Title: Psychology Revision
1Psychology Revision
2What Is Abnormality?
- Deviation from the social norm.
- It allows minority groups to be classified.
- It seems intuitively correct, we tend to think of
mental illness as people behaving abnormally,
I.e., against the social norm those with mental
illness often do break social norms. - This may not be a good gauge of abnormality
because our idea of normality changes over time,
e.g., homosexuality is no longer against the
social norm there are also cultural variations
with regard to social norms. - Criminals often break social norms, but are not
thought of as mentally ill. - Not everyone who suffers mental illness will
break social norms, e.g., those with clinical
depression, intense anxiety. - Deviation from the social norm is not always
indicative of mental illness, e.g., frequency
context of behaviour also need to be taken into
account (wearing pyjamas in the street might be
abnormal, but not in an emergency, such as your
house catching fire)
3What is Abnormality?
- Deviation from the statistical norm.
- If most people can do something, it seems logical
to assume those who cant must be abnormal. - It provides a clear cut-off point for those who
are different. However, being different does
not classify abnormality. - It can be a good thing to deviate, e.g., gifted
talented people deviate from the statistical
norm in a good way. - Sometimes statistics can change, e.g., IQ levels
have increased over the past 100 years, this
implies that someone with a certain score 100
years ago would now be regarded as mentally
retarded. - Homosexuality is statistically abnormal but this
does not mean that homosexuality should be
categorised as a form of mental illness. - Statistics arent always a valid measure of
something (e.g. Intelligence). - One score may not accurately reflect behaviour or
cognition it may also be necessary to use more
than one measure ( more than one score) to get
an accurate gauge of statistical average
behaviour/attitudes.
4What is abnormality?
- Personal Suffering/Distress
- It is good because it takes into account the
subjective nature of suffering it is different
for everybody - However, some people may not be aware of their
condition - People have different ideas about what it is to
suffer it is therefore very hard to measure
quantify so too subjective to be of much value - Some may exaggerate symptoms when defining mental
health - It relies on the sufferer to show signs of their
condition - Psychopaths may feel no distress whatsoever but
are nevertheless regarded as having a clinical
condition - Failure to function adequately
- Maladaptiveness of behaviour when the behaviour
is not adapted well to a situation then it will
cause abnormality - Condition is often very obvious
- However, it is based on value judgements - too
subjective - Society may be the problem, not the individual
5What is abnormality?
- Absence of normality
- Deviation of the expected - the mental health
criteria - Jahoda (1958) wrote criteria for ideal mental
health - Freedom from mental illness
- Self-actualisation
- Autonomy
- Mastery of the environment
- However, these are based on value judgements
- Values change all the time
- Highly context-significant
- It is difficult to keep with definite
characteristics - People have different ideas about
self-actualisation/none at all
6Problems with defining abnormality
- The problems with all of these definitions is
that there is no one, shared characteristic
implying that no one definition is enough - Theres no fixed point between normal and
abnormal - a continuum
7Classification Systems
- Advantages
- Allows people to get treated more effectively due
to more minority groups not lumping people
together - A way of investing different situations
- Allows people to pool information and research
that group - The first step towards diagnosis gt treatment
8Validity
- Aeitological Validity
- That people with a particular disorder have the
same causal factors - Concurrent Validity
- When you have on-set of symptoms, you have
associated conditions e.g. age of onset, social
factors - Predictive Validity
- Whether the results match up with whats predicted
9Validity
- The Diagnosis should be a genuine accurate
reflection of the condition diagnosed. This is
not as straightforward as it seems - Rosenhan (1973) Being Sane in Insane Places is
a classic study which shows the problems of
validity with regard to clinical conditions.
(NB., One Flew Over The Cuckoos Nest). - Bi-Polar Disorder (manic depression) is often
misdiagnosed as Schizophrenia because the
symptoms can be very similar. - Different types of conditions may often have
similar symptoms, e.g., paranoia is associated
with schizophrenia substance abuse
10Reliability
- Both physical and clinical conditions are not as
easy to diagnose as you may expect - Reliability for angina and tonsillitis is lower
than that of schizophrenia - Cooper et al. (1972) showed psychologists had
different diagnoses for the same conditions when
watching a video clip of patients. Americans were
twice as likely to diagnose schizophrenia than
British, who diagnosed bipolar disorder more
often. This proves that a classification system
relies on more than just symptoms - Spitzer Williams (1985) found that
psychologists agreed on a diagnosis only 50 of
the time - Zigler Phillips (1961) found that agreement for
clinical categories was 54-84 e.g. personality
disorders
11Reliability
- Kendell (1975) found only a 33-57 agreement
about more specific definitions - Davison Neale (1994) Psychosexual conditions
are more reliable (92) because it is easier to
diagnose unlike any other disorder. For
somatoform disorders it drops to 0.54 - Fallek Moser (1975) found a 66 concordance
rate with the post mortem and the cause of death
on the certificate - A problem with a lot of diagnoses is that they
are nebulous (vague)
12Interviews
- Often the diagnosis takes place through a
clinical interview, which are unstructured so the
same questions arent asked each time so
different conclusions can be drawn through the
different information - Self-report is also another unreliable method to
diagnose conditions - These methods lack objectivity so reliability and
validity are harder - Doctors may not be given the same information
each time and in the same manner - Doctors also only spend a short amount of time
with each patient, so accurate diagnosis is
difficult - Some people may exaggerate symptoms to get a
result (e.g. faster cure, sick leave etc.)
