Starting from this issue of Epidemiologia e Psichiatria Sociale a new Section, called ABC of Methodology, will regularly cover methodological aspects related to the design, conduct, reporting and interpretation of clinical and epidemiological studies. We hope that these articles will help develop a more critical attitude towards research findings published in the international literature and, additionally, we wish to help promote the implementation of original research projects with higher standards in terms of design, conduct and reporting.
