Computer-based mother-infant interaction analysis and mental functioning in postpartum depression.

BACKGROUND: Among mothers suffering from postpartum depression (PD), 10-13% additionally experience a mother-infant interaction disturbance that causes a severe mental health risk for the infant. Besides depressive symptomology, the underlying factors promoting dysfunctional maternal interaction behavior have not yet been sufficiently investigated. Therefore, we examined potential relationships between computer-based mother-infant interaction among postpartum depressed dyads and maternal mental functioning. METHODS: Mother-infant interaction was video-recorded and evaluated via a computer-based micro-interaction analysis program (INTERACT). We included only 25 hospitalized mother-infant dyads that fulfilled the diagnostic criteria of PD and tested mothers on their mental functioning (empathy, theory of mind, meta-cognition and alexithymia). RESULTS: Behavioral interaction analyses indicated that mothers with PD were prone to inactive maternal behavior, less positive maternal behavior along with more rejective behavior and also disengaged affect towards the infant. Distortions in mothers' mental functioning may have had an influence on the dysfunctional patterns of mother-infant dyads. CONCLUSIONS: Cognitive and social functioning could be an influencing factor on dysfunctional maternal interaction behavior. Early detection of distortions of mental processing in expectant mothers might help to inhibit the clinical manifestation of dysfunctional mother-infant bonding and negative child outcome in PD.

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.

Differences in interactional behaviour in postpartum depression with and without pre-existing mental disorder.

BACKGROUND: Mothers with postpartum depression (PPD) show impaired affects and behaviour patterns in the mother-child interaction, which affects an infant's emotional and cognitive development and the maternal course of disease. However, impairment of the mother-child relationship does not occur in every case of PPD. AIM: The aim of this exploratory-descriptive video-based study was to investigate the possible associations between mother-child interactions and aspects of maternal biography and clinical history, with a focus on pre-existing mental disorder. METHODS: Sixty-two mother-child dyads (31 mothers with PPD and pre-existing mental disorders and 31 mothers with PPD but no further mental disorder) hospitalized at the mother and baby unit (MBU) of the LWL-Hospital Herten were included in this study. The Marcé Clinical Checklist and the "Mannheimer Beurteilungsskala zur Erfassung der Mutter-Kind-Interaktion im Säuglingsalter" (MBS-MKI-S) were used to explore sociodemographic and clinical parameters, and video-based interaction behaviour was examined. RESULTS: Mother-infant interaction behaviour showed a significant group difference on the MBS-MKI-S-Vm subscale (variability in maternal behaviour) before psychiatric treatment (exact Mann-Whitney U test: U = 555, p = 0.023), with higher scores in mothers with a pre-existing mental disorder. Furthermore, significant differences were shown on the MBS-MKI-S-RSm (maternal reactivity/sensitivity) (U = 259, p = 0.019) and MBS-MKI-S-Rc (child's reactivity) subscales at discharge (U = 251, p = 0.021). Among mothers with a pre-existing diagnosis, the MBS-MKI-S-Tm (maternal tenderness) and MBS-MKI-S-Rc (child's reactivity) subscales were significantly correlated after treatment. CONCLUSIONS: Mothers with PPD and a pre-existing mental disorder displayed significantly more behavioural variability than mothers with only PPD. Maternal behaviour seems to influence the child's responsive behaviour; thus, mothers and their children can benefit from inpatient treatment at an MBU. Further investigations with larger samples should be conducted.
