A
problem-focused:
-changing the situation, avoiding in future
emotion focused (2 subtypes):

30
what is clinical effectiveness and what is patient reported effectiveness?
clinical: mortality, morbidity, complication rates
patient-reported: value or utility of care to patient
31
what is health-related QoL?
the functional effect of a medical condition and/or its therapy, as assessed by the patient
32
what are PROMS
patient reported outcome measures:
patient ratings of the effects of a disease, condition and/or treatment
33

know what getting (e.g. get x if chosen)
36

38
What is classical decision theory and who came up with it?
von Neumann and Morgenstern
"very rational, and STERN, approach to making decisions, hence the german names"
A normative theory of how people should make their decsisions
probability based
structure linking the choice made with peoples value towards the outcomes of options and the probability of these outcome occurring
39
4 assumptions required for rational decision making
people are motivated to follow rules or axioms
people have complete knowledge of all options
people's representations of opinions, risk and benefits are accurate
people know what their values are and people's values are stable
40
who came up with bounded rationality and what is it?
people don't have the processing capacity to calculate EUT and so use simpler, less effortful strategies
41
what is the 'satisfying' method of decision making and who came up with it?
simon - "simple simon is easily satisfied"
choose a satisfactory criterion and the first option that matches
-eg must have 5 rooms, choose first house with 5 rooms

quick way- attend to part of the information or decision context
choice based on rule of thumb (heuristic)
rule of thumb enforced by experience
subconscious, quick, little effort/emotion
more likely to regret choice or make wrong choice
45
information processing strategies: system 2
"twice as hard, but twice as good rewards"
attend to details- evaluate pros and cons- make choice based on trade offs
conscious, time consuming and emotionally demanding,
results in more stable values
happier with choice made, less likely to regret decision
46
treatment decisions, risk and bias
people find risk difficult to understand and assimilate
perceptions of risk influence choice, not actual figures
people are hardwired to use context to give meaning to risk:
