Q

Definitions of abnormality - statistical infrequency

A

Defining abnormality in terms of statistics. Behaviour rarely seen is a statistical infrequency.
E.G. IQ and Intellectual disability disorder: IQ below 70 is statistically abnormal.

Real life application - useful part of clinical assessment to compare with norms.
Unusual characteristics can also be positive - IQ above 130 are just as unusual as those below 70.

Q

Definitions of abnormality - deviation from social norms

A

Abnormality is based on societal expectations of behaviour. Social norms may be different for each generation and culture.
E.G. Antisocial personality disorder: impulsive, aggressive, irresponsible, failure to conform to normative behaviour.

Not a sole explanation - shouldn’t be used by itself.
Cultural relativism - social norms vary from cultures and generations.

Q

Definitions of abnormality - failure to function adequately

A

Inability to cope with everyday life - not being able to maintain jobs, relationships.
Rosenhan and Seligman - signs of failure to cope…
- no longer conform to interpersonal rules
- experience personal distress
- irrational / dangerous behaviour

Recognises patients perspective
Subjective judgement - may say they are distressed but are not suffering.

Q

Definitions of abnormality - deviation from ideal mental health

A
Places emphasis on what makes someone normal and psychologically abnormal.
Jahoda: criteria for mental health:
- no symptoms/ distress
- ability to self-actualise
- ability to cope with stress
- self esteem is good, lack guilt

Comprehensive, covers a broad range of criteria
May be culturally relative - self-actualisation may be seen as self-indulgent.
Unrealistically high standard for mental health, but makes it clear where people can improve.

Q

Behavioural approach to phobias - Two Process Model: Mowrer

A

Acquisition by classical conditioning - UCS triggers fear response (UCR), NS is associated with UCS, NS becomes a CS, produces fear (e.g. Little Albert)

Maintenance by operant conditioning (negative reinforcement) - phobic avoids phobic stimulus to escape anxiety. Reduction of fear reinforces the avoidance behaviour and the phobia is maintained.

Q

Behavioural approach to phobias evaluation

A

Important implications for therapy

Incomplete explanation - biological preparedness we are innately prepared to fear some things more than others - we easily acquire phobias of things that were a danger in our evolutionary past.

Q

Treatment for phobias evaluation

A

SD: Effective and long-lasting, suitable for a diverse range of patients, tends to be acceptable to patients (low refusal rates)
Flooding: Less effective for some types of phobias (social phobias), traumatic for patients (often unwilling to see it through to the end).

Q

Cognitive approach to depression - Beck

A

Faulty information processing.
Negative schema
Negative triad

Practical application in therapy - negative triad identified and challenged in therapy = successful.
Good supporting evidence - Grazioli and Terry: women identified as vulnerable before birth were more likely to suffer post-natal depression - cognition causes depression.

Q

Cognitive approach to depression - Ellis

A

ABC model:
Activating event - irrational thoughts during negative events
Beliefs - irrational beliefs: ‘musterbation’ = we must always succeed, ‘utopianism = ‘the world us always be fair
Consequences - emotional and behavioural

Partial explanation of depression - only applies to some types.
Cognitions may not cause all aspects of depression - emotions, e.g. distress and anxiety = physical energy to emerge some time after the causal event.

Q

Treatment for depression

A

Cognitive behaviour therapy - Beck
Patient and therapist work together, involves challenging negative thoughts related to negative triad, encouraged to test the reality of irrational beliefs, set ‘homework’ to prove patient’s beliefs incorrect.

Q

Treatment for depression evaluation

A

Effective - after 36 weeks, 81% of CBT group, 81% of drug therapy group, 86% of CBT + anti-depressant group were significantly improved.

May not work for severe cases - cannot motivate themselves to take on hard cognitive work.

‘Present focus’ may ignore important aspect of patient’s experience.

17
Q

Biological explanations for OCD (GENETIC)

A

Genetic explanation - candidate genes: serotonin genes.
Lewis: observed his OCD patients: 37% had parents with OCD, 21% had siblings with OCD.
Diathesis stress model shows certain genes leave individuals more vulnerable to mental disorders.

Twin studies = supporting evidence - Nestadt: 68% of identical twins shared OCD.
Environmental risk factors are also involved - traumas cause OCD.

18
Q

Biological explanations for OCD (NEURAL)

A

Low levels of serotonin lowers mood.
Decision-making systems in frontal lobes are impaired.
Parahippocampalgyus (associated with unpleasant emotions) functions abnormally in OCD

Anti-depressants work on serotonin system are effective in reducing OCD symptoms.
Biological abnormalities could be a result of OCD rather than its cause - various neurotransmitters and structures don’t function normally in patients with OCD.
Comorbidity with depression.

19
Q

Treatment for OCD - SSRI’s

A

Selective serotonin reuptake inhibitor - prevent the reabsorption and breakdown of serotonin in the brain, increases its level in the synapse - serotonin stimulates postsynaptic neuron

Dosage - fluoxetine = 20MG, takes 3-4 months of daily use to impact symptoms.
Drugs reduce emotional symptoms (anxiety)
Patients can engage more effectively with CBT as a result.

20
Q

Other treatments for OCD

A

Tricyclics - clomipramine: same effect on serotonin systems, side effects more severe.
SNRI - serotonin noradrenaline reuptake inhibitor - increases levels of serotonin as well as noradrenaline.

21
Q

Drug therapy (OCD) evaluation

A

Effective at tackling symptoms - Soomro: reviewed 17 studies comparing SSRI’s to placebos. All 17 showed better results for SSRI’s. Typically, symptoms reduce for around 70%.
Cost effective, non disruptive.

Side effects - indigestion, blurred vision, loss of sex drive.
Health ‘professionals’ - many are poorly trained to identify psychological problems and so medication prescription is more commonly used.
May not be appropriate to use drugs following trauma.
