Higher scores on SCDC represent more social communication problems. Lower scores in DANVA means a poorer performance in identifying emotions/more misattributions
ns not significant after adjusting for multiple comparisons using the Bonferroni-Holm method
^aMinimally adjusted model: adjusted for child age, child gender, and tester
^bFully adjusted model: adjusted for child age, child gender, tester, maternal education, ethnic background and parity
