Frequently Asked Questions (FAQ)
What is the ASQ screening age?
The ASQ uses specific questionnaires tailored for ages 1 month to 5.5 years. Finding the exact age in months and days determines which questionnaire to administer.
How does prematurity affect the screening?
If a child is born three or more weeks premature, and is under 24 months old, their age must be adjusted to ensure developmental screening aligns with biological rather than chronological benchmarks.
When should I stop adjusting for prematurity?
Clinical guidelines recommend stopping age adjustments for prematurity once the child reaches 24 months of chronological age.
What is a month in ASQ calculations?
A month is mathematically standardized as 30.4375 days (365 days / 12 months).
Is my child's birth date kept secure?
