Beck's Theory of Depression

Beck's cognitive theory of depression suggests that depression is as a result of negative thoughts and views of the world. This can be overcome using cognitive therapy.

Cognitive theories of depression

  • Cognitive theories of depression take the view that depression is triggered by negative thoughts, interpretations, self-evaluations and expectations.
  • These dual-risk models propose that depression is triggered by a “cognitive vulnerability” (negative and maladaptive thinking) and by precipitating stressful life events.

Beck's theory

  • Psychiatrist Aaron Beck's cognitive theory of depression is one of the most well-known.
  • Beck theorised that depression-prone people possess depressive schemas.
  • Depressive schemas prompt dysfunctional and pessimistic thoughts about the self, the world, and the future.
  • It is likely that they develop early in childhood in response to adverse experiences, then remain dormant until they are activated by stressful or negative life events.

Cognitive biases

  • Beck believed that a dysfunctional style of thinking is maintained by cognitive biases, or errors in how we process information about ourselves.
  • This lead us to focus on negative aspects of experiences, interpret things negatively, and block positive memories.

Beck's negative triad

  • Beck's negative triad relates to the negative schemas and cognitive biases that lead to depressive thoughts.
  • The theory suggests that negative views about the self, the world and the future all lead into a downward spiral and cause a person to think depressive thoughts.

Cognitive therapy

  • Cognitive therapy is a form of psychotherapy that focuses on how a person’s thoughts lead to feelings of distress. It was developed as an expansion of Beck's theory.
  • The idea behind cognitive therapy is that how you think determines how you feel and act.
  • Cognitive therapists help their clients change dysfunctional thoughts to relieve distress.
  • They help a client see how they misinterpret a situation (cognitive distortion) and how to view situations in a more positive light.

Cognitive Approach to Treating Depression

Ellis’ ABC model is a technique used within cognitive behavioural therapy (CBT). It aims to alter a person’s problematic beliefs, so that events have different consequences.

Cognitive therapy

  • There are various types of cognitive therapy, all of which try to change negative beliefs or negative patterns of thinking.
  • Some use behavioural techniques, too.
  • The best known cognitive therapy is CBT - cognitive behavioural therapy.

Ellis' ABC model

  • Albert Ellis developed an ABC model that can be used in therapy. ABC stands for:
    • Activating event - this is the thing that causes the thoughts and feelings
    • Belief - this is the person’s thoughts about the activating event (how they interpret it). In the depressed person, the belief may be irrational.
    • Consequences - in terms of emotions and actions.

Example of ABC

  • For example, someone might not receive a reply to a text message (activating event), assume that their friend no longer likes them (irrational belief), and then feel very upset and delete that person from their social media account (consequences - emotions and actions).

Cognitive therapists

  • Cognitive therapists think that if a depressed person’s beliefs are changed, they will start to interpret events more realistically, resulting in healthier (though not always positive) emotions and more proportionate responses to events.

Evaluation of CBT

  • Strengths
    • Allows the client to take control – builds self-esteem.
    • Less reliance on drugs than other methods.
    • Does work for many people - Ellis (1957) claimed a 90% success rate for REBT, taking an average of 27 sessions to complete the treatment.
  • Limitations
    • Requires Individual motivation.
    • Relies on the competence of the therapist.
    • Works best combined with drugs.
    • Can be expensive and difficult to access (long waiting lists on NHS).

Evaluation of the cognitive approach

  • Strengths
    • It has practical applications. CBT is a successful therapy which challenges irrational beliefs.
  • Beck’s Depression Inventory and Hollon & Kendall’s Automatic Thought Questionnare (ATQ) are effective tools for diagnosing depression.
  • Limitations
    • Some types of depression occur with no activating event - reactive depression.
    • Ignores biochemical explanations for depression.
    • Not all patients are able to engage with CBT or find it useful.

Harrell and Ryon (1983) - Study Using the ATQ

Research aim: to evaluate the effectiveness of Hollon and Kendall’s Automatic Thoughts Questionnaire (ATQ) - a questionnaire designed to identify and measure the occurrence of automatic negative thoughts in depressed patients.

Procedure, results & conclusion

  • Procedure
    • 21 patients with depressions aged between 21-53 were compared with 40 people who did not have depression.
  • Results
    • The ATQ scores correlated highly with therapists scores on depression in individuals. It also compared well to other measures of depression such as the Beck depression inventory.
  • Conclusion
    • The ATQ-30 appears to be a valid and reliable measure of depression-related cognitions in clinical as well as nonclinical populations.

Evaluation

  • Strengths
    • Practical applications for diagnosing depression.
  • Limitations
    • Individual differences in experience and competence of clinicians administrating the test.
