Definitions of abnormalitySlide3

Deviation from Social Norms

Norms are the way that the majority are expected to behave in society.

Those that do not think or act the same as others in society break the norms, and are therefore deemed abnormal.

The definition is based on the fact that abnormal behaviour is ‘vivid and unpredictable, violating moral and ideal standards’ (

Rosenhan

and Seligman, 1987)

Change over time: social norms change as social attitudes change.For example the wearing of trousers by women.

Human rights abuse: this definition has been used to abuse human rights, for example, the term ‘mental illness’ is a form of social control.

Cultural

relativism: social norms vary within and between cultures. Sometimes it is difficult to tell what is actually abnormalSlide4

Failure to Function Adequately

Failing to function adequately = not being able to cope with day-to-day activities.

Peoples’ behaviour is considered abnormal when it begins to cause torment or distress.

The more of these key terms you experience, the more abnormal you are...

Maladaptive behaviour

Personal distress

Irrational behaviourUnpredictable behaviourObserver discomfortViolation of moral and ideal standards

Violation of moral and ideal standards

Any behaviour that doesn’t fit with society’s standards

Observer discomfort

Any behaviour which causes distress in others (e.g. family or friends)

Unpredictable behaviour

Behaviour you would not expect in a set of circumstances

Irrational behaviour

Any behaviour without a rational explanation

Personal distress

E.g. experiencing depression or anxiety would cause distress to the individual

Maladaptive behaviour

Behaviour that stops you achieving your goals

Cultural

relativism:

Day-to-day tasks are set by the culture in which you live.

Applying these criteria to people outside of our culture increases rates of abnormality.

This explains why non-white, non-middle class individuals often diagnosed as mentally ill.

Someone needs to decide if someone else is failing to function adequately, or not managing day-to-day tasks. This might be the patient who realises they are distressed. Other times this is a doctor who notices that someone is not coping wellSlide5

Deviation from Ideal Mental Health

This definition is the only one which outlines ‘normality’.

Marie

Jahoda

(1958) outlined 6 criteria necessary for ideal mental health; the more you have, the more normal you are.

She compared mental health to physical health in terms of the criteria needed to withstand illness.

These criteria are…

Is mental health the same as physical health? If we use these criteria to detect mental illness in the same way as physical illness, then we are likely to make misdiagnoses.

Not everyone can achieve all the criteria

Cultural relativism: Criteria for ideal mental health are culture-bound. This means that they match the Western cultures, but cannot apply to everyone. Slide6

Biological approaches to psychopathology

Abnormal behaviours result from physical problems and should be treated medically.

Mental illness is of a similar nature to physical illness – both are characterised by a particular set of symptoms, which will match up with a diagnosis of a particular condition. The condition can then be treated appropriately.

Just as physical illnesses are caused by disease producing germs, genetic factors, biochemical imbalances, or changes to the nervous system, it is assumed that this is also true for mental illnesses.Slide7

Limitations of the biological approach

Does excess dopamine cause schizophrenia, or does schizophrenia cause low dopamine

?

In the 18

th

century the medical model lead to a more humane form of treatment (before this demons were blamed). Now the illness was seen as potentially treatable. Some say that the medical model is inhumane.

Szasz

(1972) said that not all mental illnesses have a physical basis, and should not be thought of in the same way. He suggests that mental illness was invented as a form of social control.

Schizophrenia is associated with excess dopamine. However some schizophrenics actually have lower levels in some brain levels. Maybe there are simultaneous low and high levels.

No 100% concordance rates. Gottesman and Shields (1976) reviewed 5 twin studies looking at schizophrenia. MZ twins = 50% so schizophrenia is not a result of genetic inheritance. Maybe we inherit a susceptibility and exposure to life conditions could lead to the disorder (diathesis-stress model).Slide8

Psychological approaches to psychopathology (psychodynamic)

Abnormal behaviour could be due to the id (the innate ‘pleasure’ principle) seeking immediate satisfaction.

Abnormal behaviour could be due to the overuse of ego defence mechanisms. The superego (moral principle) develops at age 5 and is in conflict with the id. The ego (reality principle) tries to help the individual cope with the demands of daily life and uses mechanisms such as repression, denial, or regression.

