ADHD & Autism Assessment

 I provide comprehensive diagnostic assessments for Autism and ADHD in adults (18+). These assessments are thorough, evidence-based, and designed to provide clarity, understanding, and practical next steps.

Because Autism and ADHD commonly co-occur, I assess for both conditions as standard practice. There is no additional charge for dual assessment.

​

What the Assessment Involves

​

1. Comprehensive Diagnostic Interview (up to 3 hours)

​

A detailed exploration of your:

​

  • Developmental history

  • Childhood presentation

  • Current strengths and challenges

  • Educational, occupational, and relational experiences

  • Sensory profile and executive functioning patterns

​

Where appropriate, collateral information may also be considered.

​

2. Standardised Assessment Measures

​

Prior to your appointment, you will complete structured online questionnaires and intake forms.

​

These must be returned at least 1–2 weeks before your diagnostic session to allow adequate time for scoring and preparation.

These measures assess areas such as:

​

  • Attention and executive functioning

  • Social communication

  • Sensory processing

  • Emotional regulation

  • Functional impact across settings

 

3. Comprehensive Diagnostic Report

​

You will receive a detailed written report outlining:

​

  • The assessment process

  • The diagnostic criteria considered

  • How criteria are met (or not met)

  • Results from all assessment tools used

  • Clear explanations in accessible language

  • Helpful graphs to visually present findings

  • Brief, individualised recommendations

​

The report may be used to support workplace or university accommodations and can be shared with your GP or psychiatrist if required.

​

4. Feedback Session (50 minutes)

​

A dedicated session to:

​

  • Discuss your results

  • Answer your questions

  • Clarify recommendations

  • Explore next steps

​

​

Not Sure if a Full Assessment Is Right for You?

​

If you are unsure whether a comprehensive diagnostic assessment is what you need, you may choose to book a pre-assessment consultation.

​

This session provides an opportunity to:

​

  • Discuss your current concerns

  • Clarify your goals

  • Explore whether a diagnostic assessment is appropriate

  • Determine the most suitable next steps

​

There is no obligation to proceed to a full assessment following this consultation.

​

Cost of this consultation is $250.

Important Information About NDIS

While I provide detailed and high-quality diagnostic reports, this service is not designed specifically for NDIS access.

​

The NDIS considers additional factors beyond diagnosis, including functional capacity. If your primary goal is accessing the NDIS, I recommend engaging a service that provides NDIS-specific diagnostic assessments and reports.

​

Scope of Service

​

  • Assessment-only service (ongoing therapy option depending on availability)

  • I do not prescribe medication

  • If seeking medication following an ADHD diagnosis, you will need to consult a psychiatrist

  • I am unable to provide psychiatrist referrals (please obtain a referral via your GP)

  • Communication is primarily via email

​

Crisis Support

​

Casuarina Holistic Psychology is not a crisis service.

If you are in immediate distress or require urgent support, please contact emergency services by dialling 000 (Australia) or Lifeline 13 11 14
