More on Autism Testing
Here is an alternate list or view of autism assessments and screening tools commonly used in clinical, educational, and research settings. These tests vary in purpose (diagnosis, screening, or trait identification) and age range.
1. Diagnostic Tools
(Gold Standard)
Autism Diagnostic Observation Schedule (ADOS-2)
Purpose: Observational assessment of social communication and repetitive behaviors.
Ages: Toddlers to adults.
Autism Diagnostic Interview-Revised (ADI-R)
Purpose: Structured interview with caregivers about developmental history and behaviors.
Ages: Children and adults (via retrospective reporting).
Diagnostic and Statistical Manual (DSM-5/ICD-11) Criteria
Purpose: Clinical diagnosis based on standardized behavioral criteria.
2. Screening Tools
(used before Diagnostic Tools)
Modified Checklist for Autism in Toddlers (M-CHAT-R/F)
Ages: 16–30 months.
Purpose: Early screening for toddlers.
Social Communication Questionnaire (SCQ)
Ages: 4+ years (caregiver-reported).
Autism Spectrum Quotient (AQ)
Ages: Teens/adults (self-report or caregiver-report).
Variants: AQ-10 (short), AQ-Child.
Social Responsiveness Scale (SRS-2)
Ages: 2.5+ years.
Purpose: Measures social communication traits.
Childhood Autism Rating Scale (CARS-2)
Ages: 2+ years.
Purpose: Rates observable behaviors.
Autism University is composed of two main sections: Defintions of Autism and the 5 Views of Autism. Below you will find future topics listed out in no partiular order at this time.
-
Echolalia
-
Scripting
-
Gestalt Processing

3. Adult-Focused Assessments
Ritvo Autism Asperger Diagnostic Scale (RAADS-R)
Purpose: Self-report for adults.
Focus: Lifetime traits (not just current symptoms).
Camouflaging Autistic Traits Questionnaire (CAT-Q)
Purpose: Measures masking behaviors in adults.
Adult Repetitive Behaviours Questionnaire (RBQ-2A)
Focus: Restricted/repetitive behaviors.
4.Emerging or Alternative Tools
Monotropism Questionnaire
Focus: Attention patterns linked to autism.
Autism Symptom Dimensions Questionnaire (ASDQ)
PDA (Pathological Demand Avoidance) Tools (e.g., EDA-Q).
Key Notes
-
No single test is definitive—diagnosis requires a multidisciplinary approach (history, observation, and testing).
-
Self-report tools (e.g., AQ, RAADS-R) screen for traits but can’t replace clinical evaluation.
-
Cultural bias: Some tools lack validation for marginalized groups (e.g., BIPOC, gender-diverse individuals).
Who can use the DSM-5 manual to diagnose autism?
In the United States, the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, 5th Edition) is the standard reference for diagnosing autism spectrum disorder (ASD). Only licensed healthcare professionals with specialized training in neurodevelopmental or mental health disorders are authorized to use the DSM-5 to formally diagnose autism. Here’s a breakdown of qualified providers:
1. Independent Diagnosticians (Can Diagnose ASD Alone)
These professionals are fully licensed to diagnose autism using the DSM-5:
Psychiatrists (MD/DO) – Medical doctors specializing in mental health and developmental disorders.
Developmental Pediatricians (MD/DO) – Pediatricians with advanced training in autism and related conditions.
Child Neurologists (MD/DO) – Neurologists focusing on developmental brain disorders.
Clinical Psychologists (PhD/PsyD) – Licensed psychologists trained in ASD assessment tools (e.g., ADOS-2, cognitive testing).
Neuropsychologists (PhD/PsyD) – Specialize in brain-behavior relationships, often diagnosing complex ASD cases.
2. Clinicians Who May Diagnose Under Supervision or in Teams
These providers may contribute to evaluations but typically cannot diagnose ASD independently unless explicitly allowed by state law or under supervision:
Licensed Clinical Social Workers (LCSW) – May assist in evaluations but usually require collaboration with a psychiatrist/psychologist for a formal DSM-5 diagnosis.
Licensed Professional Counselors (LPC/LMHC) – Similar to LCSWs; must work with a diagnosing physician.
Advanced Practice Nurses (Psychiatric NPs) – Can diagnose in some states but may need physician oversight.
3. Providers Who Contribute to Assessments but Cannot Diagnose
These professionals play a role in evaluations but cannot issue a standalone DSM-5 ASD diagnosis:
Speech-Language Pathologists (SLP) – Assess communication deficits but lack diagnostic authority.
Occupational Therapists (OT) – Evaluate sensory/motor issues but cannot diagnose ASD.
School Psychologists – Use educational criteria (e.g., IDEA) for school services but cannot provide a medical diagnosis.
Key Requirements for a Valid DSM-5 ASD Diagnosis
-
Must use DSM-5 criteria (e.g., persistent deficits in social communication + restricted/repetitive behaviors).
-
Often paired with standardized tools (e.g., ADOS-2, ADI-R, M-CHAT).
-
Must be licensed in their state to diagnose mental/developmental disorders.
Important Notes
Insurance & Legal Recognition:
For insurance coverage (e.g., Medicaid, private plans) or disability services, a diagnosis must come from a licensed physician (MD/DO) or psychologist (PhD/PsyD) in most cases.
State Variations:
Some states grant broader diagnostic authority to nurse practitioners or clinical social workers. Always verify with your state licensing board.