Abnormal behaviour could be due to fixation at one of the stages of development (e.g. anal stage = OCD, or oral stage = eating disorders).

Finally, early childhood experiences can lead to abnormality. Freud believed that early loss or abuse could lead to depression.Slide9

Limitations of the psychodynamic approach

The model has an over-emphasis on childhood influences and ignores everyday problems in adult life.

It is difficult to validate the theory – it cannot be scientifically tested.

It is difficult to find evidence for the id, ego, and superego; after all, they are in the unconscious.

The model is ‘

unfalsifiable

’; if an analyst uncovers something from childhood, this is said to have an influence on adult life. However, if no such childhood event is uncovered, then the child has been traumatised by the event and it remains hidden!The model is dominated by case studies and these are unscientific.Evidence collected by therapists is subjective and biased.Freud’s patients were mainly Viennese, middle-class women – can the findings be generalised?

There is an over-emphasis on sexual factors being the influence of abnormal behaviour. Now social relationships are seen as important, perhaps inadequate social relationships can cause sexual problems.Individuals are not to blame for their behaviour, parents are

!Slide10

Psychological approaches to psychopathology (behavioural)

All

behaviour is learned whether it is normal or abnormal.

The

emphasis of this approach is on the environment and it ignores the role of biology or of any internal thoughts or feelings.

The

learning can take one of three forms: Slide11

Limitations of the behavioural approach

The approach is limited.

The approach ignores the role of biology.

Research is based on animal learning.

The approach

ignores the role of

cognition; it only focuses on the symptoms and not the cause of abnormal behaviour. The problem with these theories is that many people do not know the source of their phobia, and it is supposed to be traumatising in some way.Seligman

(1970) provided an explanation of why people rarely mention phobias of fast moving objects like cars, suggesting that basic anxieties are hard-wired into our brains from ancestors. Therefore we are prepared for small and fast moving animals, but not cars.Behavioural

therapies are effective, but not long-lasting. Symptoms are just the tip of the iceberg and we are not treating the cause, symptoms resurface (symptom substitution). Maybe the symptoms are behavioural but the cause is not.Slide12

Psychological approaches to psychopathology (cognitive)

The cognitive approach believes that abnormality stems from faulty cognitions about others, our world and us.

This faulty thinking may be through cognitive deficiencies (lack of planning) or cognitive distortions (processing information inaccurately).

These cognitions cause distortions in the way we see things; Ellis suggested it is through irrational thinking.Slide13

Limitations of the cognitive approach

Situational factors of the abnormal behaviour may be ignored because the cognitive model assumes the individual’s thinking to be of fault.

The disorder is thought to be in the patient’s mind rather than due to the individual’s environment

.

Biological factors are ignored.

The individual is blamed for their faulty thinking.

It is not clear what comes first, the illness or the thinking. Do thoughts and beliefs cause disturbance, or does the mental disorder cause the faulty thinking?Faulty thinking may be a vulnerability factor for abnormality. People with maladaptive cognitive processes are at a greater risk of developing mental disorders.Alloy and Abrahmson

(1979) suggest that depressive people tend to see things as they really are (rather than normal people seeing the world through rose-tinted glasses)Depressed people give more accurate estimates of the likelihood of a disaster than ‘normal controls’ and call this the ‘sadder but wiser’ effectSlide14

Biological therapies (

drugs)Slide15

Biological therapies (ECT)

Electrodes are placed on the temple of the non-dominant side of the brain and on the

forehead.

Patients are injected to make them unconscious and given a muscle relaxing agent, patients are given oxygen due to their inability to

breathe.

Electric

current of 0.6 amps (lasting half a second) is passed through the brain, this current produces a seizure lasting about a minute.ECT is given 3 times a week for 3-15 sessions.

Not sure why it works.ECT causes changes to the brain but we’re not sure how.Slide16

Evaluation of biological therapies

Drugs

ECT

Strengths

Cheap and easy to take.

Little effort needed.

WHO (2001) reported relapse to be highest when taking a placebo (55%) and lowest when drug was taken combined with family intervention (2-3%).

