Table 5.

Correlations between the item-level estimates for cross-rater agreement, rank-order stability, heritability and shared environmental influences.

	Cross-rater agreement	Rank-order stability	Heritability	Shared environment
Cross-rater agreement	.58	.36	.39	−.11
Rank-order stability	.43	.68	.47	−.07
Heritability	.42	.46	.73	−.45
Shared environmental influences	−.06	−.12	−.52	.59

NOTE: Correlations for estimates of item residuals are below the diagonal; correlations for estimates of raw items scores are above the diagonal. On the diagonal are the correlations between respective estimates from items’ raw and residual scores.
