How Do Clinicians Assess Nonverbal Communication in Autism Evaluations? 

Author: Hannah Smith, MSc | Reviewed by: Dr. Rebecca Fernandez, MBBS

Nonverbal communication in autism evaluation plays a key role in diagnosing autism spectrum disorder (ASD). Since many individuals with autism may struggle with nonverbal cues like eye contact, gestures, and facial expressions, assessing these behaviours is essential during the evaluation process. Clinicians observe how a child uses and responds to nonverbal communication to identify potential signs of autism, guiding their diagnostic decisions. 

In autism evaluations, professionals use various assessment tools to evaluate nonverbal communication. These tools focus on a child’s ability to engage in social interactions, including their use of gestures, eye gaze, and facial expressions. 

How Clinicians Use Assessment Tools to Evaluate Nonverbal Communication in Autism 

These are some observation methods and tools clinicians use to assess nonverbal communication in autism evaluations. 

Observation of Gestures and Eye Contact  

One of the primary ways clinicians assess nonverbal communication in autism evaluation is by observing how children use gestures like pointing or waving and whether they maintain eye contact during social interactions. Assessment tools, such as the Autism Diagnostic Observation Schedule (ADOS), are used to observe and score these behaviours during structured play or interaction. 

Evaluating Facial Expressions  

Another critical aspect of nonverbal communication in autism evaluation is assessing how children express emotions through facial expressions. Limited or atypical facial expressions can be a key indicator of autism.  

Social Interaction and Engagement  

During an autism evaluation, clinicians also assess how children engage socially, using their nonverbal cues to initiate or respond to social interactions. Evaluation tools like the Childhood Autism Rating Scale (CARS) help clinicians score these behaviours to gauge social communication skills.
