Maternal childhood emotional abuse predicts Chinese infant behavior problems: Examining mediating and moderating processes.

Abstract

The current study examined the mediating effect of maternal negative expressiveness as well as the moderating effects of infant inhibitory control (IC) in the association between maternal childhood emotional abuse (CEA) and infant behavior problems. Drawing from 207 families from mainland China, 2-wave data were reported in this study when the infants were 6 months (T1) and 14 (T2) months. Mothers (Mean age = 32.85 years, SD = 4.04) reported their CEA on the Childhood Trauma Questionnaire-Short Form (CTQ-SF) at T1, and their negative expressiveness on the Self-Expressiveness in the Family Questionnaire (SEFQ) at T2. The Infant-Toddler Social and Emotional Assessment (ITSEA) and a reverse categorization task were used to measure infant behavior problems and IC at T2, respectively. The results showed that T1 maternal CEA, rather than physical and sexual abuse, uniquely predicted T2 negative expressiveness. Maternal negative expressiveness significantly mediated the positive relations of maternal CEA and infant externalizing, internalizing and dysregulation problems. In addition, the moderated mediation model showed that the association between maternal negative expressiveness and infant dysregulation problems was moderated by infant IC. Specifically, the mediating pathway from maternal CEA to dysregulation problems through maternal negative expressiveness was significant, only for infants with poor IC. The results were robust even after controlling for family socio-economic status (SES), maternal childhood physical and sexual abuse. The importance of mediating and moderating processes in understanding the effect of maternal emotional abuse during childhood on infant behavior problems is discussed.
