ABSTRACT Background The postpartum period is a vulnerable time for the development of depression. While perinatal depression has been well studied, intrusive thoughts related to the infant and classic obsessive-compulsive (OC) symptoms (e.g. chequering, ordering and cleaning) are also common in the postpartum and less well understood. Objective The present study investigated the associations among depressive symptoms, intrusive thoughts, and OC symptoms and their relation to the quality of the mother–infant relationship, particularly in the realm of maternal responsiveness. Methods Participants (N = 228) were recruited after delivery from a large Midwestern academic medical centre. At 2 and 12-week postpartum, participants completed self-report questionnaires that assessed demographics, depressive and OC symptoms, postpartum-specific intrusive thoughts and accompanying neutralising strategies, and maternal responsiveness. Results At 12-week postpartum, maternal responsiveness was significantly lower for participants that endorsed intrusive thoughts, neutralising strategies or OC symptoms of clinical significance. More severe intrusive thoughts and neutralising strategies were associated with maternal responsiveness but not predictive after accounting for depressive symptoms; depressive symptoms were associated with lower levels of maternal responsiveness across the postpartum. Conclusions A sizable number of postpartum women experience clinically significant postpartum-specific intrusive thoughts and utilise neutralising strategies, especially in the context of postpartum depressive symptoms. Depressive symptoms have the most influence on maternal responsiveness but it is also important to target intrusive thoughts and OC symptoms in the context of postpartum depression to promote the welfare of new mothers and their offspring.
