Psychosocial predictors of postpartum depression in diverse groups of women

The purpose of this study was to test the extent to which a causal model developed from a theoretical formulation of postpartum depression was consistent with data collected from three groups of postpartum women. In this cross-sectional, correlational design the samples consisted of primarily middle-class, Caucasian mothers of term infants and preterm infants, and low-income, African American mothers of term infants. Instruments included the CES-D Depression instrument, the Postpartum Support Questionnaire, Rosenberg's Sq-Esteem instrument, and a question regarding closeness to partner. The causal model was tested with structural equation modeling. Importance of support, support received, and closeness to partner were significant predictors of both self-esteem and depression, Predictors of postpartum depression are the same across diverse samples of women, as proposed in the causal model.
