Comparison of ADOS scores by sex

ADOS subscales	Male mean (SD)	Female mean (SD)	t‐value	p‐value	Hedges' g
Communication (Comm)	3.08 (1.62)	2.28 (1.47)	2.93	0.004	0.51
Reciprocal social interaction (RSI)	6.02 (2.65)	4.48 (2.84)	3.25	0.001	0.56
Comm and RSI	9.11 (3.89)	6.76 (3.84)	3.47	<0.001	0.60
Stereotypical behaviors and restricted interests	1.60 (1.50)	1.42 (1.72)	0.65	0.514	0.11

Note: p‐values are based on two sample t tests between the total sample of males and females (n = 145). Hedges' g is an effect size measure typically used for unequal sample sizes.

Abbreviations: ADOS, autism diagnostic observation schedule; SD, standard deviation.
