Week 1Lecture 1
In 1900 people got killed by infectious and parasitic diseases. It happened
to them. In the 21st century they believe we contribute to it ( eg. Cigs) and
increase risk.
- Positive health behavior; is good for you (veggies)
- Negative health behavior; we should do less of, not so good for
you( smoking).
Locus of control; peoples believes about what causes the outcome of
someones life.
- Internal locus of control; you have personal control over outcomes
- External locus of control; outside forces determine outcome. Broad
range of external factors. God.
Internal locus of control stands on his own. By the external locus of
control the environment, powerful others and chance decides what
happens.
CBT; the change that they made is in the therapist control. What
happens if they need to be on their own. We need to make sure that
they know that the changes they made are due to their own and not
due to the therapist.
,Self- efficacy theory; our perceived ability how successful will you be at
performing the desired behavior given your abilities and the unique
situation (running while it snows). Self- efficacy is measured in the
confident in the fact of various obstacles (can I run while I’m tired or
during bad weather). You have control over your own actions in a certain
extend.
Self efficacy; past performance (have you done it before and was
it successful?). – vicarious experience (observing others in particular
actions), - social persuasion (the feedback from other people, voices
from network around you), - physiological/affective states (emotional
reaction eg. Sensitivity, palm sweating if speaking in lecture).
Theory of reasoned action; underlying your behavior is a intention of
behavior, this intention can be actual behaviour or you have eg. The
intention to work out but you don’t engage in the actual behavior. Your
intention depends on your attitude towards behavior and subjective
norms.
,Theory of planned behavior; theory of reasoned action + perceived
behavioral control (measures of self- efficacy). Perceived behavioral control
leads to behavioral intertion and actual behavior and a mediator.
Perceived behavioral control; do you
think you have the willpower? Measure self- efficacy
, Health belief model; why are people following their doctors for example.
Perceived threat consist of the perceived susceptibility and perceived
seriousness. Low perceived susceptibility (I can still drive while drunk,
susceptibility to get into an accident). Perceived seriousness (what do you
think are the consequences?). outcome expectations consist of perceived
benefit ( working- out has benefits for my health) and perceived barriers
( buying gym membership). The perceived threat and outcome
expectations lead tot the likelihood of an action. You also have perceived
control ( how confident are we to change behaviour) and cues to action
( signals you should change behavior, pig sound when you open the fridge)
and health motivation ( the extend to which people want to change).
