ADHD Assessment, Diagnosis & Treatment with Our Psychologists
Attention deficit hyperactivity disorder (ADHD) is the most common neurodevelopmental disorder in Australia. ADHD affects more than 1 million Australians – 6-8% of children and 3-5% of adults.
Since the Australian clinical guidelines for ADHD were released in October 2022, an increasing number of people with ADHD have been able to obtain an accurate diagnosis and access the support they need for a better quality of life.
New Vision Psychology has a team of clinical and registered psychologists who support people with ADHD. We use evidence-based ADHD assessments for screening and diagnosis, and provide tailored support through ADHD psychology.
We provide ADHD screening sessions for both adults and children at our Sydney clinics. In this 1-hour session, we will administer an ADHD screener and advise you if a formal assessment is necessary. No medical referral is required to undergo ADHD screening or assessments.

Important Note: Psychologists do not prescribe medication for ADHD. Psychologists diagnose and treat ADHD.
To receive medication, you will need to see a psychiatrist and/or GP.
What happens during an ADHD assessment?
If our psychologists determine that a formal ADHD assessment is appropriate, we will administer a range of tests based on the initial screening questionnaire and the clinical interview.
These tests may include a cognitive assessment (Wechsler Intelligence Scale for Children (WISC-V) or the Wechsler Adult Intelligence Scale (WAIS-IV) ) to inform the psychologist about cognitive strengths and weaknesses and tailor specific treatment methods.
We develop a psychological report containing a diagnosis for ADHD (if criteria are met), cognitive strengths and weaknesses related to ADHD symptoms, and a treatment plan for ongoing support. All of this will be communicated to you during a feedback session.
ADHD Counselling for Adults & Children
ADHD is a lifelong condition that develops during childhood and continues into adulthood. ADHD symptoms are experienced differently in adults than in children or teenagers, but can still have a significant impact on a person’s studies, work, personal life and relationships.
Children and adults with ADHD can receive support for managing symptoms through ADHD counselling and therapy. ADHD treatment provides strategies to address symptoms such as excessive fidgeting or restlessness, difficulty paying attention and staying organised, and trouble with self-control or impulsivity.
The latest Australian ADHD guidelines detail the importance of access to multimodal treatments, including medication and non-medication (psychological) treatments. Non-medication treatments include lifestyle changes, parent/family training, cognitive-behavioural interventions and ADHD coaching. The guidelines recommend that people with ADHD should be taught how to minimise symptoms and maximise their personal strengths. Receiving early diagnosis and treatment can have a huge impact on a person’s life.
At New Vision Psychology, we take a personalised approach to ADHD therapy by considering each individual’s requirements. A tailored treatment plan is created for each client, considering factors such as the severity of their symptoms, and whether they have other coexisting conditions like ASD, anxiety, ODD or mood disorders.
