It is a simplified description of a complex process It is internally consistent: different parts of the model do not contradict each other It is comprehensive: it explains everything (at least everything that is relevant) It is reliable: it works repeatedly, so you can apply it over and over again and get the same result o What are some characteristics of a theory? It is explanatory: it explains some phenomenon It is predictive: it can predict the outcome of situations It is parsimonius: it is simple and sparing - it does not give complicated reasons for whatever it proves Models of Health and Disease o Individual Orientation What are the two kinds of models in this category? Biomedical model and biopsychosocial model What kind of things does the biomedical model look at? It looks at physiological/biochemical alterations, disease mechanics (how a disease works), etc. What does the biomedical model emphasize? Explain these things. So there is an emphasis on logical positivism and reductionism Logical positivism: It is based on empirical observations -> physical evidence that can be tested (i.e. blood pressure) It is verifiable, so we can confirm or disconfirm a hypothesis i.e. Seeing a chocolate bar with X amount of glucose will increase our insulin levelsso we can test this hypothesis It is systematic It stresses the importance of the scientific method Reductionism: This is when we reducing complex phenomenon to its simplest components (think parsimonious) So we want to simplify concepts, theories, and hypotheses into testable constituent parts We look at broad questions and think about simplified ways to answer them What is a limitation of this model? It doesnt take into account social/environmental causes: because these things affect our health as well! Also, psychological factors are ignored Explain how the biopsychosocial model relates to the biomedical model. This model addresses the limitation we saw in the first model (i.e. Psyche and social environment as disease determinants), thus it is more holistic However we STILL look @ individual lifestyle choiceswe havent applied these social determinants to the WHOLE population yet o Population Orientation What are the two kinds of models in this category? Population health model and public health model What is the essence of the population health model? What are its limitations?...
