Abstract
Supportive parent emotion socialization has been associated with greater child emotion understanding and expression and lower levels of externalizing behavior problems, with limited understanding on parent emotion socialization in toddlerhood. The current study examined the developmental trajectory of emotion socialization via emotion talk in mothers of toddlers from a predominantly Latine sample. Participants were 101 mother-toddler dyads assessed over three time points from ages 12-25 months. Overall, maternal emotion talk remained relatively stable over time, although there was a significant decrease between the first and second assessments before returning to initial rates at the third assessment. Maternal emotion talk did not predict child externalizing behavior over time. Interestingly, however, greater toddler externalizing behavior problems was associated with an increase in maternal emotion talk over time. These findings suggest maternal emotion talk is relatively stable for parents of children who are low on externalizing behaviors and may fluctuate (i.e., slowly increase) for mothers of children who are high in externalizing behaviors. Understanding these mechanisms further could help inform how we implement and personalize parenting interventions.
