At a Glance
Use the links below to move quickly through each stage of the assessment process.
Initial Enquiry & Registration
Once you contact Lycali, our team will review your enquiry and provide information about the most appropriate combined autism and ADHD assessment pathway based on your needs.
If you decide to proceed, you will be sent a registration form to complete. This allows us to gather key information about you and register you securely on our clinical management system.
The registration form includes information such as your contact details, GP details, relevant background information and consent preferences.
Invoice, Terms & Conditions and Consent
Once registered, we will issue your assessment invoice together with our terms and conditions and consent documentation.
These documents must be reviewed and signed before your assessment can proceed.
Payment Received
Once payment has been received and all documentation has been completed, your assessment pathway will formally begin.
You will then receive access to the required pre-assessment questionnaires and any additional screening documents needed for your assessment.
Documents to Complete
Please complete the forms below before your appointment. These help us gather information about your developmental history, communication profile, social interaction, attention, executive functioning, emotional regulation, sensory experiences and day-to-day functioning.
Adult Developmental History Questionnaire
This questionnaire helps us understand your developmental history, childhood experiences, education, relationships, communication profile, sensory experiences, attention and daily functioning.
Combined Autism & ADHD Add-On Questionnaire
This questionnaire gathers additional information regarding autism and ADHD-related experiences, including social communication, sensory processing, masking, attention, impulsivity, executive functioning, emotional regulation and daily life.
Informant Information
As part of your combined autism and ADHD assessment, we ask for information from someone who knows you well. This person is referred to as an informant.
Informants help us build a fuller picture of developmental history, childhood experiences, social communication, attention, organisation, behaviours, interests, sensory experiences and day-to-day functioning.
Suitable informants may include:
- A parent who can provide childhood developmental history
- Both parents together
- A partner or spouse
- A sibling or close family member
- A close friend who has known you for many years
- A combination of a parent and partner where appropriate
The adult being assessed may also attend the developmental history interview where appropriate.
If you are unsure who would be the most suitable informant, please contact the Lycali team for advice before completing the forms below.
Adult Neurodevelopmental Informant Questionnaire
Please ask your chosen informant to complete this questionnaire. The information provided will support both the autism and ADHD components of the assessment.
This questionnaire should be completed by the informant and not by the person being assessed.
Informant Availability Form
Please ask your chosen informant to complete the availability form below so that we can arrange the separate ADI-R or developmental history interview.
This form should be completed by the informant and not by the person being assessed.
Additional Screening Questionnaires
If you have already completed a neurodevelopmental pre-screening assessment with Lycali, you may not need to complete some of the questionnaires again unless requested by a clinician.
As part of your assessment, you may be asked to complete:
- Adult AQ-50
- Adult ASRS
- Adult SDQ
- Wender Utah Rating Scale (WURS)
These questionnaires will be sent separately to your email address. Please check your inbox, junk mail and spam folders regularly.
Assessment Appointments
Combined Autism and ADHD assessments are completed across multiple assessment appointments. This allows clinicians to gather information regarding both developmental history and current presentation, ensuring a comprehensive and evidence-based assessment process.
The first stage of the assessment process focuses on understanding your developmental history, childhood experiences, education, relationships, communication profile, attention, organisation, executive functioning, emotional regulation, sensory experiences and day-to-day functioning.
This stage of the assessment may include:
- DIVA-5 (Diagnostic Interview for ADHD in Adults)
- ADI-R or equivalent developmental history interview
- Review of screening questionnaires and background information
- Discussion regarding current strengths, challenges and support needs
Who should attend?
The adult being assessed should attend the DIVA assessment.
For the ADI-R or developmental history interview, we strongly encourage the attendance of an informant who knew the individual well during childhood, ideally a parent.
Where a parent is unavailable, another family member, sibling, long-term caregiver or other individual who can provide reliable developmental information may be suitable.
The adult being assessed may also attend the developmental history appointment where appropriate.
The ADOS-2 appointment forms part of the autism assessment pathway and is completed separately to the developmental history and ADHD assessment components.
During this appointment, the clinician will explore communication, social interaction, social understanding, sensory experiences, interests, routines, flexibility of thinking and day-to-day functioning through a structured assessment process.
Who should attend?
The adult being assessed should attend the ADOS-2 appointment.
Informants, partners or supporters do not usually need to attend unless this has been agreed in advance with the clinician.
ADOS-2 appointments may be completed:
- Face-to-face at one of Lycali's clinic locations; or
- Online using an alternative validated autism assessment pathway where clinically appropriate.
Information gathered from questionnaires, screening measures, informants, developmental history interviews, the DIVA assessment and autism assessment observation will all be considered as part of the multidisciplinary diagnostic decision-making process.
The Lycali administration team will contact you to arrange suitable appointment dates and will confirm who needs to attend each stage of the assessment process.
Report, Feedback and Recommendations
Following completion of the assessment, the clinical team will review and analyse all information gathered throughout the process.
You will receive a comprehensive written report summarising:
- Assessment findings
- Clinical observations
- Information gathered from questionnaires and informants
- Diagnostic conclusions where appropriate
- Strengths and areas of need
- Recommendations and next steps
Recommendations may include workplace adjustments, reasonable adjustments, therapy, coaching, sensory supports, psychoeducation, Access to Work support, medication referral pathways and post-diagnostic resources.
What Happens After Diagnosis?
Following assessment, you may wish to access additional support, coaching, therapy, workplace adjustments, psychoeducation, sensory strategies or autism and ADHD-specific resources.
Lycali has created a dedicated page to help you understand possible next steps after diagnosis.
If you are unsure which forms to complete, require assistance accessing documentation, or would like advice regarding a suitable informant, please contact the Lycali team.
