Recognizing the signs of autism can be challenging at times, including for parents who are unsure of what symptoms to look for. There is no medical test for autism spectrum disorder (ASD), so medical professionals use multiple psychological and cognitive screening tools to closely examine developmental history and behavior to help them make a diagnosis. Below, explore what you might learn from an autism test for yourself or a loved one.

What is autism spectrum disorder?

Autism spectrum disorder (ASD) is a developmental condition and form of neurodiversity that involves challenges with communication and behavior. Parents and caregivers may notice signs of ASD in children before their first birthday, and they tend to be more evident by the time the child reaches two or three. In some cases, symptoms may not be noticeable until the child starts school, as their challenges become more apparent in a group of other children. Autism is lifelong and does not have a cure, so adults with autism continue to be Autistic throughout their lifetime.

What is an autism spectrum test?

Multiple screening tools can help providers identify children and adults who may be on the autism spectrum. A positive autism test is not an autism diagnosis; it is a sign to be screened by a mental health professional for a formal diagnosis. Formal diagnostic tools for autism also include assessments, including those on sensory needs, imagination, and other areas of mental health.

Below are some of the most commonly used autism screening tests

Modified Checklist for Autism in Toddlers (M-CHAT)

The M-CHAT was made for children aged 16 to 30 months. It’s a free questionnaire that asks parents a series of 20 questions about their children’s behavior. Two questions include, “If you point at something across the room, does your child look at it?” and “Does your child make unusual finger movements near [their] eyes?”

Social Attention and Communication Surveillance, Revised (SACS-R) and SACS-Preschool (SACS-PR)

The SACS-R and SACS-PR are for children aged between 12 and 60 months. They are designed to be administered by a trained professional, such as an early childhood educator, psychologist, or other health professional. These tests look at how children communicate and interact with their surroundings.  

Social Challenges Screening Questionnaire (SCSQ)

School-aged children are screened using the SCSQ. This test was designed for medical professionals, parents, and educators and can identify children who have level 1 ASD, previously referred to as Asperger syndrome (an outdated term). Questions on this screening tool include, “Does your child have trouble making or keeping friends?” and “Does your child have difficulty following instructions or the flow of simple conversations?”

The Autism Spectrum Quotient

The Autism Spectrum Quotient Test is a self-administered questionnaire that measures Autistic traits in people over age 16 with an IQ over 80. The test has 30 statements, and the person taking the test chooses how well each statement applies to them, from “definitely agree” to “definitely disagree.” Some statements include, “I prefer to do things on my own rather than with others” and “I find numbers, dates, and strings of information fascinating.”

Screening tools for adults

Some screening tools are designed for adults, including but not limited to the following:

Diagnosis

While screening tests can help providers identify people who could benefit from further screening, specific diagnostic criteria are required for an ASD diagnosis. Below, take a closer look at the diagnostic criteria for ASD listed in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition Revision (DSM-5-TR).

DSM criteria for an autism spectrum disorder diagnosis

To meet the DSM criteria for ASD, a child, teen, or adult must have persistent deficits in each of the three areas: 

  • Social-emotional reciprocity: Deficits in social-emotional reciprocity, including abnormal speech, failure to engage in normal back-and-forth conversation, and failure to respond to or initiate social interactions
  • Communication: Deficits in nonverbal communication in social interactions, including abnormalities in eye contact, poor verbal and non-verbal communication, and lack of eye contact
  • Relationships: Deficits in maintaining, developing, and understanding relationships, including difficulties making friends, adjusting behavior to suit different social situations, and a lack of interest in peers

The severity of symptoms is based on restricted, repetitive patterns of behavior and social communication impairments and is rated from level 1 (requires support) to level 3 (requires very substantial support). For an autism diagnosis, someone must also have at least two of the following types of restricted and repetitive behaviors, activities, or interests listed below: 

  • Repetitive motor movements, speech, or use of objects
  • Inflexibility of routines, insistence on sameness, or ritualized patterns
  • Highly fixated and very strong interests of abnormal focus or intensity
  • Unusual interest in sensory aspects of the environment or hyper- or hypoactivity to sensory input

Symptoms must also be present early in the developmental period and cause significant impairment in occupational, social, and other areas of functioning. These symptoms must also not be better explained by another neurodevelopmental disorder or intellectual disability, such as attention-deficit hyperactivity disorder (ADHD). Note that adults can be diagnosed as Autistic later in life if symptoms were present in their childhood. When meeting with a provider, they may provide a family history or have a family member help them discuss their behaviors throughout life to aid in diagnosis. 

