The Impact of Postnatal Depression on Infant Development

Early infant interest in their mother's face is driven by an experience based face processing system, and is associated with maternal psychological health, even within a non clinical community sample. The present study examined the role of the voice in eliciting infants' interest in mother and stranger faces and in the association between infant face interest and maternal psychological health.Infants aged 3.5-months were shown photographs of their mother's and a stranger's face paired with an audio recording of their mother's and a stranger's voice that was either matched (e.g., mother's face and voice) or mismatched (e.g., mother's face and stranger's voice). Infants spent more time attending to the stranger's matched face and voice than the mother's matched face and voice and the mismatched faces and voices. Thus, infants demonstrated an earlier preference for a stranger's face when given voice information than when the face is presented alone. In the present sample, maternal psychological health varied with 56.7% of mothers reporting mild mood symptoms (depression, anxiety or stress response to childbirth). Infants of mothers with significant mild maternal mood symptoms looked longer at the faces and voices compared to infants of mothers who did not report mild maternal mood symptoms. In sum, infants' experience based face processing system is sensitive to their mothers' maternal psychological health and the multimodal nature of faces.

A literature search for the past 15 years was conducted using the MEDLINE database, and by reviewing the bibliographies of the retrieved articles. Of particular interest were the prospective longitudinal cohort studies in which mothers were recruited during their pregnancy or postpartum period, and the children were assessed at regular intervals.

SummaryBackground: Considering the adverse effects of postpartum depression on both mother and infant, a screening instrument for early diagnosis seems to be of importance.Aims: To assess the psychometric properties of the Persian version of Edinburgh Postnatal Depression Scale (EPDS) on a sample of Iranian postpartum women.Method: The EPDS was translated and back-translated in the standard method. The questionnaire was completed by 600 postpartum women. Hundred cases with an EPDS score of !9 and 100 cases with an EPDS of <9 were randomly selected for interview. Sensitivity, specificity, positive likelihood ratio, and receiver operating characteristics were calculated by comparing the EPDS sum score against the DSM-IV diagnoses. The correlation coefficient of the EPDS score with GHQ-12 score was calculated. Principal component analysis and internal consistency were assessed.Results: The best cutoff scores for major depression were 12=13 with a sensitivity and specificity of 95.3% and 87.9%, respectively. The correlation coefficient of the total score of the Persian version of EPDS with the GHQ-12 total score was 0.76 (P < 0.001). A two-factor solution was selected as the most appropriate model based on both values and the score plot. The coefficient alpha for the whole scale was 0.83.Conclusion: The Persian version of EPDS is a reliable and valid measure for detecting postpartum depression. Furthermore, it seems acceptable to patients and a valid screening instrument for depression in postpartum women.
