Journal Article Reporting Standards (JARS)
Quantitative Research Design (JARS–Quant)
The current JARS–Quant guidelines, released in 2018, expand and revise the types of research methodologies covered in the original JARS, which were published in 2008.
JARS–Quant includes guidelines for manuscripts that report
- Primary quantitative research
- Experimental designs
- Nonexperimental designs
- Special designs
- Analytic methods
- Meta-analyses
In addition, JARS–Quant now divides hypotheses, analyses, and conclusions into primary, secondary, and exploratory groups. This should enhance the readability and replicability of the research.
Providing the information specified in the JARS–Quant guidelines should become routine and minimally burdensome, thereby increasing the transparency of reporting in psychological research.
For more information on how the revised standards were created, read Journal Article Reporting Standards for Quantitative Research in Psychology.
