AQ, Autism-Spectrum Quotient; ADOS-G, Autism Diagnostic Observation Schedule-Generic; ADI-R, Autism Diagnostic Interview-Revised; AQ50, 50-item AQ; AQ10, 10-item AQ.

^aAll correlation coefficients are bivariate Pearson's r. p Values are two-tailed. The number of observations (n) for each comparison varies because not all participants underwent all assessments.

Correlation significant: * p < 0.05, ** p < 0.001.
