Combined ADHD + Autism Assessment for individuals 16+

---

Katrina is a client-focused, holistic psychologist who works with children, adolescents, and adults, supporting people to heal in ways that honour the whole person. Her approach is neuro-affirming and trauma-informed, recognising that mental health is shaped by the interaction of development, environment, lived experience, biology, and relationships — rather than by deficits or labels.

Katrina believes that neurodivergence is not something to be fixed, but an existence to be understood, supported, and respected. Her assessments are thorough, practical, and compassionate, grounded in evidence-based methods while remaining flexible to each individual’s unique neurodivergent profile, strengths, and needs.

Outside the therapy room, Katrina is a mum to three energetic boys, an ocean-lover, and an animal enthusiast with a soft spot for horses. She also shares her workspace with a therapy bird, who occasionally steals the show and reminds everyone to slow down, stay curious, and breathe.

Katrina believes that healing happens best when people feel seen, supported, and empowered to be exactly who they are. In line with this belief, she designed and piloted a low-income assessment program across Gippsland, providing individuals and families experiencing financial hardship with access to psychological services and thorough diagnostic support. Over its six-month pilot, the program achieved outstanding results. 

In partnership with Peninsula Wellness & Therapy, the program’s diagnostic component has now been expanded Australia-wide, offering combined ADHD and Autism assessments. This ensures that everyone, regardless of socio-economic status, can access thorough and professional diagnostic services.

Please note you DO NOT need a referral from your GP for an assessment. Simply follow the instructions below:

1. Book Your Session

You’ll begin by logging into our secure online booking portal to choose a date and time that suits you. This appointment is a 1:1 Telehealth (online) ADHD & Autism Assessment with Katrina.

The total cost of the combined assessment is $900. A non-refundable $200 deposit is required at the time of booking to secure your session. The remaining $700 will be invoiced and is due one week prior to your appointment.

Payment options:

• Afterpay for remaining balance: You can use Afterpay for the $700 balance. Please note there is an additional processing fee of $47. Email admin@peninsulawellnessandtherapy.com if you would like to arrange this.
   
• Afterpay for full assessment: If you would like to use Afterpay for the full $900 assessment, an additional processing fee of $59 applies. Please email admin@peninsulawellnessandtherapy.com to set this up.

2. Complete Some Pre-Session Forms
Once your booking is confirmed, you’ll receive an email with a developmental history form and a series of questionnaires. These forms invite you to reflect on your experiences across different stages of life, including childhood, adolescence, and adulthood, as well as your current strengths, challenges, and day-to-day functioning.

These forms need to be completed at least one week before your 1:1 session. Taking the time to complete them thoughtfully allows your clinician to review your responses in advance, identify key patterns, and prepare for your assessment. This means your session can focus on deepening understanding, clarifying important details, and exploring your experiences in context, rather than gathering basic information. Completing the forms ahead of time supports a more accurate, respectful, and clinically sound assessment process.

3. Attend Your 1:1 Online Assessment
Although developmental history forms and questionnaires are completed prior to your appointment, the 1:1 Telehealth session is where this information is clinically explored, clarified, and interpreted. 

During the session, Katrina will guide you through a structured assessment process that examines patterns across your lifespan, links your developmental history to current functioning, and explores traits commonly associated with ADHD and Autism in context. This includes clarifying questionnaire responses, exploring onset and persistence of traits, and making real-time clinical observations. This step is essential for ensuring the assessment is accurate, ethical, and based on a comprehensive understanding of your experiences rather than questionnaires alone. 

4. Receive Your Full Report
About 6–8 weeks after your session, you’ll receive a comprehensive report summarising the assessment findings and recommendations. This report can be used to support psychiatric appointments, guide therapy or coaching, and help plan any other supports that meet your needs.

No, a psychologist cannot prescribe medication. Psychologists focus on providing evidence-based therapies, assessments, and support for mental health and wellbeing. If medication is something you wish to explore, this will need to be done in collaboration with a medical professional such as a psychiatrist. They can assess whether medication may be helpful for your symptoms and provide ongoing monitoring if it’s prescribed. Psychologists often work alongside these professionals to ensure that therapy and any medication support each other for the best outcomes.

This combined ADHD and Autism assessment, conducted by a psychologist, is suitable for anyone who suspects they may have ADHD, Autism Spectrum Disorder (ASD), or both. It is particularly helpful for adults who have experienced lifelong difficulties with attention, focus, social communication, executive functioning, or sensory processing, and want a clearer understanding of their neurodevelopmental profile. The assessment can also support access to tailored strategies, therapy, or accommodations at work, study, or in daily life. 

If criteria for ADHD and/or Autism are met, Katrina will provide a formal diagnosis and diagnostic report. Even if you do not meet full criteria, the assessment will clarify your profile and highlight strategies or supports that may benefit you. 

Yes. The cost remains the same. 

When making your booking you can select from the following 3 options: 

• Combined ADHD + Autism Assessment
• Autism Assessment only
• ADHD Assessment only.

This is a conscious choice we have made for our practice. We are deeply aware that the cost of ADHD and Autism assessments has become a significant barrier for many people, often placing essential diagnostic support out of reach.

We believe that clarity, validation, and appropriate recommendations should not be reserved only for those who can afford several thousand dollars. Our aim is to reduce financial stress while still delivering a comprehensive, evidence-based assessment that meets professional and ethical standards.

The assessment provides clarity about your cognitive, emotional, and behavioural patterns. It helps you understand your strengths, challenges, and strategies to improve daily functioning, manage symptoms, and access appropriate supports at work, study, or in personal life. 

No. This assessment is for individuals aged 16 years and over only. 

No. There is no Medicare rebate available for this assessment. 

Assessment sessions are non-refundable. Time is reserved specifically for you, and significant preparation, administration, and scoring are completed in advance.

Cancellations require a minimum of 7 days notice. If less than 7 days notice is provided, your deposit will be forfeited. If you need to reschedule please provide a minimum of 48 hours notice to do so.
