Abstract

Guidelines for evaluating prevalence studiesAs stated in the first issue of Evidence-Based Mental Health, we are planning to widen the scope of the journal to include studies answering additional types of clinical questions.One of our first priorities has been to develop criteria for studies providing information about the prevalence of psychiatric disorders, both in the population and in specific clinical settings.We invited the following editorial from Dr Michael Boyle to highlight the key methodological issues involved in the critical appraisal of prevalence studies.The next stage is to develop valid and reliable criteria for selecting prevalence studies for inclusion in the journal.We welcome our readers contribution to this process.
