Autism is a developmental disorder that affects communication, social interaction, and behavior. Early detection of autism is crucial for proper diagnosis and intervention. Several tests and tools can help healthcare professionals and educators identify signs of autism in children and adults. In this article, we will present the 10 main tests used to detect autism, highlighting their characteristics and importance in the diagnostic process.
Tests to identify autism: what are the main options currently available?
Currently, there are several tests available to identify autism in children and adults. These tests are essential for an accurate diagnosis and the implementation of appropriate interventions. Below, we list the 10 main tests used to detect autism:
1. Childhood Autism Rating Scale (CARS): This test is used to assess behaviors characteristic of autism in children.
2. Social Communication Questionnaire (SCQ): This questionnaire is used to identify social communication difficulties associated with autism.
3. Autism Diagnostic Interview-Revised (ADI-R): This interview is conducted with parents and/or caregivers to gather information about the child's behavior.
4. Autistic Behavior Assessment Scale (ABC): This test assesses autism-specific behaviors such as communication and social interaction.
5. Childhood Autism Screening Questionnaire (CHAT): This questionnaire is used to identify early signs of autism in young children.
6. Autism Spectrum Assessment Scale (ADOS): This test is administered by specialized professionals to assess the presence of autistic behaviors.
7. Child Behavior Questionnaire (CBCL): This questionnaire is used to identify problematic behaviors associated with autism.
8. Autism Symptom Assessment Scale (ASSQ): This test assesses the presence of autism symptoms in children and adolescents.
9. Behavior Observation Test (TOC): This test involves direct observation of the child's behavior in different contexts.
10. Adult Autism Diagnostic Interview (ADI-R): This interview is conducted with adults to gather information about developmental and behavioral history.
It's important to emphasize that autism diagnosis should be made by qualified and experienced professionals, who use a combination of tests and assessments to obtain an accurate diagnosis. If you suspect you or someone close to you may have autism, it's essential to seek help from a specialized professional to perform the necessary testing and obtain appropriate support.
What type of test is performed to diagnose autism in children?
To diagnose autism in children, several tests and exams are performed to help health professionals identify the characteristic symptoms of the disorder. One of the main tests for diagnosing autism is the ADI-R (Diagnostic Interview for Autism – Revised), which is a structured interview administered to the child's parents or caregivers to assess social behavior, communication, and restricted and repetitive interest patterns.
Besides the ADI-R, another commonly used exam is the ADOS (Observation Scales for the Diagnosis of Autism), which consists of a series of standardized activities carried out by the health professional in order to observe the child's behavior in different social and interaction situations.
Another important test is the evaluation of the QI (Intelligence Quotient) of the child, which can reveal significant differences in relation to the cognitive and communication skills typical of children with autism.
In addition to these tests, neurological, genetic and developmental assessments can also be performed, which aid in the accurate diagnosis of autism in childhood.
Therefore, the combination of different tests and exams is essential to identify autism in children and provide the necessary support for the development and quality of life of these individuals.
Key diagnostic tools for autism: learn about the available options.
To detect autism, there are several diagnostic tools available that can help healthcare professionals accurately and early identify the condition. Understanding the main testing options for autism is crucial to ensuring an accurate diagnosis and initiating treatment as early as possible.
Among the top 10 tests for detecting autism, the following stand out: ADI-R (Diagnostic Interview for Autism-Revised), the ADOS (Autism Observation Scale for Children), the CARS (Childhood Autism Rating Scale), the M-CHAT (Modified Screening Questionnaire for Autism in Young Children) and the SCQ (Social Communication Questionnaire).
In addition to these tests, the following are also used: ADI-R (Diagnostic Interview for Autism-Revised), the ADOS (Autism Observation Scale for Children), the CARS (Childhood Autism Rating Scale), the M-CHAT (Modified Screening Questionnaire for Autism in Young Children) and the SCQ (Social Communication Questionnaire).
These diagnostic tools for autism are essential for identifying the characteristic signs and symptoms of this disorder, enabling appropriate referral for therapeutic and educational interventions. It is important to emphasize that autism diagnosis should be made by specialized professionals, who will assess the clinical picture comprehensively and individually.
