Linear Contrasts between Cross-Lagged Effects Generated from SEM Models

Linear Contrast	Coef.	SE	95% CI
(Early Exp → Late HSJE) – (Early HSJE → Late Exp)	−0.05	0.13	[−0.31, 0.22]
(Early Rec→ Late HSJE + FI) – (Early HSJE + FI → Late Rec)	0.01	0.14	[−0.27, 0.29]
(Early Rec → Late HSJE) – (Early HSJE → Late Rec)	−0.22	0.12	[−0.46, 0.03]
(Early Exp→ Late HSJE + FI) – (Early HSJE + FI → Late Exp)	0.03	0.12	[−0.21, 0.28]

Note. CI = Confidence Interval, Exp = Expressive Vocabulary, FI = Follow-in Talk, HSJE = Higher Order Supported Joint Engagement, Rec = Receptive Vocabulary, SE = Standard Error, SEM = Structural Equation Modeling
