a. Clinical Trials
Authors must submit original protocols as supporting information to allow editors and reviewers to assess manuscripts fully. Any deviation from the protocol must be explained.
We require that authors of clinical trials adhere to the CONSORT reporting guidelines appropriate to their trial design. Please check the CONSORT statement Web site (http://www.consort-statement.org/) for information on the appropriate guidelines for specific trial types. All reports of the results of randomized clinical trials should include the CONSORT flow diagram as Figure 1, and authors should complete and submit the checklist contained within the CONSORT statement. Information on statistical methods or participants beyond what is indicated in the CONSORT statement should be reported according to the specifications indicated in the Methods section under Preparation of Manuscripts.
Psychiatry Investigation supports the position of the International Committee of Medical Journal Editors (ICMJE) on trial registration. All trials initiated after 1 July 2005 must be registered prospectively in a publicly accessible registry (i.e., before patient recruitment has begun), or they will not be considered for publication. For trials initiated before 1 July 2005, all trials must be registered before submission to our journals. The trial's registration number must be provided at the time of submission.
b. Systematic Reviews and Meta-Analyses of Randomized Controlled Trials
Reports of meta-analyses of randomized controlled studies should use the QUOROM statement as a guide (Moher D, Cook DJ, Eastwood S, Olkin I, Rennie D, Stroup DF. Improving the quality of reports of meta-analyses of randomized controlled trials: The QUOROM statement. Lancet 1999;354:1896900), and should include a copy of the QUOROM checklist.
c. Epidemiological Studies
For reports of epidemiological studies, you should consult the STROBE initiative (http://www.strobe-statement.org/).
d. Microarray Experiments
Reports of microarray experiments should conform to the MIAME guideline (http://www.mged.org/Workgroups/MIAME/miame.html) and the data from the experiments must be deposited in a publicly accessible database.
