摘要
Little is known about the relation between levels of restricted and repetitive behavior (RRB) in infants and parent factors. The present study investigated maternal and psychosocial factors (depressive symptoms, socio-economic status, social support) and mother-infant engagement factors (mind-mindedness, sensitivity, and infant-mother attachment security) as predictors of children's RRB at age 26 months in a sample of 206 mothers and children. Maternal depressive symptoms predicted levels of sensory and motor repetitive behavior and rigid, routinized, and ritualistic repetitive behavior. Lower socioeconomic status also predicted independent variance in children's sensory and motor repetitive behavior. The relations between maternal depressive symptoms and both types of RRB were not mediated through observational measures of maternal sensitivity or mind-mindedness at 8 months, or attachment security at 15 months. The results are discussed in terms of whether stress regulation, self-stimulation, and genetic susceptibility can help explain the observed link between maternal depressive symptoms and RRB in the child.
