Regular issues include two types of articles: empirical articles and review articles. Empirical articles report data from single or multiple studies in one of the major fields of scientific psychology. Review articles provide overviews of the international literature on a particular topic; authors are especially encouraged to include in their review relevant publications from regions of the world not typically cited and/or not published in English. Special topical issues or sections are also published two or three times a year. All articles include a detailed abstract in English, French and Spanish.

The International Platform for Psychologists
Associate Editors: M. Bullock (USA) and P.L.-J. Ritchie (Canada)
Many of IJP's issues include a second section, the International Platform for Psychologists, which provides an opportunity to exchange news and opinions on psychology as an academic and applied profession. This section also contains information about the IUPsyS, about major international meetings, and about the activities of the National Psychological Societies. Finally it offers an opportunity to express opinions and to discuss internationally significant psychological issues. There is also a United Nations section with the International Platform for Psychologists.
