effects relate to all levels of functioning: mind, body, spirit

Improve quality of life Increase optimal health and functioning Lower co-morbidities Increase awareness Essential for preventing chronic conditions.
Explain the Transtheoretical Model of Health Promotion?
Addresses disease prevention and health promotion interventions that require a change in health-related behaviours
Pre-contemplation: unaware of the problem, denial of change, no intent to change for next 6 months.
Contemplation: intent to change in foreseeable future. Likely to ask questions.
Preparation: ambivalence regarding unhealthy behaviour, strong desire to change to healthier habits. Change within the next month.
Action: Changes made, less than 6 months. May not see changes yet, likely to revert to unhealthy behaviours.
Maintenance: Continued over 6 months, started experiencing positive effects.
