Midterm 1 Flashcards
3 historical perpsectives of helath and illness
1) ancient greece: illness is bodily function
2) hippocrates: idependent of mind; four humors (blood, black, yellow, phelgm etc.)
3) Galen: different disease have diff. effects of body
Renaisssance (Descarte)
- descarte thought of new model of mind/body relationship that are spearate but interact through the pineal gland
- illness is part of body
- once conclude that animals have no souls = dissection is safe
2 aspects of monism
1) materialism: only matter is mind (brain)
2) idealism: all is mind and the body is manifestation of mind
What happened when the biomedical model gained interest?
- identify pathogens that cause disease
- development of physical treatments (e.g. vaccines)
- advance in physical techniques at a fast rate (e.g. cancer treatment)
Criticism of biomedical model (4)
1) Reductionist: ignores complexity of factors invovled in helath
2) Mechanistic: assumes that every disease has primary biological cause
3) Dualistic: neglects social and psychological aspect of individaul
4) Disease oriented: emphasis on illness over health
Criticims of the biopschosocial model
- not a real model
- is a reaction against biomedical and attempts to inquire about both psychoanalsis and behaviourism
- not an explicit theory (not that much literature) - is a guiding framework
Clinical Health Psychology
- most mainstream of HP
- overlap with clinical psychology
- focus on the physical illness and dysfunction - focus on individual
Public HP
- focus on promotion and prevention at population level
- takes time and difficult to measure
- need to address underlying factors (because 1 thing leads to another)
- more interdisciplinary of HP
Community HP
- focus on collective level
- seen as outcome of social and political problem
- work with community and action research for empowerment
Critical HP
- evaluate theories and practice and how they maintain unjust social relations
- focus on concept of power and health differences
- turn critical eye back on discipline
Tension - individualism vs. focus on social context
individual = perspective of person’s thought, beliefs
social context = focus on gender relationship, politics
Tension - realism vs. social construction
realism = real causes that need to be fixed
social constructionism = beings in interpretation and symbols attached is important as how people related to illness
Tension - empirical vs. theretical
empirical = get the evidence then we know what to do (more biases) theroretical = sometimes that's not enough e.g. need to address how to gather evdience, think about issues
Core level:
- individual and specific factors that can’t change e.g. sex
Level 2:
- individual and lifestyle e.g. diet, smoking
Level 3:
- social e.g. suport, peers
Level 4:
- society with bad food security, water, and sanitation (biggest factor)
level 5:
- socioeconomic (macro social factors) e.g. dictatorship, hurrican belt
Characteristics of Onion Health Framework
- wholistic
- concerned with health determinist (not just treatment)
- places each layer in context of neighbours
- interdisciplinary flavor
- no claim for 1 being more important
- complex
Describe Yogi studies that contradicted dualism
- pulse waves from artery decreased to almost zero (heart rate decreased)
- muscle control and heart sounds dimished
- reduction in oxygen intake
- less discomfort in cold water task (oblivious to external stimulation during mediation)
What is Sociohistorical context ?
- our sociohistorical context is now different than 100 years ago e.g. consider implications of politics, economics etc.
Cross-cultual psychology
- fixed system of beliefs, meaning, symbols etc. that group shares (always comparing a set of variables)
Cultural psychology
- development and dynamic system of signs that exists in changing narrative/stories
What are western health belief systems (4)
1) classical views
2) christian views
3) biomedicine
4) biopsychosocial
Galen Humors (4)
- Blood, yellow bile, black bile, phlegm
Christian Ideas (Western)
- revovled around galen humors
- based on religion dominant
- 7 deadly sins associated with pathology (key element of health)
- shift from naturalistic thinking to moral thinking (religion)
Biomedicine (western) (2) - what causes illness?
