ABSTRACT
BACKGROUND:
Prior work has examined the links between pre- and postnatal maternal distress and infant negative affectivity; however, there is little understanding about how the continuity of infant exposure to pre- and postnatal maternal distress relates to infant development. This study investigated the continuity of maternal pre- and postnatal depressive and anxiety symptoms and their relations with infant fear among 391 mother-infant dyads. An additional aim was to consider infant sex as a moderating factor.METHODS:
Maternal anxiety and depressive symptoms were measured during gestational weeks 14, 24 and 34 and 3 and 6 months postpartum. Subsequently, infant fear was measured using mother reports (IBQ-R) at 6 months and in a laboratory setting (Lab-TAB Masks episode) at 8 months. Using growth mixture modeling, a three-class model describing the course of maternal symptoms across pregnancy and the early postnatal period was identified, consisting of mothers with "Consistently Low Distress", "Prenatal-Only Distress", and "Consistently High Distress".RESULTS:
Infant girls exposed to prenatal-only maternal distress were higher in observed fear than infant boys exposed to prenatal-only distress. Infant girls exposed to consistently high distress also showed lower observed fear than their counterparts exposed to prenatal-only maternal distress.LIMITATIONS:
The main limitation of the study is the relatively small group size within the Consistently High subgroup.CONCLUSIONS:
The findings suggest that girls might be particularly sensitive to maternal distress, and that prenatal-only and continuous distress exposure are differentially related to female infant fear.Palabras clave
