RSA instability in mothers of preschoolers and adolescents is related to observations of supportive parenting behaviors
Respiratory sinus arrhythmia (RSA; a measure of respiratory modulation of vagal control of heart rate) is a dynamic process. For mothers, RSA functioning has been associated with depressive symptoms and coincides with supportive parenting. However, research has largely focused on RSA suppression (i.e., difference score from rest to stress task). The present study examined depressive symptoms and supportive parenting with RSA instability—a dynamic measure of the magnitude of RSA change across a task. In two samples of mothers (N = 210), one with preschoolers (Study 1: n = 108, Mage = 30.68 years, SD = 6.06, 47.0% Black, 43.0% White) and one with adolescents (Study 2: n = 102, Mage = 35.51, SD = 6.51, 75.2% Black), RSA instability was calculated during an interaction task. In both studies, instrumental supportive parenting behaviors were negatively related to RSA instability. Findings provide preliminary support for RSA instability as an indicator of physiological dysregulation for mothers.
期刊介绍：
Developmental Psychobiology is a peer-reviewed journal that publishes original research papers from the disciplines of psychology, biology, neuroscience, and medicine that contribute to an understanding of behavior development. Research that focuses on development in the embryo/fetus, neonate, juvenile, or adult animal and multidisciplinary research that relates behavioral development to anatomy, physiology, biochemistry, genetics, or evolution is appropriate. The journal represents a broad phylogenetic perspective on behavior development by publishing studies of invertebrates, fish, birds, humans, and other animals. The journal publishes experimental and descriptive studies whether carried out in the laboratory or field.
The journal also publishes review articles and theoretical papers that make important conceptual contributions. Special dedicated issues of Developmental Psychobiology , consisting of invited papers on a topic of general interest, may be arranged with the Editor-in-Chief.
Developmental Psychobiology also publishes Letters to the Editor, which discuss issues of general interest or material published in the journal. Letters discussing published material may correct errors, provide clarification, or offer a different point of view. Authors should consult the editors on the preparation of these contributions.