13Classification Systems
- General Problems
- Creates a circular argument
- Do symptoms classify the illness or does the
illness classify the symptoms - They may not help if theres no treatment
available - Mental health is a continuum, and there is no
clear cut-off point, so conditions will not fall
into a particular category - Goffman argues that classifying people
stigmatises them - It attaches a negative label, to which people
will make assumptions which is unfair - Scheff believes that this will induce
self-fulfilling prophecy, whereby people will
live up to their label - Heather introduce the concept of
institutionalisation, believing that people can
become dependant on their surroundings
14Classification Systems
- General Problems
- Szasz thought that classifying people often
caused them to medicalize behaviour - meaning they will use drug treatment for all
behaviour, when really the people are just
unpredictable people who have problems with
living. By classifying them, society is trying to
control unpredictable people. It is easier to
blame an individual than to blame society. - Blaney (1975) however, believed labelling people
was quite humane. - Its not saying that you are bad, but merely
allowing you to know its not your fault - Sometimes however, the condition can be used as a
scapegoat for people who do not take
responsibility
15Classification Systems
- General Problems
- R.D. Laing thought that schizophrenia is not a
breakdown, its a break-through. - To deal with it rationally, and confronting it is
better than just labelling it as a disorder - It has focus more in the individual, and not the
cause (e.g. families) - It diagnoses the symptoms and not the individual
- It should not be diagnosed due to social norms
- McCrae and Costa (1992) introduced a theory of
5-factor analysis - Agreeableness Openness to experience/Not
- Stable/Neurotic
- Conscientious/un-conscientious
- However this approach only applies to
personality, and there is not clear cut-off point - It ignores social facilities, subjective distress
and biological factors
16International Classification of Disease (ICD)
- ICD
- This involves one broad category, and describes
symptoms - It matches references between causes
- It is more 1-dimensional than the DSM
- It links class and culture, looking at a variety
of cultures, not like DSM, which is westernised - However, this can cause a lot of cultural
baggage to be carried
17Diagnostic Statistical Manuel of Mental
Disorders (DSM)
- DSM is the US method of diagnosing mental
disorders (NB., Western psychiatric bias). - It is a multi-axial system there are 5 axis.
For a diagnosis to be made the patient must meet
criteria on at least the first 3 axis (although
all 5 are considered). - Evaluation of DSM
- DSM is continually updated to take into account
new research changes in cultural attitudes,
this helps to improve reliability validity. - The inter-rater test-retest reliability of some
disorders is now very good however, other
disorders remain low, notably childhood disorders - The multi-axial nature of DSM improves validity
because diagnosis is not based on one aspect or
feature of behaviour/cognition, social factors
level of personal functioning is also considered,
for example. - DSM has been prone to cultural/social bias, e.g.,
homosexuality was on DSM until 1980, now Maths
phobia is on DSM.
18Cultural factors affecting the diagnosis of
clinical conditions
- Cultural ideas differ in some cultures, and
between some cultures - Banyard (1996) found that 5 of the UK population
is black, but 25 of psychiatric patients are
black - This could be due to racism, or that its harder
to be a minority group therefore more conditions
arise, or diagnoses could be culturally biased
(made by white, middle-class Drs) - Lilwood (1992) believed axis V (G.A.S. (1-100))
placed too much emphasis on the nuclear family.
Different families have different cultural
traditions, and behaviour is different for
different cultures - Davidson and Neale (1994) found that
Asian-American women are seen as more
subservient/withdrawn. Emphasis may be placed on
a disorder, but their culture may make their
behaviour normal to them - It can be bad to acknowledge some cultural
differences - OConner (1989) found native Americans get lower
IQ scores than white Americans. This is because
the IQ test is designed from a western
perspective. Western influences often emphasise
the importance of the individual, and not the
importance of teamwork, which is favoured in
other cultures
19The importance of cultural factors with
classification
- Rack (1982) found that rates of depression are
very low in Asian countries, which would suggest
that aetiological factors are restricted to
western cultures ? status anxiety? Too much
choice? - However, he realised that rates were actually
similar, but those in more eastern cultures are
more reluctant to seek help for depression due to
the stigma attached to depression as a mental
illness. In China, it was found that people only
went to seek help for mental disorder when the
symptoms are undeniably clear - Cochrane (197) discovered that black people were
between 2 and 7 times more likely to be admitted
to an institute with schizophrenia. If you were
white, you were also more likely to be admitted
with less severe symptoms. - Symptoms are more recognizable in white people so
they are more likely to be admitted early ? white
psychiatrists have similar cultural frames of
reference. - It could also relate to the access of healthcare.
