Standards on how to develop and report systematic reviews in Psychology and Health

Systematic reviews are secondary studies that summarize the best scientific evidence available by means of explicit and rigorous methods to identify, select, appraise, analyse and summarise the empirical studies that enable responding to specific questions. The aim of this theoretical study is to set out a series of standards and recommendations for the planning, development and reporting of a systematic review in the field of the health sciences. The article describes the systematic reviews in the context of practice based on scientific evidence, their rise, justification, applicability and differences compared to traditional literature reviews. Secondly, the methodology is set out for their development and guidelines are established for their preparation; the stages of the process and preparation of a protocol are described with emphasis on the steps to follow to prepare and report a systematic review. Finally, some additional considerations are set out for their preparation and publication in a scientific journal. This guide is aimed both at authors and reviewers of a systematic review.
