common to both Marital Quality and Internalizing, and the path unique to Internalizing, for genetic, shared environmental, and unique environmental influences) one at a time. For five of the six moderation parameters, the model with the moderation parameter provided a significantly better fit than the baseline, no-moderation model, as shown in the difference in log likelihood value and smaller AIC values (see Table 3). Concurrently, the confidence intervals around the moderation parameter were significant for the same five models (see Table 4). Only the moderation parameter on the common E path was not a significant improvement over the no-moderation model.
