Missing values on change scores ^An=63; ^Bn=52

n indicates the number of individual twins. High high scores on specific environmental factor. Low low scores on specific environmental factor. MZ monozygotic, DZ dizygotic, n.e. could not be estimated due to model conversion problems

^aSignificance of heritability (h²)

^bSignificance of differences in h² of two different groups (high, low).
