The cognitive approach to explaining depression focuses on faulty and irrational thought processes and perceptions.
According to Aaron Beck, depression is caused by negative thinking, especially about oneself, and this negative thinking precedes the development of depression.
Albert Ellis's ABC Model (1957) states that depressives mistakenly blame external events for their unhappiness, but it is their interpretation of these events that is to blame for their distress.
Depression is explained through the negative cognitive triad, consisting of a negative view of the self, the world, and the future
These negative views interfere with normal cognitive processing like memory and problem-solving, with each component feeding into the other
Examples include negative views of the self (helpless, worthless, inadequate), the world (perceiving obstacles that cannot be overcome), and the future (feeling personal worthlessness blocks any improvements)
Depressed individuals develop negative schemas about themselves.
These negative schemas develop in childhood and adolescence due to rejection by parents or friends, criticism, exclusion, or loss of a close family member.
Negative events shape the person's self-concept as unwanted or unloved, carrying into adulthood and providing a negative framework for viewing life pessimistically.
People with negative schemas are prone to making thinking errors and cognitive biases
They selectively focus on certain aspects of a situation and ignore equally relevant information
One example is overgeneralization, where individuals with depression make sweeping conclusions based on a single event (e.g., assuming someone hates them because they did not smile)
