An AuDHD assessment is a combined psychological evaluation for ADHD and Autism Spectrum Disorder (ASD). Conducted by a trained psychologist, it examines attention, social communication, behaviour, and emotional wellbeing to identify whether ADHD, ASD, or both are present, then provides tailored recommendations.
At Adelaide Clinical Psychology, we provide comprehensive AuDHD Assessment for Children and Adults using evidence-based methods to assess ADHD and ASD accurately. Because these two conditions often overlap, considering both together provides a clearer picture of how a person thinks, learns, and relates to the world around them. This guide explains what an AuDHD assessment involves, how it differs for children and adults, and what to expect at each stage of the process.
We take a holistic approach, considering developmental history and the environmental factors that shape how each person experiences and presents their challenges. The aim is a thorough assessment and practical support that reflects the individual, not a label alone.
What Is an AuDHD Assessment?
A combined assessment for ASD and ADHD is a psychological evaluation carried out by a trained psychologist. It reviews several areas at once, including:
- Cognitive functioning and attention
- Social communication and interaction
- Behavioural patterns and impulse control
- Emotional wellbeing and regulation
By examining these areas together, the psychologist can determine whether ADHD, ASD, or both are present. This matters because the two conditions frequently co-occur, and traits from one can mask or mimic traits from the other.
What Is ADHD?
ADHD, or Attention Deficit Hyperactivity Disorder, is a neurodevelopmental condition that affects attention, impulse control, and behaviour regulation. It presents differently from person to person. Some people are predominantly inattentive, others are more hyperactive and impulsive, and many experience a mix of both.
Common signs of ADHD include:
- Difficulty sustaining focus on tasks
- Frequent forgetfulness or losing things
- Acting impulsively without considering consequences
- Restlessness or difficulty sitting still
- Poor time management and planning
- Inconsistent performance across different tasks or settings
What Is ASD?
ASD, or Autism Spectrum Disorder, is a neurodevelopmental condition that reflects natural differences in how a person communicates, processes sensory information, and relates to others. It sits across a broad spectrum, so every individual has a distinct experience.
Common signs of ASD include:
- Differences in social communication and interaction
- A strong preference for routine and predictability
- Intense, focused interests
- Sensory sensitivities, such as to sound, light, or texture
- Difficulty interpreting social cues or unspoken rules
- Literal thinking and challenges with abstract language
What Is the Difference Between ADHD and ASD?
ADHD and ASD can look similar on the surface, yet there are clear differences between them. ADHD is mainly characterised by difficulties with attention regulation, impulse control, and executive function, which encompasses skills such as planning and organising.
ASD is defined more broadly by differences in social communication, sensory processing, and cognitive flexibility. The two conditions can co-occur, which is why assessing for both at the same time is often essential. A combined assessment helps ensure that nothing is missed and that any overlapping traits are properly understood.
What Does an AuDHD Assessment for Children Involve?
Children with ADHD or ASD are sometimes misunderstood as lazy, naughty, or shy when, in reality, they may be experiencing a neurodevelopmental condition. A thorough assessment gives families and educators a clear understanding of a child’s individual profile, which can guide support at home and at school.
Our psychologists work carefully to keep the assessment comfortable and reassuring for children. We explain each step and approach every child with warmth, patience, and care.
A child assessment typically covers:
- Cognitive ability and processing skills: attention, memory, and executive functioning skills such as planning, organisation, and flexible thinking.
- Attention and impulse control: difficulties with sustaining focus, managing impulses, and self-regulation.
- Social and emotional functioning: social communication, emotional regulation, and behaviour across home, school, and social settings.
- Autism-related traits and communication patterns: differences in social interaction, sensory sensitivities, and responses to the environment.
- Learning challenges (optional): screening for specific learning disorders such as dyslexia, dysgraphia, or dyscalculia.
What Does an AuDHD Assessment for Adults Involve?
Many adults spend years wondering why certain everyday tasks feel harder, or why they experience the world differently from those around them. A combined assessment for ADHD and ASD in adults looks at how these conditions show up across daily life, relationships, work, and emotional wellbeing.
We understand that seeking an assessment as an adult can feel like a significant step, so we approach the process with sensitivity and respect throughout.
An adult ADHD and ASD assessment looks at:
- Attention, concentration, and working memory: sustaining focus, managing information, and juggling multiple tasks.
- Adaptive functioning: everyday skills such as communication, independence, decision-making, and managing responsibilities.
- Functioning and task management: planning, organisation, time management, and following through on complex tasks.
- Emotional regulation and impulsivity: patterns of mood, stress response, and self-control.
- Social communication and interpersonal patterns: interactions, relationships, and social understanding.
- Sensory sensitivities and flexibility: how sensory input or unexpected change affects daily life.
- Developmental and historical review: childhood behaviours alongside current functioning across work, home, and social settings.
Why Combine Assessments for ADHD and ASD?
Assessing both conditions in one process is practical and efficient. Because ADHD and ASD traits can overlap, a combined assessment reduces the risk of one condition being overlooked. This approach provides:
- Fewer appointments and less disruption to school or work.
- A clearer understanding of how ADHD and ASD traits may overlap.
- A single, comprehensive report that addresses all areas of need in one place.
- Streamlined recommendations tailored to the person’s cognitive, behavioural, and social skills.
What Are the Steps in the Assessment Process?
We have designed our assessment process to be clear, supportive, and thorough. Here is what to expect from start to finish.
Step 1: Intake Call
The process begins with a welcoming intake call. Our Client Concierge takes time to understand your concerns and answer questions about the assessment. This call helps clarify whether an ADHD assessment, ASD assessment, or combined assessment is the right fit.
Step 2: Clinical Interview
A one-on-one interview with your psychologist builds a full picture of developmental history, current behaviours, and emotional wellbeing. For children, this interview is conducted with parents and covers early development through to current academic and social functioning.
Step 3: Testing and Assessment
Structured testing sessions form the core of the process. Depending on the assessment, this may include cognitive ability testing, executive function assessment, academic performance testing, and behavioural questionnaires. For children, teachers and parents also complete online screening tools to add context about behaviour across different environments.
Step 4: Comprehensive Report and Analysis
Once testing is complete, the psychologist analyses all collected data to identify patterns consistent with ADHD, ASD, or both. A detailed written report is then prepared, setting out the findings clearly with practical, tailored recommendations.
Step 5: Feedback Session
The final step is a feedback session with your psychologist. This is your chance to discuss the findings in full, ask questions, and understand what the results mean for you or your child.
