Early Adolescent Temperament Questionnaire - Effortful control (EATQ-EC)

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).
