The current project tested a holistic model of surgency based on temperament theory (Rothbart & Derryberry, 1981) that used a multi-trait multimethod approach to integrate multiple domains of regulation and reacitivity. Four models were tested that included measures of physiological regulation, behavioral regulation, emotion regulation, and parent-reported temperament. A single model emerged that accounted for biological, behavioral, affective, and parent-reported, domains of surgency in 3.5 year old children. This model comprised high levels of positive affect, fidgeting, impulsivity, and RSA suppression loading onto a single latent factor of high surgency. This work contributes to the temperament literature by providing initial evidence for a holistic composite of surgency during early childhood that is consistent with classic temperament definitions of surgency.enPreschool childrenPersonalityTemperamentEmotionsThesisCopyright 2017 by Mara June Canen
