The Ages & Stages Questionnaire: Social-Emotional, Second Edition (ASQ: SE-2) assesses developmental progress in children between the ages of one month to six years. ASQ: SE-2 addresses social competencies and problem behaviors. It is also based on observation and personal interpretation of children’s behavior. ASQ: SE-2 screens seven areas of social-emotional development: self-regulation, compliance, social communication, adaptive functioning, autonomy, affect, and interaction with people. Questionnaires can be completed by parents or teachers, but the tool was developed and validated as a parent-completed tool. Teachers who complete the questionnaire must meet guidelines to ensure they are sufficiently familiar with the child’s skills.
ASQ: SE-2 has excellent internal consistency, test-retest reliability, concurrent validity, sensitivity, and specificity. Children who are screened and receive intervention show significant improvements in their ASQ: SE-2 scores.
