Dimensional Relationships Between Interpersonal Smile Coordination and Social–Emotional Functioning

	SRS-2 SCI	Vineland-II Socialization	IRI Total
Interpersonal smile coordination	−0.40^*	0.64^***	0.48^*
Youth smile magnitude	−0.35^*	0.04	−0.09
Model F	13.51^***	12.06^***	3.82^*
Adjusted R²	0.42	0.40	0.14

Note. In three separate linear regression analyses, SRS-2 SCI, Vineland-II Socialization, and IRI Total scores were predicted by youth-RA interpersonal smile coordination and youth smile magnitude as a set of predictors. Effects are presented as standardized beta coefficients for ease of comparison across measures. SRS-2 SCI, Social Responsiveness Scale, Second Edition Social Communication and Interaction T-score; Vineland-II Socialization, Vineland Adaptive Behavior Scales, Second Edition Socialization standard score; IRI, Interpersonal Reactivity Index.
