How do professionals interpret and respond to mental health symptoms?
- a person has a disease with a biological cause
- a person has a disorder - a dysfunction that is mental in nature, whatever the cause
- the symptoms and behaviours are within the spectrum of normal human responses to stressors
Definitions of mental health
- mental health is the freedom from suffering, abnormal behaviour, and distress
- mental health is the absence of mental illness
What is distress?
- mental - refers to feelings, awareness, cognition, behaviour
- health.- is associated with feeling good, while “illness” is associated with feeling bad (however, bad feelings are a normal part of human experience so does having these make a person ill?)
What is abnormality?
Another way to think of mental health and illness is to consider the constructs of NORMAL and ABNORMAL
We usually assume that abnormal = unhealthy
What is dysfunction?
If a persons mental status makes it difficult for them to meet their daily needs and fulfil typical responsibilities, this could be considered dysfunctional
However, individuals capacity is influenced by a persons resources and environment (this is where the social determinants of health start to enter the equation)
WHO definition of mental health
A state of well-being in which the individual realises his or her own abilities, can cope with the normal stresses of life, can work productively and fruitfully, and is able to make a contribution to his or her community
- important to note that some people have less ability to contribute to society due to sexism and racism
DSM definition of a mental disorder
- psychological, emotional, behavioural disturbance
- impairs normal functioning
- allows for negative reactions to stressors and events
- context-specific and a little non-committal
Models of mental health and illness
- biomedical
- psychological-behavioural
- social
most practitioners use more than one model
each prioritises particular causes and solutions for problems
etiology: the cause, or set of causes, for a particular medical condition or disease
Biomedical model
- assumes that there is a binary division - a person is either mentally ill OR mentally healthy
- sees good mental health as the natural human state
- suggest that mental illnesses have specific causes, such as a dysfunction of the brain or neurotransmitters (chemical imbalance)
- mental disorders as a form of “brain disease”, each is a distinct disease with specific causes, which produces dysfunction and the diagnostic symptoms
- causes may be genetic or acquired (through exposure, infection, injury)
Biomedical Model Interventions
brain based interventions are considered the best way to treat mental illness
- psychopharmaceuticals (medications)
- electroconvulsive therapy (ECT) (ECT applies electrical current to the brain to induce a seizure to provide relief for individuals with refractory mood)
- genetic interventions (potentially in the future)
Psychological-behavioural Model
- considers mental disorders to be patterns of thinking, feeling, and behaving that are harmful to individuals
- does NOT assume a binary between mental health and mental illness (more of a spectrum)
- assumes that symptoms (sadness, fear) exist along a continuum, disorders are defined on severity of these symptoms and an accompanying pattern of additional symptoms
- largely individually-focused still
- causes focus on personal experiences (especially early life), experiences, events, producing patterns of thoughts and feelings (mistreatment can lead to distrust and fear)
Psychological-Behavioural Model Schools Practice
- Freudian psychoanalysis
- psychodynamic approaches
- behaviours
- humanism
All of these support the idea that mental illness arises as a result of our personal experiences and perspectives, with a focus on the mind, thoughts and behaviours
Psychological-Behavioural Model Interventions
Treatment within this model relies on psychotherapy - talking and thinking in a collaborative relationship with a practitioner
Types of psychotherapy:
- cognitive behaviour therapy (CBT) (aims to analyse and restructure thoughts and behaviours to help individuals address these two components of mood/mental wellbeing)
- psychodynamic treatment
- humanistic therapies
- existential approaches to therapy
psychotherapy (a method of treating mental disorders, but the practice generally involves talking to a trained professional about thoughts, feelings and behaviours)
Social Model
- sees mental health as a social product, problems are social in nature
- this means that good or bad mental health are socially constructed and produced - defined by social relations and norms
- this model places less emphasis on individual characteristics and qualities, and considers the individual in the context of their social environment
- disorders are not concrete diseases, but “constructed” and redefined in relation to what is “normal” behaviour
- strong critical component: “ill” is a label that shaped by power and culture and conferred upon people and behaviours that are disapproved
Social Model Continued
- suggests that power and culture lead to the labelling of some people, often those who are marginalised, as mentally ill
- social interventions are suggested as a response to mental illness - things like supported housing and employment, as well as larger changes to reduce marginalisation
- demedicalization is also suggested - declassifying a mental illness and looking at social causes rather than individual causes of mental distress
- in this view the “epidemic of mental illness” is actually a symptom of social problems like racism, sexism, inequalities, isolation, etc
what is demedicalizaiton?
process by which issues that are understood as medical problems are redefined and understood through other perspectives.
Homosexuality was once considered a mental illness/medical problems but now is understood as part of the normal range of human sexual behaviours
Biopsychosocial Model (biological, psychological, and social)
- suggests that biological factors, social conditions, and individual experiences all contribute to a persons mental health
- social in this context refers to social determinants of health (income, housing, education, etc)
- tries to consider all of these factors in responding to mental illness in an individual, problems are not just psychological but rooted in social environment
What are biomarkers?
measurable medical signs that objectively and consistently indicate the presence of a phenomenon such as a disease or infection
Measuring or assessing a persons mental health
- very complex
- cannot be measured objectively only subjective assessment
- no biomarkers exist: blood tests and scans may be used in diagnostic work but mostly to rule out other conditions
- no test to prove someone is in good mental health
Diagnostic Tools
- diagnostic and statistical manual generated by the American Psychological Association (APA)
- WHOS international classification of diseases (ICD) –> these guide physicians as they categorise and diagnose mental illness
Diagnostic and Statistical Manual (DSM)
- descriptions of each diagnosis (or disorder), and includes a checklist of symptoms (thoughts, moods, behaviours) associated with each
- a practitioner observes and speaks with patients to make a diagnosis
International Classification of Diseases (ICD)
- used for diagnosis, but also by researchers, governments, and health insurance companies
- definitive classification schemes are highly relevant to public health - we use them to track illness and treatment in health administrative data
- key role in defining what counts as a mental illness, who is deemed “sick” or unwell, and whether the costs of their treatment is covered
Clinical Scales
Another important diagnostic tool
- measure patients mental states with a series of “standard” questions
- answers can be used to determine severity of the condition
- “score” for every item or question is calculated, the total indicates whether the person qualifies for the diagnosis and how severe their condition may be
Hamilton Rating Scale for Depression
- written in the late 1950s by Max Hamilton, a psychiatrist at Leeds University and originally designed to evaluate the performance of the first group of antidepressant medications
- scale is widely available in two common versions (either 17 or 21 items, scored between 0 and 4 points)
- scale/criteria allow for presence of some depressive symptoms as “normal”
- mild/moderate/severe categorisation or “severity” levels (more symptoms, more serious)
