Mental Health and Wellbeing Flashcards
what is diagnostic classification
Based on recurring and reliable patterns of these human experiences
Attempts to categorise and classify these into discrete entities called ‘diagnoses’.
There is nothing inherently wrong with such an approach.
what are the aims of classification systems
Reliability: to ensure that when we talk about these experiences we are all confident that we are talking about and studying the same phenomena.
Assumption: identification and categorisation will lead to understanding of mechanism and cause, which will lead to treatment
name two popular classification systems
Diagnostic and Statistical Manual of Mental Disorders (DSM5)
International Classification of Diseases – 11th Edition
how was the DSM developed
Taskforces – committees of experts in clinical practice of the field. Determine the kinds of categories of mental health difficulties then describing them based on criteria that defines the conditions themselves. Define through consensus and study
Lists of disorders and criteria required to be diagnosed
what are the requirements for being diagnosed with major depressive disorder
The individual must be experiencing five or more symptoms during the same 2-week period and at least one of the symptoms should be either (1) depressed mood or (2) loss of interest or pleasure.
symptoms of major depressive disorder
Depressed mood most of the day, nearly every day.
Markedly diminished interest or pleasure in all, or almost all, activities most of the day, nearly every day.
Significant weight loss when not dieting or weight gain, or decrease or increase in appetite nearly every day.
A slowing down of thought and a reduction of physical movement (observable by others, not merely subjective feelings of restlessness or being slowed down).
Fatigue or loss of energy nearly every day.
Feelings of worthlessness or excessive or inappropriate guilt nearly every day.
Diminished ability to think or concentrate, or indecisiveness, nearly every day.
Recurrent thoughts of death, recurrent suicidal ideation without a specific plan, or a suicide attempt or a specific plan for committing suicide.
To receive a diagnosis of depression, these symptoms must cause the individual clinically significant distress or impairment in social, occupational, or other important areas of functioning. The symptoms must also not be a result of substance abuse or another medical condition.
what is the difference between normal and severe mood fluctuations
Everyone experiences normal mood fluctuations. Sustained mood change becomes more severe, number of people experiencing reduces. Then by the end it interferes with life, even less people have this, its very different from normal mood fluctuations. The dotted line is arbritrary and made up, there is no one point where people suddenly switch into depression. The time length for symptoms is also arbritrary could’ve been 3 weeks instead of two.
what are the critiques of diagnostic systems
In other branches of medicine careful study of symptoms led to the identification of diseases and causes
Our understanding of biological causes in psychiatric disorders is limited, so we don’t know if the recurring patterns we see are actually discrete ‘things’
Unlike other branches of medicine there is no test to confirm
critiques of dsm 5
lacks validity diagnoses based on consensus about cluster of symptoms - not an objective measure
Search for causes has so far not delivered – biomedical causes have not been found convincingly.
Proliferation of mental disorders – more and more added between each edition
Minor changes to criteria make big differences in the rates of diagnosis (e.g. ADHD, ASD, Childhood Bipolar Disorder) – e.g major depressive disorder used to state if they were grieving a death they couldn’t be diagnosed
Financial links between DSM5 task force members and pharmaceutical companies – they received benefits from the companies (motives and biases called into question)
American Psychiatric Association and DSM book as an income stream – psychologists buy = income, the production of the book was delayed, sufficient testing wasn’t done and moved straight to publication for money
what do intrapersonal influences focus on
psychological processes
personal historical factors
cognitive factors
behavioural factors
idea behind personal history
it suggests early history is very informative the idea here is compelling but there is there evidence
describe the systematic review of the evidence for personal history
44 articles between 2001 2011
145,000 ppt
strong association between early life adversity and all forms of psychological disorder in development persistence and severity
events can include Emotional sexual abuse
Emotional physical neglect all found psychological problems but less so for physical
what are the mechanisms behind early history being a factor in mental illness
Intrusions of unprocessed memories - mind attempts to make sense of it they are unpleasant and makes them avoid activation of memory leads to suppression and incoherent story of self
Formation of negative expectancies and self beliefs - blame themselves, person who abused them may have made it seem like their fault as a form of control
Disruption of developmental pathways
Disruption of social bonds - diff to trust others
how are cognitive factors responsible for mental illness
information processing biases can lead to faulty thinking across all parts of the processing chain
what are the well established biased processes
Selective attention to threat stimuli in anxiety - social threats on mind due to evolution
Biases in explicit memory for negative self related information in depression
Over-general memory in depression - unable to define specific times when they felt something as rumination reduces specificity of coding
Lack of memory bias in anxiety disorders
Interpretation / judgement bias - what if ideas
Intrusive repetitive thinking: worry and rumination
Inhibitory control processes - so overused they backfire the more they try to repress intrusive thoughts it comes back stronger, more intrusive thoughts = further anxiety about not being able to control them
how are cognitive models used
experimental studies of biases have informed cognitive modelling of emotional disorders e.g anxiety
describe the model for anxiety
internal or external trigger - perceived threat - anxiety - physiological and cognitive symptoms - catastrophic misinterpretation - safety behaviours that feed back into catastrophic misinterpretation
how are safety behaviours harmful
They dampen the threat they never learn the symptoms aren’t harmful so the beliefs aboiut meaning of the symptoms are maintained
is mental health illness and biased thinking have a cause or correlation relationship
people with biased processing dont have it anymore once they have recovered.
