Authorship

For publication of scholarly work in IJPS, authorship should be based on the following four criteria:
1) Substantial contributions to the conception or design of the work; or the acquisition, analysis, or interpretation of data for the work
2) Drafting the work or revising it critically for important intellectual content
3) Final approval of the version to be published
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.
In addition to being accountable for the parts of the work he or she has done, an author should be able to identify which co-authors are responsible for specific other parts of the work. In addition, authors should have confidence in the integrity of the contributions of their co-authors.
IJPS accepts all who meet the four criteria should be identified as authors.
IJPS designates only one corresponding author per article. Any further contribution details must be included in the contributors or acknowledgment sections at the end of the article.
The criteria are not intended for use as a means to disqualify colleagues from authorship who otherwise meet authorship criteria by denying them the opportunity to meet criteria 2 or 3. Therefore, all individuals who meet the first criterion should have the opportunity to participate in the review, drafting, and final approval of the manuscript.
The individuals who conduct the work are responsible for identifying who meets these criteria and ideally should do so when planning the work, making modifications as appropriate as the work progresses.
The corresponding author takes primary responsibility for communication with the journal during the manuscript submission, peer review, and publication process, and typically ensures that all the journal’s administrative requirements, such as providing details of authorship, ethics committee approval, and gathering conflict of interest forms and statements, are properly completed, although these duties may be delegated to one or more co-authors.
When a large multi-author group has conducted the work, the group ideally should decide who will be an author before the work is started and confirm who is an author before submitting the manuscript for publication. All members of the group named as authors should meet all four criteria for authorship, including approval of the final manuscript, and they should be able to take public responsibility for the work and should have full confidence in the accuracy and integrity of the work of other group authors. They will also be expected as individuals to complete conflict-of-interest disclosure forms.
IJPS expects that all authors included in a paper fulfill the criteria of authorship. When encountering any disagreements among authors guidance of the Committee on Publication Ethics (COPE) should be followed.

Contributorship
The IJPS lists contributors on the cover page and the first page of the article. Hence researchers or authors must determine among themselves the precise nature of each person's contribution before submitting the article.
Alteration to authorship or contributorship any change in authors and/or contributors after initial submission must be approved by all authors. This applies to additions, deletions, changes of order to the authors, or contributions being attributed differently. Any alterations must be explained to the editor. The editor may contact any of the authors and/or contributors to ascertain whether they have agreed to any alteration.

Group authorship
If there is a very large number of authors everyone should be listed and met the IJPS criteria for authorship. If they did, then it's required that the authors form a group whose name will appear in the article byline.
