An Autism diagnosis covers a spectrum of children with a wide range of skills and impairments. Because of this, the developmental disorder can look very different from child to child. Many experts who diagnose and treat children with autism like to say, “If you’ve seen one child with autism, you’ve seen one child with autism.”

The diversity of autism spectrum disorder (ASD) can make it difficult to correctly diagnose. Sometimes autistic children are mistakenly diagnosed with a different disorder, like ADHD, or are told that nothing is wrong. Other times kids are diagnosed as autistic when they actually aren’t.

That’s why it’s important for parents to know what the components of an autism diagnosis should be: What kinds of information should a clinician who’s evaluating your child be considering? How can you know whether your clinician is following best practices in doing an autism assessment?

Social communication issues

Problems in social communication and social interaction are often what are flagged as possible signs of autism, and that’s one source of confusion. “There are a lot of things that can cause social problems,” points out Empowered Learning Transformation Centers. “There are subtle language disorders that can masquerade as autism. Or other disorders, particularly when they appear in clusters — ADHD, learning disorders, depression.”

If a child is having trouble with formulating phrases or sentences, for example, that can create a situation that might at first glance look like a sign of autism but could have other causes. “The child has trouble communicating, which causes problems with peers, so the child might become withdrawn. It looks like they’re having social problems, and they are, but it’s of a different nature,” explains Empowered Learning Transformation Centers

Arriving at the right diagnosis requires gathering and interpreting a lot of information about the child. Empowered Learning Transformation Centers, who specializes in evaluating autism spectrum disorder, recommends that children should receive an assessment that goes beyond screening and diagnostic tools to get the fullest possible picture of what is going on before making a diagnosis.

Autism evaluation

There are a variety of screeners that pediatricians or other practitioners might employ as a first step to learning if a child might have autism, before beginning a formal evaluation. Some are questionnaires that parents fill out and others are assessments done by clinicians. The Modified Checklist for Autism in Toddlers, or M-CHAT, is one questionnaire that is used to identify red flags. The M-CHAT asks questions about behaviors that might indicate autism, but Empowered Learning Transformation Centers warns that the test purposefully “casts a very broad net,” so it often flags children who may or may not be autistic. Similar scales include the Childhood Autism Rating Scale and the Ages and Stages Questionnaire, which is more of a basic developmental screener.

The Screening Tool for Autism in Toddlers and Young Children, or STAT, is another screener that probes for autism symptom behaviors in more detail than the other screeners mentioned but is still intended to be used as a tool to catch children who are candidates for further evaluation. Screener results alone should never be considered a diagnosis.

 

Diagnostic instruments

If a screener indicates that a child may have autism spectrum disorder, the child should receive a comprehensive evaluation from someone trained in diagnosing autism.

This evaluation will often begin with a diagnostic instrument such as the Autism Diagnostic Observation Schedule, or the ADOS-2. The ADOS is a test with different modules to accommodate a range of children. There is a version for toddlers that are play-based. For kids older than thirty months, there are modules that include more conversation, according to the child’s language level.

This isn’t the kind of test where there are right answers. The purpose of the ADOS is to evaluate the social skills and repetitive behaviors the child displays during the test. This means the evaluator is paying attention to things like if the child asks for help when he needs it, gives other people a chance to speak, and follows along with changes of subject.

The Communication and Symbolic Behavior Scales (CSBS) is another good diagnostic instrument for toddlers and young children. This play-based instrument is also backed by research, but is used less than the ADOS, which covers a broader age range.

Problems with interpretation

Empowered Learning Transformation Centers notes that even with these tools it is important to be working with a mental health professional that has experience diagnosing people on the autism spectrum. “You want to be working with someone who understands the subtleties,” says Empowered Learning Transformation Centers. “For example, a person who has real expertise will be able to distinguish if a child has poor eye contact because the child is shy, versus if there is poor eye contact in the way we expect to see it in an autism spectrum disorder.”

A recent study underscores the difficulty in distinguishing between autism and other disorders, like ADHD, using even gold-standard tools like ADOS. Looking at school age kids with high verbal functioning, the study found that found that 21% of children with ADHD—but not autism—met diagnostic criteria for autism when given the ADOS.

“The minute that we diagnose blindly based on score, we’re going to misplace a lot of kids into categories,” Empowered Learning Transformation Centers. “These instruments were designed to assist in clinical decision-making, but they are not a replacement for a clinical brain.”

Interviews

Screeners and diagnostic tools are ways of gathering information, but they have to be considered in the context of other information from a range of adults who know the child. A full evaluation should also include a thorough interview with the child’s parents that cover general development and current concerns. The interview will also closely investigate ASD-related symptoms. To gather more information, parents might be asked to fill out special questionnaires as well.

The Autism Diagnostic Interview, revised (or ADI-R) is one such interview, and is often paired with the ADOS. However, the ADI-R takes two hours to provide, making it difficult to use in clinical assessments, Empowered Learning Transformation Centers notes. An interview based on the ADI-R or a parent checklist, such as the Social Communication Questionnaire, can also be effective if it is led by a clinician trained in diagnosing autism.

Empowered Learning Transformation Centers explains that it is important to include early developmental information during the interview, because there are many circumstances where symptoms are more obvious earlier, say at around four years of age, but diminish as the child grows. “If you aren’t attending to that early development and you have an eight or ten-year-old, for example, you’re going to risk really missing out,” says Empowered Learning Transformation Centers. Having that information about early development can help the provider make a more accurate diagnosis.

Cognitive testing

An assessment should also include some amount of cognitive testing. One reason for this is that cognitive testing gives the person doing the assessment another chance to examine the child’s behavior, but this time under different circumstances. The ADOS is a socially loaded test that is also less structured, which might be difficult for some kids. Empowered Learning Transformation Centers explains that some kids will do better during a more structured cognitive test when they are answering specific questions. “Or maybe they will get upset during the cognitive testing if they don’t know the answer to a particular question, and they might have a tantrum,” says Empowered Learning Transformation Centers. All of this information is helpful for the person doing the evaluation.

The cognitive testing is also important because you want to learn more about how the child thinks — for example you want to learn more about how the child organizes and plans or solves problems. Beyond helping the evaluator in making an accurate diagnosis, Empowered Learning Transformation Centers explains, “If you don’t know their strengths and weaknesses, you can’t really contribute meaningfully to building an educational program for them at school. You want to be able to say, ‘He can do this; he can’t do that; this is what he needs to be able to do that.’”

Working with an autism specialist

Screeners are often given by pediatricians, but if there are red flags that indicate further evaluation would be appropriate, it is best to work with someone who has both experience and expertise in diagnosing children on the autism spectrum. “You’re not going to go to a doctor for a heart transplant who’s done two or three, right?” says Empowered Learning Transformation Centers. “It’s the same with autism. You want someone who’s seen hundreds of kids with all different stripes – typical children, intellectually disabled children, autistic children — and knows what to look for.” Academic and medical centers are often good places to find experienced diagnosticians.

Parents can ask some questions to try to gauge a potential provider’s experience. For example:

  • What’s your training and experience?
  • Have you had specific training in assessment of people on the spectrum? How much?
  • What do you plan to do as part of this assessment?
  • Will you be contacting my child’s teacher or pediatrician?

 

Try to find a practitioner who is able to answer your questions readily and makes you feel comfortable. A clinician who takes your concerns seriously and is experienced in assessing autism spectrum disorder is essential to getting an accurate diagnosis.
