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.
Beck's Negative Triad:
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)
Negative schemas:
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.
Cognitive biases:
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)
In the ABC model, A refers to an activating event: something that happens in the environment.
B in the ABC model is the belief held about the event, which can be rational or irrational.
C in the ABC model stands for the consequence: rational beliefs lead to healthy emotions, while irrational beliefs lead to unhealthy emotions
Supporting research for Beck's cognitive explanation of depression:
Koster et al's study used student volunteers in an attention task with positive, negative, and neutral words
Depressed participants spent longer attending to negative words than non-depressed individuals.
Supports the idea of cognitive biases in depression where individuals focus on negative aspects of life.
Empirical support for Ellis's therapy based on the ABC model contributes to the acceptance that irrational beliefs lead to depression (Benjamin 2011).
Cause or effect of distorted cognitive patterns in depression:
Difficult to determine if distorted cognitive patterns cause depression
Depressed individuals show more negative thinking than controls in numerous studies
Negative thinking may be a consequence of depression rather than its cause
Negative thinking might serve to maintain the disorder rather than explain its origins
Practical application of Ellis' ABC model and Beck's cognitive explanation of depression:
Influential in stimulating research into depression and cognitive behavioural therapies
Contributed greatly to understanding depression and rise of cognitive behavioural therapies
CBT found highly effective in treating depression, especially unipolar depressive disorder
Challenging irrational negative beliefs can reduce depression (Lipsky's research)
Argument for a more holistic approach to understanding depression:
Cognitive distortions in depressed individuals may be a symptom rather than a cause of depression
Other explanations, like psychodynamic explanations, are needed to fully understand the disorder
Role of low serotonin levels and success of drug therapies offer strength to a biological explanation
A holistic approach is necessary for a comprehensive understanding of depression
