The cognitive model was originally developed to account for depression, but over the years it has been significantly refined and elaborated (A. T. Beck 1967, 1987; A. T. Beck et al. 1979; D. A. Clark et al. 1999; Scher et al. 2004). The model assumes that the cognitive basis for depression is similar in major depression and dysthymia, although activation of depressogenic thinking styles may be more severe and generalized in major depression. In both major depression and dysthymia, the dominant theme is one of perceived loss or deprivation of valued resources. Aaron Beck (1967) coined the term cognitive triad to refer to the pervasive negativity in views of the self, the individual's personal world, and the future that is characteristic of episodic depression. The negative cognitive triad is evident in the automatic thoughts, beliefs, and assumptions of the depressed individual.
