Coefficient estimates of the cross-lagged model.

Informant of sibling
aggression		 β23 β41 β21 β43 ψ13 ψ24
Model 1 Sibling 0.08* 0.04 0.37** 0.40** 0.10** 0.08**
Model 2 Mother 0.11** 0.01 0.61** 0.40** 0.13** 0.10**
Model 3 Father 0.12** 0.00 0.67** 0.40** 0.10** 0.03

Note. β23 represents cross-lagged effect from sibling aggression at Time 1 to exerternalizing problems at Time 2; β41 indicates the cross-lagged effect from externalizing problems at Time 1 to sibling aggression at Time 2; β21 and β43 indicate the stabilities of sibling aggression and externalizing problems between Time 1 and Time 2, respectively; ψ13 and ψ24 are the contemporaneous correlations between sibling aggreession and externalizing problems at Time 1 and 2, respectively.
