Individual Differences Research (IDR) publishes original scholarly work across the psychological sciences, with an emphasis on how individual variation shapes psychological processes, behavior, and outcomes. The journal is dedicated to advancing both the science and application of psychology by fostering research that illuminates meaningful differences among individuals, groups, and populations.

IDR primarily publishes quantitative research; however, high-quality qualitative, theoretical, conceptual, and mixed-methods manuscripts are also welcomed when they make a clear contribution to psychological knowledge. Submissions may be empirical, theoretical, methodological, or integrative in nature, provided they demonstrate scholarly rigor, conceptual clarity, and relevance to the journal’s scope.

The journal welcomes research spanning all major areas of psychology and closely related disciplines, including but not limited to, personality and individual differences, cognition and intelligence, emotion and affective processes, motivation and self-regulation, social and interpersonal behavior, developmental processes across the lifespan, learning and change, stress and health, clinical and psychopathological phenomena, perception and attention, and biological, physiological, and neuropsychological foundations of behavior.

IDR publishes both full-length articles and brief reports. Regardless of format, manuscripts should clearly articulate research objectives, theoretical rationale, and expected outcomes; describe methods in sufficient detail to permit replication; present appropriate data analyses; and interpret findings within the context of existing theory and empirical literature.

Consistent with its founding mission, IDR is receptive to all meritorious psychological research. The journal actively encourages submissions on traditional, emerging, interdisciplinary, and niche topics, including work that challenges prevailing assumptions or explores underrepresented areas of inquiry. IDR strives to maintain an open, fair, and constructive editorial process and welcomes submissions from scholars at all career stages and institutional affiliations.
