Expressive Language	−.15	−.22^*
Total Language	−.16^*	−.24^***
Non-Verbal Ability	−.57^***	−.52^***
Partial Correlations (adjusting for cognitive variables)
ASD Diagnosis (receptive language)	.63^***	.40^***
ASD Diagnosis (non-verbal ability)	.52^***	.41^***
ADOS Total Severity (receptive language)	.40^***	.59^***
ADOS Total Severity (non-verbal ability)	.18	.58^***
Partial Correlations (adjusting for behavior problems)
ASD Diagnosis (CBCL total problems)	.67^***	.49^***
ADOS Total Severity (CBCL total problems)	.47^***	.67^***

Note. All correlations with Autism Diagnostic Observation Schedule (ADOS) Total Severity are non-parametric (Spearman’s) bivariate or partial correlations. ASD = autism spectrum disorder; CBCL = Child Behavior Checklist; SRS = Social Responsiveness Scale
