessments and provide diagnostic opinions, they cannot prescribe ADHD medication.
Psychiatrist
- A psychiatrist is a medical doctor with specialised training in psychiatry.
- They can perform ADHD diagnosis, assess for co-occurring medical/psychiatric conditions, and prescribe medication when appropriate.
- If medication is likely to be part of treatment, GPs often refer people to a psychiatrist or organise a shared model involving both a psychologist and a psychiatrist.
Paediatrician
- Paediatricians commonly diagnose ADHD in children and adolescents.
- Paediatricians prescribe medication when appropriate and liaise with schools and other clinicians.
So, Can a Psychologist Diagnose ADHD? – The Practical Answer
Yes, a psychologist can assess for ADHD, provide a diagnostic formulation, and make recommendations. A psychologist’s report often forms the first and most comprehensive step toward a formal diagnosis.
- If the assessment is straightforward, with a clear history, no complex medical issues, and no need for medication, a psychologist’s diagnosis alone may be sufficient
- If medication is likely or complex co-morbidities are present, the psychologist may recommend a referral to a psychiatrist or paediatrician.
- Psychologists are well placed to offer ongoing support, therapy and strategies.
Why See a Psychologist for an ADHD Assessment?
There are several compelling reasons to begin with a psychologist in the ADHD diagnostic journey:
- Depth of assessment: Psychologists use structured interviews, validated rating scales and cognitive testing when needed. These tools help them differentiate ADHD from other conditions.
- Cost-effective: Seeing a psychologist first is often more cost-effective and provides a detailed report that can support medical, workplace, or NDIS pathways.
- Therapeutic support: Beyond diagnosis, psychologists provide therapy and behavioural interventions. These are important in ADHD management even when medication is used.
- Collaborative pathway: Your psychologist can forward the report to a psychiatrist or paediatrician to support medication discussions.
The Collaborative ADHD Diagnostic Process at Hively
At Hively we adopt a collaborative model to ensure appropriate diagnosis and support:
- Referral and intake – We begin with a thorough intake where we review your history, concerns and any referrals from your GP.
- Psychologist assessment – The psychologist conducts interviews, rating scales, liaises with other professionals (school, employer) if needed.
- Report and recommendations – The psychologist prepares a detailed diagnostic opinion/report and recommend next steps: therapy, and often referral via GP for medication.
- Medical consult (if required) – If medication or complex medical management is appropriate, your GP may involve a psychiatrist or paediatrician.
- Shared care and follow-up – Your psychologist and medical team often share your ongoing management to ensure coordinated care.
- Support and interventions – Regardless of medication, we recommend evidence-based behavioural strategies and support, delivered by empathetic, neuro-affirming psychologists.
This pathway ensures you’re seeing the right professional at the right time and that all pieces (assessment, diagnosis, treatment) are coordinated.
