DSM-IV-TR CRITERIA for specific phobia • Marked and persistent fear that is excessive or unreasonable. • Exposure to the phobic stimulus almost invariably provokes an immediate anxiety response such as a panic attack. • The person recognises that the fear is excessive or unreasonable. This feature may be absent in children. • The phobic situation is avoided or endured with intense anxiety or distress. • The avoidance, anxious anticipation, or distress in the feared situation interferes significantly with the person’s normal routine. • In individuals under age 18 years the duration is at least six months. • The anxiety, panic attacks or phobic avoidance is not better accounted for by another mental disorder, such as OCD Reduce ?

4. Phobia The DSM identifies clinical characteristics that differentiate between a clinical phobia and a mere fear.Firstly the individual must recognise that their behaviour is irrational but continue to act in that way. Secondly the phobia must encroach on everyday life, interfering with their day to day, normal activities, such as going out in public. Moreover the individual suffering from the phobic disorder will not feel in control of their actions and the anxiety associated with the disorder will have a substantial longevity – in children the disorder must have lasted for at least 6 months. Lastly panic attacks may accompany the phobia, especially when the individual is presented with situational cues of the phobia or comes into direct contact with it – this especially will lead to irrational behaviour and often crying in children . 132 words (100 words for 4 marks) Detailed and accurate = 4 out of 4 marks

15. ‘In an important and influential criticism of the diagnosis of mental illness, Rosenhan (1973) showed that healthy ‘pseudopatients’ could gain admission to psychiatric hospital by pretending to have auditory hallucinations. Although systems of classification and diagnosis have changed considerably since the 1970s, many people still have concerns about their accuracy and appropriateness.’ Discuss issues surrounding the classification and diagnosis of schizophrenia. (8 marks + 16 marks) There are two types of classification system. The first is the DSM, Diagnosis and Statistical Manual of mental disorders. The DSM was published in America so is only available in English. This therefore means that the rest of the world are unable to use this classification system. The DSM is used now as the 4th edition as the first editions were simplistic and vague. The DSM consists of 8 categories which 42 mental disorders fit into. The second classification system is the ICD International Classification system of mental disorders. This was first published by the WHO in 1990 so it is available world wide for all patients. The ICD is thought to be a better classification system as it is available world wide so isn’t culturally biased. It also diagnoses people with symptoms after seven months while the DSM does after 12. Lastly more people can be fitted into the ICD classification system as it has seven subtypes while the DSM has five.

16. It is very easy to misdiagnose people with schizophrenia or it is difficult to tell where the normal behaviour starts and the abnormal ends. There have been many cases of misdiagnosis . Diagnosis is the classification and identification of a disorder in terms of its signs and symptoms. Signs are objective tests such as blood tests and symptoms are reports from patients. A famous case of misdiagnosis when a group of psychologists pretended to be mentally unstable to be admitted into a mental hospital. Once they were admitted they then acted normally and thought the staff would see they were medically sound and let them out. This didn’t happen as the staff believed what they were doing wasn’t right i.e. saying they were sane! After a while and after many letters were sent, the psychologists were let out. Another case of misdiagnosis was found by a psychologist in the 1960s. He found that there was a significant rise in the amount of people with catatonic schizophrenia. This type of schizophrenia is defined by muscle abnormalities. He then found that sleeping sickness had similar characteristics to this type of schizophrenia so people were being wrongly diagnosed. Another reason why people are misdiagnosed is down to cultural differences. In some countries schizophrenia is seen as a good thing whereas in England and similar cultures it is seen as different leading to different treatment of people.

