title: Early Adolescent Temperament Questionnaire-Revised (EATQ-R)

description: YOUth is a large-scale longitudinal cohort study following children from the city of Utrecht and its surrounding areas in their development from pregnancy until early adulthood. The YOUth cohort focuses on neurocognitive development involved in two core characteristics of behavioral development: social competence and behavioral control. YOUth includes children from the general population to cover the whole range of variation in behavioral development, ranging from uncomplicated development, through problem behavior, to psychiatric disorders. To understand why some children develop problematic behavior, and others show resilience, YOUth measures a broad range of biological, child-related and environmental determinants.

YOUth conducts repeated measurements at regular intervals (i.e. 'waves'). Specifically, the study has two inclusion moments: YOUth Baby & Child and YOUth Child & Adolescent. YOUth applies a flexible longitudinal design to the cohorts, meaning that children are measured at broader age ranges (3-year age ranges) at each wave. The main benefit of the flexible age design is that it provides more detailed information on the neurodevelopmental curves over time.

An extensive data set is generated, including 3D-ultrasound sweeps of the fetal brain, eye tracking, EEG, (f)MRI, computer tasks, cognitive measurements and parent-child observations. We also collect a broad range of questionnaires on behavior, personality, health, lifestyle, parenting, child development, use of (social) media and more. Finally, (umbilical) blood samples, buccal swabs, saliva and hair samples are collected at each visit, and stored in the UMC Utrecht Biobank.
description: The Early Adolescent Temperament Questionnaire (EATQ) is designed to specifically tap experiences common to adolescents, and is available in self- and parent-report formats. It assesses temperament and self-regulation via adaptation of scales used in studies of children and adults. It has 10 subscales: Activation Control (the capacity to perform an action when there is a strong tendency to avoid it); Affiliation (the desire for warmth and closeness with others, independent of shyness or extraversion); Attention (the capacity to focus attention as well as to shift attention when desired); Fear (unpleasant affect related to anticipation of distress); Frustration (negative affect related to interruption of ongoing tasks or goal blocking); High Intensity Pleasure (the pleasure derived from activities involving high intensity or novelty); Inhibitory Control (the capacity to plan, and to suppress inappropriate responses); Perceptual Sensitivity (detection or perceptual awareness of slight, low-intensity stimulation in the environment); Pleasure Sensitivity (pleasure related to activities or stimuli involving low intensity, rate, complexity, novelty, and incongruity); and Shyness. Two behavioral scales are also included; Aggression (hostile and aggressive actions, including person- and object-directed physical violence, direct and indirect verbal aggression, and hostile reactivity); and Depressive Mood (unpleasant affect and lowered mood, loss of enjoyment and interest in activities).
description: In YOUth, the Revised version of the EATQ was used, and for adolescents only included the subscales Attention and Inhibitory Control.