Find out which instrument is used to screen for autism in children.
Autism is a developmental disorder that affects children's communication, social interaction, and behavior. Early detection of autism is essential to ensure appropriate treatment and improve the child's quality of life. Several tests are available to aid in the diagnosis of autism, one of the most widely used being the M-CHAT, a questionnaire completed by the child's parents or caregivers.
The M-CHAT, which stands for Modified Checklist for Autism in Toddlers, is a screening tool for autism in children aged 16 to 30 months. The test consists of 23 questions that assess the child's behavior in various areas, such as social interaction, communication, and behavioral patterns. The answers help identify possible signs of autism, indicating the need for further evaluation by a healthcare professional.
In addition to the M-CHAT, there are other important tests for detecting autism, such as the ADOS-2 (Autism Diagnostic Observation Schedule), the CARS (Childhood Autism Rating Scale), and the SCQ (Social Communication Questionnaire). Each of these instruments has its own characteristics and objectives, contributing to a more complete and accurate assessment of the disorder.
It's important to be aware of the signs of autism and seek professional help if you suspect the disorder. The earlier autism is detected, the better the chances of intervention and improving the child's quality of life.
Top 10 Tests for Detecting Autism
When we think of any type of childhood developmental disorder, the first names that probably come to mind are ADHD and autism. The latter condition is particularly difficult for many people to understand and can cause significant distress for the child who suffers from it, feeling misunderstood and unappreciated by those around them, and fearing they can't be reached.
Having autism also involves a series of difficulties that must be faced and treated throughout the individual's development and life. But to help this segment of the population, it is first necessary to determine whether or not they have this disorder. In this sense, we need a series of tests to detect autism In this article, we will mention some of the most applicable ones.
Autism: what is it?
Before going into some of the main tests and tests available to detect autism, it would be helpful to delve a little deeper into our understanding of this disorder.
We call autism, now autism spectrum disorder, a type of neurodevelopmental disorder (i.e., it originates during the growth and neurodevelopmental stage) characterized by the presence of problems and severe difficulties in language, socialization, and behavior. This disorder usually can be detected before the age of three , appearing at very early stages of life.
Each of the three aspects mentioned above presents particularities difficult for the child to adapt to the environment .
At the socio-relational level, we observe a lack of interaction and apparent disinterest in relationships with others, resulting in a self-isolation. People with this disorder have serious difficulties developing a theory of mind that allows them to see others as entities with independent minds, separate from their own. There is difficulty initiating and responding to social interactions, and there is little socio-emotional reciprocity.
Regarding communication problems , a marked literalness is observed (they often don't understand figurative language), as well as significant difficulty or inability to understand and use nonverbal language. Delays in language acquisition are also not uncommon, and difficulties with practical use appropriate to context are notorious. In some cases, the individual may not develop language at all. They also tend to have problems with speech changes and responding to interactions.
Finally, they also present changes in behavior. He highlights the presence of restricted interests and a great need for routines , with the presence of changes being extremely stressful for them, as they need a sense of security. It's not uncommon for them to exhibit repetitive expressions, movements, or use of objects, usually as a way to calm themselves. It's also been observed that there's often hyper- or hyposensitivity to stimulation, overreacting or not reacting at all to noises and lights.
These are some of the main characteristics and criteria of people with autism. It should also be taken into account that, although it is usually diagnosed in children, it is a chronic disorder that persists into adulthood and requires adequate therapeutic treatment to reduce possible involvement in various areas of life and increase the level of autonomy and well-being of these people.

The main autism screening tests
A key aspect of being able to intervene in this disorder is detecting it. To this end, several tests have been developed over the years to detect the presence of an autism spectrum disorder and the aspects that are altered in each case. These tests can be administered to various agents, whether to the child themselves or, more generally, to parents and teachers.
Below, we will look at some of the best-known tests that are commonly used in detecting autism, recommended by well-known publishers such as TEA Editions or different organizations specializing in Autism.
It's important to keep in mind that the ones we'll mention aren't all there are, but just some of the most representative. It should also be noted that, in this as in other disorders, the results of one test are not decisive or sufficient for diagnosis; other information, such as those obtained in an interview, through observation of the person or with the patient. Reports from other people .