There is less understanding because few doctors
are black/Asian. This could be due to social
drift ? when you slide down the social ladder
when youre mentally ill. People with a lower SES
are less likely to be registered with a GP.
Ethnic minority groups are usually lower un the
SES ? language problems?
20The importance of cultural factors with
classification
- Brislin (1993) thought that there are at least 3
possible ways in which culture influences
clinical conditions - The form the symptoms take (how they show
themselves) - Different cultures have different ways of
manifesting symptoms - E.g. 1920s ? schizophrenics heard voices through
the radio, 1950s ? they heard voices through the
TV, 1960s ? space, 1980s ? microwaves - Triggers (precipitatory factors) in different
societies are different - Haughton (1972) found that primitive African
tribes with problems would talk to a witch
doctor, who would try and find out who cast a
spell on them, Often illness was caused by
stress, so the poor relationships were improved,
therefore reliving stress - Prognosis in different cultures is different
- Kleinman Lin (1988) thought it would be better
to have schizophrenia in non-westernised
countries because the lifestyle is much simpler.
Non-westernised cultures have a higher emphasis
on family values, so there is less chance of
social isolation, and you can fit into society
better with their support - Self-worth ? can be low due to poor social
interaction, with which drugs cant helps
therefore there's lower self-worth in cultures
where society isolates those with mental problems
21The importance of cultural factors with
classification
- Culture bound syndromes
- When we define mental illness, its usually done
by a middle-class, white person, so anything
thats not usual to this culture will be ignored,
or unclassified, so they are often
under-diagnosed - Fernando (1991) thought that many illnesses
classified using western classification systems
dont recognize other forms of abnormality they
dont accept forms that go against the paradigm ?
ethno-centric bias - Some conditions are diagnosed more frequently in
one gender than another, which suggests a
gender-bias in diagnosis. - However, this could be due to the socialization
of women/men, and their willingness to see the
doctor. There may also be some genuine biological
factors in diagnosis - HISTRIORIC PERSONALITY DISORDER ? extrovert, OTT
associated with women, drama queen - DEPENDANT PERSONALITY DISORDER ? clingy,
attached associated with women - NARCISSISTIC PERSONALITY DISORDER ? Obsessive
vanity associated with men - OBSESSIVE COMPULSIVE DISORDER ? diagnosed more in
men - These prove how our socialized impressions of men
and women give us pre-conceptions of their roles.
Some of these conditions may be diagnosed if the
behaviour is away from our socialized norm
22The importance of cultural factors with
classification
- Too much emphasis on differences in cultures may
mean that if one culture suffers from a problem,
they will all be ignored ? its a part of their
culture, which could lead to under-diagnosis - However, there is an over-diagnosis in some
cultures (e.g. black people and schizophrenia) - With these problems its often easy to avoid the
importance of diagnosis
23Approaches clinical psychology
24Outline of biomedical approach
- Clinical conditions can be understood in the same
way as physical disorders. Emphasis on
biological/physiological explanations, e.g.,
genes, neurotransmitters (serotonin, dopamine
hypothesis, brain structure). - Focus is on physiological aspects of mental
disorder rather than behavioural, cognitive,
emotional or social aspects. - Clinical conditions can be treated physically
because they are physical in cause, I.e., through
chemotherapy (drugs), ECT, psychosurgery.
25Evaluation of biomedical model
- Evidence for biological explanations from twin
studies, e.g., Gottesman concordance for MZ
twins schizophrenia. Evidence for dopamine
hypothesis, serotonin levels in depression. - Biological treatments for clinical conditions can
be very effective, e.g., anti-depressants,
anti-psychotics, ECT for severe clinical
depression. - Side-effects of drug treatments, problems of
dependency. - Treats symptoms not underlying cause of problem.
- Problems of cause and effect, i.e., is
schizophrenia caused by too much dopamine or does
the condition itself lead to too much dopamine
being produced? I.e., behaviour may affect
biology, not the other way around. - Concept of no blame i.e., person cannot help
their condition because it is physical and beyond
their control BUT does this remove personal
responsibility from person with illness to the
health care professional. - Biomedical explanations ignore contributions made
by social psychological factors.
