Lecture 1 Flashcards
Statistical rarity
Uncommon, unusual
Are MHP rare?
Deviance from norm
Quite a judgement call
Distress
E.g. a person with anxiety may be very unhappy.
But some people with MHP do not experience distress.
Dysfunction
E.g. having depression may make it hard to hold down a job.
But functionality is defined by social norms.
MHP
A significant source of distress to individuals and families.
A considerable burden on health resources of societies.
WHO says 1 in 4 people will experience a MHP during course of their lives.
Diagnosing MHP
Diagnostic and Statistical Manual of Mental Disorders DSM-5 (American Psychiatric Association 2013)
What is a ‘mental disorder’?
According to DSM-5:
- A syndrome
- Characterised by clinically significant disturbance in an individual’s cognition, emotion regulation or behaviour
- Reflects a dysfunction in the psychological, biological or developmental processes underlying mental functioning
- Associated with significant distress or disability
- Excludes culturally approved responses and socially deviant behaviour
Advantages of mental health diagnosis
- Assists communication about research + treatment
- Brings relief through appearance of an explanation and awarenes that others have the same problem
- Assists managers/policy makers decide which problems are serious enough to deserve treatment or funding
Disadvantages of mental health diagnosis
- Locates problem within individual
- Suggests an illness, ignores social causes
- Decreases hope of recovery
- Stigma from labeling
- Categories vs. dimensions (not normal/abnormal but extensions of normal behaviour/problems)
- Poor reliability - experts can’t agree about who has got what
- Poor validity - diagnoses don’t look the same or predict behaviour, future or response to treatment
- Co-morbidity
Models which explain MHP
- Historically - people have always tried to explain abnormal/deviant behaviour
- All explanations represent a particular ‘worldview’
- Explanations for deviant behaviour results in different treatment approaches
Historical explanations
- Early middle ages: Demon possession - exorcism
- Late middle age: witchcraft - ducking
- The ‘Enlightenment’ 17th-18thC : Categorisation and confinement - the search for ‘illness’ e.g. blood letting
- 18-19thC - Pinel & Tuke ‘moral treatment’ e.g. eradicating promiscuity (women)
= more humane
Current explanations and approaches to MHP (medical model)
- Uses metaphors of physical illness to describe MHPs
- Genetic and neurological explanations
- Tends to ignore psychological and social explanations, yet strong evidence for this
- Tends to propose medication as a primary solution
Criticisms of medical model in MH
- Over-simplistic representation of genetic causality
- ‘No patient has ever benefitted from genetic research into mental illness’
- Weak evidence for relationship between ‘chemical imbalance’ and MHPs
- Even where neurological differences have been found - brain differences can be caused by env so it is not clear that neurological characteristics is ‘cause’ of problem
Advantages of medical model
- If it works, it works fast (medication)
- Avoids dealing with causes
- Cheaper?
Disadvantages of medical model
- Suggests problems are an illness
- Ignores psych-social causes
- Doesn’t help people to help themselves
- Adverse effects
