Understanding the ADOS: What to Expect During Your Child's Autism Evaluation

If your child is undergoing an autism evaluation, you may hear about the ADOS or Autism Diagnostic Observation Schedule. The ADOS is considered the "gold standard" assessment tool used by professionals worldwide to diagnose Autism Spectrum Disorder (ASD), and is required to be used during the assessment. Let's talk about what you can expect during the evaluation with your child so you can feel more at ease about it!

What Is the ADOS?

The Autism Diagnostic Observation Schedule (ADOS) is a standardized, play-based assessment designed to observe social and communication behaviors that are often associated with autism. It helps professionals evaluate key behaviors such as eye contact, facial expressions, gestures, language use, play, and social interactions.

You can expect our ADOS-trained technician to show up with a large plastic tote box full of toys, games, and activities! Don't feel overwhelmed; each item is important for the assessment but the technician knows exactly how to administer each one.

The ADOS is used alongside other assessments, such as parent interviews, developmental histories, and questionnaires, to provide a comprehensive understanding of a child's strengths and challenges. Together, these assessments help our clinical psychologists make an informed diagnosis.

The ADOS Process: What to Expect

Here’s what you can expect when your child undergoes an ADOS assessment:

1. Pre-Evaluation Preparation:

Before the ADOS assessment, you may be asked to fill out questionnaires or provide a developmental history of your child. This helps the evaluator understand your child's background, behavior, and developmental milestones.

2. Selecting the Right Module:

The ADOS consists of different modules, each tailored to a specific age group and language level. The evaluator will choose the appropriate module based on your child's age and communication skills, ranging from toddlers to adults. The assessment typically takes 30 to 60 minutes.

3. Play-Based Assessment:

During the ADOS, a trained professional, such as a psychologist or a technician, will engage with your child through structured activities and play-based tasks. These activities are designed to elicit a variety of behaviors, such as communication, social interaction, imaginative play, and response to social cues. For example, the evaluator might play with toys, engage in pretend play, or ask the child to describe pictures or solve simple problems.

4. Observation and Scoring:

The evaluator observes and scores your child’s behavior during the activities, looking for specific behaviors that align with diagnostic criteria for autism. Don't worry, the scoring has nothing to do with how "smart" your kid is, and there's no pass/fail! The scoring is based on the frequency and quality of certain behaviors, such as how often your child initiates social interaction, responds to their name, or uses nonverbal communication like pointing or gesturing.

5. Parent Involvement:

While the ADOS is primarily focused on observing your child, parents may be present in the room or nearby during the assessment. In fact, we encourage it. (The evaluator is not there to babysit!) The evaluator may ask parents questions or seek clarification on specific behaviors observed during the session, but it's important to let the evaluator focus on the assessment so they don't miss anything or cause the session to go too long.

What Parents Should Know Before the ADOS Evaluation

- Prepare Your Child:

If your child is old enough to understand, you can explain to them that they will be playing games and talking with a friendly adult. Emphasize that there are no right or wrong answers; the goal is simply to see how they interact and communicate.

- Be Ready for Honest Observations:

The evaluator will be looking for a range of behaviors, including those that may be challenging for your child. Keep in mind that these observations are essential for a thorough evaluation.

- Ask Questions:

Don’t hesitate to ask the evaluator about the process, what specific behaviors they are looking for, or any other concerns you may have. Understanding the process can help ease any anxiety you might feel. However, it's also good to let the evaluator finish the assessment in a timely manner so your child doesn't get overstimulated or tired too soon.

How Is the ADOS Used to Diagnose Autism?

The ADOS is not a standalone diagnostic tool. Instead, it is used in combination with other assessments, such as developmental histories, parent interviews, and additional standardized tests. The results of the ADOS provide critical insights into a child's social communication skills, play, and behaviors that are often indicative of autism.

The evaluator will analyze the ADOS scores alongside other information gathered to determine if a child meets the diagnostic criteria for autism as outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). If a diagnosis is made by our psychologist, you will be given a detailed report that includes recommendations for services and support, such as ABA therapy, speech therapy, or special education services.

Why Is the ADOS Important?

The ADOS is widely regarded as one of the most reliable tools for diagnosing autism because it provides a standardized method for observing and assessing behaviors in a controlled setting. This helps ensure that the evaluation is objective and consistent, regardless of where or by whom it is conducted.
