Note.
p < .01.
Covariation removed for other traits in the same scale (e.g. Residual correlation with Neuroticism removes covariation with other 4 of Big Five traits and Agency, while residual correlation with Well-Being removes covariation with other 9 MPQ traits). Correlations are reported after transformation procedures and after regressions that control for age and sex. Maximum likelihood 95% confidence intervals in brackets; those which do not contain zero are deemed to be significant and in bold. In all bivariate cases, the reduced AE model had a lower AIC value than the ADE or ACE models, so only results from AE models are reported for genetic and environmental correlations. Well-Being, Social Potency, Achievement, and Social Closeness are subsumed by Positive Emotionality. Stress Reactivity, Aggression, and Alienation are subsumed by Negative Emotionality. Control, Traditionalism, and Harm Avoidance are subsumed by Constraint.
