Depression Flashcards
What is Depression ๐๐ป?
Depression ๐๐ป is a mood disorder characterised by extreme sadness ๐.
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.
Emotional ๐ข Characteristics
- Depressed Mood ๐๐ป - a key characteristic is the ever present and overwhelming feelings of sadness ๐/ hopelessness. Lowered mood is a defining emotional element of depression but it is more intense and pronounced than in the daily kind of experience people in general can have.
- Loss of Interest and Pleasure ๐ค โ depression is often characterised by a lack of enthusiasm associated with a lack of concern or pleasure in daily activities.
- Worthlessness - those suffering from depression often have constant feelings of low self-worth ๐คฅ and or inappropriate feelings of guilt ๐บ
Cognitive ๐ค Characteristics
- Reduced Concentrationโ ๐คก difficulty in paying and maintaining concentration and/or slowed down thinking and difficulty making decisions. Poor concentration and poor decision making are likely to interfere with the individuals work.
- Negative Beliefs about Self ๐คฅ โ those suffering from depression often experience persistent negative beliefs about themselves and their abilities.
- Suicidal ๐ช Thoughts ๐ญ โ depressives can have constant thoughts of death ๐ and/or suicide.
Behavioural ๐ช๐ผ Characteristics
- Change in Activity โ typically depressed people have reduced amounts of energy resulting in fatigue ๐ด, lethargy and high levels of inactivity. In some cases depression can lead to the opposite effect โ known as psychomotor agitation - agitated individuals struggle to relax and may end up pacing up and down.
- Change in Eating ๐ and Sleeping ๐ค Patterns โ people may experience a change in appetites which may mean they eat more or less than usual, and have significant weight changes (5%) either gaining or losing weight. Insomnia or excessive sleeping are characteristics of depression. The key point is that eating and sleeping behaviours are disrupted by depression.
- Social Impairment โ there can be reduced levels of social interaction with friends and relations. ๐ซ
The Cognitive Approach to Explaining Depression ๐๐ป
The cognitive approach generally explains depression ๐๐ป in terms of faulty and irrational thought ๐ญ processes and perceptions.
Becks Negative Triad 1๏ธโฃ9๏ธโฃ6๏ธโฃ7๏ธโฃ
Aaron Beck believed depression ๐๐ปis caused by negative ๐๐ผ thinking ๐ญ , especially about oneself and that negative ๐๐ผ thinking ๐ญ comes before the development of depression ๐.
Negative ๐๐ผ cognitive triad โ Beck believed that depression ๐ has three components called the cognitive triad; which is a negative ๐๐ผ view of the self ๐คฅ, the world ๐ and the future ๐ค . Beck believed that these negative ๐๐ผ views interfere with normal cognitive processing, such as memory and problem-solving. Each one feeds into the other. For example:
- The self ๐คฅ โ where individuals see themselves as being helpless, worthless and inadequate, e.g. โI am unattractive ๐คฅ, what is there to like in me?โ
- The world ๐(life experiences) โ where obstacles are perceived within ones environment that cannot be dealt with, e.g. โI can understand why people do not like me, even my boyfriend ๐๐ซleft me.โ
- The future ๐ค โ where personal worthlessness is seen as blocking any improvements, e.g. โI am always going to be on my own and nothing will change itโ
โข Negative ๐๐ผ self schemas
Beck believes that depressed ๐๐ปpeople develop negative ๐๐ผ schemas about themselves, which makes them think in this negative ๐๐ผ way.
Negative ๐๐ผschemas develop in childhood ๐ง๐ปand adolescence ๐ฉ๐ผ as a result of rejection ๐ by parents or friends in the form of criticism and exclusion, or perhaps by the loss of a close family member โฐ๏ธ.
Such negative ๐๐ผ events mould the personโs concept of themselves as unwanted or unloved ๐.
This then filters into adulthood ๐ฉ๐ผ providing a negative ๐๐ผ framework ๐ผ to view life in a pessimistic fashion. Negative ๐๐ผ schemas lead to systematic cognitive biases in thinking.
โข Cognitive ๐ค biases
People with negative ๐๐ผ schemas become prone to making errors โ in their thinking ๐ญ . 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 1๏ธโฃ9๏ธโฃ5๏ธโฃ7๏ธโฃ - IRRATIONAL THINKING
Albert Ellis believed that depressives ๐๐ป 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 ๐ 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 ๐โ
B is the BELIEF which is held about the event which may be rational or irrational
Belief about why this happened
E.g. โI am too stupid to pass examsโ
C is the CONSEQUENCEโ rational beliefs lead to healthy emotions whereas irrational beliefs lead to unhealthy emotions.
Consequences of Belief.
E.g. Leave college and become depressed ๐๐ป
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 depression๐๐ป. Individuals who become depressed ๐๐ป interpret unpleasant events in excessively negative or threatening ways at point B.
What are the evaluation points for the Cognitive Explanation of Depression ๐๐ป
1) Supporting research โ
2) Cause or effect โ๏ธ
3) Practical application โ
4) A more holistic approach is needed โ๏ธ
Outline the evaluation point
1) Supporting research โ
Becks Negative Triad
Point:
There is a wealth of research ๐ฌ to support Beckโs cognitive explanation.
Evidence:
Koster et alโs study used student ๐จ๐ผโ๐ volunteers who took part in an attention task and were presented with positive โ, negativeโ and neutral words.