Antipsychotics work (66%)

Saves livesEffective for severe depression when other techniques fail

Comer (2002) states that 60-70% of ECT patients improve after treatmentSackheim et al (2001) found 84% of patients relapse within 6 months (i.e. not long term)LimitationsKirsch et al (2002) reviewed 38 antidepressant studies and found placebos to fare almost as well as real drugs.

Tackles the symptoms and not the cause.As soon as the drug is stopped the patient returns to old state.

Side effects of drugs: SSRIs (anxiety, sexual dysfunctional, insomnia, nausea and suicidal thoughts).

1998 Donald Schell, 60, killed his wife, daughter, granddaughter and himself two days after starting SSRIs.

Patients who received ‘sham’ ECT (ECT procedure with no electric current) recovered. So maybe the attention received helps too

Side effects of ECT: memory loss, cardiovascular changes and headaches

DOH report (1999) found many suffered long term fear and anxiety

Slide17

Psychological therapies (psychoanalysis)Slide18

Evaluation of psychoanalysis

limitations

There are issues with Freud’s theory of personality, this then means that these arise in therapy too.

Freud tried to fit his theories to the individual. Modern humanistic or person-centred therapies put the client first, rather than imposing theories on them.

Therapy

is very time-consuming and is unlikely to provide answers quickly.

People must be prepared to invest a lot of time and money into the therapy; they must be motivated.They might discover some painful and unpleasant memories that had been repressed, which causes them more distress.This

type of therapy does not work for all people and for all types of disorders.strengths

Bergin (1971) analysed 10000 patient histories and estimated that 80% benefitted from psychoanalysis. It seems that the length and intensity of the treatment leads to recovery.Tschuschke et al (2007) carried out a long-term study of 450 patients and found the longer the treatment the better the outcome.Slide19

Psychological therapies (systematic desensitisation)

The subject is given training in muscle relaxation

techniques.

A hierarchy of fear is drawn up; this is a list of fearful situations, real or imagined, and the subject lists them in order of least to most

fearful.

The subject uses the relaxation techniques at each stage of the hierarchy; starting with the least fearful situation and progressing onto the next stage when the subject feels sufficiently able to do

so.Slide20

Evaluation of behavioural therapies

Strengths

Quick

Requires little effort

Can be the only treatments for some groups, e.g. those with learning difficulties

Can be self-administered with computer programmes

Very successful with phobias, 75% success rate (McGrath et al, 1990)Capafóns et al (1998) found that SD reduced a fear of flying

LimitationsThe symptoms may be repressed but other symptoms may appear (symptom substitution). But

Langevin (1993) claims that there is no evidence to support this claim.Öhman et al (1975) suggest that SD may not be as effective at treating evolutionary adaptations, e.g. fear of the dark, heights etc. This is because they helped our ancestors to survive.It may work in a lab but not in the real world.It relies too much on the patient imagining the fearful scenario.Slide21

Psychological therapies (CBT)

The focus is on the ‘B’ of the ABC

model to change irrational beliefs

The

techniques used in cognitive-behavioural therapy include:

Challenging the clients’ thoughts and asking them to prove the accuracy of their beliefs (logical disputing)Self-instruction

or self-talking (e.g. “thought-stopping”). This is pragmatic disputing .Teaching the client ways of acquiring coping strategies (the behavioural elementof the therapy

).Slide22

Evaluation of cognitive therapies

Strengths

In a meta-analysis of 28 studies Engels et al (1993) found that CBT is effective for a range of disorders (OCD and social phobias).

CBT is more effective than SD or a combination of other therapies.

Not only useful for people suffering from mental disorders or phobias, but also non-clinical populations (exam anxiety).

Yoichi et al (2002) found that CBT could be administered on a computer programme. The sessions lasts 50 minutes, and is based on the A-B-C as well as homework. The homework is to get the client to think about the advantages and disadvantages of irrational beliefs. This lead to a decrease in anxiety.

Limitations

Fails to address the issue beyond the irrational environment, e.g. bullying partners or jobs with critical bosses. So the environment continues to produce irrational thoughts and maladaptive behaviours.

CBT doesn’t always work.Sometimes people do not do as they are told and out it into action.

Some do not listen to the advice of the practitioner.
