Psychology Revision
  • Clinical Psychology

2
What 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)

3
What 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.

4
What 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

5
What 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

6
Problems 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

7
Classification 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

8
Validity
  • 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

9
Validity
  • 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

10
Reliability
  • 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

11
Reliability
  • 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)

12
Interviews
  • 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.)

13
Classification 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

14
Classification 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

15
Classification 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

16
International 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

17
Diagnostic 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.

18
Cultural 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

19
The 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?

20
The 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

21
The 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

22
The 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

23
Approaches clinical psychology
  • The Biomedical Model

24
Outline 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.

25
Evaluation 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.

26
Behavioural 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.

27
Evaluation 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.

28
The 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.

29
Evaluation 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.

30
The 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.

31
Evaluation 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.

32
The 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
    .

33
Evaluation 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.

34
The 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.

35
Evaluation 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.

36
Therapies 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

37
Therapies 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

38
Therapies 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

39
Therapies 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

40
Therapies 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

41
Therapies 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

42
Therapies 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

43
Summary 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

44
Summary 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

45
Summary 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
46
Summary 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

47
Summary 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

48
Summary 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!

49
Effectiveness 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

50
Clinical 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

51
Clinical 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

52
Clinical 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

53
Clinical 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

54
Clinical 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.

55
Clinical 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

56
Clinical 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

57
Clinical 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

58
Clinical 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

59
Clinical 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