26Behavioural model
- Clinical disorders are explained as patterns of
learned maladaptive behaviour. - Focus is on observable behaviour as opposed to
physiological, emotional, cognitive or social
factors. - We learn maladaptive behaviours through processes
of classical and operant conditioning and social
learning theory. - Mental disorders can be treated using behavioural
therapies which aim to replace maladaptive
behaviour with adaptive behaviour through
classical operant conditioning e.g.,
flooding, aversion therapy, token economies.
27Evaluation of behavioural model
- There is lots of empirical evidence to support
the concepts behind behavioural model although
a lot of this research has been done on animals. - Behavioural techniques have proved effective in
treating some types of disorders, even some of
the behavioural aspects of schizophrenia. - Avoids labelling person, I.e, they have not got
an illness but maladaptive behaviour, it is the
behaviour, not the person, that is the problem. - This approach simply focuses on the outward
manifestation of the problem the behaviour, not
the underlying cause of this behaviour. This can
lead to symptom substitution where one symptom
or behaviour is treated but re-emerges or
manifests itself as another type of maladaptive
behaviour. - It underestimates the complexity of humans, we
are simply learning machines at the mercy of
our environment, cognitive factors (mental
processes) intervene between stimulus response. - It seems unlikely that complex clinical
conditions can be learned.
28The cognitive model
- This approach aims to explain specific features
of clinical conditions, rather than the illness
in its entirety, e.g., cognitive approach can
explain symptoms of schizophrenia such as thought
insertion, or poverty of speech thought - The cognitive approach focuses on cognitive
processes such as memory, distorted/irrational
thinking other perceptual problems, rather than
biological, behavioural, emotional or social
problems. - Cognition can affect physiological functioning
vice versa. - If symptoms of mental illness are cognitive in
nature, then treatment should involve tackling
cognition, i.e., challenging irrational beliefs,
distorted thinking. E.g., Ellis ABCDE paradigm
Aactivating experience Bbelief Cconsequences
DDisputing belief Eeffects of successfully
disputing belief. Becks cognitive
triadNegative view of self Negative view of
future Negative view of world - Beck argued that automatic negative thoughts
overwhelmed people with clinical problems. - Mental illness can be explained by negative
self-schemas which often develop early in
childhood. - The role of the cognitive therapist is to suggest
to the client new ways of interpreting situations
perceived as negative.
29Evaluation of cognitive model
- There is much scientific support for this
approach, e.g., Gustafson (1992) found that
maladaptive thinking processes were displayed in
many people with psychological disorders, such as
depression, anxiety sexual disorders. - There is also a lot of support for Becks
Elliss cognitive model of mental illness. - There is little empirical support for the concept
of schemas in relation to mental illness. - The cognitive model emphasises the role of
individual being self-sufficient (the
individual can almost think themselves better)
therefore, it tends to devalue social support
systems and places responsibility for issues
with the individual, not the social environment. - Cognitive-behavioural therapy has been shown to
be very effective with a range of disorders,
especially clinical depression, but also
schizophrenia. - Treatment, like the behaviourist approach, is
practical problem-solving in nature, but is
also empowering for the individual as they can
learn to control the excessively negative
thoughts emotions which can detrimentally
affect their lives. - Between 50-60 of depressed clients treated with
cognitive therapy show total remission of
symptoms (Hollon et al., 1993) - Improvements in self-concept produced by
cognitive therapy correlate with lifting of
depression (Pace Dixon, 1993). - However, the demand for cognitive therapy to
treat clinical depression often outstrips the
supply of trained psychology professionals. - Like the biological model there are problems with
cause effect, i.e., maladaptive thinking
processes may be the result and not the cause of
the psychological disorder, e.g., low serotonin
levels may lead to depressed thoughts, or
depressed thoughts may result in lower serotonin.
30The psychodynamic model
- The focus is on early relationships, especially
with parents, and how this can affect mental
health well-being in later adult life. - Early traumatic experiences are associated with
later mental health problems. - These early experiences are retained in our
unconscious mind affect our later conscious
feelings, motives relationships. - We often use defence mechanisms to prevent use
from confronting these traumatic experiences,
which often result from conflicts between the
demands of the id, ego superego. - Freud used the term hydraulic model to explain
his concept of personality we often bury trauma,
conflict repressed emotions but this can lead
to a build up of pressure (hence term hydraulic)
tension which needs to be vented in some way,
I.e., we have to figuratively blow off steam in
some way. - Treatment involves uncovering these unconscious
elements through psychoanalysis in order to
achieve catharsis the safe release of this
unconscious tension/psychic energy.
