Is the instrument available? Benjamin Littenberg, University of Vermont 18 February 2007 I found this article interesting and a potentially valuable contribution to the field of Health Literacy. However, I was disappointed that the instrument was not included in the article. It is very difficult to understand the strengths and weaknesses of a survey instrument that you can't look at. Is the instrument available?Thank you for your good work!Benjamin Littenberg, MD, Henry and Carleen Tufo Professor of Medicine & Professor of Nursing Director, General Internal Medicine, University of Vermont Competing interests None.
