||The Adult Temperament Questionnaire (ATQ) was adapted from the Physiological Reactions Questionnaire developed by Derryberry and Rothbart (1988). It is a self-report model of temperament that includes general constructs of effortful control, negative affect, extraversion/surgency, and orienting sensitivity. The general constructs are referred to as factor scales (i.e., they have resulted in superfactors) and the sub-constructs are referred to as scales. The ATQ long form includes 177 items and the short form 77 items. Both forms include the same constructs. In addition to including general constructs and sub-constructs, the long form also subdivides many of the sub-constructs into homogeneous item clusters (see long form scoring instructions). These questionnaires are to be used for research purposes only.
