Lecture 2 Flashcards
What factors influence you food choices and eating behaviours?
Environment \$\$ Culture Skills and knowledge Convenience People Attitude and values Preferences Access
What does Health behaviours referee to?
Actions of individuals, groups and organizations as well as those actions determinants, correlates and consequences
-think about behaviours behind. the. action
What does health behaviours do?
Social change Policy development and implementation Improved coping skills -people are healthy in all situations Enhanced quality of life -how people feel about things
Health behaviour is not only observable but what else?
Mental evens and feeling states involved
How do you change health behaviours?
Need to change: Beliefs Expectations Motives Values Perceptions Personality Characteristics Overt behaviours
What are the 2 things we must do to change health behaviours?
- Understand the behaviour
- what things influence the behaviour
- come up with strategies to. change behaviour - Transform knowledge about. behaviour into effective strategies
What is a theory?
Set of interrelated concepts, definitions and propositions that present a systematic view of events or situations by specifying. relations among variables, in order to. explain or predict events or situations
-way to predict behaviour change
What do theories explain?
Behaviours and suggest ways to achieve behaviour change
-good for planning, implementation and evaluation
What is a concept?
Major component of theory of building blocks
What aree constructs?
Concepts adopted for use
-steps that break down thee constructs
What are variables?
Empirical counterparts or operational forms of constructs
Specify how a construct is to be measured
What are the most important constructs to predict and change behaviour?
Intention (one of the highest) Skills Anticipated outcomes (has to believe its good) Social Normative pressure Self image Emotional reaction (need to value something to move towards a behaviour) Self efficacy (confidence) Environmental constraint s
What are shared assumptions about commonalities among theories?
Health behaviours reflect expected value
Inherent in all theories
- behavioural motivation
- barriers to change
What are commonalities among theories?
- Perceived barriers inhibit behaviour change
- Perceived risk
- Self efficacy or confidence
- Decisional balance
- Intention
How do you chose a theory?
depends on the Behaviour being studied
- Health belief model
- Transtheoreeetical model
- Theory of planned behaviour
What are thee steps in the trans theoretical model?
Precontmeplation-unaware or not interested in change
Contemplation-considering behaviour change but know costs
Preparation- Intentions are made. Ready for action oriented strategies
Action- behaviour change in progress
Maintenance- Behaviour change for more than 6months
What is the theory of reasoned action/ theory of planned behaviour?
Individual motivational factors as determinant of the likelihood of performing specific behaviours
What is the underlying assumption in the theory of reasoned action/ theory of planned behaviour?
Intention is the best predict of behaviour and determined by:
- Attitudes toward the behaviour
- Social normative behaviours toward the behaviour
- Perceived control over the performance of the behaviour
These are the constructs of the theory
