The CIM website proves that it is committed to high ethical and professional standards. It does not contain erroneous information, including any attempt to mimic another journal/publisher’s website.

Aims and scope: CIM publishes research articles dealing with the circadian rhythms in various medical fields and clinical sleep medicine. The Chronobiology in Medicine covers various biological rhythm studies, including sleep and wakefulness, in various medical areas, basic sciences and social sciences. Topics on the clinical sleep disorders such as sleep disordered breathing and insomnia influencing on the circadian rhythm disturbances will be considered for publication.

Readership: CIM is primarily for physicians, psychiatrists, neurologists, sleep medicine specialists, basic scientists and social scientists.

Authorship criteria: All persons designated as authors should qualify for authorship. Each author should have participated sufficiently in the work to take public responsibility for the content. According to criteria formulated by the International Committee of Medical Journal Editors (ICMJE), authorship credit should be based on the following 4 criteria: 1) substantial contributions to conception and design or analysis and interpretation of data, AND 2) drafting the article or revising it critically for important intellectual content, AND 3) final approval of the version to be published; AND 4) agreement to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved. All these 4 conditions must be met. Participation solely in the acquisition of funding or the collection of data does not justify authorship. All other contributors who do not meet these criteria for authorship should be noted in the Acknowledgments section. CIM does not consider people thanked in the Acknowledgements or listed as members of a study group on whose behalf a paper is submitted to be authors. CIM does accept notice of equal contribution for the first author when the study was clearly performed by co-first authors. After the initial submission of a manuscript, any changes whatsoever in authorship (adding author(s), deleting author(s), or re-arranging the order of authors) must be explained by a letter to the editor from the authors concerned. This letter must be signed by all authors of the paper. But after publication, CIM does not correct authorship unless a mistake has been made by the editorial staff. Copyright assignment must also be completed by every author.

Corresponding author(s): One of the authors should be designated to receive correspondence and proofs, and the appropriate address indicated. This author(s) must take primary responsibility for communication with the journal during the manuscript submission, peer-review, and publication process. The corresponding author typically ensures that all the journal’s administrative requirements, such as providing details of authorship, ethics committee approval, clinical trial registration documentation, and disclosures of relationships and activities are properly completed and reported, although these duties may be delegated to one or more co-authors. The corresponding author should be available throughout the submission and peer-review process to respond to editorial queries in a timely way, and should be available after publication to respond to critiques of the work and cooperate with any requests from the journal for data or additional information should questions about the paper arise after publication [].

3. Peer Review Process

All papers, including those invited by the Editor, are subject to peer review. If a manuscript does not fit the aims and scope of the Journal or does not adhere to the Instructions for Authors, it may be returned to the author immediately after receipt and without a review. A submitted manuscript will be acknowledged and assigned a manuscript number, which is to be used in all further correspondence. Before reviewing, all submitted manuscripts are inspected by Similarity Check powered by iThenticate (, a plagiarism-screening tool. Manuscripts are reviewed and given a priority based on their originality, importance of the findings, scientific merit and significance for the field, interest to readers, lucidity, and suitability for publication. Manuscripts with insufficient priority for publication are rejected promptly. Other manuscripts are sent to expert consultants for peer review. The journal uses a double-blind peer-review process such that the identities of both the reviewers and authors are kept confidential. The existence of a manuscript under review is not revealed to anyone other than peer reviewers and editorial staff. Peer reviewers are expected to maintain strict confidentiality. Reviewers are also expected to inform the Editor of any conflicts of interest, including any financial arrangements involving companies whose products (or competing products) are featured in the manuscripts they agree to review. Statistical editing may be done if the data needs professional statistical review by a statistician.
After review, the editorial board determines whether or not the manuscript is accepted for publication. Once rejected, the manuscript is not subject to further review. Once the manuscript is received by the editorial board, an e-mail confirmation will be sent to the author within seven days. The author will be notified of any delays due to evaluation difficulties. Authors may contact the editorial committee for the current review phase of the manuscript. The board will inform the author of the status of the review process.
