ASQ-3 can be used with children as young as 1 month of age. What is your recommendation for screening newborn infants up to 1 month of age?
If you need to screen newborn infants, you can use the 2 month questionnaire. However, the ASQ developers do not recommend that you refer on the basis of score (i.e., if the child falls below the cutoff). You should wait until the child is 2 months of age and ask parents to complete the 2 month questionnaire again.
