Any investigation in the health sciences should have a plan or proposal to answer a specific research question. This document, designed for persons preparing for or already pursuing a research project, describes the conceptual framework related with a research proposal, from the study design until its implementation. The objective of this document is to summarize different theoretical aspects that should be considered in a research project, including pertinent references that might be used to deepen the discussion. First, a series of definitions related to the scientific method are presented and then the processes to carry out a research proposal including common epidemiologic designs are illustrated. In addition, a series of research questions that can serve as a guide to perform a critical analysis of published papers are included. Finally, an interdisciplinary group integrated by health professionals with the clinical expertise and health professionals with the necessary skills in biostatistics and epidemiology to undertake a sound scientific research is recommended.