17. A reason why it is hard to diagnose people with schizophrenia is that it is difficult to put people into the subtypes. This is because of individual differences, as some people may have symptoms of more than one subtype of schizophrenia. This is due to schizophrenia being heterogenous, the ability to be linked to other disorders. Schizophrenia is mainly linked to depression, which is why the treatments for the two disorders are similar. A way the classification systems overcame diagnosis is making it multi-racial. This means that the doctor has to assess 5 different areas before diagnosing the patient. In evaluation, since 1970 there have been many improvements made on the classification and diagnosis of schizophrenia. There have been many improvements yet still many faults in the systems. For example individual and cultural differences are still not taken into account. A psychologist found more cases of schizophrenia in African and Caribbean cultures than European countries. There are still many areas of misdiagnosis of schizophrenia as it is still a fairly new mental disorder. So although improvements have been made since 1970 there is still a long way to go until the classification systems are flawless and there are no more cases of misdiagnosis. 600 words

39. Outline and evaluate one biological therapy for schizophrenia and one psychological therapy for schizophrenia. (8 marks + 16 marks) One biological therapy used for schizophrenia is the use of drugs. A schizophrenia patient is likely to have hallucinations and other delusions, 73% of schizophrenics do. Research findings indicate that the cause of this is too much dopamine in the brain that the individual cannot deal with. The drug that the patient takes blocks some of the dopamine receptors and therefore reduces the amount of dopamine that the brain receives. The delusions and hallucinations are reduced or stopped in an easy and short time space. A major strength of this approach is that it can be tried and used if other methods have not worked such as ECT. There is large evidence that this method of treating schizophrenia works in 90% of cases. This therapy reduces the level of hallucinations the patient experiences. This therapy is used worldwide, in many cultures and therefore it does not suffer from a cultural bias but can be applied to everyone. However, these drugs have shown that tardive dyskinesia is a common result of this kind of therapy, 78% of patients are permanently damaged and cannot be reversed.

40. Further criticism is that the drugs, if they block other receptors, other problems could happen. If this happens weight gain will be a result and symptoms similar to Parkinson’s disease. Drugs are the most up-to-date and reliable method of treating schizophrenia and do not suffer from a historical bias. This therapy does not take into account any biological or individual differences between schizophrenia patients and therefore should not be administered to everyone. One psychological therapy for treating schizophrenia is carried out by Tarrier (1971). He conducted what is known in the psychological profession as CBT, cognitive behavioural therapy. During this therapy the patient is asked to think of thoughts and ideas they have in their head and locate the cause. The therapist helps the patient change the way the patient interprets these thoughts into a much more productive way. An example of this and applying it to schizophrenic patients would be looking at a thought they get e.g. ‘Everybody hates me’. The therapist would help the patient to see that this really means ‘Even people who like me sometimes get made at me’. This therapy has been ongoing since 1971 and has developed in ways on conducting this therapy and making it more reliable. Although it originated back in the 70s there is not historical bias here because the process has been used in to the 21st century.

41. A major strength of this type of therapy is that there are no negative effects in the outcome, unlike other therapies such as ECT and drugs. CBT has no memory impairment or long term damage. However weaknesses of this therapy are, it does not account for hallucinations. It cannot explain why people hallucinate or have delusions and cannot focus on reducing these symptoms. This therapy has face validity, it makes sense, the patient has negative thoughts, the thoughts are changed, the patient no longer has negative thoughts. 499 words

This therapy is used worldwide, in many cultures and therefore it does not suffer from a cultural bias but can be applied to everyone. • A major strength of this approach is that it is a useful alternative to psychotherapy. • Many people prefer drugs because they don’t require the same effort on the patient’s part. • You just have to remember to take the drug each day instead of attending weekly sessions where you have to think about your behaviour and take control. • This means that many people opt for drugs even though they have to tolerate unpleasant side effects.

There is large evidence that this method of treating schizophrenia works in 90% of cases. This therapy reduces the level of hallucinations the patient experiences. This therapy is used worldwide, in many cultures and therefore it does not suffer from a cultural bias but can be applied to everyone. • There is large evidence that antipsychotics work. • In one study using placebos 55% relapsed if they were using placebos compared to 19% using conventional antipsychotics (Davis et al.). • A particular strength of conventional antipsychotics is that they reduce the level of hallucinations the patient experiences. • Such effectiveness increases the appeal of antipsychotic drugs.
