New parenthood as a risk factor for the development of obsessional problems.

Research on emotional disturbance during pregnancy and the postpartum period has focused primarily on mood disorders and psychosis, yet preliminary evidence suggests that early parenthood is also associated with an increased risk for the development and exacerbation of obsessional problems. In this article we describe the nature of "postpartum obsessive-compulsive disorder" (ppOCD) and present a cognitive-behavioural model to account for these signs and symptoms. The model outlines features of early parenthood that might increase vulnerability to ppOCD and proposes a conceptual framework similar to that described in cognitive-behavioural models of OCD in general. The empirical status of the model described herein is discussed, along with suggestions for future research and implications for treatment.
