Preventive health service in which a child's age-appropriate motor, language, social, and cognitive skills are systematically evaluated using standardized tools such as Denver II and Bayley.
Indication
- Suspicion of speech delay, limited vocabulary, or inability to form sentences
- Delay in walking, sitting, or fine motor skills relative to age
- Difficulty with eye contact and social interaction or repetitive behaviors
- Behavioral or learning difficulties noticed by family, daycare, or school
- History of premature birth, low birth weight, or neonatal intensive care
- Diagnosis of a genetic syndrome, chromosomal anomaly, or congenital brain or muscle disease
- Age-appropriate screening as part of routine well-child visits
Preparation
- Schedule the appointment when the child is not hungry, sleep-deprived, or ill
- Bring the vaccination card, hospital birth records, and previous test results
- Family history; mention any speech delay, learning difficulties, or neurological diseases
- Take notes about the child's daily routine, toy preferences, and communication style
- Bring feedback and observation reports from daycare or school
How it's performed
- The physician or developmental specialist takes a detailed birth and developmental history
- Age-appropriate standardized screening tests (e.g., Denver II, ASQ-3, M-CHAT, Bayley III) are administered
- The child is observed; in a play setting, motor skills, language, attention, and social interaction are evaluated
- If hearing or vision concerns are suspected, further testing (audiometry, ophthalmology examination) is planned
- Nutrition, sleep, screen exposure, and home environment are reviewed
- Results are discussed with the family; an intervention plan is developed if needed
Post-procedure
- If screening is normal, routine well-child follow-up continues; rescreening can occur at the next age interval
- Borderline or suspicious results are reassessed at defined intervals
- If delay is identified in a specific area, speech therapy, physical therapy, occupational therapy, or special education may be planned
- Referral to pediatric neurology, child psychiatry, or genetics is made when needed
- Recommendations on daily play, communication, and enriched stimulation are provided to the family
Risks
- Developmental assessment is non-invasive; it carries no direct medical risk
- Lack of cooperation in a single session may affect reliability; reassessment is planned if needed
- Screening tests do not provide a diagnosis; they only indicate the need for further evaluation
- False-positive results may cause temporary anxiety in the family; comprehensive assessment clarifies this
- Missing the opportunity for early intervention may lead to outcomes that are difficult to reverse in developmental areas
FAQ
The screening result is suspicious — is my child sick?
No. Screening tests do not provide a diagnosis; they only indicate the need for further evaluation. Most suspicious results turn out to be normal on comprehensive assessment, or reach age-appropriate level with support.
Why is early intervention so important?
Brain development is fastest in the first years. In children with identified delay, early-initiated therapy and educational programs significantly improve skill acquisition and long-term quality of life.
At what ages should developmental assessment be performed?
In routine well-child follow-up, 9, 18, 24-30 months, and the preschool period are priority checkpoints. If concerns exist, assessment can be requested at any age.
Does screen use affect development?
Excessive and early passive screen exposure may negatively affect language and social skill development. Age-appropriate limits and interactive play are recommended for healthy development.
