Q

What is Primary Prevention?

A

Actions/behaviours designed to prevent health problems from arising - target the whole population

E.g. immunization, safe sex, healthy eating

Q

What is Secondary Prevention?

A

Early recognition and intervention to eliminate or reduce symptoms before a more serious illness develops - targets “at-risk individuals”

E.g. diet intervention for increased blood sugar, smoking cessation

Early detection and intervention correlate with the screening

95
Enabling factors?

97
Is knowledge enough to alter behaviour?
No you may believe that a certain behaviour has a certain consequence- but that may not be enough
98
What are we often influenced by?
approval or disapproval (real or imagined) of significant others support for positive behaviours, negative interference from family, friends, and others? (coaches, teachers, coworkers)

1. shaping 2. visualizing 3. modelling 4. controlling the situation 5. reinforcement 6. changing self-talk
101
Shaping?
developing behaviour in small steps start slowly, keep steps small and realistic be flexible but systematic reward yourself for meeting short and long-term goals example: healthy eating
102
Visualizing?
imagined rehearsal mental practice increases preparedness example: marathon run
103
Modelling?
careful observation of other model behaviour after proven success example: presentation skills
104
Controlling the situation?
situational inducement placement in the right situation or group example: smoking cessation Stress inoculation
105
Reinforcement?
positive incentives highly individual tangible rewards, enjoyable activities, social “manipulative” incentives (if you do this, ill do this)
106
Changing self-talk?
altering internal dialogue identify, challenge and replace negative thoughts “blocking” or thought stopping self instructions and positive affirmations

Some Benefits of Goal Setting?
Helps to assess if the change is realistic Helps to organize your thoughts Helps to formulate a plan
108
What are SMART Goals?
Specific - 5 whys, Clear and precise! What exactly do you want to achieve? Measurable - how will you know when you're done, Quantifiable method of evaluating What will you observe? Evidence! Attainable - Realistic, consider resources, timelines Relevant - how does this fit into your life now, Why do you want to reach this goal? Fit with lifestyle, and overall goals? Time-bound - when will you achieve your goal? What's your deadline? A specific date or timeline
109
Transtheoretical model?
“Stages of Change” □ are you ready for a change? □ where are you in terms of readiness? Decreasing order: Precontemplation (not even thinking about it) Contemplation (thinking about making a change) Preparation (planning) Action (executing) Maintenance (committed to the change, avoid relapse)
110
What is the health belief model?
* explains how beliefs, and perceptions may or may not influence your behaviour * perceived susceptibility to the health problem □ evaluation of risk · perceived seriousness of the health problem □ evaluation of the medical or social consequences · cues to action □ reminders or alerts about potential health problems (any source of reminders of what will happen if I don’t do this) · assessment of “cost-benefit” tradeoff, barriers? □ likelihood of preventative action
111
What are the ABCs of Behaviour change?
Antecedent - Events that come before behaviour * physical events, settings, thoughts, feelings, actions of others Behaviour Consequences - Events that come after behaviour * outcomes - affect whether behaviour will be repeated
