About the Measure

Domains Social Emotional
Subscales No
Target Construct Social emotional: Communication skills and social functioning
Description Previously known as the Autism Screening Questionnaire (ASQ), the SCQ is a brief instrument that helps to evaluate the communication skills and social functioning of an individual who may have autism or other autism spectrum disorders. The SCQ is suitable for screening and monitoring. It is not suitable for diagnosis because it does not give information relating to onset, course and pervasiveness of symptoms across contexts. Moreover it is based on caregiver reports and, for diagnostic purposes, these need to be checked against direct clinical observation.

UK norms YES
Norm / Criterion referenced Norm referenced
Standardisation sample 200
Reliability Insufficient data in the public domain to evaluate
Criterion validity Insufficient data in the public domain to evaluate
Construct validity Lower internal consistencies, a weaker factor structure, lower item discriminations, significant pseudo-guessing effects, and subscale-level measurement bias. Caution researchers and clinicians about the use of the SCQ Current form. In particular, it seems inappropriate to use the Current form as an alternative to the Lifetime form among children younger than 5 years old or under other special situations (e.g., teacher-report data).Wei, Chesnut, Barnard-Brak & Richman (2015)
Concurrent validity The inter-correlations found between the ADI-R and the SCQ were reported s: for the reciprocal social interaction domain r= .92, for the communication domain r= .73, and for the restricted, repetitive and stereotyped patterns of behaviour domain r=.89, indicating a high level of validity for the SCQ.
