Convergence between Individual Measures of Peer Affiliation: Within-Individual Interclass Correlations

Variable	1 ([95% CI] p)	2 ([95% CI] p)	3 ([95% CI] p)	4 ([95% CI] p)	M (SD)
1. Continuous measure of social interaction		.54 ([−.07, ∞] .07)	.79 ([.38, ∞] .01)	−.63 ([−∞, −.07] .04)	0.00 (0.50)
2. Child-reported likeability	−.21 ([−.71, ∞] .30)		.56 ([−.04, ∞] .06)	−.55 ([−∞, .05] .06)	0.26 (0.09)
3. Teacher-reported sociability	.70 ([.19, ∞] .02)	−.15 ([−.68, ∞] .35)		−.73 ([−∞, −.25] .01)	2.79 (0.23)
4. Teacher-reported withdrawal	−.79 ([−∞, −.38] .01)	.10 ([−∞, .65] .40)	−.72 ([−∞, −.23] .01)		1.25 (0.17)
M (SD)	0.00 (0.60)	0.23 (0.10)	2.43 (0.48)	1.25 (0.35)

Note. N=9 children. Fall 2017 correlations below the diagonal and spring 2018 correlations above the diagonal. Continuous measure scores were z standardized within waves and averaged across waves. Likeability represents the number of nominations a child received from classmates, divided by the number of nominators. Sociability and withdrawal were rated on a scale ranging from 1 (never) to 3 (always), averaged across reporters. One sided confidence intervals (in brackets) and p-values are presented.
