Psychopathology Flashcards
What’s psychopathology
Scientific study of mental disorders and abnormality
Definitions of abnormality
How many is there
Four
Definitions of abnormality
What is the statistical definition of abnormality
Defining abnormal according to the number of time we observe is and any behaviour which is rare or uncommon is abnormal
Definitions of abnormality
What does the statistical definition use
The normal distribution curve
Definitions of abnormality
Example with the statistical definition
IQ and intellectual disability disorder
Average IQ 100
Most have between 85-115
People below 70 and above 130 are abnormal
Those below would b diagnosed with the intellectual disability disorder
Definitions of abnormality
2 strengths of the statistical definition
Real life application of diagnosis
Definite cut off point
Definitions of abnormality
How is the statistical definition used in diagnosis of intellectual disability disorder
It’s a useful part of the clinical assessment as the severity of symptoms of those with mental disorders are compared to statistical norms
Definitions of abnormality
Why is the statistical definition used in diagnosis a strength
Gives a definitive cut off point which is objective therefore taking way the subjectivity of other definitions
Definitions of abnormality
How is there no value judgment in the statistical definitions
There is a clear cut off point so behaviour is not seen as unacceptable merely less frequent such as homosexuality
Definitions of abnormality
Why is ther absence of value judgement a strength for the statistic all definition
Statistical evidence that a person has a mental disorder can justify requests for psychiatric assistance
Definitions of abnormality
2 weaknesses of the statistical definitions
Unusual characteristics can be positive
Ignores cultural factors
Definitions of abnormality
Exceptions of unusual characteristics being positive using the statistical definition
Requires no treatment such as a high IQ pr exceptional sport skill
Abnormal yes dos to be sued in an negative sense
Definitions of abnormality
What can the statistical definition never be used for
Can never be used alone to make a diagnosis
Definitions of abnormality
What’s the social Norma’s definition of abnormality
States that behaviour which conforms to social norms is normals and behaviour that doesn’t is abnormal
Definitions of abnormality
What are social norms
Standards set by a society according to which is expects its members to behave
Are unwritten rules
Definitions of abnormality
What could happen if someone behaves ina. Way that doesn’t conforms to our social norms
May feel anxious or threatened by them and will be considered abnormal as long as society accepts it
Definitions of abnormality
What is antisocial personality disorder
Psychopath
According to DSM-5 people with is are impulsive aggressive and irresponsible
Definitions of abnormality
Characteristics of antisocial personality disorder
Absence of prosocial internal standards
Failure to conform to lawful or culturally normative ethical behaviour
Social judgement that psychopath is abnormal as they don’t conform to our moral standards
Definitions of abnormality
strength of the social norms definition
Real life application in diagnosing antisocial personality disorder
Definitions of abnormality
Why is diagnosing a strength of this definition
Clear set off of the characteristics of APD
Definitions of abnormality
Weakness of the social Norms definition
Subjective
Definitions of abnormality
Why is the social norms definition being subjective
a weakness social norms are based on the opinions of those in society and can be used to control others
Definitions of abnormality
What is the failure to functions definition
Can no longer cope with the demand of everyday life is considered abnormal and often not able to experience the usual range of emotions
Focuses on personal experiences lined with mental disorders
Definitions of abnormality
Examples of failure to functions
Unable to maintain basic standards of nutrition and hygiene or unable to hold down a job
Definitions of abnormality
When is someone failing to function adequately list
Personal distress
Maladaptive behaviour
Unpredictability
Irrationality
Observer discomfort
Violations of morals standard
Unconventionality
Definitions of abnormality
What’s the GAF scale
Assesses how well individuals cope with everyday life used by clinicians
Definitions of abnormality
What does the GAF a scale rate
Level of social occupational and psychological functioning
Definitions of abnormality
what is a strength of the failur to functions definitions
Degree of abnormality
Definitions of abnormality
Example for the degree of abnormality for the failure to function definition
GAF is an continuous scale
Definitions of abnormality
Why is assessing the degree of abnormality a strength of the failure or functioning definition
Can decide whop needs psychiatric help to what degree
Definitions of abnormality
What is a weakness of the failur to function definition
Abnormality is not always followed by failure to function
Definitions of abnormality
example for abnormality not always accompanied by failure to function
Harold shipman. Who had a good jib and well paid murdered 215 patients
Definitions of abnormality
What is the deviation from ideal mental health definition
