Note: Cell entries summarize Tables 3 and 4. Standard errors are calculated using second-order Taylor series and exact variance estimating procedures (Goodman 1960). The column labeled ‘%’ describes the percent reduction in the heritability of resilience estimate presented in models 2 and 4 of Table 2. All data come from the twin sample of the National Survey of Midlife Development in the United States (MIDUS), 1995–1996 (Brim et al., 1996). A total of 527 twin pairs are used in these analyses (MZm(129); MZf(155); DZm(104); DZf(139).