Explain:
They found ๐ that depressed ๐๐ป participants spent longer attending to the negative words than the non-depressed group.
Re-cap:
The result supports โ
the aspect of cognitive biases and that people with depression ๐๐ปattend to negative โ 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 peopleโs everyday experiences of negative thinking; therefore, lacking ecological validity. Also, the study was conducted using college ๐จ๐ผโ๐ students, which makes it difficult to apply the findings to actual clinically depressed ๐๐ป patients.
Ellis ABC model
Point:
The view that depression ๐๐ป is linked to irrational thinking is supported by research.
Example:
Hammen and Krantz (76) found that depressed๐๐ป participants made more errors โin 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 ๐๐ป(Benjamin 2011).
Outline the evaluation point
2) Cause or effect โ๏ธ
Point:
It is difficult to determine the extent to which negative cognitive patternโs cause depression ๐๐ป.
Explain:
Numerous studies have shown that depressed ๐๐ปpeople do show more negative ๐๐ผ thinking than controls.
Example:
For example, Evans used a questionnaire of pregnant ๐คฐ๐ป women and found that women with a high negative ๐๐ผ 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 ๐๐ผ 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 โ
Point:
Both Ellisโ ABC model and Beckโs cognitive explanation of depression ๐๐ป has been very influential and has stimulated a huge amount of research ๐ฌ 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 ๐๐ป.
Example:
Beck reviewed the effectiveness of CBT and found it highly effective in treating depression ๐๐ปespecially unipolar depressive๐๐ป disorder.
Elaborate:
Lipskyโs research ๐ฌ found that by challenging a personโs irrational negative ๐๐ผ beliefs, depression ๐๐ปcan be reduced.
Re-cap:
This evidence concerning the effectiveness of both Ellisโ and Beckโs forms of CBT can be taken as support for the theory itโs based on.
Outline the evaluation point
4) A more holistic approach is needed โ๏ธ
Point:
It has been argued that the cognitive distortions of depressed ๐๐ปpeople 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 ๐ง๐ป๐ฆ๐ผ(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 ๐ฌ supports โ
the role of low levels of serotonin in depressed people and the success of drug therapies ๐ 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 ๐ฏ to identify ๐ 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 patientโs irrational thoughts is of crucial importance if recovery from depression๐๐ป is to occur.
- CBT begins with an assessment ๐ in which the client and the cognitive behavioural therapist work together to identify the negative ๐๐ผ or irrational thoughts ๐ญ that will benefit from challenge. They jointly identify goals for the therapy and put together a plan ๐บ to achieve them.
- CBT then involves working to change the negative and irrational thoughts. During this phase the therapist uses questioning โdesigned to challenge maladaptive thoughts. The client may be taught skills such as relaxation ๐ techniques e.g. guided imagery and positive self statements with a view to over the time these challenges will result in a personโs cognition changing.
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:
- Thought ๐ญ catching ๐๐ผ
- Cognitive ๐ค Reconstructing ๐๐
- Behavioural ๐๐ปโโ๏ธactivation
- Homework ๐(patient ๐ฉ๐ผ as scientist๐ฉ๐ผโ๐ฌ)
What is meant by THOUGHT ๐ญ CATCHING ๐๐ผ?
Identifying ๐ negative ๐๐ผ thoughts.
Individuals are taught to see the link between their thoughts and how they feel.
They might, as part of their homework ๐assignments, be asked to record ๐ฅ any emotion-arousing events and also the automatic negative ๐๐ผ thoughts that are associated with these events (cognitive element).
What is meant by COGNITIVE ๐คRECONSTRUCTING๐๐?
Clients ๐ฉ๐ผโ๐ผare asked to challenge these dysfunctional thoughts and replace them with more constructive ones.
This cognitive reconstructing can lead to individual to have more positive ๐thoughts and can alleviate the depressive symptoms (cognitive element).
What is meant by BEHAVIOURAL ๐๐ปโโ๏ธ 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 ๐ฉ๐ผโ๐ผand therapist ๐ฉ๐ปโ๐ซ identify ๐ potentially pleasurable activities and to overcome any obstacles in carrying them out.
They are given graded homework ๐ assignments which allow them to experiment with the chosen activity, and the engage in progressively more rewarding activities.
What is meant by HOMEWORK ๐ (patient as scientist) ?
Patients ๐ฉ๐ผโ๐ผ are often set homework ๐ 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 โ
2) Competence Of Therapist ๐ฉ๐ปโ๐ซ(not very good @ it) โ๏ธ
Outline the evaluation point
1) Support for the effectiveness of CBT โ in terms of CBTโs 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 ๐๐ป.
Example:
March 2๏ธโฃ0๏ธโฃ0๏ธโฃ7๏ธโฃcompared effects of CBT, with anti-depressant drugs ๐ 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 ๐ depression ๐๐ป.
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 ๐ฉ๐ปโ๐ซ(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 ๐ฉ๐ปโ๐ซ.
Explain:
Appears to explain a significant amount of variation in CBT outcomes
Example:
Kuyken 2๏ธโฃ0๏ธโฃ0๏ธโฃ9๏ธโฃsupports this claim, concluding that as much as 15% is variance in outcome may be attributed to therapist competence.
Elaborate:
They found that therapists ๐ฉ๐ปโ๐ซ 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 ๐ฉ๐ปโ๐ซ.