Absence of jahodas characteristics of ideal mental health
Definitions of abnormality
What’s re jahodas characteristics for ideal mental health
-positive attitude towards oneself
-self actualisation
-autonomy
-resisting stress
-accurate perception of reality
-environmental mastery

Definitions of abnormality
What does this definition focus on
Behaviours and characteristics seen as desirable and the more which aren’t the met the more abnormal
Definitions of abnormality
What is a strength of the ideal mental health definition
Very comprehensive
Definitions of abnormality
Why is the ideal mental hamlets definition very comprehensive
Covers a broad range of criteria’s for mental health
Definitions of abnormality
Why is being comprehensive a strength of the ideal mental health definition
Is a useful tool
Definitions of abnormality
What is a weakness of the ideal mental health definition
Cultural relativism
Definitions of abnormality
How does the ideal mental health definition have cultural relativism
Some of the ideas in jehodas classification are specific to Western European and North American cultures
Definitions of abnormality
why is cultural relativism a weakness
Doesn’t include other cultures in definition
Phobias
What is a phobia
Type of anxiety disorder which can interfere with daily living
Phobias
What are phobias characterised by
Excessive uncontrollable extreme fear and anxiety triggered by and object place or situation
Phobias
What does a phobia produce
A conscious avoidance of the fears object or situation and the fear is out of proportion to nay real danger or risk presented by the phobic stimulus
Phobias
According to DSM 5 what are the categories of phobia an related anxiety disorder
Specific phobia (phobia of object or situation)
Social anxiety (phobia of social)
Agoraphobia (fear pr being outside )
characteristics of phobias
What are the three
Emotional
Behavioural;
Cognitive
characteristics of phobias
What are the emotional characteristics
Anxiety disorders by definition they involve and emotional response of anxiety and fear
characteristics of phobias
What is anxiety classed by
An unpleasant star of high arousal with feelings of worry or distress in te prescience of the phobic stimulus which prevent a relaxed feel and makes it difficult to experience a positive emotion
characteristics of phobias
What makes anxiety difference from fear
Can be long term
characteristics of phobias
What is fear in emotional characteristics
Immediate and extremely unpleasant string response which is experienced when in contact with the phobic stimulus
characteristics of phobias
What important about emotional characteristics of a phobia
Emotional responses are unreasonable
characteristics of phobias
What are the behavioural chatracterostics
How we behave when in contact with phobic stimulus
Panic and trying to escape
characteristics of phobias
What does panic situate as as a part of behavioural characteristics
Crying screaming running away fainting collapsing or vomiting
characteristics of phobias
How can children react for behavioural characteristics
Freezing clinging to a parent or having a tantrum
characteristics of phobias]
Two key behavioural characteristics
Avoidance
Endurance
characteristics of phobias
Avoidance as a behavioural characteristic
Avoiding coming in contact with phobic stimulus so may not be able to go to places and makes is hard to go about daily life
characteristics of phobias
What can the behavioural characteristic of avoidance affect
Work, education or social life
General day to day life
characteristics of phobias
Endurance as a behavioural characteristic
Alternative to avoidance as individual remains in prescience of phobic stimulus but continuous to experience its levels of anxiety often frozen still as may be unavoidable
characteristics of phobias
What’s are cognitive characteristic
Ways in which people process information and think about it
characteristics of phobias
What are the three cognitive characteristics
Selective attention to phobic stimulus
Irrational beliefs
Cognitive distortions
characteristics of phobias
Selective attention as a cognitive charteristic
If individual can see phobic stimulus hard to look away from it and all attention is on it
Not useful
characteristics of phobias
Irrational beliefs as cognitive characteristics
Irrational beliefs in relation to the phobic stimulus
characteristics of phobias
Cognitive distortions as cognitive characteristics
Phobic perceptions of the phobic stimulus may be disptorted
Behavioural approach to explain phobias
How can classical conditioning explain phobias
When someone has a phobia they will make an association between an object or situation and fear
Behavioural approach to explain phobias
How can operant conditioning link to phobias
Negative reinforcement so individual avoids situation that’s unpleasant and result in a desirable consequence of not feeling fear and anxiety
Reduction in fear reinforces the avoidance behaviour
Avoidance behaviour repeated and phobia maintained
Behavioural approach to explain phobias
Who is the two process model by and what year
Mowrer (1960)
Behavioural approach to explain phobias
What is the two process model
Based on the behavioural approach to phobias and states phobias are acquired by classical conditioning and then continue because of operant conditioning
Behavioural approach to explain phobias
