In 1972, psychiatrist, psychoanalyst, and cognitive therapy scholar Aaron T. Beck published "Depression: Causes and Treatment." He was dissatisfied with the conventional Freudian treatment of depression, because there was no empirical evidence for the success of Freudian psychoanalysis. Beck's book provided a comprehensive and empirically-supported theoretical model for depression—its potential causes, symptoms, and treatments. In Chapter 2, titled "Symptomatology of Depression", he described "cognitive manifestations" of depression, including low self-evaluation, negative expectations, self-blame and self-criticism, indecisiveness, and distortion of the body image.
