Note. Contemp. = Contemporaneous. Bolded items reflect significant contrasts. All significant contrasts p < .008 following Bonferroni correction.

^*Descriptive statistics for IPV variables are means and standard deviations.

^†Descriptive statistics for contemporaneous variables are estimated marginal means and standard errors.
