Understanding the Process of Diagnosing ADHD in Adults
What’s Involved in an Adult ADHD Assessment?
Attention-Deficit/Hyperactivity Disorder (ADHD) is often associated with childhood, but many individuals reach adulthood without a formal diagnosis. For those who have long struggled with focus, impulsivity, or executive functioning challenges, seeking an ADHD assessment can be a valuable step toward understanding themselves better. However, navigating the diagnostic process can be confusing, especially when it comes to knowing what is required and what to expect.
A comprehensive ADHD assessment does not necessarily require a full cognitive (IQ) assessment. While cognitive testing can provide additional insights, ADHD is primarily diagnosed through clinical history, standardised questionnaires, and structured interviews. Research highlights that ADHD in adulthood is often underdiagnosed due to a lack of awareness and training among healthcare professionals (Kooij, 2012). My approach prioritises accessibility and cost-effectiveness, ensuring that neurodiverse individuals can access appropriate assessments without unnecessary expenses.

The process is spread across 2-3 sessions and includes:
Initial ADHD Screener (30 minutes, $150 - Online): A brief screening appointment to determine whether a full ADHD assessment is appropriate for you.
Clinical Interview: A thorough discussion of developmental history, current challenges, and relevant medical or psychological history.
Standardised ADHD Checklists: Evidence-based tools completed by the individual (and sometimes a significant other) to assess ADHD-related symptoms.
Diagnostic Interview for ADHD in Adults (DIVA): A structured interview specifically designed for diagnosing ADHD.
CAARS (Conners’ Adult ADHD Rating Scales): A standardized assessment tool measuring ADHD symptoms in adulthood.
Brief Report: A summary of findings and recommendations, which can be shared with relevant professionals if needed.
Key Considerations in Adult ADHD Diagnosis
According to research, ADHD in adults presents differently than in children, often manifesting as difficulties with organization, mood regulation, and impulsivity rather than hyperactivity alone (Kooij, 2012). Additionally, comorbid conditions such as anxiety, depression, and sleep disorders are common, further complicating diagnosis.
A valid diagnosis requires evidence that ADHD symptoms were present in childhood, persist into adulthood, and cause significant impairment in daily life (Kooij, 2012). This is why structured diagnostic interviews, such as the DIVA, play a crucial role in distinguishing ADHD from other conditions. Neuropsychological testing alone lacks the specificity to diagnose ADHD and should not be the sole basis for an assessment
Does an ADHD Diagnosis Guarantee Access to Medication?
It is important to clarify that undergoing an ADHD assessment does not automatically mean access to medication. In Australia, only a psychiatrist can prescribe medication for ADHD. If medication is something you wish to explore, the next step after receiving a diagnosis would be to discuss a referral to a psychiatrist who specializes in ADHD management.
Furthermore, research has shown that while stimulant medication is highly effective for many individuals, treatment should be multimodal, incorporating psychoeducation, coaching, and cognitive-behavioral therapy to address functional challenges (Kooij, 2012).