Acquisition by classical conditioning according to the two process model using rat and loud noise
Before
Rats (NS) —> no response
Loud noise (UCS) —> fear (UCR)
During
Rats (NS) + loud noise (UCS) —> fear (UCR)
After
Rats (CS) —> Fear (CR)
Then generalised to similar objects
Behavioural approach to explain phobias
Maintenance by operant conditioning according to the two process model
Negative reinforcement – Individual avoids the phobic stimulus to avoid the fear anxiety they would have suffered
Positive reinforcement – reduction of fear is a desirable consequence
The avoidance behaviour is more likely to be repeated in the future as it has been reinforced
The phobia is therefore maintained
Behavioural approach to explain phobias
Two strengths of this
Good explanatory power
Effectiveness of behaviourist treatment
Behavioural approach to explain phobias
Good explanatory ppower\why was a this a step forward
Went beyond just using classical conditioning alone and explained how phobias could be maintained over time
Behavioural approach to explain phobias
Good explanatory power
What was the implications of this
For therapies explains why patients need to be exposed to the feared stimulus
Behavioural approach to explain phobias
Good explanatory power
Why is this a strength
Application to therapy means once a patient is prevented from practicing avoidance characteristics the behaviours ceases to be reinforced and declines
Behavioural approach to explain phobias
Effectiveness of behaviourist treatment
Example
Treatment such as systematic desensitisation in assessing phobic symptoms are effective
Behavioural approach to explain phobias
Effectiveness of behaviourist treatment
Why is this a strength
Lends support to behaviourist explanations of phobias
Behavioural approach to explain phobias
2 weaknesses
Alternative explanation for avoidance behaviour
Incomplete expanlantion of phobias
Behavioural approach to explain phobias
Alternative explanantion for avoidance behaviour
Exception
Not all avoidance seems to be because of anxiety reduction
Behavioural approach to explain phobias
Alternative explanantion for avoidance behaviour
Example of agoraphobia
Evidence shows that at least some of the avoidance behaviour is for safety reasons rather than avoiding the phobic stimulus which explains why some agoraphobics can leave the house with a trusted person with little anxiety
Behavioural approach to explain phobias
Alternative explanantion for avoidance behaviour
Why is this a weakness
This is a problem for the two process mode, as it suggests avoidance is motivated by anxiety reduction
Behavioural approach to explain phobias
Incomplete explanation of phobias
Why is it not enough
Even if except these involved futher explanation is needed such as evolutionary factors
Behavioural approach to explain phobias
Incomplete explanation of phobias
How are evolutionary factors involved
We easily acquire phobias of things that’s have been a source of danger in our past such as snakes and it is adaptive to acquire such fears
Behavioural approach to explain phobias
Incomplete explanation of phobias
Why is this a weakness
The two process model fails to account for this and neglect evolution history
Behavioural approach to treating phobias
What therapies do need to describe and evaluate
Systematic desensitisation
Flooding
Behavioural approach to treating phobias
What is systematic desensitisation
Designed to reduce an unwanted response eg anxiety to a stimulus and teaching the sufferer to relax in the prescience of the phobic stimulus
Essentially new response to the phobic stimulus is learned
Phobic stimulus is paired with relaxation “counter conditioning “
Behavioural approach to treating phobias
What is flooding
Phobic patient i exposed to an extreme form of phobic stimulus to rescue anxiety triggered by it
Without option of avoidance quickly learned stimulus is harmless
‘Extinction’ learned response extinguished when CS is encountered without UCS
Behavioural approach to treating phobias
What are the three steps of systematic desensitisation
- The anaixety hierarchy
- Relaxation training
- Exposure to anxiety hierarchy
Behavioural approach to treating phobias
What is the anxiety hierarchy and how is it constructed
List of situations put tog ether by patients and therapists related to phobic stimulus that provoke anxiety arranged in order from least such as thinking about phobic stimulus to most frightening such as holding the stimulus
Behavioural approach to treating phobias
What is relaxation training
Therapist teacher the patient to relax as deeply as possible
Behavioural approach to treating phobias
What can be taught in relaxation training
Breathing exercises or mental imagery techniques
Imagine in relaxing situations
Meditation
Alternatively drugs such as valium
Behavioural approach to treating phobias
What is exposure to the anxiety hierarchy
Patient exposed to hierarchy while remaining in a relaxed state over several sessions starting at the bottom and when patient is relaxed in the presence move up the hierarchy
Behavioural approach to treating phobias
How long can systematic desensitisation take
Up to a month
Behavioural approach to treating phobias
What is the result if the treatment is successful of systematic desensitisation
Patient can stay relaxed in situation high on the anxiety hierarchy
