Information alone is typically not enough. Sure, people must know how to change and that requires good, understandable, readily available information. They also need ongoing feedback, i.e., information that enables them to know how well they’re doing and what adjustments they can make to promote their progress.
But all the information in the world won’t foster change unless people are motivated to make the changes, which includes having:
- Confidence in themselves and their healthcare providers/caregivers
- Resilience to persist when things get tough, frustration, disappointing
- Positive/adaptive emotions, such as love, joy, satisfaction, peace of mind, etc.
- Ability to manage negative/maladaptive emotions, such as high levels of anxiety/fear, disgust, sadness/depression, shame, guilt, etc.
Well, what has to happen for someone to have (or not to have) such motivating characteristics? I suggest that our beliefs and values about ourselves, others, the world, the future, life-purpose, etc. are the primary triggers of these emotions. These beliefs are affected by our experiences, social surroundings, culture, religions, formal education, economic status, life opportunities, etc. Emotions are also influence by our physical condition and stress, and can be affected by certain medications, what we eat, and environmental factors.
As such, this is a very complex question, whose answer lies in a lifetime of complex mind-body-environment interactions.
It may be that comprehensive biopsychosocial assessments can help us to understand what's affecting a person’s motivation to change and to help us address these influences through some type of focused counseling and personalized social (peer/family) support. Rewards and punishments, may also be useful, as long as the negative underlying psychological/emotional issues are addressed and resolved. And finally, making the change process as simple, safe and affordable as possible would help.
But we have to accept that there's no way to motivate everyone to change, nor does everyone have the physical ability to make certain changes. It may be, for example, that the bodily mechanisms (e.g., metabolism) of some people may make behavioral change (e.g., dieting) largely ineffective even if the person is motivated. Should we expect these people to undergo gastric bypass surgery?
