Q

Abnormality-evaluation

A

Strengths:
-Access of subjective experience of the patient
-Comprehensive as it covers broad criteria for mental health
Weaknesses:
-Deviation from social norms depends on person as they can just choose to behave that way, ex) religion can be seen as irrational
-Judgement made by psychiatrist is subjective
-Jahoda’s list may only apply to individualist culture
-Standards are too high
-Incorrect labelling of people ex) people losing jobs will obvi feel depressed, doesn’t mean they have problems

  2. irrational beliefs
    ex. social phobias can involve thoughts ‘I must always be smart’-increase pressure

A
  1. Obsessive thoughts (recur over and over again)
  2. Cognitive strategies to deal with obsessions-people adopt coping strategies to manage anxiety, can seem abnormal to others

Q

Two process model

A
  1. Classical conditioning
    -Baby called Albert had no anxiety, shown a rat but every time rat was near they made a frightening sound. Noise (UCS) created fear (UCR), so rat (NS) was associated with UCR and became CS to produce CR
    -generalised to similar objects such as rabbit
  2. Operant conditioning
    -Happens when behaviour is reinforced (rewarded) or punished (positive/negative reinforcement)
    -Avoidance results in desirable consequence-repeated

Q

Two process model-evaluation

A

Strengths:
-Application to therapy as it explained how it was maintained

Weaknesses:
-Some avoidance happens by positive feelings of safety, avoidance is to stick with safety factor
-Evolutionary factors may play a part, phobic stimulus is dangerous and avoidance is adaptive (biological preparedness-innate predisposition to acquire fears)
-Some phobias are not followed by a trauma
-Doesn’t explain cognitive aspect of phobia

Q

Systematic desensitisation

A

Behavioural therapy to reduce anxiety through classical conditioning and counterconditioning (learning different response), reciprocal inhibition (can’t feel multiple emotions at once)

  1. Anxiety hierarchy-list of situations related to phobic stimulus, least to most
  2. Relaxation-patient encouraged to relax/mental imagery techniques/drugs such as valium
  3. Exposure-exposed to stimulus in a relaxed state, encouraged to maintain relaxed

Q

Flooding

A

immediate exposure to phobic stimulus

-Patient immediately leans that the simulus is harmless (extinction)
-Learned response extinguished when conditioned stimulus (spider) is encountered without the unconditioned stimulus (being bitten) so no longer produce conditioned response (dear)
-Some exhausted by their own fear response
-INFORMED CONSENT needed

17
Q

Systematic desensitisation-evaluation

A

Strengths:
-effective, Gilroy et al did systematic desensitisation and relaxation w/o exposure, desensitisation were less fearful
-Suitable for diverse range of patients
-Preferred by patients as it is less traumatic, and relaxing is pleasant

18
Q

Flooding-evaluation

A

Strengths:
-Cost effective and quicker

Weaknesses:
-Complex phobias such as social phobias are harder to treat (as cognition may be involved)
-Traumatic for patients, unethical (not preferred)

19
Q

Beck’s theory

A
  1. Faulty info processing-black and white, focus on the black
  2. negative self schema (info about ourselves)
  3. Negative triad
    -of the world-‘world’s unfair’ (loss of hope)
    -of the future-‘there’s no chance it will get better’
    -of self-‘I am a failure’ (low self esteem, depression)
20
Q

Ellis’s ABC model

A

A-activating event occurs which may trigger emotional beliefs

B-beliefs
-musturbation: belief that we should be perfect
-I can’t stand it itis-belief that any mistake is a major disaster
-Utopianism: life should always be fair

C-Consequences due to irrational beliefs, emotional and behavioural

21
Q

Beck’s theory-evaluation

A

Strengths:
-Supporting evidence on negative schemas and triad (Grazioli and Terry found that depression associated with cognitive vulnerability)
-Practical application in CBT as it can challenge negative schemas and triad

Weaknesses:
-Can’t explain why some depressed people are angry, or coward syndrome (delusion that there are zombies)

22
Q

ABC model-evaluation

A

Strengths:
-Practical application to CBT
-Insecure attachment is vulnerable to depression

Weaknesses:
-Only explain reactive depression and not ones without any clear cause
-Can’t explain anger associated with depression, or how some suffer hallucinations
-Could lead to cognitive primacy (emotions are influenced by cognition) but other theories suggest that emotion comes after an event

23
Q

CBT

A

Identifies and challenges irrational problems, therapist and patient work together
Behavioural activation-patient tries enjoyable activities

CBT-Beck
-identifies negative triad and challenges them directly
-homework task for patents (‘patient as scientist’)
-Therapist challenges irrational thoughts through evidence

CBT-Ellis (REBT)
-Extends ABC model to ABCDE model (D-dispute, E-effect)
-Argument on irrational thoughts (dispute) to challenge the irrational thought (effect)

24
Q

CBT-evaluation

A

Strengths:
-Effective, March et al showed 81% improvement in antidepressants and 86% CBT and drug

Weaknesses:
-May not work with severe cases where patient isn’t motivated to engage
-Result may be due to therapist patient relationship (having someone to talk to is important)
-Patient want to explore their past and the effect of it, CBT only focuses on present and future
-Overemphasis on cognition and undermining circumstance of patient’’s living, demotivate people to change their situation

25
Q

Genetic explanation to OCD

A

Diathesis stress model-certain genes can make person more susceptable to mental health problems but environment stress also needs to be present

  1. Candiate genes are genes that create vulnerability to OCD, such as 5HT1-D beta affecting transport of serotonin across synapse
    -OCD is polygenic (multiple genes), Taylor found that up to 230 genes are involved, dopamine, serotonin involved
  2. Aetiologically heterogeneous-origins have different causes, could be due to genetic variation
26
Q

Neural explanation to OCD

A
  1. Low levels of serotonin (helps to regulate mood)
  2. Decision making system-OCD related to impaired decision making, linked to abnormal functioning of frontal lobes (responsible for decision making and logical thinking)
    left parahippocampal gyrus is liked to processing unpleasant emotions
27
Q

Genetic explanation to OCD-evaluation

A

Strengths:
-Support from twin studies, Nested et al found that 68% identical twins shared OCD compared to 31% non identical ones

Weaknesses:
-Lack of application due to having too many candidate genes
-Environmental factors are also important, Cromer et al found that over half of patients had traumatic event in the past, OCD more severe with those with multiple trauma

28
Q

Neural explanation of OCD-evaluation

A

Strengths:
-Support from antidepressants as it can treat OCD
-Those with OCD also become depressed, could be linked to serotonin system
Weaknesses:
-Unclear evidence on which neural mechanisms are involved, sometimes brain is involved and sometimes doesn’t
-Causation doesn’t mean correlation

29
Q

Drug therapy for OCD

A

-SSRI prevent the reabsorption and breakdown of serotonin, and increase its levels in the synapse and the amount of it being passed to postsynaptic neuron
-takes over 4 months for it to have an impact
-Reduce emotional symptoms so patients can engage with CBT better
-Tricyclics (antidepressant) such as clomipramine used, but more side effect
-SNRI (selective noradrenaline reuptake), increase serotonin and noradrenaline

30
Q

Drug therapy for OCD-evaluation

A

Strengths:
-Reasearch support for OCD-better results for SSRI compared to a placebo, symptoms decline 70% of the time
-Cheap compared to CBT and non disruptive to life

Weaknesses:
-Negative side effects such as indigestion, blurred vision
-Some contrasting evidence, as placebo and SSRI had similar results, and drug companies could sponsor it
-some OCD is followed by trauma so inappropriate to treat with just drugs
