It is not uncommon for a neurodivergent person to meet the established diagnostic criteria for both ADHD and Autism (ASD). Establishing the presence of all relevant diagnoses increases the likelihood that a person will have access to all appropriate treatments and accommodations.
We conduct the assessment as a two-step process:
1. Screening
2. Diagnostic Assessment
We offer our Combined ADHD + Autism assessment service as a two-step process as it allows us to provide a thorough initial screening without clients incurring the costs of a full evaluation if they are unlikely to meet diagnostic criteria for ADHD and/or Autism.
To proceed with any of the Combined ADHD + Autism assessment options, you will need to purchase the Combined ADHD + ASD Screening Assessment service first.

Assessment Process
1. Screening
- Screening Assessment
Once you have paid for the screening assessment, and completed the registration form, links to the screening forms will be sent to you and the person or people you nominated to gather collateral information.
Collateral Information
You will be asked to fill in a registration form with your personal details, as well as the names and contact details of people who know you well, both now and as a child. This is referred to as collateral information and is required to proceed with our services.
Why do we collect Collateral Information?
To ensure all ADHD diagnostic criteria are met, collateral support of both current and childhood symptoms is required.
The information from collateral sources is typically gathered using questionnaires that will be sent directly to the nominated person(s).
Current Symptoms
- Collateral information about your current symptoms can be provided by anyone who knows you well now.
Childhood Symptoms
- Collateral information about childhood symptoms can come from
- Caregivers
- Parents
- Siblings
- Extended family or
- Anyone who knew you well enough to report on your symptoms during childhood (before age 12 years).
- School reports can also be helpful in documenting childhood symptoms and difficulties.
- Review of Screening Assessment
Once all the screening forms have been completed, the information submitted will be reviewed by a registered psychologist and you will be provided with feedback about whether the information that is submitted supports the pursuit of a formal diagnostic assessment.
You will receive an email from our team with instructions on the next steps to take
2. Diagnostic Assessment
- Appointment
We can offer appointments within 1-2 weeks after the screening forms have been completed and reviewed.
The diagnostic assessment interview usually takes about an hour, and is used to follow up on responses from the completed screening forms and to gather additional information about the person's history and any other potential causes of the person's difficulties, including other mental health conditions.
- Diagnosis
The diagnosis of ADHD / Autism in adults is determined by the answers to four key questions:
- Does the person have symptoms and difficulties that are consistent with ADHD / Autism?
- Is there evidence that those symptoms and difficulties were present during childhood?
- Are the symptoms and difficulties associated with impairment across multiple settings?
- Is there a better explanation for the person's symptoms and difficulties? (e.g., head injury, chronic insomnia, or other acute mental health conditions).
- Diagnostic Report
After the forms are completed and the diagnostic assessment interview has taken place, a report is generated that includes any appropriate diagnoses and treatment recommendations.
We aim to have the report ready within 10 business days of the assessment and you will receive a notification via email once it is available.
- Prescriptions
Our team does not prescribe stimulant medication. Instead, we apply for special authority and then refer you back to your GP who will then be responsible for initiating your medication and providing ongoing prescriptions.
- Medication Changes
Medication changes due to ineffectiveness or side effects
As part of our duty of care, our clinical team is available for GPs to consult with regarding medication changes, side effect management, or alternative medication options.We are happy to provide ongoing support to ensure patients find the most suitable treatment plan.
To change medication
Your doctor will need to send us a referral with the following information:
- Medication/s that have been trialed

- Why we refer back to GPs after diagnosis
After diagnosis, clients will be referred back to their GP for application of special authority, initiating medication and providing ongoing prescriptions for several reasons:
- In-person medical evaluation: Because our service is online-only, we need GPs (or nurses) to conduct any required physical examinations.
- Cost-effectiveness: It's more affordable for clients to see their GP for prescriptions and for follow-up appointments, rather than a psychiatrist.
- Limited psychiatric resources: Due to the limited availability of psychiatrists in New Zealand, having GPs manage the special authority and ongoing care of clients enables us to utilize the psychiatrist's expertise more resourcefully. This strategic allocation of psychiatric resources enables more patients to benefit from specialist care.
- Medication prescriptions: For certain medications, like stimulants for ADHD, GPs need special authority to prescribe. We will apply for special authority and then ask the GP to initiate and manage medication treatment. This process ensures clients receive comprehensive primary care support, and allows us to help more clients efficiently.
- In-person medical evaluation: Because our service is online-only, we need GPs (or nurses) to conduct any required physical examinations.
