Convergence between Dyadic Measures of Peer Affiliation: Within-Dyad Intraclass Correlations

Variable	1 ([95% CI] p)	2 ([95% CI] p)	3 ([95% CI] p)	M (SD)
1. Dyadic continuous measure of social interaction		.34 ([−.16, ∞] .06)	.24 ([−.33, ∞] .10)	0.00 (0.61)
2. Child-reported Friendship	−.24 ([−1.0, ∞] .37)		.84 ([.71, ∞] .001)	0.28 (0.66)
3. Teacher-reported Friendship	.50 ([.12, ∞] .01)	.32 ([−.19, ∞] .06)		0.39 (0.73)
M (SD)	0.00 (0.93)	0.83 (0.88)	0.28 (0.57)

Note. N=36 dyads. Fall 2017 correlations below the diagonal and spring 2018 correlations above the diagonal. Dyadic continuous measure scores represent the number of vocalizations one child made in the presence of another child, divided by the amount of time the two children were in the classroom together; for each dyad, scores were averaged across partners, z-standardized within waves, and averaged across waves. Child-report scores represent the number of times during a semester that two children were reciprocated friends. Teacher-report scores represent the number of times during a semester that teachers identified two children as friends. One sided confidence intervals (in brackets) and p-values are presented.
