What is Depression ππ»?
Depression ππ» is a mood disorder characterised by extreme sadness π.
To be diagnosed with major depression, the DSM5 states an individual must experience at least 5 from a list of symptoms including; one of depressed mood and/or loss of interest or pleasure in most activities, nearly every day for at least two weeks.

The Cognitive Approach to Explaining Depression ππ»
The cognitive approach generally explains depression ππ» in terms of faulty and irrational thought π processes and perceptions.
Becks Negative Triad 1οΈβ£9οΈβ£6οΈβ£7οΈβ£
Aaron Beck believed depression ππ»is caused by negative ππΌ thinking π , especially about oneself and that negative ππΌ thinking π comes before the development of depression π.
Negative ππΌ cognitive triad β Beck believed that depression π has three components called the cognitive triad; which is a negative ππΌ view of the self π€₯, the world π and the future π€ . Beck believed that these negative ππΌ views interfere with normal cognitive processing, such as memory and problem-solving. Each one feeds into the other. For example:
β’ Negative ππΌ self schemas
Beck believes that depressed ππ»people develop negative ππΌ schemas about themselves, which makes them think in this negative ππΌ way.
Negative ππΌschemas develop in childhood π§π»and adolescence π©πΌ as a result of rejection π by parents or friends in the form of criticism and exclusion, or perhaps by the loss of a close family member β°οΈ.
Such negative ππΌ events mould the personβs concept of themselves as unwanted or unloved π.
This then filters into adulthood π©πΌ providing a negative ππΌ framework πΌ to view life in a pessimistic fashion. Negative ππΌ schemas lead to systematic cognitive biases in thinking.
β’ Cognitive π€ biases
People with negative ππΌ schemas become prone to making errors β in their thinking π . They tend to focus selectively on certain aspects of a situation and ignore equally relevant information known as cognitive biases.
One example is over generalisation where people with depression make a sweeping conclusion on the basis of a single event (e.g. he did not smile at me so he must hate me).
Ellis ABC Model 1οΈβ£9οΈβ£5οΈβ£7οΈβ£ - IRRATIONAL THINKING
Albert Ellis believed that depressives ππ» mistakenly blame external events for their unhappiness however it is their interpretation of these events that is to blame for their distress. He proposed that the key π to depression lay in irrational beliefs. According to this model, depression is produced by the irrational thoughts triggered by unpleasant events. In his ABC model:
A refers to an ACTIVATING EVENT:
something happens in the environment around you E.g. failing exam πβ
B is the BELIEF which is held about the event which may be rational or irrational
Belief about why this happened
E.g. ‘I am too stupid to pass exams’
C is the CONSEQUENCEβ rational beliefs lead to healthy emotions whereas irrational beliefs lead to unhealthy emotions.
Consequences of Belief.
E.g. Leave college and become depressed ππ»
It is not the activating event that causes the consequence; the consequence is caused by the beliefs about the activating event. Having irrational beliefs leads to unhealthy negative reactions and emotions, which in turn can lead to depressionππ». Individuals who become depressed ππ» interpret unpleasant events in excessively negative or threatening ways at point B.
What are the evaluation points for the Cognitive Explanation of Depression ππ»
1) Supporting research β
2) Cause or effect βοΈ
3) Practical application β
4) A more holistic approach is needed βοΈ
Outline the evaluation point
1) Supporting research β
Becks Negative Triad
Point:
There is a wealth of research π¬ to support Beckβs cognitive explanation.
Evidence:
Koster et alβs study used student π¨πΌβπ volunteers who took part in an attention task and were presented with positive β, negativeβ and neutral words.
Explain:
They found π that depressed ππ» participants spent longer attending to the negative words than the non-depressed group.
Re-cap:
The result supports β
the aspect of cognitive biases and that people with depression ππ»attend to negative β aspects of their life rather than the positive.
Elaborate:
However, the study was carried out in artificial conditions and used a procedure quite different from peopleβs everyday experiences of negative thinking; therefore, lacking ecological validity. Also, the study was conducted using college π¨πΌβπ students, which makes it difficult to apply the findings to actual clinically depressed ππ» patients.
Ellis ABC model
Point:
The view that depression ππ» is linked to irrational thinking is supported by research.
Example:
Hammen and Krantz (76) found that depressedππ» participants made more errors βin logic when asked to interpret written material than non-depressed participants.
Re-cap:
Additionally, empirical support for Ellis therapy based on the ABC model contributes to the acceptance that irrational beliefs lead to depression ππ»(Benjamin 2011).
Outline the evaluation point
2) Cause or effect βοΈ
Point:
It is difficult to determine the extent to which negative cognitive patternβs cause depression ππ».
Explain:
Numerous studies have shown that depressed ππ»people do show more negative ππΌ thinking than controls.
Example:
For example, Evans used a questionnaire of pregnant π€°π» women and found that women with a high negative ππΌ schema were subsequently 60% more likely to become depressed than those with a low negative schema.
Elaborate:
However, as yet there is not enough convincing evidence that such thinking comes before a depressive episode.
Re-cap:
It seems likely that negative ππΌ thinking is a consequence of depression and that it might well serve to maintain the disorder rather than explain its origins.
