The use of empirical research in bioethics: a survey of researchers in twelve European countries.

There is a need to evaluate the current educational programs in bioethics and to implement rigorous training in empirical research methods to ensure that 'empirical researchers' have the necessary skills to conduct their empirical research in bioethics. Also imperative is clear guidance on the integration of the normative and the empirical so that researchers who plan to do so have necessary tools and competences to fulfil their goals.
