Legend: Latent factors and paths correspond to Figure 1. The biometric model for observed marital conflict and parent negativity included four variables in the following order: (1) sociability, (2) aggression, (3) marital quality, and (4) parent negativity. The biometric model for associations between observed marital warmth and parent warmth included four variables in the following order: (1) sociability, (2) anxiety, (3) marital warmth, and (4) parent warmth. Each path name has three components: a lower case letter, followed by two subscripted numbers. The lower case letter and first subscripted number refer to a specific latent genetic (a), shared environmental (c), or nonshared environmental (e) factor. The second subscripted number refers to the specific manifest variable (identified by its order in the model) that is linked to the latent factor via the path. For example, path a12 links latent factor A1 to the second variable in the model; CI=95% Confidence Intervals. Shared environmental estimates are not included in this table because the best-fitting models did not include latent shared environmental effects.
