Abnormal Flashcards
Models of Abnormality - Supernatural Influences
- cause of psychological abnormality was that you were possessed by evil demon / spirits
Treatments:
- flogging - makes spirit / demon uncomfortable
- psychosurgery - drilling holes into the brain (frontal lobe) which gave the spirit / demon an exit route
- most people didn’t survive or it had an impact on cognitive functioning
- prayer / exorcism
What is “abnormal” behaviour?
*difficult concept to define
- people who have thought / perceptions that may be unrealistic or different to other people
- inappropriate emotions
- harmful / unpredictable behaviour
- psychological stress can result in physiological symptoms
- behaviour that is personally distressing, personally dysfunctional and/or so culturally deviant that other people judge it to be inappropriate or maladaptive
Models of Abnormality - Biological Factors
medical or neurobiological model
- cause = a result of some kind of physical illness or an imbalance in bodily processes
- view that psychological disorde are just like physical illnesses - they can be categorised and treated
- Hippocrates - theory of humours
- treatments - medical treatments
- 18th century - asylums
- 20th century - psychosurgery, electro convulsive therapy, drugs
Successes of the Medical Model
Dementia - loss of intellectual functioning
Caused by - age, lots of strokes, lots of alcohol, certain viruses or bacteria
Identified certain biological features that can help you diagnose certain disorders therefore you can treat them :)
Problems with the Medical Model
- no good biological markers for diagnosis
- diagnoses are largely based on P’s own account of behaviour and the practitioner’s observations of the P’s behaviour - subjective?
- few new treatments have been developed in recent history compared to the previously large increase in research into the area
- some medications don’t actually cure the problem, they just mask the underlying problem eg depression?
- doesn’t explain all abnormalities:
- there are certain environmental factors / reasons that can explain psychological disorders eg loss of a parent in childhood p, traumatic experiences
Models of Abnormality - Psychological Model
Cause = manifestations of psychological problems are a result of psychological processes eg inner conflicts, childhood experiences etc
3 different theories within:
1) Psychodynamic Theory
2) Humanistic / Phenomenological Theories
3) Cogntive-Behavioural Theory
Psychological Model - Psychodynamic Theory
Freud - late 1800s
- cause = unconscious conflicts and desires
- these desires aren’t admitted in public as they are unacceptable - produces anxiety to talk about them
- kept down by defences in the unconscious which causes conflict
- instinctual impulses cannot stay hidden forever - will eventually break through defences into the consciousness
Treatment:
- psychotherapy - looking for slips to gain an insight into the unconscious to make the person aware of these unconscious desires
Psychological Model - Humanistic / Phenomological Model
Developed by Carl Rogers
- cause = self-actualisation has been blocked
- this can be by parents, society, the environment etc
Treatment = therapy - work with a councillor
Psychological Model - Cognitive-Behaviour Therapy (CBT)
Combination of 2 models:
1) Behavioural / Learning Model
- eg Watson or Skinner
- cause = abnormal behaviour has been learned
- eg phobia - little Albert
2) Cognitive Model
- eg Beck
- cause = negative, maladaptive perceptions of the world & self
- focus on internal dialogue - how they understand the world & self
Treatment - Cognitive Behavioural Therapy
- behaviour aspect - trained to be relaxed
- cognitive aspect - challenge the irrational cognitions
Models of Abnormality - Sociocultural Context
- the effect of the environment in which someone develops a disorder and the effect of the sociocultural context on the disorder
2 factors affect:
1) the way the disorder is expressed
- culture specific disorders
- gender differences
- social expectations
2) the way abnormality is viewed
- biases in diagnosis
Models of Abnormality - Diasthesis-Stress Model
Integrated model - aspects of previous models into one another
Vulnerability factors can predispose people to stressors which lead to psychological disorders
Name the three criteria for defining abnormality
1) Statistical infrequency
2) Norm violation
3) Personal suffering
Defining Abnormality - Statistical Infrequency
Normal = average
Abnormal = deviations from the average
