More Americans are changing their behavior when it comes to taking care of their health, according to a new EBRI Health Confidence Survey underwritten by Des Moines, IA-based Principal Financial Group. The survey of 1,000 people indicates that Americans are showing some level of personal responsibility through heightened awareness and action: Two out of five Americans report they are often or always aware of the cost of a doctor's visit. "The economic crisis is serving as 'the tipping point' in terms of how Americans are changing behavior concerning their healthcare," said Jerry Ripperger, practice leader of consumer health at Principal.
