Social Communication Questionnaire (SCQ)
SCQ is a parental questionnaire with 40 yes-or-no items. Two forms of the questionnaire are used: current and lifetime. The questionnaire takes less than 10 minutes, and scoring involves a total score with cutoff points. The SCQ is designed for individuals over 4 years of age, with a mental age over 2 years.
SCQ is a quick and inexpensive way to routinely screen for Autism Spectrum Disorder (ASD).
