Autism Assessment and Resources to Diagnose Autism

Autism Assessment and Resources to Diagnose Autism

There are several different Autism assessment tools available for doctors and other professionals.  I have put together a list of autism assessment tools and an explanation for each one.

Autism Assessment Tools

Autism Diagnostic Interview – Revised

The Autism Diagnostic Interview-Revised (ADI-R) is a structured interview conducted with the parents of individuals who have been referred for the evaluation of possible autism or autism spectrum disorders. The interview, used by researchers and clinicians for decades, can be used for diagnostic purposes for anyone with a mental age of at least 18 months and measures behavior in the areas of reciprocal social interaction, communication and language, and patterns of behavior – wikipedia

Prelinguistic Autism Diagnostic Observation Schedule (Autism Assessment tool for nonverbal children)

The Pre-Linguistic Autism Diagnostic Observation Schedule (PL-ADOS) is a semistructured observation scale designed for use as a diagnostic tool for children less than 6 years old who are not yet using phrase speech and are suspected of having autism. The PL-ADOS takes approximately 30 minutes to administer and is appropriate for use with this population because of its emphasis on playful interactions and the use of toys designed for young children. Reliability studies indicated that both individual activity ratings and summary ratings could be reliably scored from videotaped assessments by naive raters. Additionally, PL-ADOS scores of nonverbal preschool-aged children referred for clinical diagnosis and classified on the basis of a diagnostic team’s clinical judgment, clearly discriminated between autistic and nonautistic developmentally disabled children. The resulting diagnostic algorithm is theoretically linked to diagnostic constructs associated with ICD-10 and DSM-IV criteria for autism. – NCBI

Childhood Autism Rating Scale

The Childhood Autism Rating Scale (CARS) helps to identify children (2 years and older with Autism, specifically, distinguishing them from developmentally handicapped children who are not Autistic. In addition, it distinguishes between mid-to-moderate and severe Autism. Its brevity makes it a very useful tool to help you recognize and classify Autistic children.

Now the CARS2 expands the test’s clinical value, making it more responsive to individuals on the “high functioning” end of the Autism Spectrum—those with average or higher IQ scores, better verbal skills, and more subtle social and behavioral deficits. While retaining the simplicity, brevity, and clarity of the original test, the CARS2 adds forms and features that help you intergrate diagnostic information, determine functional capabilities, provide feedback to parents, and design targeted intervention. -MHS

Autism Behavior Checklist ( Autism Assessment tool that can be used by parents )

The Autism Behavior Checklist (ABC) is a list of questions about a child’s behaviors. The ABC was published in 1980 (Krug et al., 1980) and is part of a broader tool, the Autism Screening Instrument for Educational Planning (ASIEP) (Krug et al., 1978). The ABC is designed to be completed independently by a parent or a teacher familiar with the child who then returns it to a trained professional for scoring and interpretation. Although it is primarily designed to identify children with autism within a population of school-age children with severe disabilities, the ABC has been used with children as young as 3 years of age. -Health.NY

Checklist for Autism in Toddlers ( Autism Assessment designed to identify risk of Autism at a young age)

The Modified Checklist for Autism in Toddlers (M-CHAT™) is a scientifically validated tool for screening children between 16 and 30 months of age to assess their risk for autism spectrum disorder (ASD). It was developed by neuropsychologists Diana Robins and Deborah Fein and clinical psychologist Marianne Barton.  -AutismSpeaks

Real Life Rating Scale

The Real Life Rating Scale (RLRS) (Freeman, Ritvo, Yokota, & Ritvo, 1986) is a scale used to assess the effects of treatment on 47 behaviors in the motor, social, affective, language, and sensory domains among autistic persons. The RLRS is applicable in natural settings by nonprofessional raters, is rapidly scored by hand, and can be repeated frequently without affecting inter-observer agreement. Data are presented on inter-rater agreement among novice and experienced observers. Instructions for the scale, target behaviors, and definitions are appended to the journal article. -Behavior Consultant

Pervasive Developmental Disorder Screening Test

This easily administered tool is designed to screen for several autistic spectrum disorders in children as young as 18 months, including autistic disorder, pervasive developmental delay, and Asperger’s disorder. – Pearson Assessments

Autism Screening Instrument for Educational Planning (2nd ed.)

The Autism Screening Instrument for Educational Planning—Third Edition (ASIEP-3) is a valid and reliable measure of autism and related behaviors. It was designed to identify individuals with autism; assist in planning appropriate educational programs for those individuals; monitor performance and progress; and research autism.  -Mayer-Johnson

Diagnostic Checklist for Behavior-Disturbed Children (Form E-2) (Autism Assessment tool for parents)

Form E-2 is a questionnaire for parents of autistic-spectrum children. It was developed by Dr. Bernard Rimland, director of the Autism Research Institute. It’s important to understand that Form E-2 is not a diagnostic tool per se. Its purpose is to build a large, detailed database on autism-related symptoms and behaviors. By copying this checklist, filling it out, and mailing it to ARI, you will be assisting with the longest-running research project on the topic of ASDs. -Patient Centers

Gilliam Autism Rating Scale

The GARS-2, a revision of the popular Gilliam Autism Rating Scale, is a norm-referenced instrument that assists teachers, parents, and clinicians in identifying and diagnosing Autism in individuals ages 3 through 22, and in estimating the severity of the child’s disorder. Normed on a representative sample of 1,107 persons with Autism from 48 states, the instrument consists of 42 clearly stated items describing the characteristic behaviors of persons with Autism. The items are grouped into three subscales: Stereotyped Behaviors, Communication and Social Interaction.  -Mayer-Johnson
