The Shanghai Archives of Psychiatry is committed to continually improving research methods in psychiatry, to promoting the use of evidence-based methods in the treatment of mental disorders, and to introducing novel methodological approaches to the psychiatric research community. To this end, with this issue we are inaugurating a new ＇Research Methods in Psychiatry＇ section of the journal. These papers will focus on methodological issues related to all types of mental health research including basic animal studies, clinical studies, large-scale epidemiological studies, and policy studies. Articles about the development and evaluation of questionnaires or other instruments and articles that present the methodological background for large multi-center studies will also be included in this section. Authors interested in contributing to this sect-ion of the journal should refer to the corresponding part of the Instructions to Authors on our website or contact the editor for this new section, Hui Cheng （chengyaojin@ yahoo.corn）.
