Note. ELA = Early-Life Adversity, IPV = Intimate Partner Violence.
h2, c2, e2 = Standardized proportions contributed by additive genetic, shared and unique environmental factors, respectively to the variable variances (diagonals) and their covariances (off-diagonals).
As, Cs and Es = Standardized variable-specific additive genetic, shared and individual-specific influences.