Problem - average is not always desirable or healthy and deviations from the average can actually be beneficial or desirable (high IQ)
Defining Abnormality - Social Norms / Norm Violation
- behaviour is seen to be abnormal if behaviour is seen to violate cultural norms
- eg wearing a bikini in public etc
- problem - social norms vary across cultures and historical cues
Cultures - eg Draguns (1986) Amish communities describe different manifestations of affective disorders compared to typical American cultural manifestations
Historical era - views on women & homosexuality
Defining Abnormality - Personal Suffering
- a feature of many abnormal conditions
- problem - not a reliable measure as it’s subjective and not a feature of all conditions
Defining Abnormality - Behavioural Abnormality
3 criteria
Distress:
- excessive anxiety, depression, dissatisfaction or extremely sadness about oneself or life circumstances may be viewed a disturbed behaviour if the individual has little control over these reactions
- but it’s not a feature of all mental health problems however
Dysfunction:
- behaviours can be seen as maladaptive and self-defeating if they interfere with a person’s ability to work or to form / experience satisfying relationships with others
- some behaviours are labelled as abnormal because they interfere with the well-being of society BUT this is a difficult issue eg terrorists or freedom fighters?
Deviance:
- concerned with the deviance of a given behaviour
- conduct within every society is regulated by norms - behavioural rules that specify how people are expected to think, feel & behave
- some are explicitly codified as laws and violations of these norms defines criminal behaviours
- others however aren’t explicit but are expected eg making eye contact on public transport / an elevator
- people are likely to be viewed as psychologically disturbed if they violate these norms especially if the violations make others uncomfortable and cannot be attributed to environmental causes
Describe research into the prevalence of mental abnormality
Srole et al - 1500 participants:
- 25% marked degree of psychological problem
- 55% mildly impaired psychologically
- 20% psychologically healthy / unimpaired
- so it is actually normal to have had a mental health issue*
National Institute of Mental Health (USA) 1984
- 20,000 participants, 3 cities
- 29-38% experienced at least one psychiatric disorder
Üstün & Satorius (1995) - 14 countries
- 24% had a diagnosable disorder, 9% experienced severe symptoms of a disorder, 31% were symptomatic & 36% were well
What are the 2 classification systems for diagnosing mental health?
ICD-10 and DSM-IV-TR
Describe the ICD-10
World Health Organisation International Classification of Diseases
- covers mental health problems & other disorders
- more of a complete diagnostic classification system
Describe the DSM-IV-TR
Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision
- only covers mental health problems
- very widely used around the world
Describe the DSM axes
Axis 1 - Clinical Syndromes / Primary diagnosis
Axis 2 - Personality Disorders & Mental Retardation
Axis 3 - General / Relevant Medical Conditions
Axis 4 - Psychosocial & Environmental Problems
Axis 5 - Global Assessment of Functioning Scale
Problems of classification
Reliability:
- clinicians using the system should show high levels of agreement in their diagnostic decisions
- this means that the classification systems should be couched in terms of observable behaviours that can be reliably detected in order to minimise subjective judgements
- inter-rater reliability?
Validity:
- the diagnostic categories should accurately capture the essential features of the various disorders
- the categories should allow us to differentiate one psychological disorder from another
- overlap between conditions? co-morbidity?
Criticisms of Classification - Not a mental illness
Szasz
Szasz - there is no such thing as mental illness
- diseases of the brain rather than diseases of the mind - mental illnesses are no different from other diseases
- the term is widely used to describe something very different than a disease of the brain; it’s a name for problems in living
- mental illness is regarded as the cause of human disharmony as living is now taken for granted as being an arduous process
Eg schizophrenia in different cultures - hearing voices????
Criticisms of Classification - Labelling
Effects of labelling - Rosenhan (1973)
- reduces responsibility
- self-fulfilling prophecy
- stigmas that come along with it - clinicians hold predisposed views, society views people differently and the patient themselves
