The current JARS–Quant standards, released in 2018, expand and revise the types of research methodologies covered in the original JARS, which were published in 2008.
JARS–Quant include guidance 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 JARS–Quant 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 Psychologyopens in new window.