Outline the evaluation point
3) Practical application β
Point:
Both Ellisβ ABC model and Beckβs cognitive explanation of depression ππ» has been very influential and has stimulated a huge amount of research π¬ into the disorder over the last few decades.
Explain:
They have contributed greatly to our understanding of depression and to the rise of cognitive behavioural therapies, which have been very helpful in alleviating the symptoms of depression ππ».
Example:
Beck reviewed the effectiveness of CBT and found it highly effective in treating depression ππ»especially unipolar depressiveππ» disorder.
Elaborate:
Lipskyβs research π¬ found that by challenging a personβs irrational negative ππΌ beliefs, depression ππ»can be reduced.
Re-cap:
This evidence concerning the effectiveness of both Ellisβ and Beckβs forms of CBT can be taken as support for the theory itβs based on.
Outline the evaluation point
4) A more holistic approach is needed βοΈ
Point:
It has been argued that the cognitive distortions of depressed ππ»people are not a cause but a symptom of the depression therefore other explanations are needed to fully understand the disorder and where faulty thoughts originated from.
Example:
Psychodynamic π§π»π¦πΌ(childhood events) explanations could play role in helping to understand how early experiences have influenced the development of the irrational and faulty thinking characteristic of depression.
Explain:
Additionally current research π¬ supports β
the role of low levels of serotonin in depressed people and the success of drug therapies π for treating depression offer further strength to a biological explanation.
Elaborate:
Taking electic approach, including social, biological and psychological theories, would be a better way of explaining such a complex disorder.
Re-cap:
To fully understand depression more holistic approach is therefore needed.
The Cognitive Approach to Treating Depression
The therapy aims target π― to identify π and alter negative and irrational beliefs and expectations (cognitive element) and to alter dysfunctional behaviours that may be contributing to the depression (behavioural element). It is assumed as part of CBT that successfully challenging the patientβs irrational thoughts is of crucial importance if recovery from depressionππ» is to occur.
The therapy is Intended to be relatively brief consisting of 20 sessions over 16 weeks.
It is an active, directive therapy which focuses on current problems and current dysfunctional thinking. Some CBT therapists use techniques purely from Becks and some from Ellis. Most draw on both when treating depression.
What are the strategies used within CBT for people with depression?
Strategies used within CBT for people with depression include:
What is meant by THOUGHT π CATCHING ππΌ?
Identifying π negative ππΌ thoughts.
Individuals are taught to see the link between their thoughts and how they feel.
They might, as part of their homework πassignments, be asked to record π₯ any emotion-arousing events and also the automatic negative ππΌ thoughts that are associated with these events (cognitive element).
What is meant by COGNITIVE π€RECONSTRUCTINGππ?
Clients π©πΌβπΌare asked to challenge these dysfunctional thoughts and replace them with more constructive ones.
This cognitive reconstructing can lead to individual to have more positive πthoughts and can alleviate the depressive symptoms (cognitive element).
What is meant by BEHAVIOURAL ππ»ββοΈ ACTIVATION (behavioural element)?
A characteristic of many depressed people is that they no longer participate in activities that they previously enjoyed.
During CBT and REBT, the client π©πΌβπΌand therapist π©π»βπ« identify π potentially pleasurable activities and to overcome any obstacles in carrying them out.
They are given graded homework π assignments which allow them to experiment with the chosen activity, and the engage in progressively more rewarding activities.
What is meant by HOMEWORK π (patient as scientist) ?
Patients π©πΌβπΌ are often set homework π tasks encouraging them to test reality of their irrational beliefs to help put new rational beliefs into practise.
What are the evaluation points of CBT in terms of its EFFECTIVENESS
1) Support for the effectiveness of CBT β
2) Competence Of Therapist π©π»βπ«(not very good @ it) βοΈ
Outline the evaluation point
1) Support for the effectiveness of CBT β in terms of CBTβs EFFECTIVENESS
Point:
There have been numerous studies that have shown CBT is defective in reducing symptoms of moderate and severe depression and in preventing relapse - especially for those who only have depression ππ».
Example:
March 2οΈβ£0οΈβ£0οΈβ£7οΈβ£compared effects of CBT, with anti-depressant drugs π and a combination of 2 in 327 adolescents with a main diagnosis of depression.
After 36 weeks 81% of the CBT group and 81% of antidepressant group and 86% of the combined group were significantly improved.
Elaborate:
The high % in CBT group suggests that CBT is very effective in eating π depression ππ».
Re-cap:
However, also suggests that it may be even more effective when used as a combined treatment alongside medication.
Outline the evaluation point
2) Competence Of Therapist π©π»βπ«(not very good @ it)
Competence - knowledge, skills and attitudes and their integration that allow individuality perform.
Point:
Issue with assessing the effectiveness of CBT is the competence of the therapist π©π»βπ«.
Explain:
Appears to explain a significant amount of variation in CBT outcomes
Example:
Kuyken 2οΈβ£0οΈβ£0οΈβ£9οΈβ£supports this claim, concluding that as much as 15% is variance in outcome may be attributed to therapist competence.
Elaborate:
They found that therapists π©π»βπ« who were assessed as most competent had better patient outcomes regardless of the complexity of the case.
Re-cap:
Appears that to some extent, effectiveness of CBT depends upon the training and skills of the therapist π©π»βπ«.
