Capacities for meta-cognition, social cognition, and alexithymia in postpartum depression.

Postpartum depression (PPD), a female-specific disorder, is the most common medical complication associated with childbirth (10-20%). The pathological relevance of emotion processing, meta-cognition, alexithymia, and social cognition to PPD is unclear. We tested 25 mothers with PPD (mean age: 30.72 ± 5.76 years) and 25 healthy mothers (mean age: 32.03 ± 3.54 years) for alexithymia (Toronto Alexithymia Scale) and evaluated cognitive empathy (Faux Pas Test), affective empathy (Interpersonal Reactivity Index), meta-cognition (Meta-Cognitions Questionnaire), sociodemographic and clinical-psychometric characteristics and personality dimensions. Mothers with PPD showed higher levels of neuroticism and more anxiety-depressive characteristics. Their metacognitive abilities were significantly altered and they more often had alexithymia. Significant correlations between alexithymia and meta-cognition, trait anxiety, and neuroticism were found. Alexithymia, neurotic personality traits, and dysfunctional meta-cognition appear more frequently in PPD women than healthy women. Social cognition abilities were not significantly altered. Alexithymia and metacognitive distortions play important roles in the pathogenesis of PPD. Dysfunctional meta-cognition, neuroticism, and alexithymia may be risk factors that should be detected early in expectant mothers to prevent the development of PPD.
