Individual Differences Research (IDR), founded in 2003, is a peer-reviewed scholarly journal publishing high-quality research across the psychological sciences. The journal places particular emphasis on how individual variation across traits, processes, contexts, and life stages shapes psychological functioning, behavior, and outcomes. IDR welcomes empirical, theoretical, and methodological contributions spanning major areas of psychology, including personality, cognition, social, developmental, clinical, and related fields.
While grounded in an individual-differences perspective, the journal also encourages work that connects psychology to adjacent domains such as education, health, neuroscience, and behavioral science, especially where individual variation informs theory, measurement, or application.
IDR publishes one volume annually. Beginning in 2026, the journal adopted a rolling-issue publication model in which articles are published online on a continuous basis following acceptance and subsequently assigned to an open issue. This model enhances discoverability and indexing compatibility while maintaining rapid online publication.
Originally established as a print-based journal, IDR has been published exclusively in electronic format since 2015. All prior volumes have been digitized and are freely available as open-access publications.
