Fomby finds living with step- or half-siblings linked to higher aggression among 5 year olds
"Aggressive behavior more common in children with half- and step-siblings" - Michigan News. 1/26/2016.
Today, about 1 in 6 US children live with step- or half-siblings at age 4. Paula Fomby and colleagues studied the frequency of aggressive behaviors - tantrums, physical aggression, property destruction, etc. - among kindergarten students. They found that children living with step- or half-siblings had more of these behaviors than their peers whose parents had the same union status but whose households didn't include step/half-siblings. Fomby says potential explanations for this difference include an uneven distribution of materials and emotional resources across children in these households, as well as the absence of one parent.
