Health Psychology Flashcards
30/9/19 (41 cards)
People think about health in six different ways…
- Being free of illness symptoms (e.g., I have no lumps, or breaks, I’m not bleeding, coughing or wheezing, have no spots, rashes or blemishes, and therefore I’m healthy)
- Having physical reserves (e.g., if I get ill, and I might, I am strong enough to get well again)
- Leading a healthy lifestyle (e.g., equates health will health behaviours, like eating healthily, not drinking or smoking, and regularly exercising)
- Being physically fit (e.g., having a normal BMI, weight)
- Psychological well-being (e.g., more than being free from diagnosed mental health problems)
- Being able to function (e.g., being able to work, socialise, and to fulfil your obligations)
Health domain: BIOLOGICAL
- Derived from biomedical model
- Equates health with having a sound and disease free body, and attributes illness to dysregulation of bodily systems (e.g., infected cells, hormonal imbalances, broken bones)
- We restore health by treating the ailing body
- Views us like biological machines
Health domain: PSYCHOLOGICAL
- Equates health with a general sense of emotional well-being
- Health thought of as being able to think clearly, problem solve, and to think positively, and maintain self-esteem
Health domain: SOCIAL
- Equates health with maintaining strong social networks and friendship groups, and having foo interpersonal skills
- Health thought of in terms of being able to lead a social life, and contribute to society
Integrated, Bio-Psycho-Social Model (BPSM)
- Systems approach
- Biological (virus, bacteria, lesions, hormones), Psychological (cognitions, emotions, stress, behaviours) & Social (friends, social class, social norms) systems interact to affect health
WHO (1948)
Rather utopian, assuming people can be in a state of ‘complete’ social, psychological and physical well-being, but good it acknowledges multiple systems
Wellness Continuum
Not strictly ‘healthy’ vs. ‘unhealthy’, but existing on a spectrum, in which health and illness can improve and worsen
ILLNESS THROUGH THE AGES: Prehistoric period
Illness caused by evil spirits and treated by trephination
ILLNESS THROUGH THE AGES: Ancient Egypt
Demons and punishment by the gods caused illness. Sorcery and primitive forms of surgery and hygiene were treatments
ILLNESS THROUGH THE AGES: Ancient Greece
Illness caused by an imbalance of bodily humors; good diet and moderation in living world would cure it
ILLNESS THROUGH THE AGES: Ancient China (1100-200 B.C.)
Unbalanced forces of nature caused illness. Treated with herbal medicine and acupuncture
ILLNESS THROUGH THE AGES: Ancient Rome (200 B.C.)
“Pathogens” such as bad air and body humors caused illness. Treated by bloodletting, enemas and baths
ILLNESS THROUGH THE AGES: Middle Ages (476-1450)
Disease was divine punishment for sins, cured by miraculous intervention, invoking of saints, as well as bloodletting
ILLNESS THROUGH THE AGES: Renaissance
Disease was a physical condition of the body, which was separate from the mind. Surgical techniques first used
ILLNESS THROUGH THE AGES: 1800s
Disease caused by microscopic organisms. Treatment was surgery and immunisation
ILLNESS THROUGH THE AGES: 1920s
Disease influenced by mind and emotions and treated by psychoanalysis
ILLNESS THROUGH THE AGES: 21st C
Biopsychosocial causes of disease. Modern flexible methods of treatment
Prehistoric (Paleolithic/Neolithic) Causes
- Mystical/Supernatural/Magico-Religious causes of illness, as inferred from anthropological evidence
- CAUSES:
∙ Bodily invasion by evil spirits
∙ Supernatural possession
∙ Sorcery - TREATMENTS:
∙ Trephination
∙ Geophagy
∙ Exorcism
Ancient Greece
- Science x Religion - illness still clearly has religious connotations = linked with Gods but also the first group to start emphasising the role of body in health and disease
- Various Gods = in charge of different aspects of health e.g. Aesculapius (Greek God of healing and medicine)…..had 5 daughters, who represented different facets of medicine and health: Hygeia (hygiene), Panacea (universal remedy), Iaso (recuperation), Aceso (healing) and Aglaea (healthy glow)
- His staff with twisted serpent = still symbol of modern medicine today. Snake symbolises shedding of skin = rejuvenation/healing
- Hippocrates:
∙ Rejected ancient focus on mysticism & supernatural causes of disease
∙ First to identify the role of BODILY FUNCTION in disease
∙ HUMORAL THEORY (Hippocrates, and later developed by Galen)
∙ Illness: caused by an imbalance between bodily humours (i.e., fluids) - Blood, Black & Yellow Bile, & Phlegm
∙ First to emphasise the role of the body in illness
✳︎ Phlegm - cold, headaches - phlegmatic (detached) - hot baths, warm food
✳︎ Blood - angina, epilepsy - sanguine
(impulsive) - blood letting
✳︎ Black bile - hepatitis, ulcers - melancholic
(serious) - hot baths
✳︎ Yellow bile - stomach, jaundice - choleric
(irritable) - blood letting, liquid diet
= Greeks understood the way to restore health is to treat the ailing body
= first to implicate dysregulated bodily systems in disease processes and first to acknowledge the interaction between mind and body (1st ‘systems approach’) = suggested that imbalance between humours not only affected health, but the temperament, or personality, of the individual - Hippocratic Corpus (collection of around 70 early medical works) → Hippocratic Oath
Middle Ages (Medieval Period) - went backwards
- Disease explained by quasi-religious, spiritual causes, like a punishment, by God, for misdeeds on earth
- One of the precipitating factors was the Great Plague, or Black Death, now known to be a communicable pandemic caused by bacteria.
