Psychopoathology Flashcards
Describe the characteristics of phobias
Behavioural
- panic
- avoidance
Emotional
-anxiety
Cognitive
- irrational beliefs
Describe the approach to treating OCD and evaluate it
SSRIs
- selective serotonin reuptake inhibitor
- increases levels of serotonin in synapses where it has been limited
SSRIs with therapy
- often drugs and therapy are paired to get the best results
- participants are able to engage more effectively in therapy
+ effective
> Soomoro compared SSRIs to placebos and found significantly better results
+ cost-effective
> cheap compared to psychological treatments so can save NHS money
>non disruptive to family lives
- side-effects
> eg, blurred vision, tremors, sleepy etc
> people may stop taking them as a result
Describe deviation from social norms and evaluate it
When an individuals behaviour is different from the accepted standards of society
\+ real life application >eg, antisocial personality disorder - culturally relative >norms vary a lot >eg, homosexuality - contextual >no set guidelines >eg, bikini on beach/in school
Evaluation of the treatment of phobias
+ effective
>Gilroy found a group of ppts that were treated with systematic desensitisation were much less fearful than a control group
+ patient-centred
>involves relaxation and causes less trauma
- cost effective
>only one session often
Evaluation of explanations of OCD
+ supporting evidence
> Nestadt = reviewed twin studies and found 68% of identical twins shared OCD compared with 31% of non identical.
- twin studies are flawed and non-identical twins are often exposed to different situations (eg exercise etc)
- ignores environmental factors
> past experiences may affect it or exposure to different things
Describe the characteristics of OCD
Behavioural
- compulsions = repetitive and reduce anxiety
Emotional
- anxiety and unpleasantness
Cognitive
- obsessive thoughts
Explain the approach to treating depression
Becks CBT
- identify automatic thought on negative triad
- tests these beliefs
- ‘patient as scientist’ involves them having homework in getting enjoyable moments from their lives to use as evidence
Ellis’ REBT
- disputing thoughts is the main aim
- often involves a vigorous argument
- making them realise their ideas are not true in the real world
Describe the characteristics of depression
Behavioural
- low activity levels
- insomnia/hypersomnia, increase/decrease weight loss
- self-harm
Emotional
- lowered mood
- lowered self esteem
Cognitive
- poor concentration
- dwell on the negative
Describe statistical infrequency and evaluate it
When an individual has a less common characteristic than the rest of the population
\+ real-life application >eg, intellectual disability disorder - unusual characteristics are positive >eg, IQ - labels can be harmful >can still live a very happy life
Evaluate the explanations for depression
+ practical application
>used in CBT therapy to identify and challenge thoughts
- a partial explanation
>patients experience anger/hallucinations
>only applies to some types of depression
Describe the two approaches to explain depression
Beck
- faulty information processing
- negative self schemes
- negative triad: world, view, self
Ellis (ABC)
- irrational thoughts triggered by an ACTIVATING EVENT
- this causes our BELIEFS
- there are CONSEQUENCES to having these beliefs
Describe the explanations of OCD
Genetic:
- Lewis found 37% of patients with OCD had parents with it and 21% had a sibling with it
- candidate genes = genes which create vulnerability for OCD
- it is polygenetic = Taylor found there could be up to 230 different genes involved including dopamine etc.
Neural:
- levels of neurotransmitters and brain structure is associated with OCD
- serotonin is responsible for relaying mood information and this doesn’t take place in OCD cases
- may be associated with impaired decision making (frontal lobes damaged)
How do we explain phobias and evaluation
Two-process model
Acquisition by classical conditioning
- ‘little albert’
- created a phobia in a 9 year old of a white rat using a loud noise
Maintenance by operant conditioning
- negative reinforcement means they will avoid the phobia as it takes away negative feelings so they will never get over it
+ real life application
>reasoning used in therapies and makes sense etc
- alternative motives
>positive feelings of safety may be a motive
What are the 4 definitions of abnormality
Statistical infrequency
Deviation from social norms
Failure to function adequately
Deviation of ideal mental health
Describe deviation from ideal mental health and evaluate it
When’s someone deposit meet the criteria for good mental health Jahoda
- cope with stress
- realistic view of the world
- good self esteem
- independent of others
- no distress
+ comprehensive definition
>covers a broad range of criteria and is a good starting point
- culturally relative
>eg, most suited to individualistic cultures - independence etc
- unrealistically high standard
>no one can always maintain these
>the majority would be classed as abnormal
