If you are using Protection Motivation Theory to promote behavior change, why is self-
efficacy expectancy important?
If people expect the change to result in immediate self-improvement, they are more likely to try it.
If people don't expect the new behavior will work, they won't try it.
If people don't expect they will be able to do the new behavior, they won't try it.
If people expect the change will make them healthier, they are more likely to try it.
