A meta-analysis of the social communication questionnaire: Screening for autism spectrum disorder.
Lifetime SCQ works best after age four; Current form and toddler screens lose too much accuracy.
01Research in Context
What this study did
The team pooled every SCQ study they could find. They checked how well the Lifetime form and the Current form spot autism.
They looked at age, sample type, and scoring rules. The goal was one clear accuracy number across all papers.
What they found
The Lifetime SCQ works well overall. Accuracy drops hard if you use the Current form or screen kids under four.
Convenience samples also drag the numbers down. Stick to Lifetime forms with kids over four for best results.
How this fits with other research
Derks et al. (2017) extends the SCQ story to adults with ID. Their short 24-item version keeps good sensitivity but still flags too many false positives.
Che Daud et al. (2026) backs the big picture: tool choice swings prevalence counts. SCQ remains a top pick worldwide, yet cultural checks are still missing.
Warren et al. (2012) sounds a warning that fits today’s data. Parent-report alone can misclassify kids with complex profiles, so clinical follow-up is still required.
Why it matters
Use the Lifetime SCQ, skip the Current form, and wait until age four. Add a second tool or clinical eye when samples feel convenient or when adults with ID are involved. These small choices keep your screening sharp and save hours of false-alarm assessments.

03Original abstract
The current meta-analysis examines the previous research on the utility of the Social Communication Questionnaire as a screening instrument for autism spectrum disorder. Previously published reports have highlighted the inconsistencies between Social Communication Questionnaire-screening results and formal autism spectrum disorder diagnoses. The variations in accuracy resulted in some researchers questioning the validity of the Social Communication Questionnaire. This study systematically examined the accuracy of the Social Communication Questionnaire as a function of the methodological decisions made by researchers screening for autism spectrum disorder over the last 15 years. Findings from this study suggest that the Social Communication Questionnaire is an acceptable screening instrument for autism spectrum disorder (area under the curve = 0.885). Variations in methodological decisions, however, greatly influenced the accuracy of the Social Communication Questionnaire in screening for autism spectrum disorder. Of these methodological variations, using the Current instead of the Lifetime version of the Social Communication Questionnaire resulted in the largest detrimental effect ( d = -3.898), followed by using the Social Communication Questionnaire with individuals younger than 4 years of age ( d = -2.924) and relying upon convenience samples ( d = -4.828 for clinical samples, -2.734 for convenience samples, and -1.422 for community samples). Directions for future research and implications for using the Social Communication Questionnaire to screen for autism spectrum disorder are discussed.
