How to format your references using the Psychometrika citation style

This is a short guide how to format citations and the bibliography in a manuscript for Psychometrika. For a complete guide how to prepare your manuscript refer to the journal's instructions to authors.

Using reference management software

Typically you don't format your citations and bibliography by hand. The easiest way is to use a reference manager:

Paperpile	The citation style is built in and you can choose it in Settings > Citation Style or Paperpile > Citation Style in Google Docs.
EndNote	Find the style here: output styles overview
Mendeley, Zotero, Papers, and others	The style is either built in or you can download a CSL file that is supported by most references management programs.
BibTeX	BibTeX syles are usually part of a LaTeX template. Check the instructions to authors if the publisher offers a LaTeX template for this journal.

Journal articles

Those examples are references to articles in scholarly journals and how they are supposed to appear in your bibliography.

Not all journals organize their published articles in volumes and issues, so these fields are optional. Some electronic journals do not provide a page range, but instead list an article identifier. In a case like this it's safe to use the article identifier instead of the page range.

A journal article with 1 author

Carpenter, S. (2008). Science careers. Finding industry funding. Science (New York, N.Y.), 319(5869), 1550–1551.

A journal article with 2 authors

Forster, P., & Renfrew, C. (2011). Evolution. Mother tongue and Y chromosomes. Science (New York, N.Y.), 333(6048), 1390–1391.

A journal article with 3 authors

Royle, N. J., Hartley, I. R., & Parker, G. A. (2002). Sexual conflict reduces offspring fitness in zebra finches. Nature, 416(6882), 733–736.

A journal article with 8 or more authors

Kangaspeska, S., Stride, B., Métivier, R., Polycarpou-Schwarz, M., Ibberson, D., Carmouche, R. P., et al. (2008). Transient cyclical methylation of promoter DNA. Nature, 452(7183), 112–115.

Narodoslawsky (Eds.), Integrated Spatial and Energy Planning: Supporting Climate Protection and the Energy Turn with Means of Spatial Planning (pp. 55–72). Cham: Springer International Publishing.

Web sites

Sometimes references to web sites should appear directly in the text rather than in the bibliography. Refer to the Instructions to authors for Psychometrika.

Blog post

Reports

This example shows the general structure used for government reports, technical reports, and scientific reports. If you can't locate the report number then it might be better to cite the report as a book. For reports it is usually not individual people that are credited as authors, but a governmental department or agency like "U. S. Food and Drug Administration" or "National Cancer Institute".

Government report

Government Accountability Office. (1985). Institutional Aid Under Title III of the Higher Education Act of 1965 (No. 127541). Washington, DC: U.S. Government Printing Office.

Theses and dissertations

Theses including Ph.D. dissertations, Master's theses or Bachelor theses follow the basic format outlined below.

Doctoral dissertation

Thompson, T. (2010). Assessing the determinants of information technology adoption in Jamaica’s public sector using the technology acceptance model (Doctoral dissertation). Northcentral University, Scottsdale, AZ.

News paper articles

Unlike scholarly journals, news papers do not usually have a volume and issue number. Instead, the full date and page number is required for a correct reference.

New York Times article

Wagner, J. (2016, September 4). Looking the Part of a Mets Starter, a Rookie Delivers. New York Times, p. SP2.

In-text citations

References should be cited in the text by name and year in parentheses:

This sentence cites one reference (Carpenter 2008).
This sentence cites two references (Carpenter 2008; Forster and Renfrew 2011).

Here are examples of in-text citations with multiple authors:

Two authors: (Forster and Renfrew 2011)
Three or more authors: (Kangaspeska et al. 2008)
