Belief in the need for the medication
Belief that the medication will help Belief that the medication is safe;
side effects unlikely or minimal
Conclusions
Don’t yet fully understand how beliefs function –impact is probably not constant across people, conditions, medications.
Don’t yet know how to change beliefs.
Next steps…
Better understanding of mental models– What affects perceptions of need? – What affects perceptions of safety?– What affects perceptions of benefit?
Strategies for changing beliefs– For physicians– Print/media/web materials
