Format and Structure of a Research Article

Concept

Most scientific articles follow the IMRaD structure: Introduction, Methods, Results and Discussion, preceded by the title, abstract and keywords and followed by the conclusion, acknowledgements and references. The Introduction tells why the study matters (background, gap, objective); the Methods section tells how it was done in enough detail for replication; the Results section reports what was found without interpretation; the Discussion explains what the results mean, compares them with earlier work, admits limitations and states implications. The overall shape is like an hourglass, moving from the general field to the specific study and back to general significance. Abstracts and conclusions are usually written last.

Concept

A good title is concise, specific and informative, contains the key variables, and avoids unexplained abbreviations. The abstract is a stand-alone summary of the purpose, method, main results and conclusion, usually 150 to 300 words, containing no citations and no new information. It may be informative (structured under headings) or descriptive (indicating what the paper covers). Keywords, usually three to eight, are the terms by which indexing services and search engines retrieve the paper, so they should be standard terms rather than the title’s words alone. Some journals also ask for a graphical abstract or highlights.

Concept

An original research article reports new data and is the main type. A short communication or brief report publishes preliminary or limited findings quickly. A review article summarises and critiques existing literature, and may be narrative or systematic; a meta-analysis pools results statistically. A case report describes a single case in detail. Other items include letters to the editor, commentaries and editorials (opinion pieces), perspectives, technical notes, conference papers and book reviews.

Concept

Peer review is the evaluation of a manuscript by independent experts before publication, to check validity, originality and significance. The usual path is submission, editorial screening (a weak paper may be “desk rejected”), assessment by reviewers, an editorial decision (accept, minor revision, major revision or reject), revision with a response letter, and proofs. In single-blind review the reviewers know the authors but the authors do not know the reviewers; in double-blind review both are anonymous; in open review identities (and sometimes reports) are public. Its weaknesses are delay, reviewer bias and inconsistency, and the Committee on Publication Ethics (COPE) provides guidelines for editors and reviewers.

Concept

Identifiers make scholarly output traceable. The ISSN (International Standard Serial Number) is an eight-digit number identifying a periodical, with separate numbers for print and electronic forms; the ISBN identifies a book and has thirteen digits since 2007; the DOI (Digital Object Identifier) is a permanent link to a particular article; and ORCID is a persistent sixteen-digit identifier for an individual researcher. Metrics rate journals and authors: the impact factor (Clarivate, two-year window), CiteScore (Scopus, four-year window), SJR (weights citations by the prestige of the citing journal), SNIP (normalises for field differences), the h-index and i10-index. In India the UGC-CARE list (Consortium for Academic and Research Ethics) identifies quality journals.

Concept

Predatory journals exploit the author-pays model: they charge fees, provide little or no genuine peer review, make false claims about indexing or impact factor, spam researchers with invitations and promise very quick acceptance; the term is linked with Jeffrey Beall’s lists. Safeguards include checking indexing in databases, membership of DOAJ and COPE, and the “Think. Check. Submit.” checklist. Duplicate submission means sending the same manuscript to several journals at once; redundant publication means publishing the same findings twice; salami slicing splits one study into several thin papers. Authorship should reflect substantial contribution: the ICMJE criteria require substantial contribution to the work, drafting or critical revision, final approval and accountability. Ghost authors contribute but are not named; guest or gift authors are named without contributing.