1. Autism Diagnostic Observation Scale (ADOS)
One of the best-known benchmark tests for diagnosing autism, it is a scale developed to assess communication skills, social interaction, play, and the use of materials, and to provide cutoff points. It consists of four modules, only what is appropriate to the subject in question is applied by age group and communicative level . A minimum mental age of two years is required and allows the child to be assessed based on their performance. More advanced versions are now available, such as the ADOS 2, which assesses both children and adults.
2. Autism Diagnostic Interview (ADI)
The ADI and its review (ADI-R) are clinical interviews designed to provide a comprehensive assessment of a possible case of autism. It consists of about 93 questions (in the ADI-R version) that explore language, reciprocal social interaction, and restricted behaviors/interests. It focuses on typical behaviors of individuals with autism that rarely appear in people without this condition. The scores can be coded and subsequently interpreted algorithmically, without comparative scales.
3. Adaptive Behavior Assessment System (ABAS)
Instrument that assesses adaptive behavior from birth to 89 years of age. It assesses the areas of communication, use of community resources, functional academic skills, home life, school life, health and safety, leisure, self-care, self-direction, social, motor, and employment.
The second version (ABAS-II) also includes the global conceptual, social, and practical indices. Although it's not limited to autism, it allows for the assessment of the main areas affected by this disorder. Parents, teachers, or relatives usually answer and complete the test, although the individual may also complete it.
4. Autism Spectrum Quotient (AQ)
This is a 50-question Baron-Cohen questionnaire, which must be completed by the individual, and is based on the degree of agreement (between complete agreement and complete disagreement, there are a total of four possible answers) with each of the different questions. In this sense, we can find specific versions for different profiles, such as the Autism Spectrum Quotient for Children (AQC), Autism Spectrum Quotient for Adolescents (AQA), and Abbreviated Autism Spectrum Quotient (AQS).
They can also be completed by relatives or teachers. It offers cutoff points that allow us to separate the old Kanner type of autism from Asperger syndrome and allows different phenotypes to be distinguished.
5. Social Communication Questionnaire (SCQ)
This short questionnaire, to be completed by the subject's caregivers, consists of a total of 40 items, including interaction problems, communication problems, and restricted and stereotyped behaviors. It has a form A that assesses the subject's entire life and a form B that assesses the situation over the past three months. Depending on the result, another more comprehensive test, such as the ADOS or ADI, may be recommended.
6. Autism Spectrum Screening Questionnaire (ASSQ)
This questionnaire is intended for children between seven and sixteen years old and consists of a total of 27 questions to answer with Yes/No/Sometimes. It is more of a screening tool and tends to focus more on the former Asperger's (now part of the autism spectrum disorder). Must be completed by parents and teachers and allows the identification of different predominant characteristics in children with social interaction and behavior problems. Currently, there is a revised version (ASSQ-REV), which is more complete.
7. Modified Childhood Autism Questionnaire (M-CHAT)
Screening test to be completed by the child's parents. If this fails on more than three items, a more detailed exploration should be undertaken. to assess the presence of ASD. Designed to assess children under two years of age, based on yes or no questions.
8. Autism Spectrum Inventory (ASI)
An inventory designed to assess a dozen characteristics of people with autism and other neurodevelopmental disorders. More than just detection, it focuses on assessing the severity of the patient's condition. Allows you to identify the severity of autistic traits , in addition to generating treatment guidelines and testing the changes that these treatments generate.
Furthermore, depending on the score, the individual can be classified into four different types of autism (highlighting classic and Asperger's, as well as regressive autism and high-functioning autism). It must be completed by the professional based on information from observation and interviews with the environment.
9. Infant and Toddler Questionnaire (CSBS DP)
It's a scale that assesses the presence of different predictors of language and social communication. It's designed for ages six months to two years. It should be completed by the child's parents, caregiver, or someone in frequent contact with the child.
10. Childhood Asperger Syndrome Test (CAST)
37-question questionnaire that allows early detection of characteristics of children with Asperger's . It is passed on by parents of children between four and eleven years of age.
