A

If it deviates from expected statistical norm - an experience most people do not have

Q

What is the third approach to defining psychopathology?

A

Results from “harmful” dysfunction. A physical or mental mechanism cannot perform its natural/normal function, which causes harm to the person considering the culture which they live. implies: not every such dysfunction leads to disorders

Q

What is the effect of culture on mental disorders?

A

All mental disorders are shaped, to some extent, by cultural factors. But no mental disorders should be entirely due to cultural or social factors. Disorders should occur across cultures. Social and cultural influence is recognised in the DSM-5

Q

How is the mental illness identified using the DSM05?

A

A formula (or prescription) for the identification of mental illness provides for a “common language” for understanding; facilitating efforts such as an understanding of the epidemiology of psychopathology.

Q

What are the imperfections of the DSM?

A
  • Process criticisms (field trials, composition of task force).
  • The lowering of diagnostic thresholds
  • The introduction of new disorders without a clear scientific basis
  • Failure to test/demonstrate validity of diagnostic categories
  • Reification of ‘disorders’
  • Failure to deliver on the promise of neuroscience
  • The reduced ‘reliability’ of many diagnoses

Q

what are the implications of the imperfections of the DSM?

A

Awaits empirical evidence and is yet to play out but some anticipate that:

  • medicalisation and stigmatisation of normative experiences
  • diagnostic inflation and false epidemics

25
What is epidemiology?
The scientific study of the frequency and distribution of disorders within a population
26
what does epidemiological data tell us?
Tells us which disorders are most common [These data are hard to ascertain (why?): when estimates vary, they need to be reconciled]
27
What does national and international data suggest about mental illnesses?
it is a staggering health problem
28
Incidence
the number of new cases of a disorder that appear in a population during a specific time (e.g. per year)
29
Prevalence
the number of active cases of a disorder in a population during a specific period
30
lifetime prevalence
total proportion of people from a population who will have a disorder at some point during their lifetime
31
What are some key studies or surveys that provide benchmark data for mental illness?
– National Comorbidity Survey Replication (NCS-R) – The World Health Organisation Global Burden of Disease – Australian Institute of Health and Welfare Surveys (Australian-specific data)
32
According to the WHO Global Burden of Disease Study (1990; 2004), how many deaths do mental illnesses cause?
1% of deaths
33
According to the WHO Global Burden of Disease Study (1990; 2004), how does mental illness affect disability?
Accounts for 47% of disability in developed countries and & 28% of disability in un- (or under-) developed countries respectively.
34
What is the predicted effect of mental health by 2020?
By 2020, mental health problems & mental disorders will account for as much as 15% of the worldwide “disease burden” (mortality plus disability).
35
how many australians meet the criteria for mental disorders in the last 12 months?
1/5 3 million experience symptoms of a mental disorder each year 45% of all australians between 16-85 will experience a mental health related disorder during their lifetime
36
Most common conditions?
Depression, anxiety and substance use
37
Descriptive psychopathology
diagnosis does not imply an understanding of causes of aetiology. A descriptive apporach makes a classification on whether particualr signs and symptoms are present. Most have no defined cause
38
what infers an effective treatment?
Explanations of abnormal behaviour and mental illness may vary over time and across cultures; leading to different treatments.
39
What is fever therapy?
To induce ‘fever’, blood from people with malaria was injected into psychiatric patients
40
what is the rationale of fever therapy?
Observation that symptoms sometimes disappeared in patients who became ill with typhoid fever
41
Insulin coma therapy
Insulin injections (producing hypoglycaemia and coma)
42
Rationale of Insulin coma therapy
Observed mental changes among some diabetic drug addicts when treated with insulin
43
Lobotomy
Surgical procedure involving cutting nerve fibres to disconnect frontal lobes from the rest of the brain
44
Rationale of lobotomy
Observed that same surgery in chimpanzees lead to reduced expression of negative emotion during stress
45
Biological assumptions about human nature
competitive but some altruism
46
Psychodynamic assumptions about human nature
aggressive, sexua
47
Cognitive-behavioural assumptions about human nature
neutral abula rasa - refers to the epistemological idea that individuals are born without built-in mental content and that therefore all knowledge comes from experience or perception
48
Humanitic assumptions about human nature
basic goodness
49
biological causes of abnormality
neurochemicals and genes
50
Psychodynamic causes of abnormality
early childhood experiences
51
Cognitive-behavioural causes of abnormality
social learning
52
Humanistic causes of abnormality
frustration of society
53
Biological treatment types
medication and other physical things
54
Psychodynamic treatment types
psychological therapy
55
Cognitive-behavioural treatment types
CBT
56
Humanistic treatment types
non-directive therapy
57
Biological paradigmatic focus
bodily functions and structures
58
Psychodynamic paradigmatic focus
unconscious mind
59
cognitive-behavioural paradigmatic focus
observable behaviour
60
Humanitic paradigmatic focus
free will
61
What does an integrative model suggest causes mental illness and the importance of psychosocial factors
interactions between many factors - biological, social, economic, psychological, spiritual and environmental. These factors exert influence on many different levels - individual, family, community, state, national and global. Some of these factors can be called psychosocial factors which are important determinants of mental health
62
systems / biopsycholigical / integrative approach
integrates evidence across different fiels of psychology. such evidence may include: genetic, biological, behavioural, emotional, cognitive and social factors.
63
Diathesis-stress model
mental disorders develop when a stress is added on top of a predisposition (diathesis)
64
Equifinality
different experiences can lead to the same experience
65
multifinality
same experience may lead to different outcomes
66
genetic influences of Karen
inherited overactive sinoaortic baroreflex arc (tendency to overreact to sudden increases in blood pressure, but reducing blood pressure. The possible genetic predisposition to this behaviour as suggested by the diathesis-stress model
67
biological influences of Karen
light-headedness and queasiness | fainting
68
behavioural influences of Karen
conditioned response to sight of blood or related stimuli (e.g. words, imagery) Escape and avoidance of situations involving blood - negative reinforcement behaviour may be reinforced by responses of family/friends
69
Emotional-cognitive influences of Karen
increased fear and anxiety - heightened threat response | vigilance to situations
70
Social influence of Karen
fainting results in disruptions at university and home | friends and family rush to her help
71
Mental health professions
``` Psychiatry Psychology social work nursing occupational theroay ``` Each brings a different perspective. when working together, can enrich understanding of health and wellbeing
72
Role of GPs
GP as a gateway service - mental health care plans - specialist referrals - treatment provider 86% of mental health related prescriptions (subsidies and under co-payment) were provided by GPs with 8% being prescribed by psychitrists and 6 % by non-psychitist specialists
73
syndrome
a collection of symptoms that occur together and are assumed to represent a specific type of disorder
74
diagnosis
the identification of a syndrome as a classifiable disorder
75
differntial diagnosis
diagnosis aimed at determining which of two or more disorders is present
76
comorbidity
the presence of two or more disorders in the same individual at the same time; for example, a mood disorder and substance use disorder
77
epidemiology
the scientific study of the frequency and distribution of disorders within a population