- At the time, no explanation for this vast proliferation of illness and death, and must be punishment, by god, for wrongdoings on earth.
- Treatment for illness lays with the church, who, because of their ability to drive out demons/spirits with exorcisms, and other things, like torture, could restore health.
- These barbaric procedures were later replaced with penance through prayer.
- Religious ideologies prevail during this time, and this is because the church, taking the view the soul still inhabited the body at the time of death, forbade the bodily dissection, or what we now know as autopsy.
Renaissance (14-15th Century) - SCIENTIFIC ENQUIRY RE-EMERGES
- Descartes: CARTESIAN DUALISM
- Physicians: Guardians of body - amenable to scientific scrutiny
- Theologians: Guardians of mind - not amenable to scientific scrutiny
- Because of thinkers like Descartes (proposed that soul left body at time of death and that mind and body = separate entities = this is called mind/body dualism (mind = non-material (thoughts and feelings) and body = material (heart etc) = Church allowed scientific scrutiny of body
Post Renaissance (14-15th Century) - SCIENTIFIC ENQUIRY GROWS
- Change chronicled through Renaissance art - e.g Da Vinci: drawings exploring human anatomy such as Virtruvian Man
- Moving away from mystico-religious views … Illness now thought of in biological terms
- Anton Leeuwenhoek: Developed first microscope (microscopy) - For the first time, see disease located in faulty cells
19TH Century: Foundations of Modern Medicine
- Wilhelm Roentgen: X-rays - Physicians now able to see bodily organs - normal vs. dysregulated
- Rudolf Virchow: Cellular theory - Disease caused by damaged cells, not bodily humours
- Edward Jenner: Small pox vaccination - godfather of immunology - innoculated with cowpox, non fatal disease that is a much milder form of smallpox, means being immune to smallpox, a disease that was the major killer of the time
- Louis Pasteur: Germ theory - bacteria & viruses colonise cells, making them malfunction, thus illness - micro-organisms cause malaria, pneumonia, leprosy, diphtheria, typhoid - development of biological treatments (e.g., penicillin)
20TH Century: Biomedical Model
- Separation of mind & body - dominated medicine for 300+ years
- CAUSE:
∙ Disease has a biological origin, e.g., infected cells/hormonal imbalance etc
∙ Views people as biological machines
∙ Health restored by ‘fixing’ the biological machine - LIMITATION:
∙ Reductionist: Illness reduced to dysregulated biological processes - ignores the contribution of psychosocial factors
∙ Ignores psycho-social contributions - Illness can be explained by dysregulation of biological/physical processes, and we must treat the biological machine to restore to health. That is not to say however, we always did so humanely, and until 1967, barbaric procedures, like transorbital lobotomies, were still being used as treatment.
- 19th C: diseases = single cause - diseases characterised by infection (communicable) - FIX THE BODY: Decline in infectious pathologies/death rates decreased owed to advances in biological treatments?
✳︎ Discovery of penicillin
✳︎ Vaccination
✳︎ Improved hygiene
✳︎ Improved nutrition
✳︎ Improved public health - 20th C: non-communicable diseases where risk factors are not only biological, but emotional (i.e., stress) and behavioural (i.e., smoking, alcohol, lack of exercise) - emphasis here more on multiple, interacting bio-psycho-social contributors to disease
