(a)Although statistical differences in mean scores were not found between the different departments in the simple linear regression analysis, they were found between medical departments and the remaining 3 after adjusting for sex, postgraduate education, and physician category. (b)Statistical differences in mean scores were found between Italians responders and the other physicians in the simple linear regression analysis. This difference remains after adjusting for sex, post-graduate education and physician category.
