Our ADHD Assessment Process

  • Initial Interview: The assessment begins with an in-depth initial interview. This session involves gathering detailed information about the individual's history, behaviour, and symptoms. Our experienced clinicians use this data to understand the nuances of each case.


  • Feedback Session: Following the initial interview, a feedback session is conducted. During this session, we will discuss the findings of the assessment and provide you with a comprehensive report.


  • Comprehensive Report: You will receive a detailed report indicating whether the diagnosis of ADHD has been met. This report can be used to guide further action, whether it's pursuing therapy within our clinic or seeking medical intervention from a psychiatrist.

ADHD Frequently Asked Questions

  • What does an ADHD assessment involve?

    An ADHD assessment typically includes a comprehensive evaluation by a qualified psychologist. This process often involves clinical interviews, standardised questionnaires, and behavioral observations to gather information about attention, impulsivity, and hyperactivity symptoms. The goal is to understand how these symptoms impact daily functioning and to determine if they align with ADHD diagnostic criteria.

  • Who can benefit from an ADHD assessment?

    Individuals of all ages who experience challenges with attention, organisation, impulsivity, or hyperactivity may benefit from an ADHD assessment. This includes children struggling academically, teenagers facing social difficulties, and adults encountering workplace challenges. An accurate diagnosis can lead to effective strategies and interventions tailored to the individual's needs.

  • What happens after an ADHD diagnosis?

    Following a diagnosis, the psychologist will discuss personalised treatment options. This may include behavioral therapies, counseling, educational support, and, in some cases, medication. The aim is to develop a comprehensive plan that addresses specific challenges and leverages individual strengths.

  • Are ADHD assessments covered by insurance or Medicare?

    Coverage for ADHD assessments varies depending on your insurance plan and location. Some services may be eligible for Medicare rebates under a Mental Health Care Plan. It's advisable to consult with your GP and insurance company to understand the specifics of your coverage.​