Behavioural approach to treating phobias
2 strengths of systematic desensitisation
Suitable for a wide range of patients
Less traumatic
Behavioural approach to treating phobias
Why are some treatments not suitable for patients
Eg flooding and CBT aren’t suited to some patients
Some people with learning difficulties wont be able to understand what’s happening our engage with the CBT that require you to reflect what ur thinking
Behavioural approach to treating phobias
Why is being suitable for a wide range of patients a strength
More access of treatment for patients so quality of life improved
Behavioural approach to treating phobias
What is systematic desensitisation less traumatic then
Flooding
Behavioural approach to treating phobias
What is pleasant about systematic desensitisation
Includes elements that are pleasant such as learning relaxation techniques
Behavioural approach to treating phobias
How is systematic desensitisation shown to be less traumatic
Reflected by low refusal rates for starting treatment and low attrition rates
Behavioural approach to treating phobias
2 weaknesses of systematic desensitisation
Symptom substitution
Ethical considerations
Behavioural approach to treating phobias
What is symptom substitution
When one phobia disappear another may appear in its place
Behavioural approach to treating phobias ]
What is the evidence for symptom substitution
Very missed however behavioural therapists tend to not believe it happens at all
Behavioural approach to treating phobias
Why is symptom substitution a weakness
Disregard the point in the treatment in the first place
Behavioural approach to treating phobias
What are the ethical considerations
Systematic desensitisation can be psychologically harmful
And the cost benefit analysis may regard long term benefits of eradicating the phobia as outweighing the short term cost distress
Behavioural approach to treating phobias
Flooding
What is flooding
Involves a exposing phobia patients tot heir phobic stimulus but without gradual build up in an anxiety hierarchy so involves immediate exposure to a very frightening situation
Behavioural approach to treating phobias
Flooding
How long does it often last
Typically shorter than systematic desensitisation sessions with one session lasting two to three hours
Behavioural approach to treating phobias
Flooding
What are the three stages
- Immediate direct exposure
- Prevention of avoidance
- Continuance until anxiety has reduced and fear extinguished
Behavioural approach to treating phobias
Flooding
What is immediate direct full exposure
Presenting the phobic stimulus to the patient directly in comparison to systematic desensitisation where there’s a gradual exposure
Behavioural approach to treating phobias
Flooding
What’s prevention of avoidance
Flooding stops the phobic response very quickly
This may be because without the option of avoidance behaviour the patient quickly learns that the phobic stimulus is harmless
Behavioural approach to treating phobias
Flooding
What is continuing until anxiety has receded abd fear extinguished
Learned response extinguished when the conditioned stimulus is encountered without the unconditioned stimulus so CS no longer produced the CR ‘extinction’
Behavioural approach to treating phobias
Flooding
strength
Cost effective
Behavioural approach to treating phobias
Flooding
How is being cost effective strength
Studies comparing flooding to cognitive therapies have found that flooding is highly effective and quicker than alternatives
This quick effect is a strength
The patients are free of their symptoms sooner and treatment is therefore cheaper
Behavioural approach to treating phobias
Flooding
2 weaknesses
Less traumatic
Not suitable for all patients
Behavioural approach to treating phobias
Flooding
Why is it traumatic
Highly psychologically harmful as being exposed to phobic stimulus and some patients unwilling to see it through to the end
Behavioural approach to treating phobias
Flooding
Why is it not suitable for all patient
Eg with heart conditions
Extreme levels of anxiety caused by confrontation with the geared object or situation can be harmful on the body
OCD
How does the DSM characterise OCD
is repetitive behaviour accompanied by obsessive thinking and is characterised by either obsessions and/or compulsions
OCD
What are obsessions
Internal component of recurring intrusive thoughts, image etc
Things people think about often inappropriate ideas leading to extreme Anxiety
OCD
What are compulsions
External component of what people do as a result of the obsessions often uncontrollable urges repetitively perform tasks and behaviours
OCD
Why are compulsions compulsions
Attempt to reduce distress or feared events and only temporary solutions of have no other way of coping so rely on them
Can include avoiding a situation that triggers obsessive ideas
OCD
What causes high leve;s of anxiety with ocd
Most sufferers realise there obsessions and compulsions are excessive and inappropriate but can’t control them leading to higher anxiety
OCD
What do symptoms of ocd often overlap with
Other conditions such as Tourette’s and autism
OCD
How many people have ocd
Around 2% of the populations
OCD
Gender differences with ocd
No real difference in prevalence
Preoccupation with contamination and cleaning are more common in females
Males focus more on religious and sexual obsessions
