RT Article T1 Profiles of Disruptive Behavior Across Early Childhood: Contributions of Frustration Reactivity, Physiological Regulation, and Maternal Behavior JF Child development A1 Calkins, Susan D. A2 Keane, Susan P. A2 Hill, Ashley L. A2 Degnan, Kathryn Amey LA English YR 2008 UL https://krimdok.uni-tuebingen.de/Record/1866309943 AB Disruptive behavior, including aggression, defiance, and temper tantrums, typically peaks in early toddlerhood and decreases by school entry; however, some children do not show this normative decline. The current study examined disruptive behavior in 318 boys and girls at 2, 4, and 5 years of age and frustration reactivity, physiological regulation, and maternal behavior in the laboratory at 2 years of age. A latent profile analysis resulted in 4 longitudinal profiles of disruptive behavior, which were differentiated by interactions between reactivity, regulation, and maternal behavior. A high profile was associated with high reactivity combined with high maternal control or low regulation combined with low maternal control. Results are discussed from a developmental psychopathology perspective DO 10.1111/j.1467-8624.2008.01193.x
