four of the most useful processves of change
A
consciousness raising, environmental reevaluation, helping relationships, self-reevaluation
3
Q
Health Belief Model
A
the principle that health behavior change is a function of the individual’s perceptions regarding his or her vulnerability to illness and perceived effectiveness of treatment
4
Q
Self-Determination and Motivational INterviewing
A
people are motivated to act by very different types of factors, either because thye value a particular activity (internal motivation) or because there is strong external coercion (external motivation)
5

control by others, control by self, and automatization
6
Q
four general principles of MI to explore resolve ambivalence

Q
social cognitive theory/ecological models
A
emphasizes the interactions between the person and his or her environment
behavior is a function of aspects of both the environment and the person, all of which is in constant reciprocal interaction

two central concepts of social learning theory
A
self-efficacy - patient’s belief to in his or her ability to change or maintain a specific behavior under a variety of circumstances
outcome expectations - the degree to which a patient believes that a given course of action will lead to a particular outcome
10
Q
theory of planned behavior

What is social medicine?
seeks to understand individual clinical problems in a social context and to improve health at multiple levels:
clinical care
community outreach
research and advocacy
28
social determinants of health
The social determinants of health are the conditions in which people are born, grow, live, work and age, including the health system. These circumstances are shaped by the distribution of money, power and resources at global, national and local levels, which are themselves influenced by policy choices.
29
public health
Health-activities that society undertakes to ensure the conditions in which people can be healthy. These include organized community efforts to prevent, identify and counter threats to the health of the public.
30
population health
the physical, mental, and social well-being of defined groups of individuals and the differences or disparities in health between and among population groups
31
global health
the area of study, research and practice that places a priority on improving health and achieving equity in health for all people worldwide
32
epidemiology
study of risk factors and causes of health problems
33
upstream determinants
those that occur at the macro level and include global forces and government policies
34
midstream determinants
intermediate factors such as health behaviors
35
downstream determinants
occur at micro level and include one’s genetics
36
prevalence
proportion of a given disease or condition in a population at a snap shot in time (cross-section)
37
incidence
number of new diagnoses of a disease or condition that develop over time in a population (rate)
38
cumulative incidence
**accumulated number of events in a population in a fixed time: good for short and consistent follow-up time**
25 events out of 108 students with normal baseline BP: 25/108 = 23% phase I CUMULATIVE incidence
39
incidence rate
**number of events per person-years of follow-up time: good for long and variable follow-up time**
25 events per (108 students x 20 months of phase I = 2,160 person-months or 180 person-years), which is 14 per 100 person-years incidence RATE
40
PDSA cycle
PLAN - the change to be tested or implemented
DO - carry out the test or change
STUDY - data before and after the change and relfect on what was learned
ACT - plan the next change cycle or full implementation
41
Heisenberg Principle
The very act of observing a phenomenon alters that phenomenon in some way
42
Hawthorne Effect
The tendency of some people to work harder and perform better when they are observed
Individuals may change their behavior due to the attention they are receiving
43
Developing Goals - SMART
* **S** Specific: choose one specific behavior modifier per goal to work on
* **M** Measurable: Can you measure this against a baseline?
* **A** Attainable or Action Based behavior: Is the goal attainable? Use action words when writing goals such as “I will” or “I do”, rather than “try, should, would, could.”
* **R** Realistic: Do you have honest and realistic expectations of yourself with your time, body, likes/dislikes?
* **T** Timely: is the time allotted reasonable and manageable for you right now?
44
Health Equity
depends vitally on the empowerment of individuals to challenge and change unfair and steeply graded distribution of social resources to which everyone has equal claims and rights
inequity in power interacts across four main dimensions - political, eocnomic, social, and cultural - atogether constituting a continuum along which groups are to a varying degree excluded or included