31Evaluation of the psychodynamic model
- Some aspects of Freudian theory have support,
especially notion of importance of early
childhood experience, e.g., Brown Harris. - However, many other aspects of theory have little
scientific support are difficult to test
empirically because they are subjective revolve
around the unconscious (NB., just because
something cannot be scientifically tested does
not mean it is not necessarily correct.) - Freuds theory was based on a limited atypical
sample. - Freud was instrumental in changing the way we
think about mental illness and psychoanalysis
(and Brief Dynamic Therapy) have been shown to be
effective in treating some forms of mental
illness (and are better than treatment at all). - Psychoanalysis can take months or even years, and
therefore can be expensive.
32The Humanistic Model
- People have a basic tendency to grow fulfil
their potential to self-actualise - Problems arise when a person cannot realise their
full potential and is prevented from doing so
because of the demands/constraints of society
family etc. People cannot self-actualise because
they make personally inappropriate life-choices
which prevent them from exercising their
potential being true to themselves. - Where incongruence exists, a large gap between
self-concept and ideal self, a lack of
self-esteem can result and this can prevent an
individual from making life choices that they
want to. Incongruence can result through a lack
of unconditional positive regard and a sense of
doing things to get positive regard from others. - Hence there is a strong association between
mental health and having a healthy self-image and
strong sense of self-esteem. - The primary concern of this approach, like the
psychodynamic approach, is on emotion, as opposed
to biology, cognition or behaviour. - People are essentially future-orientated, and
under the right circumstances will make the best
choices for themselves. The aim of this approach
is to help people make the right choices and so
fulfil their human potential. Therapists
(practising person-centred therapy) need to
exhibit three core characteristics to help their
clients achieve this Empathy, Congruence/Genuinen
ess, Unconditional Positive Regard/Non-Judgemental
.
33Evaluation of the Humanistic model
- Numerous studies have supported a link between
parenting style, self-esteem and mental health.
Research has shown that children with higher
self-esteem have improved self-concept which has
also been associated with greater achievement (or
actualisation). Lau Pun, 1999 Burnett,
1999. - However, it is generally argued that the
humanistic approach does not lend itself to
scientific (empirical) research easily, thus the
scientific evidence supporting this approach can
be limited. - Related to the above point, the concepts in the
humanistic approach, e.g., self-actualisation
self-concept, can be quite vague/nebulous and
subjective, making them hard to quantify and
measure objectively (key features of scientific
study). - Many people never self-actualise but still some
to be perfectly happy. - Person-centred therapy, with its emphasis on
personal growth, rather than illness, avoids the
problem of labelling or stigmatising an
individual. However, it has been argued that
this approach is often overly optimistic about
the human condition and experience. It is also a
reflection of the American culture it emerged
from, i.e., it focuses on the individual which
may be a good thing in some respects but it
disregards social and environmental factors which
may be beyond the control of the individual,
e.g., jobs, housing. - The humanistic approach requires a certain amount
of personal insight, in order to be able to talk
about ones own experiences and choices in many
cases people suffering from more profound
clinical condition have limited or no insight
into their condition. - Person-centred therapy concentrates on the
individual not the problem. However, while this
might be a good thing most of the time, there are
some situations where the problem may need
addressing, e.g., a neurochcemical imbalance. - Rogers did not explain in the same detail as
alternative theories, e.g., cognitive, social
learning theory, exactly how parenting,
self-esteem and mental health are linked. - This apporach may be useful for people to whom
spirituality is important.
34The Social Model
- The development of diagnostic categories, such as
schizophrenia, anxiety disorders, affective
disorders, and the actual process of diagnosis is
rooted in social processes, e.g., making
judgements about what is and is not abnormal. - Social factors, such as poor relationships
family communication (expressed emotion), low
socio-economic status related issues, may
predispose or precipitate a clinical problem. - The emphasis is on social explanations of
disorders rather than on individual emotional
experiences, or other psychological biological
factors. E.g., feminists emphasise the role of
the relative social power of ment women in the
development of mental disorders in women. - Clinical problems can be treated using social, as
well as psychological biological interventions.
E.g., care-in-the community programmes, drop-in
centres, social skills training and help with
day-to-day living. - Traditionally people suffering from mental health
problems where placed in mental institutions,
where, as Goffman (1968) argues, they would be
subject to social control and become
institutionalised. - R.D. Laing famously suggested mental illness was
a fairly rational response to the sense of
alienation felt by many and to the intense
pressure of family life society people are
obsessed with maintaining the status quo and
strive to maintain their own definition of
reality Madness need not be breakdownit may
also be breakthrough - Thomas Szasz, The Myth of Mental Illness, argued
that mental illness is better viewed as a problem
in living, which is socially expressed, rather
than an mental illness he argued against the
medicalisation of what he regarded as
essentially social problems. He suggested
clinical diagnosis is a form of symbolic
recapture, where society tries to predict an
individuals behaviour, yet because mentally ill
people are unpredictable society tries to label
stigmatise such people in order to make them more
controllable, I.e., they are hospitalised or
given chemotherapy to make them more pliable and
predictable.
35Evaluation of the Social Model
- Social explanations provide a contrast with the
individual explanations offered by other
biological psychological perspectives. - There is some evidence to suggest a link between
social factors, e.g., social relationships
socio-economic status and mental illness, e.g.,
Brown Harris (1978) Expressed emotion and
rates of relapse for schizophrenia (Brown, 1973)
NB., this only supports factors to do with
relapse and not causation. - Consider evidence for against social drift
social causation as explanations of clinical
disorders. - Care-in-the-community is seen as a better, more
effective and ethical treatment of mental illness
than other treatments, such as hospitalisation
and chemotherapy, as it avoids the problems
associated with institutionalisation and
subsequent labelling and stigmatisation and the
problems of dependency and side effects of some
drug therapies. Patients in care-in-the-community
programmes are often happier and make better
progress than long-term hospitalised patients
(Hogarty, 1993). Care-in-the-community allows
patients to retain family friendship ties
support more easily. - However, care-in-the community programmes,
drop-in centres, 24 hour helplines etc.are often
not well-funded (mental illness is often not seen
as a funding priority), or coordinated and there
is often a lack of expert/skilled mental health
practitioners available. - If the social environment is the cause of the
problem and cannot be influenced then other forms
of treatment might be more effective. - Evidence shows that the supportive atmosphere of
half-way houses aids recovery from schizophrenia. - Lack of continuity in who deals with patient may
lead to problems. - If patients are in the community it may be more
difficult to ensure compliance with drug
therapies due to lack of control. This can in
turn lead to the revolving door syndrome. - The presence of support in the community does not
mean patients will use it. - Social explanations are often regarded as merely
incidental to, or amplifications of other
biological/psychological explanations, not as
explanations in themselves (per se). They are
usually incorporated into a diatheis-stress
explanation of mental illness (I.e, there is an
underlying biological or psychological cause
which requires some kind of external/social
trigger in order for the disorder to manifest
itself and develop.
36Therapies Treatment
- The Medical Model
- This states the idea that mental problems are
caused by physical malfunctions ? treatment must
be physical also - Psycho-surgery
- Surgical processes to alter psychological
malfunction - Freeman and Watts (1942) developed modern frontal
lobotomy, but lack of scientific nature,
unpredictability and its side effects meant that
it was not done - Psycho-surgery is now used, and is treatment for
conditions like OCD, depression and violent
behaviour
37Therapies Treatment
- Chemotherapy
- Use of drugs to treat psychological conditions
- Used to treat schizophrenia and steroid abuse
- Drugs are used to block dopamine receptors
(post-synaptic sites) in the brain - SSRI Serotonin levels are affected to treat
depression - They often have unpleasant side effects
- With drugs theres often a strong chance of
relapse - They can take up to 4 weeks to work
- Electronic Compulsive Therapy (ECD)
- Electrodes are attached at 110V for 30s 4 mins
through temples - Treats depression, bipolar disorder and OCD
- Used on 20,000 people p.y
- Much quicker than drugs therapy
- High success rate, but the treatment is very
unpleasant
38Therapies Treatment
- The Social Approach
- Community Psychology
- Good mental health from correct interaction with
community environment - Against institutionalisation because it prevents
people from interacting with others in a normal
way ? we shouldnt marginalize people - Emphasises the environment as the cause and
treatment from mental problems - Half-way houses
- A good way of receiving support and treatment,
without becoming institutionalised - Home care
- They can remain with their families, and still
receive treatment - But this can cause pressure for the family, and
may cause stress ? more problems develop - 24-hour care
- A telephone service that allows people to have
someone to talk to all the time - ST Inpatient care
- A drop-in program in hospitals for mental
health care
39Therapies Treatment
- The Cognitive Approach
- Believes that mental problems come from
maladapted thought processes - Aim is to change self-defeating assumptions
- Rational-emotive therapy
- To find flaws in their thinking, and break the
cycle of poor thinking - Attribution Therapy
- Finds the flaws in attributive thinking ?
