Supports genetic research on Type D personality; leaves open clinical utility for cardiovascular risk assessment.
Observational (n=30,433)
Type D personality and its subcomponents are highly heritable, with a shared genetic basis for negative affectivity and social inhibition.
Effect estimate: 49% (95% CI 47-51)
Li‐Gao et al. (2020) conducted an observational in Type D personality (n=30,433). Genetic and environmental factors was evaluated on Broad-sense heritability of the continuous Type D personality measure (NAxSI) (49%, 95% CI 47-51). Type D personality and its subcomponents are substantially heritable, with broad-sense heritability for the continuous Type D measure estimated at 49%.
