Comprehensive Autism Assessment for Adolescents
Autism Spectrum Disorder (ASD) is a neurodevelopmental condition characterised by differences in social communication, sensory processing, emotional awareness, behavioural flexibility, and patterns of interests or routines. While some individuals are diagnosed during early childhood, many adolescents remain undiagnosed until later in life, particularly those who have developed effective coping strategies, masking behaviours, or present with more subtle autistic characteristics.
Adolescence is a period associated with increasing social demands, academic expectations, emotional complexity, and identity development. Undiagnosed autism during this stage may contribute to difficulties with friendships, social understanding, emotional regulation, sensory sensitivities, anxiety, self-esteem, and school functioning.
A comprehensive autism assessment can provide valuable insight into an adolescent’s neurodevelopmental profile, facilitate access to appropriate support, and assist families, schools, and healthcare providers in developing targeted interventions and accommodations.
Our adolescent ASD assessments are conducted by experienced psychologists using internationally recognised assessment instruments and evidence-based diagnostic approaches.
Assessment Options
Option 1 – Comprehensive Adolescent ASD Assessment
Fee: $600 (Inclusive of Psychological Report)
Assessment Administration
This assessment consists of:
60-Minute Clinical Interview
A psychologist conducts a detailed interview with the adolescent and parent(s).
Using MIGDAS / CARS structured clinical interview schedule.
Areas explored include:
- Developmental history
- Social communication patterns
- Peer relationships
- Sensory experiences
- Emotional regulation
- Restricted interests
- Repetitive behaviours
- School adjustment
- Family functioning
- Daily routines
- Mental health concerns
- Strengths and challenges
Online Assessment Battery
Following the interview, questionnaires are emailed for completion by the adolescent, parents, and teachers where applicable.
Assessment battery includes:
1. RBQ-3 (Self-Report)
2. RBQ-3 Informant Version (Parent Report)
3. AQ-Adolescent (Self-Report)
4. ASSQ (Parent Form)
5. ASSQ (Teacher Form)
6. ESQ-R (Self-Report)
7. MAIA-Y (Self-Report)
Why These Measures Were Selected
Autism in adolescence often presents differently from autism in early childhood. Many adolescents become increasingly aware of social expectations and may consciously adapt their behaviour to fit in with peers. As a result, a comprehensive assessment requires information from multiple informants and domains.
The selected assessment battery evaluates social functioning, repetitive behaviours, sensory experiences, emotional awareness, and internal experiences that are often overlooked in traditional autism assessments.
RBQ-3 (Repetitive Behaviour Questionnaire – Third Edition)
The RBQ-3 evaluates repetitive behaviours and restricted interests that form one of the core diagnostic domains of autism.
Areas assessed include:
- Ritualistic behaviours
- Repetitive movements
- Preference for routines
- Insistence on sameness
- Circumscribed interests
- Sensory-related repetitive behaviours
The inclusion of both self-report and informant versions provides a more comprehensive understanding of behavioural patterns.
AQ-Adolescent
The Autism Spectrum Quotient – Adolescent Version is designed to measure autistic traits among adolescents with average intellectual functioning.
It evaluates:
- Social communication
- Social understanding
- Flexibility of thinking
- Imagination
- Attention to detail
- Preferences for routines
Research suggests the AQ-Adolescent has good discriminative ability for identifying autistic traits among adolescents.
ASSQ
The Autism Spectrum Screening Questionnaire is among the most extensively researched screening tools for identifying autistic characteristics in school-aged children and adolescents.
Parent and teacher versions allow for comparison across environments.
Domains assessed include:
- Social interaction
- Communication
- Restricted interests
- Behavioural rigidity
- Emotional regulation
- Motor mannerisms
Multi-informant perspectives are particularly valuable because autism-related behaviours may present differently at home and in school settings.
ESQ-R
The ESQ-R assesses emotional self-awareness, emotional experiences, and aspects of emotional functioning relevant to autistic presentations.
Research increasingly recognises emotional processing differences as an important feature of autism in adolescents.