internalising things can cause distress - Cognitive behavioural therapy
- Change behaviour through changing thinking about
that behaviour - Self-efficacy
- We look at other people and believe that we can
do something
40Therapies Treatment
- The Humanistic Approach
- Believe that mental problems stem from issues
with personal growth - This approach focuses more on the individual, and
their view on the world - Therapists needs to act genuinely, and with
unconditional positive regard, as well as
accurate, empathic understanding - Self-actualisation is important ? being able to
focus on the present and the goals in life - The emphasis needs to be on freewill etc. to
develop p. growth, so structure needs to be free - Existential Therapy
- logo therapy for those with anxiety disorders
and phobias - If you can wish the worst case of your fear upon
yourself, then you cannot over-anticipate the
problem - Client-centred therapy
- Healthy people are aware of behaviour, and are
good and centre effective - Therapist will give the opportunity for these
things to happen - It relies on the assumption that people are
essentially good
41Therapies Treatment
- The psycho-dynamic Approach
- Hypnosis
- Although Freud did not agree with hypnosis, it is
believed that it can help to uncover thoughts
from the unconscious - Free association
- The ego acts as a censor to the information, so
free association can get past this by not
allowing the ego to cover information before it
leaves the unconscious - This is the most widely used therapy
- Dream interpretation
- The dreams offer a solution in terms of dreams
being unconscious wish fulfilment - They can help offer information from the
unconscious
42Therapies Treatment
- The Behavioural Approach
- Shaping
- Rewarding behaviour as it gets closer to the
desired outcome - Can be used to improve social interaction in
autistic children and schizophrenics - TEP
- Tokens act as secondary reinforcers, and research
has proven that both animals and humans will
continue behaviour for reinforcement at a later
time - It has been proved useful in personal care and
social development, particularly in institutional
environments - However, it can make participants dependant on
tokens - Aversion Therapy
- Works by associating negative stimuli with a new
response - Uses the principles of classical conditioning
- E.g. alcohol with vomiting ? vomiting negative ?
drinking negative
43Summary Medical
- Allows research to be carried out ? animal/twin
studies - The fact theyre treated with drugs means the
cause must be biological
- Treats the symptoms and not the cause
- Cause and effect ? circular arguments (symptoms
cause condition or condition cause symptoms?) - Medical label stigmatises them ? used as an
excuse because it removes responsibility
44Summary Behavioural
- Allows to treat behaviour, not label the person
- Scientific ? research can be carried out, and can
be falsified
- Animal experiments are hard to generalize to
humans - Treats the symptoms and not the cause
- Symptom substitution ? the real cause will emerge
later in other forms - Ethical concerns about reconstructing behaviour
to fit in with social norms
45Summary Cognitive
- Lots of scientific research
- Can be tested and retested
- Focuses on the individual
- Problem solving and practical
- Ignores social factors, and may convince people
that they can think themselves better
Cognitive therapy and behaviour therapy can
combine to make a more effective treatment
46Summary Psycho-dynamic
- Despite not being proven, it can still work and
has been proved to be effective in some cases
- Retrospective ? need to look at the past before
resolving problem so it lacks predictive validity
47Summary Humanistic
- Too optimistic about human nature
- Too reliant on personal growth ? some people with
depression appear to have everything they want
but are still unhappy ? too materialistic - Not scientific
- Not empirically testable ? cannot observe things
like self-actualisation
48Summary Social
- Helps people live better together
- Combines with medication to help solve problems ?
needs social skills to integrate
- Very difficult to get trained professionals ?
expensive - Families can be a part of the problem!
49Effectiveness of Therapies
- Judged on
- Observation of behaviour
- Recidivism how often people have to go back for
treatment - Self-report
- Meta-analysis look at other research to find a
trend - Smith (1980) found that all therapies worked, but
May found that chemotherapy works the best. - Its found that experienced therapists are better
than less experienced therapists ? the therapies
must help - This is because experienced therapists adopt a
multi-model approach bio psychosocial - People who arent qualified, yet have good
personal skills can be just as effective ?
psycho-therapies (talking) are merely placebo
50Clinical Conditions
- Schizophrenia
- The fragmentation of personality not different
personalities - 5 types
- Disorganized Schizophrenia
- Speech/behaviour is disorganized
- Neologisms made-up words
- Word salad mixed-up words in sentences
- Thought-blocking
- Personal hygiene affected
- Catatonic Schizophrenia
- Alternating between high excitement and immovable
state (catatonic state) ? one of these states
may dominate - Inappropriate emotional responses
- Flattening affect (bluntening of emotion)
- waxy movement 0 can move a limb and it would
stay there
51Clinical Conditions
- Schizophrenia
- Paranoid Schizophrenia
- Hallucinations
- Delusional thinking (of grandiose, prowess etc)
- Not disorganized
- Undifferentiated schizophrenia
- Patient has symptoms from all forms of
schizophrenia - Not clearly categorized
- Residual Schizophrenia
- Some signs still remain, but not overtly
schizophrenic - Reliability
- Hard to categorize people with all the different
symptoms - Harder to have predictive validity ? prognosis
would be different for sub-types, and the patient
may show signs of more than one type
52Clinical Conditions
- Schizophrenia
- There is another method of classification
- Positive Schizophrenia
- When things are added to the personality e.g.
