Note: Correlations for the Maternal Lifestyle Study (MLS) are presented above the diagonal, and correlations for the Infant Development, Environment, and Lifestyle study (IDEAL) are presented below the diagonal.

Correlations were computed using maximum likelihood with robust standard errors. Bolded values indicate alpha significance at p < .05.

^a1 = less than high school, 2 = high school, 3 = greater than high school (MLS), and 1 = high school or greater (IDEAL).

^bSocioeconomic status 1 = Hollingshead 5.

^c1 = is married (MLS) or has romantic partner (IDEAL).

^dWhite racewas used as a reference group.

^e1 = male sex.

^fModerately low reactive, moderately dysregulated.

^gGeneral reactive, well regulated.

^hNegative reactive, dysregulated.

ⁱHigh positive affect, well regulated.
