Ages and Stages Questionnaire: Social-Emotional (ASQ-SE)

Please note that this tool is proprietary and may only be obtained by contacting the creators of the tool below. However, there is a score summary form available for use in ETO.

The ASQ-SE helps identify "young children at risk for social or emotional difficulties, identify behaviors of concern to caregivers, and identify any need for further assessment." It screens in the areas of "self-regulation, compliance, communication, adaptive behaviors, autonomy, affect, and interaction with people."  The assessment tool is available in 8 versions to allow assessment at: 6, 12, 18, 24, 30, 36, 48, and 60 months of age.  The web-site provides an age calculator to assist in choosing the right tool by factoring in weeks born premature:

The tool can be administered electronically or through paper and pencil, and is written at the 6th grade reading level to make it easier for parents to understand. Completing the questionnaire takes about 10-15 minutes, and involves parents observing the behavior of their children.

The availability of the tool at various age levels allows the developmental progress of the children to be tracked over time.

The tool can be purchased at: Ages and Stages Questionnaire

Scoring / Benchmarking
There are three response options: Most of the time, Sometimes, Never or Rarely. Parents are also provided with a box for each item to allow them to indicate if they have a concern about that behavior.

Trained professional or paraprofessionals convert item responses to point- values, which are then summed within each developmental area. Scores are used to determine if the child is above, close to, or below the cut-off. See manual for specific scoring details.
Background / Quality
High reliability and validity.
