The Diagnosis Process

The evaluations below are the "gold-standard" evaluations used to make a formal diagnosis of ASD. We’ll also request your child's medical records from your child’s healthcare providers.  A physician will then use all this information to make a formal diagnosis.

A formal diagnosis is required by an insurance company before they will pre-authorize any ABA therapy benefits relating to Autism Spectrum Disorder.  Our goal at AB Spectrum is to simplify the access to care for our clients – that’s why we offer assessments, diagnosis, as well as help communicating with the insurance company on your behalf.

 

Autism Diagnostic Observation Schedule, Second Edition (ADOS-2)

The Autism Diagnostic Observation Schedule, Second Edition (ADOS-2) is a semi structured, standardized assessment of a person’s communication, social interaction, play, and restricted and repetitive behaviors that can be used to assess and diagnose autism spectrum disorders. The ADOS-2 can be used in children as early as 12 months old through adulthood, and across a variety of developmental levels and language skills. The ADOS-2 takes approximately 40-60 minutes to administer and provides cutoff scores for autism and autism spectrum classifications as well has a Comparison Score indicating a level of autism spectrum related symptoms compared to same-age children with ASD that have similar language skills.

 

Autism Diagnostic Interview – Revised (ADI-R)

The Autism Diagnostic Interview – Revised (ADI-R) is a comprehensive interview composed of 93 items focusing on a person’s language/communication, reciprocal social interactions, and restricted, repetitive, and stereotyped behaviors and interests. The ADI-R provides categorical results that can be used to support a diagnosis of autism or to determine the clinical needs of various groups in which a high rate of autism spectrum disorders might be expected. The ADI-R is administered by an experienced clinical interviewer to a parent or caretaker familiar with the developmental history and current behavior of the individual being evaluated. The interviewer records and codes the informant’s responses, following highly standardized procedures. The ADI-R interview questions cover eight content areas:

  • the subject’s background, including family, education, previous diagnoses, and medications

  • overview of the subject’s behavior

  • early development and developmental milestones

  • language acquisition and loss of language or other skills

  • current functioning in regard to language and communication

  • social development and play

  • interests and behaviors

  • clinically relevant behaviors, such as aggression, self-injury, and possible epileptic features

The ADI-R allows the interviewer to calculate and interpret any one of five age-specific algorithms. There are two Diagnostic Algorithms based on developmental history and used for formal diagnosis and three Current Behavior Algorithms focusing on present functioning and used for treatment and educational planning.

 

Childhood Autism Rating Scale, (CARS-2) Second Edition

The Childhood Autism Rating Scale, Second Edition (CARS-2) is a rating scale completed by a clinician with information from an unscored Parent/Caregiver Questionnaire. The CARS-2 helps identify children with autism and determine symptom severity through quantifiable ratings based on direct observation. The CARS-2 addresses the following functional areas (depending on age/functioning level):

  • relating to people

  • imitation or social emotional understanding

  • emotional response or emotional expression and regulation of emotions

  • body use

  • object use or object use in play

  • adaption to change or adaptation to change/restricted interests

  • visual response

  • listening response

  • taste/smell, and touch response and use

  • fear or nervousness or fear or anxiety

  • verbal communication

  • nonverbal communication

  • actively level or thinking/cognitive integration skills

  • level and consistency of intellectual response

  • general impression
