Formal tests of moderation were conducted next. As seen in Table 2, the best-fitting model was the linear C moderation model. Estimated paths and moderators from the full and best-fitting linear models are presented in Table 3. Unstandardized or absolute genetic and environmental variance contributions to CP at each level of parent–child conflict are plotted in Fig. 2. A and E contributions to CP were significantly greater than zero and small to moderate in magnitude across all levels of conflict. C contributions, by contrast, were near zero at the lowest levels of conflict (the ‘c’ path was small and non-significant), but increased dramatically (and significantly) with increasing levels of conflict. Indeed, shared environmental influences on CP at high levels of parent–child conflict were many-fold larger than those at low levels of conflict1†.
