ASD: autism spectrum disorder; ADHD: attention deficit hyperactivity disorder; BASC-2: Behavioral Assessment System for Children–Second Edition; SRS: Social Responsiveness Scale; VABS-II: Vineland Adaptive Behavior Scales–Second edition.

Scores in the severely impaired range on the SRS and in the low range on VABS-II (≥2SD below the mean) are designated in bold.

^a,b,c

Different superscripts designate significantly different between-group mean scores using Bonferroni post hoc multiple comparisons (p < .05); groups with same superscripts are not significantly different from each other.

Scores in the mild-to-moderately impaired range on the SRS and in the moderately low range (≥1 and <2SD below the mean) on the VABS-II.

p < .005 (corrected p using Bonferroni correction).
