effect is expected, so it is inappropriate to estimate the G-E correlation63. Therefore, for independent stressful life events, we only allowed for moderation on the unique variance in EXT. While not ideal, this approach allowed us to examine at least some of the effect of highly relevant environmental stressors (e.g., parental discord, poverty, family legal and mental health problems), and whether the mechanism of their effect was similar or different to that of other environmental risk factors.
