Beck's cognitive theory of depression states that depressive thoughts reflecting negative views of self, world, and future (the "cognitive triad") are responsible for the symptoms of depression (Zauszniewski, J. A., & Rong, J. 1999). Beck refers to symptoms as sad mood, lack of sleep or appetite and inability to work. Beck believed that depression was caused due to one’s negative view of self (Zauszniewski, J. A., & Rong, J. 1999). His view was different from other theories that believed that it was the other way around and that depression caused a negative self view. According to Haaga, D. A. F., Dyck, M. J., & Ernst, D. (1991) negative cognitive interpretations of experiences lead to these negative views of self, world, and future. The thoughts become automatic and affect feelings and behavior, leading to depression. Depressed persons view themselves as unworthy, incapable, undesirable, and unlovable. They expect failure, rejection, and dissatisfaction; these negative expectations are repetitive, unintended, and uncontrollable (Haaga, D. A. F., Dyck, M. J., & Ernst, D.
