Development and History
Historically, depression was described in psychodynamic terms as "inverted hostility against the self". By contrast, the BDI was developed in a novel way for its time; by collating patients' verbatim descriptions of their symptoms and using these to structure a scale which could reflect the intensity or severity of a given symptom.
Throughout his work, Beck drew attention to the importance of "negative cognitions": sustained, inaccurate, and often intrusive negative thoughts about the self. In his view, it was the case that these cognitions caused depression, rather than being generated by depression.
Beck developed a triad of negative cognitions about the world, the future, and the self, which play a major role in depression. An example of the triad in action taken from Brown (1995) is the case of a student obtaining poor exam results:
- The student has negative thoughts about the world, so he may come to believe he does not enjoy the class.
- The student has negative thoughts about his future, because he thinks he may not pass the class.
- The student has negative thoughts about his self, as he may feel he does not deserve to be in college.
The development of the BDI reflects that in its structure, with items such as "I have lost all of my interest in other people" to reflect the world, "I feel discouraged about the future" to reflect the future, and "I blame myself for everything bad that happens" to reflect the self. The view of depression as sustained by intrusive negative cognitions has had particular application in cognitive behavioral therapy (CBT), which aims to challenge and neutralize them through techniques such as cognitive restructuring.

“Theories of child development and guidelines for parents are not cast in stone. They are constantly changing and adapting to new information and new pressures. There is no “right” way, just as there are no magic incantations that will always painlessly resolve a child’s problems.”
—Lawrence Kutner (20th century)
“Sleep hath its own world,
And a wide realm of wild reality.
And dreams in their development have breath,
And tears, and tortures, and the touch of joy.”
—George Gordon Noel Byron (1788–1824)
“I assure you that in our next class we will concern ourselves solely with the history of Egypt, and not with the more lurid and non-curricular subject of living mummies.”
