p-value is from investigations of differences in maternal mental health among full-term compared to preterm mother-infant dyads using independent samples t tests (for continuous variables) and chi-square analysis (for categorical variables). Bolded values indicate significance, p <.05.
p-value is from investigations of differences in maternal mental health among full-term compared to preterm mother-infant dyads using linear (for continuous variables) and logistic (for categorical variables) regression models, controlling for race, type of delivery, and siblings, p<.05. Note: type of delivery, race, and number of children were all related to each (p<.05) in chi-square analysis but all were included in the model. Analyses re-run controlling only for c-section and the findings remained largely unchanged.
Postpartum depression symptoms defined as having a score of >10 on the EPDS
PTSD symptoms defined as having a score of >19 on the Modified PPQ
Psychological distress was defined as scoring above the 75th percentile on the PSS, EPDS, STAI (state), or modified PPQ.
