ADOS-2 Autism Testing: A Comprehensive Overview

ADOS-2 Autism Testing

How does ADOS-2 assess potential ASD indicators in my child’s behavior?

As parents, we often become skilled at identifying unusual behaviors in our children that may suggest a delay in developing specific skills, such as speech, social interaction, or eye contact. These behavioral indicators could potentially indicate the presence of autism, which makes it crucial for parents to be familiar with diagnostic tools like the ADOS-2 autism testing.

The Autism Diagnostic Observation Schedule-Second Edition (ADOS-2) is a standardized assessment tool by healthcare professionals and researchers. ADOS-2 evaluates social communication, interaction, and behavior in individuals suspected of having ASD, applicable to all ages beyond 12 months.

Now, you may ask yourself: How does ADOS-2 assess potential ASD indicators in my child’s behavior? Navigating the complexities of the neurodivergent world can be challenging, but ABA Centers of Tennessee is here to help. In this blog, we will provide beneficial insights. We present an in-depth exploration of what the ADOS-2 entails, its methods, and how it works to detect autism.

What is ADOS-2?

ADOS-2 autism testing is a comprehensive, standardized assessment tool specifically crafted to assist in diagnosing autism. Its primary function is to evaluate and observe the social and communicative behaviors of those suspected to be on the autism spectrum.

In the early 1990s, clinicians needed a more structured and reliable way to diagnose autism. As a response, they introduced the original ADOS. Over time, as research and clinical experience advanced, it became evident that the tool needed updates to enhance its accuracy and relevance.

In 2012, the second edition, ADOS-2, was published by experts, including Dr. Catherine Lord and Dr. Michael Rutter, incorporating revisions and improvements based on user feedback and advancements in our understanding of autism. This updated version offers a more comprehensive and nuanced approach to assessing individuals across different age ranges and developmental levels.

The National Library of Medicine has acknowledged the ADOS-2 as the premier method for evaluating communication skills, repetitive behaviors, and restricted interests in individuals suspected of having autism.

How does the ADOS-2 Autism Testing Work?

The ADOS-2 autism testing process involves a series of activities and interactions carefully designed to draw specific behaviors associated with ASD. Here’s an overview of how the ADOS-2 works:

1. Modules Based on Developmental Level:

The assessment consists of modules tailored to specific age groups and developmental levels. The module choice depends on the individual’s language abilities and chronological age.

2. Structured Activities:

It includes a set of standardized activities and social situations. These activities assess various aspects of social interaction, communication, and imaginative play. The examiner guides the individual through these activities, observing and documenting their responses.

3. Flexible Administration:

ADOS-2 autism testing allows for flexibility in administration to accommodate the individual’s unique characteristics and developmental level. The examiner may adapt some aspects of the assessment based on the person’s responses, ensuring a more accurate evaluation.

The examiner may provide drawing materials to observe nonverbal children’s communicative behaviors during a standard activity that usually involves verbal interaction.

4. Clinical Judgment:

In addition to the structured scoring, clinical judgment is crucial in the ADOS-2 assessment. Examiners consider the overall context of the individual’s behavior, considering cultural differences, comorbid conditions, and specific life experiences.

5. Interpretation and Diagnosis:

After completing the assessment, the examiner interprets the results with other clinical information. The information obtained from the ADOS-2 contributes to the diagnostic process, helping clinicians determine whether the individual meets the criteria for ASD.

Modules that Comprise the ADOS-2 Test

The ADOS-2 autism testing consists of four modules tailored to individuals with varying communication abilities and developmental stages. Each module evaluates social interaction, communication skills, and behavioral responses. Let’s explore the unique features of each module:

  • Module 1: This module is tailored explicitly for nonverbal individuals with limited speech capabilities. This module emphasizes enhancing communication and fostering social interaction through play-based and structured activities.
  • Module 2:  for individuals with phrase speech capabilities. This module strongly emphasizes advancing communication skills and promoting social interaction, tailoring activities to align with the individual’s language level.
  • Module 3:Tailored for individuals five years and older verbal fluency. Module 3 comprehensively evaluates communication skills and social interaction abilities. The primary goal is to refine and optimize the communication capabilities of those who have already achieved verbal fluency.
  • Module 4: Facilitating adolescents and adults who display verbal fluency; this module involves a clinician engaging with verbally fluent individuals. The assessment includes a conversation to observe social interactions, explore topics of interest, and evaluate the individual’s grasp of nonverbal cues. Moreover, activities are incorporated to stimulate imaginative thinking, offering insights into flexibility and abstract reasoning.

As this assessment aims to observe the child’s performance independently, parents cannot intervene and assist their child. Some examiners opt to exclude parents from the evaluation, as the strong desire of parents to aid their child may occasionally become a distraction for the child during the assessment.

What to Expect of the ADOS-2 Autism Testing

Besides the ADOS-2, many providers conduct a thorough evaluation that involves family and caregiver interviews. During these interviews, the clinician gathers information about the child’s medical and developmental history, age, areas of delay, standardized measures, and specific parental concerns. Some doctors and agencies complete this evaluation in a single session.

Unaware of the individual’s history, symptoms, or behavior, a professional typically conducts the ADOS-2 assessment, taking between 30 and 60 minutes. The clinician must decide which module to use, and sometimes, they may change it in the evaluation if it no longer aligns with the individual’s functional capabilities. While evaluating the child, the doctor may ask the parent to be present during the review session. In this case, parents should observe objectively and interact with the child only if the doctor requests it.

Following the session, the clinician discusses the assessment with the client’s family, often assessing and sharing the scores during the same appointment. However, some providers may suggest scheduling a follow-up appointment to review the results. This follow-up session provides an ideal opportunity for parents to ask questions. Finally, parents receive a comprehensive written report with recommendations within two weeks.