This measure contributes additional information regarding:
- Emotional insight
- Emotional awareness
- Emotional expression
- Internal experiences
MAIA-Y
The Multidimensional Assessment of Interoceptive Awareness – Youth Version evaluates body awareness and sensory experiences.
Many autistic adolescents report differences in interoceptive functioning, including awareness of:
- Hunger
- Fatigue
- Pain
- Stress responses
- Emotional sensations
- Physiological cues
Assessment of interoception provides clinically meaningful information that may influence emotional regulation and wellbeing.
Suitable For
Option 1 is recommended for:
- Adolescents suspected of having autism
- Teenagers experiencing social difficulties
- Youth with sensory sensitivities
- Students struggling with friendships or social communication
- Adolescents presenting with anxiety alongside possible autistic traits
- Families seeking a comprehensive and contemporary autism assessment
Benefits
- Broad multidimensional assessment
- Multiple informants included
- Sensitive to subtle autistic presentations
- Assesses sensory and emotional experiences
- Appropriate for adolescents with masking behaviours
- Cost-effective assessment pathway
Option 2 – Extended Comprehensive Adolescent ASD Assessment
Fee: $1,200 (Inclusive of Psychological Report)
Assessment Administration
Option 2 includes everything contained in Option 1 plus:
Autism Diagnostic Interview – Revised (ADI-R)
The ADI-R is a structured developmental interview conducted with a parent or caregiver.
The interview typically takes between 1.5 to 2.5 hours to administer.
Areas explored include:
- Early developmental milestones
- Language development
- Social communication history
- Childhood behaviours
- Restricted interests
- Repetitive behaviours
- Sensory experiences
- Functional impairment across developmental stages
How Option 2 Differs from Option 1
While Option 1 primarily focuses on current symptoms and contemporary autistic traits, Option 2 incorporates a detailed developmental investigation.
Autism is a neurodevelopmental condition that originates in early childhood.
The ADI-R assists clinicians in determining whether autistic characteristics were present throughout development and provides stronger historical evidence supporting diagnosis.
Suitable For
Option 2 is recommended for:
- Adolescents with available developmental history
- Families seeking greater diagnostic certainty
- Complex presentations
- Educational accommodation applications
- Cases involving diagnostic ambiguity
- Adolescents who may have developed compensatory or masking strategies
Benefits
- Includes all components of Option 1
- Enhanced developmental analysis
- Increased diagnostic confidence
- Stronger historical evidence
- Greater clinical depth
- Useful for educational planning and accommodations
Option 3 – Traditional Gold Standard Autism Assessment
Fee: $3,800 (Inclusive of Psychological Report)
Assessment Administration
This assessment consists of:
ADI-R
Structured developmental interview with parents or caregivers.
ADOS-2
Autism Diagnostic Observation Schedule – Second Edition
The ADOS-2 is a semi-structured observational assessment administered directly by a trained clinician.
It evaluates:
- Social reciprocity
- Communication
- Conversational abilities
- Emotional expression
- Imaginative capacities
- Restricted interests
- Repetitive behaviours
The assessment allows clinicians to directly observe autism-related behaviours in real time.
Why ADOS-2 and ADI-R Are Considered the Traditional Gold Standard
For many years, the combination of ADOS-2 and ADI-R has been considered the traditional gold standard approach to autism diagnosis.
The ADI-R provides detailed developmental information, while the ADOS-2 offers objective behavioural observation.
Together, these instruments allow clinicians to assess both historical and present manifestations of autism.
Research consistently supports the ADOS-2 as one of the most robust observational measures available for autism assessment.
Suitable For
Option 3 is recommended for:
- Complex clinical presentations
- Diagnostic uncertainty
- High-stakes educational applications
- Medico-legal assessments
- Disability support applications
- Families seeking the highest level of diagnostic rigour
Benefits
- Traditional gold-standard methodology
- Direct clinician observation
- Extensive developmental analysis
- High diagnostic confidence
- International recognition
- Comprehensive evaluation process
