Prenatal obsessive beliefs predict postpartum obsessive-compulsive symptoms: a prospective study

Area of Science:

• Psychiatry
• Psychology
• Cognitive Science

Background:

• Postpartum obsessive-compulsive (OC) symptoms are prevalent, affecting a significant portion of women after childbirth.
• Understanding the predictors of postpartum OC symptoms is crucial for timely intervention and support.
• Cognitive patterns, specifically obsessive beliefs, are implicated in the development and maintenance of OC symptoms.

Purpose of the Study:

• To investigate whether specific cognitive patterns during pregnancy predict the onset and severity of postpartum obsessive-compulsive symptoms.
• To examine the relationship between prenatal obsessive beliefs and postpartum OC symptom severity and diagnosis.
• To explore the role of psychological distress as a potential confounder in this relationship.

Main Methods:

• A longitudinal study design involving 256 pregnant women assessed at three time points: mid-pregnancy, 6 weeks postpartum, and 6 months postpartum.
• Utilized interview and self-report measures to assess obsessive-compulsive symptoms, psychological distress, and obsessive beliefs.
• Statistical analyses controlled for baseline OC symptoms and distress to isolate the predictive effect of prenatal cognitive factors.

Main Results:

• Postpartum OC symptoms were highly common, with prevalence rates of 87.1% at 6 weeks and 74.5% at 6 months postpartum.
• Stronger obsessive beliefs during pregnancy were significantly associated with greater postpartum OC symptom severity.
• Prenatal obsessive beliefs predicted a higher likelihood of an obsessive-compulsive disorder (OCD) diagnosis at 6 months postpartum, independent of baseline factors.

Conclusions:

• Prenatal cognitive risk factors, specifically obsessive beliefs, are important predictors of postpartum obsessive-compulsive symptoms.
• These findings underscore the clinical significance of assessing and addressing cognitive patterns during pregnancy for the prevention of postpartum OCD.
• The results support cognitive-behavioral models in understanding the etiology of postpartum OCD and inform potential therapeutic targets.