precursors to mh difficulties, not conclusive as could be related to other factors e.g neuroticism
could also be the stress diathesis model - activated by stressful circumstances, once people recover from depression the cognitive biases don’t occur but if put in an experiment that induces a certain mood the biases are activated again more than someone who has never had it
explain how behavioural processes feed into experiences of mental health problems
Avoidance and escape: habituation / extinction – stimulus is unpleasant try to escape it, run away, prevent extinction where it can evoke less anxiety
‘Safety behaviours’: failure to disconfirm – they reduce anxiety but prevent the person from confirming the unpleasant symptoms aren’t actually harmful.
Recent rethinking of avoidance – limited forms of safety behaviour can help, can help them protect and stay in extinction condition for longer.
what are mental health problems
Human experiences
Emotions, perceptions, judgements, thoughts, physiological sensations, urges, motivations and behaviours
That cause distress and difficulties in daily living
That are considered outside of the ‘normal’ range of functioning….?
positive effects of living with a diagnosis
Can make sense
Reduce self blame
Can access services
Can find support
negative effects of receiving a diagnosis
Stigma
Sense of difference
Defeat
what are the macroinfluences on mental health problems
poverty - income inequality
social exclusion
discrimination
multiply discriminated identities
how does poverty impact mental health
reciprocal relationship and feed into one another
poverty = resources not sufficient to meet minimal needs
what are the two hypotheses for the relationship between poverty and mental health illness
social causation - poverty and stress associated with it leads to mental health problems. Global financial crisis confirmed this with worsening mental health rates, mental illness where not been before due to stress of unemployment
social drift hypothesis - mental health problems leads to difficulties keeping job leads to poverty 2 reports investigate this do find evidence of social drift but evidence for social causation higher
how does social exclusion and poverty stigma affect people with poor mental health
Perceptions of people in poverty are extremely negative
Stereotypes abound and are harmful – seen as lazy self centred lacking in competence, blaming stereotypes
Stigma can be internalised – start to think this about themselves
Childhood poverty is particularly damaging – sets up cascade of consequences
is discrimination associated to mental health problems and backed by a study?
review of 12 studies from 2007 – 2013, Primarily cross sectional, with over 55,000 participants
Discrimination associated with a range of diagnosed disorders (depression, anxiety, PTSD, eating disorders)
Statistical controls for poverty, gender, ethnicity, etc etc
what is intersectionality
also called multiple discrimination - interconnected nature of social categorisations e.g race gender etc. these features create interdependent networks of discrimination
what is resilience vs cumulative risk?
Resilience = weather further discrimination further Cumulative = each one added = greater risk for developing mental health issues
what is the evidence supporting either resilience or cumulative risk
Systematic review, 40 studies
‘Resilience’ versus ‘cumulative risk’
Depression and anxiety most common outcome but others studied too
Strong evidence for cumulative risk and weak evidence for resilience
Methodological flaws outlined, but even in the stronger studies racism and heterosexism particularly associated with outcomes
macro influences are important - how do we demonstrate this with the river analogy
Critical suggesting intra individualization perpetuates a system that ignores these factors.
Nowadays calls to work in policy to influence advocacy for influence of large scale factors, sometimes called upstream or downstream hypothesis. Mh treatment as if standing by the river, people drifting down with difficulties so pull them out but more people come down. Go up the stream and discover why they are falling in. rather than curing people why don’t we understand how to prevent people getting it
what is a psychological formulation
An attempt to use psychological knowledge to understand the origins, mechanisms and maintenance of a person’s problems.
what are the five ps of general formulations
Fives p = diff aspects used to understand the problem.
Predisposing factors can be macro or micro – macro = societal micro = personal
Precipitating factors = triggers what lead to this particular problem
Perpetuating = features of environment lead to perpetuating factors e.g harassment or crime or their perpetual tendency to not leave the house
Protective factors = their ability to cope with the problem e.g good social networks intelligence etc.
which leads to presentation of the problem
can general formulations integrate ideas from different theories and perspectives
yes, they aren’t limited to only clinical psychology but can also use theories from other disciplines
examples of the 5 ps of general formulation
predisposing = early loss of parent, sexual abuse by step father
precipitating = loss of job, workplace bullying
perpetuating = isolation rumination unprocessed trauma intrusions
protective = intelligence, determination, resilience, awareness
outcome = hearing voices
positives and negative of theory specific formulation
Harder to integrate different elements
Can be more precise
Due to research base can be linked more strongly to a certain definition of evidence-based practice
Can be limited by syndrome classification
Can also be transdiagnostic