delusions - Associated with dopamine receptors
- Negative schizophrenia
- When things are taken away e.g. flattened
emotions - Associated with structural abnormalities of the
brain (bigger ventricles) - Positive schizophrenia can also be sub-divided
- Delusions and hallucinations
- Disorganized behaviour
53Clinical Conditions
- Schizophrenia
- Causes Biological
- Genetic Causes
- Family Studies
- Children of 2 schizophrenic parents have 46
chance of inheriting schizophrenia - This may also be due to environmental learning
- Twin Studies
- Gottesman (1991) believed MZ twins had 48
concordance, whereas this is only 17 in DZ twins
(concordance relates to both twins getting the
disorder) - However, identical twins also share very similar
environments - Biological Causes
- Chemicals
- One theory is that dopamine is over-active in the
synapses, which may explain type one positive
symptoms of schizophrenia - Symptoms of acute paranoid schizophrenia are
similar to those of amphetamine psychosis, which
is caused by amphetamines over stimulating
dopamine receptors - Anti-schizophrenic drugs (e.g. chlorpromazine)
work by blocking post-synaptic receptors sites
for dopamine, reducing its activity. - Post-mortems and PET scans have found more
dopamine and dopamine receptor sites in
schizophrenics - However, the dopamine hypothesis may be an
over-simplified account of schizophrenia new
schizophrenia drugs work by affecting other
neurotransmitters, like Serotonin
54Clinical Conditions
- Schizophrenia
- Causes Biological
- Biological Causes
- Brain structural causes
- Enlarged ventricles are fluid filled cavities in
the brain. Reserch has found that these are
larger in schizophrenics due to brain cell loss.
Cell loss in the temporal lobes of the brain
(cognitive and emotional functions) have been
associated with negative symptoms. However, this
may be a symptom, and not a cause - Brain area activity is also found to be different
for schizophrenics. When given problem solving
activities, schizophrenics brain scans have shown
unusual prefrontal activation of the cortex.
This method cannot yet predict the presence of
schizophrenia.
55Clinical Conditions
- Schizophrenia
- Causes Psychological
- Psychodynamic
- Freud argued that schizophrenia could be due to
regression to a state of narcissism in the early
oral stage, where no ego is developed to test
reality. Psychotic thoughts are similar to those
irrational thoughts first presented by the id.
Psycho-analysis would not help treat this
condition because a patient in psychosis does not
have the necessary attachment to reality. - Existential
- The idea that people withdraw from reality as a
response to the pressures of life becoming
unbearable (Laing) - Some psychiatrists believe that this can be a
positive journey of self-discovery - Labelling theory
- Scheff (1966) argues that schizophrenia, once
diagnosed, becomes a self-fulfilling prophecy. - The reactions of other people in society become
internalised, and help reinforce the idea - Szasz takes this idea further, and believes we
create the label schizophrenia to control people
who are different as a form of social control - Cognitive theory
- Frith (1979) believed that there was problems
with short-term memory and the brains capacity
for information with schizophrenics. An
attentional-filter mechanism in the brain means
that information going into the brain overloads
sufferers from schizophrenia, causing the
cognitive distractibility
56Clinical Conditions
- Schizophrenia
- Causes psychological
- Social factors
- Family stresses
- Reichmann proposed the idea of a
schizophrenogenic mother who can aggravate
symptoms of schizophrenia - Also, in families where the is a high amount of
expressed emotion, symptoms seem to develop more
frequently in people prone to schizophrenia - However, this research is correlational, so
perhaps the schizophrenia causes the stress and
not vice versa - Environmental stresses
- Schizophrenia is found to be 8x more likely in
families of a lower social-economic status - However, this could be a cause, or an effect of
the social drift with people with schizophrenia - Viruses
- Viruses may also trigger schizophrenia (e.g.
influenza) - This can be particularly important during the
pregnancy, when there can be damage to the
placenta
57Clinical Conditions
- Depression
- Unipolar depression has a prevalence rate of 5,
and occurs twice as often in men as in women - It can be affected by age, gender, social class
and marital status - Symptoms Unipolar
- Emotional
- intense feelings of sadness or guilt
- lack of enjoyment of pleasure in things
previously enjoyed - Cognitive
- frequent negative thoughts
- faulty attribution of blame (blaming themselves)
- Motivational
- passivity
- difficulty in making and initiating decisions
- Somatic
- Loss of energy or restlessness
- disturbance of appetite, weight and sleep
58Clinical Conditions
- Depression
- Bipolar depression is less common as Unipolar
- It involves the symptoms of Unipolar depression,
combined with mania or hypomania - There is around a 1 prevalence of bipolar
disorder - Symptoms Bipolar
- Emotional
- Abnormally euphoric elevated or irritable mood
- increased pleasure in activities
59Clinical Conditions
- Depression
- Symptoms (Bipolar)
- Motivational
- increase in goal-directed activity
- increase in pleasurable activities with a high
risk of danger - Cognitive
- inflated self-esteem or grandiose
- racing ideas and thoughts
- distractib
