Insomnia - reduced sleep and waking early
Hypersomnia - increased need for sleep
Increase in appetite
Decrease in appetite

Emotional Characteristics of Depression
Loweredmood - feeling empty and worthless
Anger
Loweredself esteem - self loathing and hating yourself
Cognitive Characteristics of Depression
Poorconcentration - unable to stick to tasks, hard to make decisions that would be easy and interference with work

What are the 2cognitiveexplanations of depression
Beck'scognitivetheory
Ellis'sABCModel
What are the 3parts of Beck'scognitivetheory?
Faulty information processing
Negativeselfschema
Negativetriad
What is faultyinformationprocessing?
Only think of the negative aspects of a situation and ignore the positives
Depressed people think in 'black and white' thinking all is good or bad
What is a negative self schema?
A schema is a ‘package’ of ideas and information developed through experience
A self-schema is the package of information people have about themselves
Negative self-schema - interpret all information about themselves in a negative way
What is the negative triad?
A person develops depression because of three types of negative thinking: negative thoughts about the world, the future and oneself
Examples of the negative triad
Negative view of the world – ‘the world is a cold hard place’ creating the impression that there is no hope anywhere
Negative view of the future – ‘there isn’t much chance that the economy will really get better’ reduces any hopefulness and enhances depression
Negative view of the self – ‘I am a failure’ enhance any existing depressive feelings and confirm the existing emotions of low self-este
What are the 3 parts of the ABC model?
ActivatingEvent
Beliefs
Consequences
ABC Model
Activating event - irrational thoughts are triggered by external events e.g failing an important test or ending a relationship
Beliefs - Range of irrational beliefs: achieveperfection, ‘I-can’t-stand-it-itis’ and utopianism
Consequences - an activating event triggers irrational beliefs there are emotional and behavioural consequences e.g if a person believes that they must always succeed and then fails at something this can trigger depression
What are the 3types of irrationalbeliefs
Must always succeed or achieveperfection
‘I-can’t-stand-it-itis’ is the belief that it is a major disaster whenever something does not go smoothly
Utopianism is the belief that life is always meant to be fair
Beck's Cognitive Theory AO3: Research Support
‘Cognitivevulnerabilities' - ways of thinking that may lead to peoplebecomingdepressed e.g faulty information processing, negative self-schema and cognitive triad
Researchers concluded that not only were these cognitivevulnerabilitiesmorecommon in depressedpeople but they precededdepression
In a more recent study 473adolescents had their cognitivevulnerability measured and found that showing cognitivevulnerabilitypredictedlaterdepression showing that there is an association between cognitivevulnerability and depression
Beck's Cognitive Theory AO3: Real World Application
Assessing cognitive vulnerability allows psychologists to screenyoungpeople, identifying those most at risk of developing depression in the future and monitoring them
Understanding cognitive vulnerability can also be applied in cognitive behavioural therapy (CBT)
Work by altering the kind of cognitions that make people vulnerable to depression, making them more resilient to negative life events
This means that an understanding of cognitive vulnerability is useful in more than one aspect of clinical practice
Beck's CognitiveTheory AO3: PartialExplanation
Depressed people show particular patterns of cognition which can be seen before the onset of depression
It appears that Beck’s suggestion of cognitive vulnerabilities is at least a partial explanation for depression
However, there are some aspects to depression that are not particularly well explained by cognitive explanations.
Some depressed people feel extreme anger, and some experience hallucinations and delusions
Ellis's ABC Model AO3: RealWorldApplication
Ellis’s approach to cognitive therapy is called rational emotive behaviour therapy (REBT)
The idea of REBT is that by vigorously arguing with a depressed person the therapist can alter the irrational beliefs that are making them depressed
There is some evidence to support the idea that REBT can both change negative beliefs and relieve the symptoms of depression so REBT has value
Ellis's ABC Model AO3: Only explains one type of depression
Reactive depression is when depression is triggered by life events
Many cases of depression are not traceable to life events and it is not obvious what leads the person to become depressed
This type of depression is called endogenous depression - caused by biology
Ellis’s model can only explain some cases of depression and is therefore only a partial explanation
Ellis's ABC Model AO3: Ethical Issues
The ABC model of depression is controversial because it locates responsibility for depression purely with the depressed person
Critics say this is blaming the depressed person which would be unfair
But provided it is used appropriately and sensitively the application of the ABC model in REBT does appear to make at least some depressed people achieve more resilience and feel better
What is CognitiveBehaviouralTherapy?
Method for treating mental disorders based on both cognitive and behavioural technique
Assess the patient and work together to clarify the patient's problems
Identify where the negative or irrational thoughts are and put more effective behaviours in place
What is Beck's Cognitive Therapy?
To identify automatic thoughts about the world, the self and the future (negative triad) and once identified these thoughts must be challenged
Cognitive therapy aims to help clients test the reality of their negative beliefs
They might be told to record when they enjoyed an event then in future sessions if clients say there is no point in going to events the therapist has evidence and can prove that the client’s statements are incorrect
What is Ellis's Rational Emotive Behavioural Therapy?
REBT extends the ABC model to an ABCDE model – D stands for dispute and E for effect
The central technique of REBT is to identify and challenge irrational thoughts to break the link between negative life events and depression
A client might talk about how unlucky they have been or how unfair things seem and an REBT therapist would identify this as utopianism and challenge this as an irrational belief and this would involve a vigorous argument
Ellis identified different methods of disputing:
Logical , empirical and pragmatic
What is logicaldisputing?
Involves disputing whether the negative thought logically follows from the facts
What is empiricaldisputing?
Disputing whether there is actual evidence to support the negative belief
What is pragmaticdisputing?
Checking if the irrational belief is useful and practical in believing
What is BehaviouralActivation?
Patients are set tasks that encourage them to be more active and engage in more enjoyable activities
What is unconditionalpositiveregard?
Ellis realises clients need to realise their importance
If they felt worthless they were less likely to change their beliefs
If the therapist provides respect and appreciation they may be able to change their beliefs
CBT AO3: Evidence for effectiveness
One study compared CBT to antidepressant drugs and also to a combination of both treatments when treating 327 depressed adolescents
After 36 weeks, 81% of the CBT group, 81% of the antidepressants group and 86% of the CBT plus antidepressants group were significantly improved
CBT is usually therapy requiring 6 to 12 sessions so it is also cost-effective.
CBT is widely seen as the first choice of treatment in public health care systems such as the NHS
CBT AO3: Notsuitable for everyone
Lack of effectiveness for severe cases and for clients with learning disabilities
Depression can be so severe that clients cannot motivate themselves to engage with the cognitive work of CBT
They may not even be able to pay attention to what is happening in a session
The complex rational thinking involved in CBT makes it unsuitable for treating depression in clients with learning disabilities
CBT may only be appropriate for a specific range of people with depression
CBT AO3: Relapse rates
CBT is quite effective in tackling the symptoms of depression but there is concerns over how long the benefits last
Recent studies suggest that long-term outcomes are not as good as had been assumed
In one study depression was assessed in 439 clients every month for 12 months following a course of CBT
42% of the clients relapsed into depression within six months of ending treatment and 53% relapsed within a year.
CBT may need to be repeated periodically
CBT AO3: No side effects
CBT can be seen to be a good alternative to someone who does not enjoy taking drugs or does not want to have any side effects as a result of drugs
There will be no issue with having to find the right dose and other things to do with medication
