Personality and risk for postpartum depressive symptoms

Area of Science:

• Psychiatry and Mental Health
• Perinatal Psychology
• Epidemiology of Maternal Health

Background:

• Postpartum depression (PPD) affects 10-15% of new mothers, representing a significant childbirth complication.
• Understanding the predictors of PPD is crucial for timely intervention and improved maternal well-being.

Purpose of the Study:

• To investigate the association between specific personality factors and the development of postpartum depressive symptoms (PPDSs).
• To identify personality traits that may serve as risk indicators for PPD in non-depressed pregnant women.

Main Methods:

• Prospective study (BASIC study) involving 1037 non-depressed pregnant women.
• Assessment of depressive symptoms using the Edinburgh Postnatal Depression Scale (EPDS) and major depression diagnosis via the Depression Self-Rating Scale (DSRS).
• Evaluation of personality traits using the Swedish Universities Scale of Personality (SSP).

Main Results:

• High levels of neuroticism in late pregnancy were strongly associated with an increased risk of PPDSs at 6 weeks and 6 months postpartum (aORs ranging from 3.4 to 3.9).
• Trait anxiety (somatic and psychic) and mistrust were also linked to a higher risk of developing PPDSs.
• The association between high neuroticism and PPD remained significant even after adjusting for confounders.

Conclusions:

• Neuroticism is a significant predictor of postpartum depression in women who were not depressed during pregnancy.
• Personality assessment, particularly neuroticism, could aid healthcare professionals in identifying at-risk mothers for targeted support.
• Early identification of personality traits like neuroticism and anxiety may facilitate preventative strategies for postpartum depression.
