Cognitive Models of Depression and Schemas

Cognitive Models of Depression

• Aaron T. Beck is credited with developing one of the first cognitive models of depression.

Beck's Cognitive Model of Depression

• Beck observed that depressed clients made negatively biased statements, including all-or-nothing thinking, overgeneralization, and selective abstraction.
• Schemas are central to Beck's cognitive model of depression, and are proposed to account for the enduring aspects of emotional disorders like depression.
• A schema is a mental framework that organizes information and influences an individual's perception of the world.
• The central role of schemas is to distort and bias an individual's perception of reality, leading to negative emotions and behaviors.
• Schemas develop over time through experiences, especially in childhood, and can be triggered by stressful events.

Schemas and Depression

• Intermediary beliefs are rules or assumptions that guide an individual's behavior and are based on their core beliefs.
• Core beliefs are absolute, rigid, and extreme beliefs that are deeply ingrained in an individual's schema.
• Conditional rules are "if-then" statements that link an individual's core beliefs to their intermediary beliefs.

Automatic Thoughts in Depression

• Automatic thoughts are negative, spontaneous, and uncensored thoughts that arise in response to a situation or stimulus.
• Depressed individuals tend to have negative automatic thoughts, which tend to be absolute, categorical, and unconditional.
• A typical negative automatic thought might be "I'm not important" or "I'm not loved" in response to a situation like being ignored by a friend.

Cognitive Errors in Depression

• The thinking of individuals with depression is characterized by cognitive errors, including all-or-nothing thinking, overgeneralization, selective abstraction, arbitrary inference, personalization, and dichotomous thinking.
• Selective abstraction involves focusing on one aspect of a situation and ignoring other important aspects.
• Personalization involves attributing negative events to oneself or one's own characteristics.
• Arbitrary inference involves making conclusions without sufficient evidence.
• Dichotomous thinking involves categorizing experiences into absolute good or bad categories.
• Overgeneralization involves making sweeping conclusions based on a single event or experience.

Cognitive-Behavioral Therapy (CBT) for Depression

• CBT is considered one of the most well-researched treatments for depression.
• The aim of the cognitive component in CBT for depression is to identify and challenge negative automatic thoughts and schemas.
• Meta-analytic findings suggest that CBT is as effective as medication for depression, and may be more effective in the long term.

Challenging Core Beliefs

• A key step in identifying a core belief is to explore the evidence for and against the belief.
• The purpose of identifying a core belief is to challenge and modify it in order to reduce symptoms of depression.
• Challenging core beliefs through behavioral experiments can be a more powerful way to change them.

Behavioral Activation for Depression

• One of the key beliefs in behavioral activation for depression is that changes in behavior can lead to changes in mood and cognitive functioning.
• The main goal of behavioral activation is to increase the individual's engagement in pleasurable activities and to reduce avoidance behaviors.
• Behavioral activation is as effective as CBT for depression, and may be more effective in some cases.
