Six subscales were created using 63 items from the Early Adolescent Temperament Questionnaire – Revised (EATQ-R; Capaldi & Rothbart, 1992) and the Children’s Behavior Questionnaire (CBQ; Rothbart, 1996): Activation control, attention, inhibitory control, frustration, depressive mood, and positive emotions—Children reported how well each statement describes them.
