IBQ = Infant Behavior Questionnaire; FFSFP = Face-to-Face Still Face Procedure; Reactivity = Difference from normal talk to still face period (still face—talk); Regulation = Difference fromstill face to reunion period (reunion—still face).

¹Affect coding from FFSFP was only available at the 6-month visit (non-ODD N=12; ODD-only N=12; ODD+CU N=6)
