The complex effects of maternal expectations on postpartum depressive symptoms: when does a protective factor become a risk factor?

Purpose: The present study assessed the effects of several prenatal maternal expectations on postpartum depression (PPD), while considering two relevant factors - incongruence between planned and actual birth and the rigidity of the birth plan - that can affect whether maternal expectations act as protective factors or risk factors for PPD.

Methods: Primiparous women (N = 527) were recruited to a longitudinal study about women's birth choices and experiences. At time 1, during pregnancy, women completed a questionnaire assessing prenatal depression, preferred birth plan, birth plan flexibility-rigidity and maternal expectations (i.e. Natural-Fulfillment, Infant-Reflects-Mothering, Sacrifice). At time 2, two-months post-partum, they reported their actual birth mode and answered a questionnaire assessing their PPD symptoms.

Results: Natural-fulfillment maternal expectations were negatively related to PPD symptoms. Yet, the interaction of high natural-fulfillment expectations with an unfulfilled birth plan and the rigidity of the birth plan, served as a risk factor for PPD symptomatology.

Conclusions: Understanding the conditions under which specific prenatal maternal expectations serve as a risk factor for PPD, can help healthcare providers identify women who are at high risk for developing PPD symptoms and plan preemptive interventions.
