Autism Screening in Children: What to Know About Screening for Autism (ASD)
Autism screening in children is the first step in identifying developmental delays and early signs of Autism Spectrum Disorder (ASD). Early detection plays a critical role in ensuring timely intervention and better developmental outcomes.
Autism is a complex condition/disorder wherein the individual or child shows challenges in the areas of social skills, communication skills and behaviors. The disorder, which falls within Autism Spectrum Disorders (ASD), has a range of symptoms which may vary from child to child.
Why Autism Screening is Important
For parents of young children, knowing when to screen for possibility of Autism is important. However, common questions include:
When should a child be screened for autism?
How is autism screening done?
Who conducts autism screening?
Why is early screening important?
This article addresses these key concerns.
What is Autism Screening?
Autism Screening for Autism gives an impression of whether a child’s development indicates ‘red flags’ (i.e. challenges or skills that can be of concern) and whether the child needs to be seen for further detailed assessments. The screening assessment is different from a diagnostic one.
When Should You Screen a Child for Autism?
A child should be screened for autism if there are persistent delays in communication, behavior, or social interaction compared to peers.
If it is noted that the child is persistently showing difference (including a delay) in behavior/s when compared to his / her typically developing peers, it becomes essential to screen the child as soon as possible.
This will help understand whether the child needs further detailed assessments or not.
Who Should Conduct Autism Screening?
Apart from professionals, parent/s or teacher/s can do the screening.
It is best, if the adult/s that spend most amount of time with the child and know him / her should conduct or are part of the screening. This will give a true picture of the child’s skill , challenges or delays.
How is Autism Screening Conducted?
Typically for screening a set of questions are presented. They are directed to understand whether a child has achieved certain skills or not. These questions are focused towards ‘red flags’ or skills that are warning signs for suspected diagnosis of Autism.
Assessing the ‘red flags’ is essential. To know more about the early signs or red flags, read our article.
Each skill that is assessed as a ‘red flag’, has an approximate (developmental) age that it should be achieved within.
Early Signs of Autism
Skill | Expected Age |
Smiling to others | Before 6 months |
Babbling (/b/, /m/, /p/) | By 6 months |
Using gestures | By 12 months |
First meaningful word | 14–18 months |
Using phrases | By 2 years |
If the child fails on several of these skills – it is crucial to meet a physician for a confirmed diagnosis as early as possible. Reaching out to us (at info@1specialplace.com), will allow you to be guided appropriately.
What Are Autism Red Flags?
Autism red flags include delays in speech, lack of eye contact, reduced social interaction, and repetitive behaviors.
Assessing these red flags is essential in early screening. To know more about early signs, refer to related articles on autism indicators.
Screening Tools for Autism (M-CHAT and More)
There are also checklists such as M-CHAT (Modified – Checklist for Autism in Toddlers) available on the internet that can be easily accessed by parents. They will also help screen a child for the possibility of Autism. Several physicians / therapists would use the same as a screening tool, also. However, kindly note that any checklist has some possibility of being incorrect. Therefore, seeking professional assistance before any confirmation is prudent.
What to Do If Your Child Fails Autism Screening
If your child fails the screening assessment. Seek an appointment and visit the physician as early as possible. Meeting a developmental peadiatrician or a child psychologist would be ideal. They will assess the child in-depth and provide guidance further. An early diagnosis has become possible by a trained eye.
Importance of Early Diagnosis and Intervention
Early diagnosis and early intervention should not be undermined! They are vital. Seek professional help as early as needed. At times, let your instincts guide you. If you think that child has some delays and differences – visit the physician as soon as possible.
