I want to read studies that measure the efficacy of health education in producing behavioral outcomes.
My naive assumption has been that most health education has few objective affordances nor lasting benefits. I would like to confirm or correct that assumption with data.
By health education I mean anything that informs consumers about health risks and conditions for purposes of prevention or self-care. Academic, clinical, governmental, social, instructor-led, self-paced, online, printed, video etc.
What techniques are deemed effective; what is the evidence for that belief?
