What is the ASQ Calculator?

The ASQ Calculator is a tool used to determine which ASQ screening interval (in months) is most appropriate for a child, based on their birth date, current age, and whether they were born prematurely.

Step-by-Step Instructions

1. Enter the Child's Date of Birth

• This is the actual date the child was born.

2. Enter the Screening/Test Date

• Use today’s date or the planned date of screening.

3. Indicate if the Child Was Born Prematurely

• Select "Yes" if the child was born before 37 weeks.
• Select "No" if they were full-term.

4. Enter How Many Weeks Early

• If premature, provide the number of weeks early.
• The tool automatically adjusts the child’s age to account for prematurity.

5. Click “Calculate ASQ Age”

• The results will show:
  • Chronological Age (how many months since birth)
  • Adjusted Age (with prematurity taken into account)
  • Suggested Questionnaire Interval (e.g. 12 months)

Example

Let’s say a child was born on January 1, 2024, and the screening is happening on May 1, 2025.

• The child is 16 months old.
• If born 4 weeks early, the adjusted age is 15 months.
• The calculator recommends the 15- or 16-month questionnaire (nearest available interval).
