In this special article we describe a number of reporting guidelines endorsed by the CONSORT (Consolidated Standards of Reporting Trials) group for a range of research designs that commonly appear in scientific journals: systematic reviews, clinical trials with and without randomisation, observational studies, n-of-1 (or single-case experimental design) trials, and diagnostic studies. We also consider reporting guidelines for studies using qualitative methodology. In addition to reporting guidelines, we present method quality rating scales, which aim to measure risk of bias that threatens the internal validity of a study. Advantages of reporting guidelines and method quality rating scales for authors include the provision of a structure by which to improve the clarity and transparency of report writing; for reviewers and readers advantages include a method by which to critically appraise an article. Brain Impairment endorses these reporting guidelines and applies them within the review process for submissions to the journal.
