pyschopathology Flashcards
what is psychopathology?
the study of psychological disorder
what are the two ways on deciding if a person’s behaviour and/or psychological state are sufficiently unusual to justify diagnosing and treating them for psychological disorder?
statistical infrequency
deviation from social norms
what is statistical infrequency?
occurs when an individual has a less common characteristic (e.g being more depressed or less intelligent) than most of the population
how is the statistical infrequency approach used when measuring intelligence?
average IQ = 100
in a normal distribution, most people (68%) have a score of 85-115
only 2% of people have a score below 70 (these people are considered abnormal and are liable to recieve a diagnosis of intellectual disability disorder)
evaluation: how is it a strength that statistical infrequency is useful?
(give an example of statistical infrequency)
used in clinical practice as a part of formal diagnosis and a way to assess the severity of symptoms.
e.g diagnosis of intellectual disability disorder requires an IQ of below 70 (bottom 2%)
example of statistical infrequency: Beck depression inventory (score of 30+ [top 5% respondents] is widely interpreted as severe depression)
shows that the value of statistical infrequency criterion is useful in diagnostic and assessment processes
evaluation: how is it a limitation that infrequent characteristics can be positive as well as negative?
for every person with an IQ below 70 there is another with an IQ above 130
these examples show that being unusual or at one end of a psychological spectrum does not make someone abnormal (we wouldn’t think someone abnormal for having a high IQ or someone with a low depression score on the BDI as abnormal)
means that although statistical infrequency can form part of assessment and diagnostic procedures, it is never sufficient as the sole basis for defining abnormality
what is deviation from social norms?
concerns behaviour that is different from the accepted standards of behaviour in a community or society
how are social norms specific to the cultures we live in?
social norms may be different for each generation for each generation and different in every culture (relatively few behaviours that are universally considered abnormal)
e.g homosexuality was considered abnormal in out culture in the past and continues to be viewed as abnormal (and illegal) in some cultures
(april 2019 brunei introduced new laws that make sex between men an offence punishable by stoning to death)
what is an example of deviation from social norms?
person w antisocial personality disorder (psychopathy) is impulsive, aggressive and irresponsible
according to DSM-5 (manual used to diagnose mental disorder) one important symptom of antisocial personality disorder is ‘an absence of prosocial internal standards associated with failure to conform to lawful and culturally normative ethical behaviour’
showing psychopathy would be considered abnormal in many cultures
evaluation: how is it a strength that deviation from social norms is useful?
used in clinical practice
e.g key defining characteristic of antisocial personality disorder is failure to conform to culturally acceptable ethical behaviour (recklessness, aggression) and are all deviations from social norms
shows that the deviation from social norms criterion has value in psychiatry
evaluation: how is the variability of social norms in different cultures and situations a limitation?
person from one culture group may label someone from another group as abnormal using their standards rather than the person’s standard.
e.g experience of hearing voices in norm in some cultures (msgs from ancestors) but would be seen as a sign of abnormality in most parts of UK
means it is difficult to judge deviation from social norms across different situation and cultures
what is meant by ‘failure to function adequately’ ?
occurs when someone is unable to cope with ordinary demands of day to day living
(e.g unable to maintain basic standards of nutrition and hygiene, cannot hold jobs or maintain with relationships around them)
what were the signs proposed by Rosenhan and Seligman (1989) that can be used to determine if someone is failing to function adequately?
- when a person no longer conforms to standard interpersonal rules (e.g maintaining eye contact and respecting personal space)
- when a person experiences severe personal distress
- when a persons behaviour becomes irrational or dangerous to themselves or others
evaluation: how is it a strength that the failure to function criterion that it represents a sensible threshold for when people need professional help?
25% of people in the UK will experience a mental health problem in any given year - mental health charity Mind
however many people press on in the face of severe mental symptoms and it tends to be at the point that we cease to function adequately that people seek professional help or referred for help by others
means the criterion means that treatment and services can be targeted to those who need them the most
evaluation: how is it a limitation of failure to function that it is easy to label non-standard lifestyle choices as abnormal?
it can be difficult to determine when someone is failing to function and when they have simply chosen to deviate from social norms (e.g New Age travellers who don’t work or live in a permanent accommodation, spiritualists who take part in religious rituals and communicate with the dead)
people who make unusual choices and have alternative lifestyles are at risk of being labelled abnormal and their freedom of choice may be restricted and they could be discriminated against.
what is deviation from mental health?
occurs when someone does not meet a set of criteria for good mental health
What is the criteria of ideal mental health suggested by Jahoda (1958)?
- no symptoms or distress, can cope with stress
- are rational and can perceive ourselves accurately, can self-actualise (strive to reach our potential)
- have a realistic view of the world, good self esteem and lack guilt
- independent of other people, can successfully work, love and enjoy our leisure
evaluation: how is it a strength that the ideal mental health criterion is highly comprehensive?
it covers most of the reasons why we might seek or be referred for help with mental health (means an individuals mental health can be discussed meaningfully with a range of professionals who might take different theoretical views
means that the ideal mental health provides a checklist against which we can assess ourselves and others and discuss psychological issues with a range of professionals
evaluation: how is it a limitation that its different not equally applicable across a range of cultures?
some of jahoda’s criteria for ideal mental health are firmly located in the context of of the US and Europe
the concept of self actualisation would be dismissed as self indulgent in much of the world
in Europe there is variation in the value placed on personality independence e.g high in Germany and low in Italy
Meaning it is difficult to apply the concept of ideal mental health from one culture to another
what is a phobia?
an irrational fear of an object or situation
what are the categories of phobia and related anxiety disorder recognised by DSM-5?
SPECIFIC PHOBIA: phobia of an object (animal or body part) or a situation (flying or injections)
SOCIAL PHOBIA: phobia of asocial situation such as public speaking or using a public toilet
AGORAPHOBIA: phobia of being outside or in a public place
what are the behavioural characteristics of phobias?
PANIC
AVOIDANCE
ENDURANCE
how is panic shown as a behavioural characteristic of phobias?
PANIC: person w phobia may panic in response to phobic stimulus by showing. range of behaviours: crying, screaming running away
children may react differently by freezing, clinging or having a tantrum
how is avoidance shown as a behavioural characteristic of phobias?
person w phobia puts a lot of effort to prevent coming into contact with the phobic stimulus (unless they are making a conscious effort to face their fears)
e.g someone w a fear of public toilets may have to limit the time they spend outside the home in relation to how long they can last without a toilet
-> interferes with work, education and social life
