What are the leading causes of death?
Human behaviors: tobacco and alcohol consumption, dietary behaviors, physical activity and sexual practices.
What influences better health outcomes?
Behavior changes
Why is it important to understand behaviors?
Understanding behaviors can inform policies, and reduce avoidable mobility and mortality.
According to Davis et al what is important in maximizing the potential efficacy of interventions?
Understanding health behaviors and behavior change.
What might increase the effectiveness of interventions according to Davis et al?
More appropriate theory.
According to an article by Davis et al, “Most theories applied to public health interventions tend to emphasise individual capabilities and motivation.” True or False?
True; because these are important factors in achieving or successfully changing a behavior.
According to an article by Barley & Lawson, what factors influence behavior changes?
health beliefs, past behaviour, intention, social influences, perceived control and the context of the behaviour.
How can we increase one’s intention or ability to perform new behaviors? Or, what are the three significant factors to consider the likelihood of that person performing a behaviour (intention)?
• Attitude • Social norms • Behavior control
What are the techniques for changing behavior?
Community organizations/development Social marketing Education (as a transformational activity) Transformational education
How can we increase the likelihood of behavior adoption, according to the Health Belief Model (HBM)?
By modifying their belief of personal or perceived threat of illness; belief of effectiveness or perceived benefits of recommended health behavior/action and; self efficacy
What is the “psychological and behavioral theory” that HBM is derived from?
• One’s desire to avoid illness or get well. • One’s belief that a specific health action will cure or prevent illness.
What are the six (6) constructs of the Health Belief Model theory?
Perceived susceptibility “ severity “ benefits “ barriers self efficacy Cue to action (internal or symptoms & external i.e. advice from others)
What does self efficacy refer to?
One’s belief or confidence in their ability to successfully perform the behavior.
True or False, persons are more likely to perform behaviors that are more desired.
True!
How can we change behaviours?
Focus on the specific behaviour and specific audience
In the Theory of Behaviour Change, what does this example, the person belief about contaminated drinking water, or their belief about the likelihood of spilled pesticides leaching into groundwater, refer to?
Attitudes, a person’s belief about a specific behaviour.
In the Theory of Behaviour Change, in the following example, a person thoughts about what their neighbor believes about contaminated drinking water, and if they believe that their neighbor would approve or disapprove or even notice if their careless behavior resulted in pesticides leaching into groundwater near a well; what factor is this referring to?
Social norms
In the Theory of Behaviour Change, read the following example: the person thinks it’s possible to avoid contaminating groundwater with pesticides, and they think that they have the skills or resources to keep the pesticides from contaminating the groundwater near a well; what factor is this referring to?
Control beliefs OR perceived ability to control OR behavioural control.
What are the Behaviour Change theories?
• Integrative model • Theory of planned behaviour • Theory of reasoned action • Cognitive dissonance • Value-Belief-Norm theory • Diffusion of Innovation • Stages of change theory • Social cognitive theory
Why is the theory of planned behaviour important?
It allows us to understand that our beliefs about: the behaviour (attitudes), what others think or believe about the behaviour (social norms) and whether or not we should or have the skills to perform the behaviour (control beliefs) ultimately affects our intention to perform the behaviour and execute/action.
What else should we consider - aside from behavioural intent and skills to perform the behaviour - to determine the likelihood of change?
Whether the person has environmental obstacles or constraints that might support or discourage them from performing the behaviour
How does the Social Cognitive Theory describe beliefs about power and control?
The Social Cognitive Theory states that people are not machines that automatically execute functions from an input; they are able to symbolize, self-regulate and self-reflect.
What questions should we ask to determine the likelihood of change?
Does the person have an intent to change behaviours? - attitude, social norms, self efficacy (individual’s confidence in carrying out the behaviour) and control beliefs (easy or difficulty of behaviour) Do they have the skills and abilities necessary to perform the behaviour Are there any environmental factors that may prevent them from successfully carrying out the behaviour?