- 1) Positivism (neglects social part of medicine): direct observation gives access to real world
- 2) Individualism (cuase of problem in individual; staying healthy in person’s control)
- shift from bodily process to concept of quality of life
Example of failed assumption in biomedicine
- Helicobacter pylori - belief that bacteria cannot survive in stomach so scientist drank a beaker of H. Pylori to prove hypothesis
Taoism (Chinese)
- balance of yin and yang; misblanace = ill health
- use acupuncture and herbal medicine
Confucianism (Chinese)
- grounded in moral conduct
- belief that destiny and character determines illness
- accept illness instead of help seeking
Buddhism (Chinese)
- believe in cause and effect
- comisc justice and retirubtion (you have done something wrong and cosmically you are reaping consequences) - try to figure out what you did wrong)
Ayurvedic medicine
- used by 70% of population in India and world
- humans consists of male and female counterparts (need to keep in balance)
- medicine removes blockage of energy flow
- treatment = yoga, diet, mediation, herbs
African Health Beliefs
- spiritual influences
- communal orientation
- common attribution of illness to ancestors or supernatural forces (may have offended them and need to fix it)
- role of healer to identify source of malicious infelunces (may also be felt by family e.g. no rain)
What is health?
- a social construct (medicine is good answer but can be refused if underlying beliefs and assumptions to not align with biomedical model)
How we define health is dependent on:
- philsophical stance
- our culture
- technologies available (e.g. definition of being dead or alive depends on brain activity where before it was if someone stopped breathing)
- historical moment
- social values and norms guiding us
How can STIs be transmitted
- vaginal
- anal
- oral sex
Types of STIS
- chlamydia, genital warts, gonnorrhea, syphillis & HIV (second 2 more rare)
Incidence and Prevalence of STI
- increase in recent years
- especially in conservative governments (getting rid of sex-ed)
- increase birth rate in teens
- increase syphilis in teenage girls
- increase of AIDS in teenage boys
Greatest affect aged group for STI
- young people (16-24)
- account for 12% population; but more than 1/2 diagnosis
HIV in Canada
- Has been increasing
- 25% were unaware of their infection
- has been viewed as a chronic illness because you can extend life
Knowledge of HIV
- connection between AIDS and awareness
- not due to lack of knowledge
- 1 in 5 in UK not able to identify with main ways of HIV transmission
- 1 in 10 believed incorrectly that unprotected sex between M/F or M/M is way of contraction
- worst knowledge in Southern Africa
Condom use and Risk and why are people more hesitant to buy condoms
- best way to protect against STIS
- in areas where they promote abstinence = more hesitant to buy condoms
Factors associated with risk of sexual behaviour and 2 mediations factors
- associated with smoking (lower inhibition and risk-taking), drinking, drug use and poor academic performance
- mediated by on or off campus
- mediated by gender
Barriers to use of condoms (Madagascar study)
- gaps in knowledge
- misinformation, negative perception (don’t like condoms)
- concerns about social opposition (but is there actual opposition)
Risk behaviours (4) that increase chances of getting STI
1) college students (drugs and alcohol predict unsafe sex)
2) pseudosceince and denalism e.g. AIDS is not caused by HIV and antivertrol virals don’t work
3) social opposition
4) cultural factros
Individual Level Theories
- invovled developing theories about individuals and implemeting intervnetions without their invovled (top-down)
- psychologist develop theory and implement on large group of people
Health belief Model (HBM) (4)
- cognition model: perception that predicts behaviours; try to manipulate cognition
1) percieved susceptibility e.g. risk of condition
2) percieved severity e.g. assessment of seriousness
3) percieved barriers e.g. facilitate or discourage behaviour
4) percieved benefits e.g. positive consequences of adopting behaviour
Protection Motivation Theory (4)
- coping with health threat: if people are afraid of something they will work to avoid it
- threat and coping appraisal
1) percieved severity of threatened event e.g. HIV
2) perceieved probability of occurance (how vulnerable?)
3) efficacy of recommended behaviour (Do I think condoms are effective?)
