Depression Flashcards
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.
Emotional π’ Characteristics
- Depressed Mood ππ» - a key characteristic is the ever present and overwhelming feelings of sadness π/ 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 π€ β 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 π€₯ and or inappropriate feelings of guilt πΊ
Cognitive π€ Characteristics
- Reduced Concentrationβ π€‘ 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 π€₯ β those suffering from depression often experience persistent negative beliefs about themselves and their abilities.
- Suicidal πͺ Thoughts π β depressives can have constant thoughts of death π and/or suicide.
Behavioural πͺπΌ Characteristics
- Change in Activity β typically depressed people have reduced amounts of energy resulting in fatigue π΄, lethargy and high levels of inactivity. In some cases depression can lead to the opposite effect β known as psychomotor agitation - agitated individuals struggle to relax and may end up pacing up and down.
- Change in Eating π and Sleeping π€ Patterns β 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 β there can be reduced levels of social interaction with friends and relations. π«
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:
- The self π€₯ β where individuals see themselves as being helpless, worthless and inadequate, e.g. βI am unattractive π€₯, what is there to like in me?β
- The world π(life experiences) β where obstacles are perceived within ones environment that cannot be dealt with, e.g. βI can understand why people do not like me, even my boyfriend ππ«left me.β
- The future π€ β where personal worthlessness is seen as blocking any improvements, e.g. βI am always going to be on my own and nothing will change itβ
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. βI am too stupid to pass examsβ
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.
- CBT begins with an assessment π in which the client and the cognitive behavioural therapist work together to identify the negative ππΌ or irrational thoughts π that will benefit from challenge. They jointly identify goals for the therapy and put together a plan πΊ to achieve them.
- CBT then involves working to change the negative and irrational thoughts. During this phase the therapist uses questioning βdesigned to challenge maladaptive thoughts. The client may be taught skills such as relaxation π techniques e.g. guided imagery and positive self statements with a view to over the time these challenges will result in a personβs 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.
