Abstract Because translational research is not translational research and proposed an individual institutions and individual clearly defined, developers of operational definition to use in the trainees within the institutions but that it translational research programs are educational framework. In this article, must also be rigorous enough to struggling to articulate specific program the authors posit that translational document that the program is meeting objectives, delineate the knowledge and research fosters the multidirectional and its short-, intermediate-, and long-term skills (competencies) that trainees are multidisciplinary integration of basic objectives and that its trainees are expected to develop, create an research, patient-oriented research, and meeting preestablished competency appropriate curriculum, and track population-based research, with the requirements. A logic model is proposed outcomes to assess whether program long-term aim of improving the health of for the evaluation of translational the public.

many possible models of training that can provide the academic path to these goals.

Training in translational research will vary depending on the background of trainees and the areas of research they plan to pursue. Given the diversity of educational backgrounds and research interests, it will be necessary to design a customized curriculum for almost every trainee. To ensure an understanding of complementary disciplines and to enhance communication and collaboration, trainees who have focused on basic laboratory research will need to become immersed in clinical sciences and clinical practice, whereas trainees with a Figure 1 Model for translational research, as proposed by the Evaluation Committee of the Association for Clinical Research Training. clinical focus will need to gain exposure to basic science research. Both types of individuals will also benefit from training public health. Alternatively, it may potential to directly affect clinical in population-based sciences, as is suggest that patient-oriented research practice.