4) Perceived self-efficacy (e.g. confidence of using condoms) - limited empircal evidence to support PMT
Theory of Reasoned Action (TRA)
- Based on assumption that indivdiual is likely to do what they intend to do
- bebavioural intentions (deteremined by attitudes toward action/behaviourand are subjective norms)
Criticism of Theory of Reasoned Action
- does not take into account political or economic constraints, some things are not under our voluntary conrol - may operate on subconscious principals
Theory of Planned Behaviours (TPB)
- most cited theory in psychology
- but some behaviours difficult to control in voluntary way
- perceieved control e.g. how much do I believe I have control over quitting smoking
- reflects past obstacle and success
- stil missing religion, culture etc.
Information-Motivation-Behavioural Skills MOdel (IMB)
- skills are emphasized; not enough to want to do something but need the skills to implement it
- pre-requisites for good actions (relevant information about risks; motivation for safe sex; beahvioural skills (e.g. negotiate condom use)
- motivational interview strategy for buildling up drive to change beahviour in life with decision
Common sense model (CSM)
- aka self -regulatory model (SRM)
- Core-construct - illness representation (what is your understanind/perception of illness)
- integrate normative guidelines held by people, to make sense of symptoms and guide coping actions
- no obvious guidance for intervention or evaluation
Transtheroretical Model
- aka stages of model change
- influence in literature on health beahviour change
1) precontemplation
2) contempolation
3) preparation
4) action
5) maintenance
6) termination/replase - mixed results
Social cognitive theory
- examines social origins of behaviour (as well as thought process)
1) observational learning
2) self-efficacy: beliefs about own capabilites to infleunces events affect their lives - application of theory: use of role models in mass media to shape attitudes
Evaluation of Individual Theories (for sexual health)
- Meta-analyses suggest that only a small amount of variance is explained by any of the theories in sexual health
Most effective and least effect theories of change for STI
Most: attiudinal arguments, educational info, behavioural skills argument, behavioural skills training
Least: induce fear of HIV
Critique of Individual-level approach (individualistic bias)
- important process of choice and responsbility all located in indivdiual’s head (huge assumption)
- sexual intercourse is joint activity
Critique of Individual-level approach (problems of validity)
- null hypothesis significance testing: small samples; students
Critique of Individual-level approach (culture, religion, gender)
- they are not part of theories
Critique of Individual-level approach (universalism)
- controversial esp. when studies are done in labs
Critique of Individual-level approach (complexity of motivation)
- riskiness could be part of motivation, not deterrent e.g. sky diving
Role of Food in Society
- social activities full of symbols and meaning (not just surviving)
- changes in society have produced changes in consumption habits e.g. anorexia, obesity
Obesity in Canada (trend in general and in youth)
- Prevalance in canada has been declining
- Prevalence in children and youth increasing
Classes of obesity in Canada (3 classes)
Class 1: high risk 30-34.9
Class 2: very high risk 35-39.9
Class 3: extremely high risk 40+
Healthy: 20-25
Obesity Health Risks
- hypertension or high blood pressure
- coronary heart disease
- type 2 diabetes
- stroke
- gallbladder disease
- osteoarthritis
- sleep apnea and breathing problems
- some cancers e.g. breast, colon, endometrial
- MHC e.g. depression
Obsiety Tredns and Prevalene (world wide)
- significant differences between countries and sub-groups of people
- prevalnce realted to lifestyle e.g. fruit/veg intake; leisure time, physical activity
- sharp increase in most places
Describe disease of affluence (obesity)
- total calorie intake increased as food become more processed and energy dense
- problems of obesity become common in developing countires
- associated with lower SES (budget restriction)
Food politics (2- tensions)
1) social inequality and obesity
2) corporate agenda
Food consumption characteristics (4)
1) increasing # ppl eating outside (prepared foods)
2) typical availability food outlets have high calories
3) people eat more than they need; having lower activity levels
4) role of food industry - decides how the food is prepared and what ingreadiants go into
The food industry and how does it influence our health?