Importance of early identification and self-awareness

Early identification of ASD may benefit children because early intervention programs can improve functional outcomes and quality of life. However, early diagnosis can be challenging because symptoms may be difficult to pick up on before the child starts school, and symptoms can differ from one child to the next. Some parents or caregivers may also have a poor understanding of the early symptoms of ASD. 

Some pediatricians may complete autism screening tests for all patients at well visits. However, if you have concerns about ASD or other developmental disorders, talk to your child's healthcare provider about early screening. If you’re an adult seeking an autism assessment for yourself, look for a provider with experience in diagnosing adults. 

Health implications

ASD can also be associated with several physical and mental health conditions. Symptoms of these conditions may be what initially raise concerns about ASD in some cases.

Physical health

Children and adults with ASD may experience some of the following physical health challenges:

  • Gastrointestinal problems, including constipation, reflux, and abdominal pain
  • Feeding issues, including overeating and pica
  • Epilepsy, which has symptoms like unexplained staring spells, involuntary movements, sleepiness, or severe headaches
  • Sleep problems

Mental health

Symptoms of ASD can overlap with other mental health conditions, but ASD is also commonly comorbid with several other mental health conditions, including the following:

  • ADHD
  • Anxiety, especially social anxiety disorder 
  • Depression
  • Bipolar disorder
  • OCD
  • Schizophrenia
  • Down syndrome

Treatment

Treatment for ASD varies depending on symptoms and is often aimed at reducing symptoms that interfere with quality of life and daily functioning. Multiple approaches to treatment are available, and a combination of more than one approach is often recommended. Autistic children, adolescents, and adults may benefit from behavioral approaches. However, if you’re seeking treatment options, consider researching all modalities and resources before starting, gaining multiple perspectives to understand which modalities are considered most effective and ethical.  

Some providers may recommend developmental approaches to treating ASD to help children or adults develop specific developmental skills. For example, speech and language therapy may help people with ASD improve communication, speech, and language. Occupational therapy may also help people with ASD learn skills to increase independence, like eating, dressing, and bathing. Physical therapy can help improve gross and fine motor skills. Treatment can also include teaching social-relationship skills, such as increasing interests and motivation and learning and practicing social skills.

Getting support

Psychotherapy can also be an effective treatment for people with ASD, particularly cognitive-behavioral therapy (CBT). In CBT, a therapist works with the person with ASH to identify and change the thoughts that lead to problematic behaviors and feelings. This type of therapy can be effective at helping people with ASD manage feelings of anxiety and depression and learn to recognize their emotions and cope with social situations. In addition to supporting people with ASD learn to manage their symptoms, therapy can also be beneficial for parents, caregivers, or family members of people with this condition. 

Some symptoms of autism can make in-person treatment challenging for people with ASD or their loved ones. In these cases, online therapy can be a flexible, convenient option to traditional therapy. With an online therapy platform like BetterHelp, you don’t have to worry about commuting to an office or sitting in a waiting room. You can attend sessions via video chat or phone from your own home or anywhere you have a reliable internet connection. Research has found that online treatment for ASD is also effective. For example, one study found that “Web-based interventions can effectively reduce symptoms in children and young people with neurodevelopmental disorders.”

Takeaway

An autism spectrum test cannot give a definitive diagnosis, but a positive screening can indicate that more evaluation is needed. If you are experiencing symptoms of ASD or if you are the parent of a child with ASD, therapy can help you learn more about managing this condition. Consider contacting a therapist online or in your area to get started.
