Cognitive approach to depression

Introduction to the Cognitive Approach to Depression

Welcome to one of the most practical and influential areas of Psychology! In the previous chapter, we looked at the characteristics of depression (how it feels, looks, and affects behavior). Now, we are diving into the Cognitive Approach. This approach is based on a simple but powerful idea: our thoughts (cognitions) cause our feelings and behaviors.

If you think in a negative or "faulty" way, you are more likely to experience the symptoms of depression. We will look at two famous theories by Beck and Ellis, and then explore how psychologists use these ideas to treat depression through Cognitive Behaviour Therapy (CBT).

1. Explaining Depression: Beck’s Cognitive Theory

Aaron Beck (1967) suggested that some people are more vulnerable to depression because they develop a "faulty" way of processing information. He identified three parts to this cognitive vulnerability:

A. Faulty Information Processing

When depressed, people tend to focus on the negative aspects of a situation and ignore the positives. For example, if a student gets 95% on a test but gets one question wrong, they might obsess over that one mistake rather than celebrating their success. They "blow small problems out of proportion."

B. Negative Self-Schemas

A schema is a "mental package" of ideas and information developed through experience. They act as a mental shortcut for interpreting the world. A self-schema is the information we have about ourselves. If you have a negative self-schema, you interpret all information about yourself in a negative way.

C. The Negative Triad

Beck proposed that depressed people have a "negative triad" of thoughts that occur automatically. Think of this as a cycle of gloom that traps the individual:

• Negative view of the World: "The world is a cold, hard place where nothing goes right."
• Negative view of the Future: "Things will never get better; I will always be a failure."
• Negative view of the Self: "I am worthless and unlovable."

Quick Tip: To remember the triad, think of the "WFS" (World, Future, Self). It’s like wearing dark-tinted glasses that make every part of life look grey.

2. Explaining Depression: Ellis’s ABC Model

Albert Ellis (1962) had a slightly different take. He argued that good mental health is the result of rational thinking, while depression results from irrational thoughts. He used the ABC Model to explain how this happens:

• A - Activating Event: We experience a negative event (e.g., failing an exam or being ghosted by a friend).
• B - Beliefs: This is the most important part! It’s how we interpret the event. This can be rational ("That’s a shame, I'll try harder next time") or irrational ("I am a total loser and everyone hates me").
• C - Consequences: The emotional and behavioral result. Irrational beliefs lead to unhealthy consequences, like depression.

Example: If you lose your job (A), and you believe you are useless and will never work again (B), the consequence (C) is a feeling of deep despair and giving up on job hunting.

Key Takeaway: For Ellis, it isn't the event itself that causes depression, but our irrational belief about that event.

3. Treating Depression: Cognitive Behaviour Therapy (CBT)

CBT is the most commonly used psychological treatment for depression. It is a collaborative effort between the therapist and the patient to identify and challenge irrational or negative thoughts.

Beck’s Cognitive Therapy

The goal is to identify negative thoughts about the Negative Triad (World, Future, Self) and challenge them directly.
"Patient as Scientist": Patients are encouraged to test the reality of their negative beliefs. If a patient says, "Everyone hates me," the therapist might give them "homework" to record every time someone is nice to them. In the next session, they use this evidence to prove the patient's thought was incorrect.

Ellis’s REBT (Rational Emotive Behavior Therapy)

Ellis extended his ABC model to ABCDE for therapy:

• D - Dispute: The therapist challenges (disputes) the patient's irrational beliefs.
• E - Effect: The goal is to replace the irrational belief with a more rational, effective one.

Therapists might use Empirical Disputing (asking for evidence: "Where is the proof that your belief is true?") or Logical Disputing (asking if the thought makes sense: "Does it follow logically that failing one test means you are a failure at everything?").

Behavioral Activation

Alongside the "thought work," CBT also encourages patients to be more active. Depressed people often stop doing things they enjoy. The therapist works with them to decrease avoidance and isolation by engaging in activities that improve their mood.

4. Evaluating the Cognitive Approach

In AQA Psychology, evaluating (AO3) is vital. Here are the strengths and limitations you need to know:

Strengths (+)

• It is highly effective: Research shows that CBT is just as effective as antidepressant medication for many people, and it has a lower relapse rate because it gives the patient tools to use in the future.
• It empowers the patient: Unlike drug therapy, CBT gives the patient an active role in their own recovery. They learn to manage their own thoughts.
• Practical Application: Beck’s triad and Ellis’s model have led to treatments that have helped millions of people worldwide.

Limitations (-)

• Cognitive Primacy: The approach assumes that thoughts cause emotions. However, some critics argue it could be the other way around—the depression (biological) causes the negative thoughts.
• Motivation: A major symptom of depression is a lack of motivation. Some patients may be too depressed to engage with the "homework" and hard work required for CBT.
• Ignores Biology: The approach overlooks genetic or neurochemical factors. For instance, low levels of serotonin are linked to depression, but CBT ignores this purely biological side.
• Focus on the "Here and Now": CBT focuses on current thoughts. Some patients may find it frustrating that the therapy doesn't explore past traumas or childhood experiences that might be the root cause of their depression.

Quick Review: Check Your Progress

1. Who proposed the "Negative Triad"? (Answer: Beck)

2. In Ellis's ABC model, what does the "B" stand for? (Answer: Beliefs)

3. What is the "Patient as Scientist" technique? (Answer: Setting homework to gather evidence to disprove negative thoughts).

4. What percentage of marks in your exam involve mathematical skills? According to the syllabus, at least \(10\%\) of the marks will test your math skills, such as calculating the mean or interpreting percentages in clinical trials.

Common Mistake to Avoid: Don't confuse Beck and Ellis! Remember: Beck = Triad (Self/World/Future) and Ellis = ABC (Activating event/Beliefs/Consequences).
