Social-emotional health: look to ASQ:SE-2 for truly accurate screening.

Early identification of social-emotional challenges can make all the difference to a young child. The proof is undeniable: the earlier a behavioral concern is identified, the greater the chance a child has for reaching his or her full potential in life. This is the driving force behind Ages & Stages Questionnaires®: Social-Emotional, Second Edition (ASQ®:SE-2)—a parent-completed, highly reliable system focused solely on social-emotional development in young children. Accurately identifying behavior through ASQ:SE-2 paves the way for next steps—further assessment, specialized intervention or ongoing monitoring, for examples—to help children reach their fullest potential during their most formative early years.



Product Overview

ASQ:SE-2: The big picture.

With the typical ups and downs of young children’s emotions and behavior, delays or problems can be easily missed. And today, as more children are increasingly exposed to risk factors such as poverty or toxic stress, the likelihood of depression, anxiety, and anti-social behavior increases. There is tremendous opportunity during the first few years of a child’s life to identify and address potential social-emotional concerns. This is at the heart of ASQ®:SE-2. It is modeled after the acclaimed ASQ®-3 and is tailored to identify and exclusively screen social and emotional behaviors. ASQ:SE-2 is an easy-to-use tool with all the advantages of ASQ-3—it’s cost-effective, parent-completed, photocopiable, and culturally sensitive. With questionnaire results, professionals can quickly recognize young children at risk for social or emotional difficulties, identify behaviors of concern to caregivers, and identify any need for further assessment.

Can ASQ:SE-2 Be Used as a Developmental Screener?

ASQ:SE-2 focuses on social-emotional skills and behavior. To be sure that you are taking a comprehensive look at a young child’s development, use ASQ:SE-2 in conjunction with ASQ-3 or another developmental screening measure that provides information on a child’s general functioning in communication, motor, and cognitive areas.

Technical Info

ASQ:SE-2: A technical snapshot.

Validity, reliability, and utility studies were conducted on ASQ:SE-2 between 2009 and 2011 to accurately determine the psychometric properties of the screening instrument. Normative studies included 14,074 children, ages 1 month up to 72 months. The results support the ability of ASQ:SE-2 to discriminate between children with social-emotional delays and those who appear to be developing typically in social-emotional areas.

  • Internal consistency, measured by Cronbach’s coefficient alpha, ranged from 71%–91%, indicating strong relationships between questionnaire total scores and individual items.
  • Test-retest reliability, measured as the agreement between two ASQ:SE questionnaires completed by parents at 1- to 3-week intervals, was 89%. These results suggest that ASQ:SE scores were stable across time intervals.
  • Concurrent validity, as reported in percentage agreement between ASQ:SE and concurrent measures, ranged from 71% to 90%, with an overall agreement of 84%.
  • Sensitivity, or the ability of the screening tool to identify those children with social-emotional disabilities, 78% at 2 months to 84% at 24 months, with 81% overall sensitivity.
  • Specificity, or the ability of the screening tool to correctly identify those children without social-emotional delays, ranged from 76% at 18 months to 98% at 60 months with 83% overall specificity.
