Chronological and Adjusted Age Calculations
ASQ Calculator brings the age calculation workflow into a compact form for routine screening work. Enter the child's date of birth, the questionnaire administration date, and the number of weeks premature when an adjusted age is needed. The result helps place the child in the right developmental-screening time frame without relying on a separate manual calculation.
The Calculate age screen keeps the process visible with date pickers, a weeks-premature selector, and clear Calculate and Clear buttons. Its guidance connects the result to ASQ-3 and ASQ:SE-2 questionnaire intervals, making it useful when a practitioner needs a quick, repeatable check before choosing the next form.
ASQ Questionnaire Interval Guidance
The app is built around the Ages & Stages Questionnaire system rather than a general-purpose date calculator. Its age result indicates the recommended questionnaire interval for ASQ-3 and ASQ:SE-2, helping screening teams match the child's timing to the appropriate form and keep the selection step consistent.
The Help section explains the relationship between chronological age, premature weeks, and questionnaire administration dates in plain language. It also notes that users of the first edition of ASQ:SE can use the age calculation and then consult that edition's administration chart, while the current interval guidance centers on ASQ-3 and ASQ:SE-2. This keeps the selection step clear for staff preparing screening materials.
Adjusted Scores for Missing Items
When questionnaire items are unanswered, Adjust Score provides a focused way to calculate an adjusted ASQ result. Choose the screener, enter the total score and number of missing items, and add the questionnaire interval when using ASQ:SE-2. This keeps the missing-item calculation separate from the age-selection workflow.
The screen presents Screener, Interval, Unanswered Items, and Total Score choices before the Calculate button. The guidance explains that adjusted scores do not penalize unanswered items, while ASQ-3 and ASQ:SE-2 have different limits on how many missing items can be scored. First-edition ASQ:SE adjusted scores require its own user-guide method.
Quick Workflow for Screening Programs
ASQ Calculator suits early-childhood professionals and screening programs that need a quick calculation aid during routine Ages & Stages work. It is useful when a team is selecting an ASQ-3 or ASQ:SE-2 interval, accounting for premature birth, or checking an adjusted score before documenting results in its normal screening process.
The bottom navigation keeps Calculate age, Adjust Score, Help, and About one tap apart, so users can move from a calculation to instructions without leaving the app. The focused two-tool design is especially practical for repeat checks at a desk, in a clinic, or wherever an ASQ questionnaire is being prepared.
