The Relation between Specific Parenting Behaviors and Toddlers' Early Anxious Behaviors is Moderated by Toddler Cortisol Reactivity.

The Relation between Specific Parenting Behaviors and Toddlers' Early Anxious Behaviors is Moderated by Toddler Cortisol Reactivity. J Abnorm Child Psychol. 2019 Feb 22;: Authors: Kalomiris AE, Phelps RA, Kiel EJ Abstract Differential susceptibility theory posits that neurobiological reactivity (e.g., cortisol levels) should be considered as an individual index of susceptibility to both positive and negative environments. The current investigation separately examines cortisol reactivity and total concentration in toddlerhood as moderators of the longitudinal relation between maternal protection and encouragement of independence and increases or decreases in observed anxious behaviors, respectively. A total of 119 mother-toddler dyads participated in a laboratory visit when toddlers were 12- to 18-months-old. Mothers reported on their parenting behaviors and toddlers participated in a novelty episode from which their anxious behaviors were coded. Toddlers provided three saliva samples, yielding measures of cortisol reactivity and total cortisol concentration. One year later, dyads returned to the laboratory where toddlers participated in another novelty episode to observationally assess anxious behaviors. Results revealed that maternal protection tended to relate to greater increases in anxious behaviors one year later only for toddlers who displayed high cortisol reactivity. Cortisol reactivity also moderated the relation between mat...
