Note. Intimate partner abuse variables are the dichotomous predictors (yes, no). Postpartum mental health variables are the continuous outcomes. OCD = obsessive-compulsive disorder. PTSD = posttraumatic stress disorder. Multivariate F ratios were generated from Wilks’ Lambda’s statistic. ^aMultivariate df = 5, 71. ^bUnivariate df = 1, 75. η_p ² = partial eta-squared. *p < .05. **p < .01. ***p < .001.