- advertising and other methods of influence
- corporate interests in encourage high food intake
- additives (e.g. flavouring); not healthy; increase competitiveness (e.g. fat, salty, sugar) - concerned about profit
Problems of Sustainability
- contribution of livestock to Greenhouse Gas emissions
- Food transport and CO2 emission
- demand for milk and meat increasing (will eventually be unstainable)
Cause of obesity
- genetic predisposition
- culture (kinds of food e.g. more lean cultures)
- diet
- inactivity
- human microbiome (stomach bacteria)
Evolutionary perspectives (obesity)
- human evolution history geared toward nomadic lifestyle (groups of ppl who follow food sources and climate) - always active
- current lifestyle different in which genomes evolved
2 evolutionary events that influence our increase in food intake
1) agricultural revolution: cultivation of grains lead to large social organization
2) industrail revoltuion: mass trasportation (of people and food); labour savings (less active); mass communication; corporate influence –> control of food shifted to corporation
Ecological Model of Obesity
- obesity not a disorder of individual but consequence of interaction b/w person and environmental context
- daily energy of humans need to be increased while consumption needs to be increased
Environmental Influences on Food Choices
- micro (family) vs. macro (economy) level infleunces
- physical (close to sotre) and economic (budget); socio-economic influences
- quality of food available
- access to fruit/veg through grocery stores (lower access in poor neighbourhoods; those with access have lower rates of obesity)
What is is that change in our environment related to food?
- food production is controlled by corporations
- food distribution planned on large scale e.g. grocery stores
- food environment changes depending on degree of affluence (where you can afford to live)
- constant food promotion
Describe characteristics of an Obesogenic Environment
- presence of supermarket = lower obesity
- presence of convience stores = higher obesity
- obesity - lower income racial minority
Descirbe how Food, Race, Class and the environment influence food inequalities
- 3x less places to drink in rich neighbourhood
- 4x more supermarket located in white neighbourhood
Reasons for environmental inequality
- restating of grocery store buisiness
- cheaper rent for people in commerical locations (more fast food)
- ability of affluent communities to resist unwelcome commercial activitites
Food Promotion Infleunce Children
- children view 15 commercials every day
- 98% promote high sugar, fat, sodium
- high exposure to food advertising = leading cause
- coporations do this to compete with other companies
TV and Children
- food advertised for fun, taste, - not health
- link b/w amount of TV viewing and obesity and cholesterol levels
- high TV = high junk food consumption
- conflict between interest of coprotation and society
Interventions of obesity
- HP use social cognition models but these models dont’ include research addressed today e.g. location & affluence
- Inidivudl level interaction e.g. education, health promotion (but need to fight social and corporate infleunces)
- vegetarian diets
- biological interventions e.g. bariatric surgery, obesity pill, probitics
- correct current public health approaches
- community level approachs
- policy level approaches
Attitudes to alochol
- societal ambivalence across time
- prohibition in US
- then recieved medical attention that people cannot return to moderate drinking levels (but different in Europe)
- strongest abstinence is AA
Attudes to alcohol (global)
- legal almost everywhere except some countires with majortiy Muslim population and religious socieites
- dominant view = alcohol ok in moderation; harmful in excess
Extent of Problem
- 3.7% global morality rate and 4.4% with social rpboems
- Europe has a huge morality rate from drinking
Historicl and cultural infelunces of alcohol
- In india, there were colonial infelunces so british empire expanded and had new markets and promoted in india; Ghandi led resistance of abstinence
- Gorbachev in Russia but then levels rose again after he left
- powerful infleuence of international drink companies that infelunce policies
Low risk alchohol drinking guidelines
- females max daily; 2 max week = 10
- males max daily 3; 15 max weekly
single occasion Risks associated with alcohol
- not associated with lower levels
- driving, household accidents
- domestic and vioence
- STI from unprotected sex
regular drinking risks associated with alcohol
- death from liver cirrhosis
- neurological damage
- CVD and cancer
