Results of Preliminary Analyses

Variable	1	2	3	4
1. 9-month AOSI score	–	.83^***	.61^**	−.81^***
2. 12-month AOSI score		–	.66^***	−.66^***
3. 9-month MSEL score			–	.80^***
4. 12-month MSEL score
Variable M (SD)		Male		Female

9-month AOSI score		8.07 (6.72)		6.08 (6.13)
12-month AOSI score		5.68 (5.84)		5.37 (5.40)
Variable M (SD)	LR control		TSC/no ASD	TSC/ASD

9-month MSEL score ^**	110.82 (14.61)^a		89.75 (20.25)	76.80 (22.99)^b
12-month MSEL score ^***	107.10 (10.29)^a		87.50 (16.53)^b	68.39 (14.49)^c
9-month AOSI score^***	4.47 (2.62)^a		3.50 (3.87)^a	17.00 (5.51)^b
12-month AOSI score^**	3.29 (3.32)^a		2.80 (2.57)^a	11.31 (6.13)^b

Note. Sample size for correlations ranged from n=26–27. MSEL score from 12 months was used in primary analyses for one infant missing 9-month MSEL. AOSI=Autism Observation Scale for Infants. AOSI total score used in analyses. MSEL=Mullen Scales of Early Learning. ELC=Early Learning Composite. ELC used in analyses. Group differences in MSEL scores examined with ANOVAs. Gender differences in AOSI scores examined with t-tests.
