ASQ: Ages and Stages Questionnaires

The Ages and Stages Questionnaires (ASQ) is a developmental screening tool designed to assess the developmental progress of children from birth to 5 years of age.

The ASQ is a parent-reported questionnaire that assesses various domains of child development, including communication, fine and gross motor skills, problem-solving, personal-social skills, and adaptive behaviors. It is used to identify potential developmental delays or concerns and determine the need for further evaluation or intervention.

Limitations of the ASQ include the reliance on parent-reported information, which may be subject to biases or inaccuracies.

Scoring and Interpretation:
The ASQ uses a scoring system based on the number and nature of items that the child has achieved. Each item is scored as "yes," "sometimes," or "not yet." The scores are used to identify potential developmental concerns or delays. There are established cutoff scores for each age-specific questionnaire that help determine if further evaluation or intervention is needed.

The ASQ was developed by Jane Squires and Diane Bricker in the 1990s.
